This was an incredibly challenging video to make. The challenge came with getting the Navy to agree to the interview in the first place, then successfully navigating the interview without it being shut down. In the end, everyone was super professional and it was a really fun topic to learn about! I hope you enjoy, and thank you very much for considering becoming a Patron at (www.patreon.com/smartereveryday)!
I love how he's like "no no, this is in this and so document, its declassified. I can get the manual if you want" You can tell how much he loves his job and loves to talk about it :)
I am a Navy vet and I will tell you one thing that is true about every sailor, we love proving our superiors wrong. I used to walk around with multiple policies in my pocket because there are "old" policies that higher ups still think are enforced and they have been changed or they simply don't know about. for example: I was a sailor who was sent to Iraq to help support Army operations, we wore Army uniforms, Army uniforms have some different standards for wear than Navy uniforms. Instead of issuing a whole new set of regulations for the uniforms the Navy simply issued a policy to basically state "The Navy members who wear Army uniforms will follow the Army rules for wearing said uniforms". My favorite was for backpacks, in the Navy the backpack had to be black or dark blue and could only be worn slung over one shoulder or carried. You could not wear a laptop bag slung over a shoulder or across the chest it had to be carried. The Army on the other hand didn't care how you wore the backpack as long as it was black and left your right hand free (for saluting) and laptop bags were authorized to be worn accordingly and had to be black. When I got back from Iraq I still had to wear my Army ACU's because they told us to leave all our other uniforms at home. I was waiting to transfer to my next command and the amount of times I had to whip out the regs because some Chief or Officer would stop to scold me for wearing my laptop bag was unreal. The satisfaction I got watching many a blood vessel bulge in some chiefs foreheads was immeasurable though. most were cool and were like "oh cool, lemme write this down so I can tell the other chiefs"
"No its not, I can show you the manual where its declassified." The sign of a professional that takes their job seriously. Good for him and the guy supervising him. If a supervisor is willing to be challenged without taking it personally everyone achieves more.
Absolutely correct. I'm not on their level but I love it when my soldiers are able to tell me I'm wrong. It doesn't hurt me, it informs me and tells me that they're trying to be better than me which keeps me on my toes.
There is Stuff - fairly common everyday Stuff, not this "Cold War-Spy-Stuff" rather than f. E. the Time Plan for the Mess Hall - that is classified. And, there is also Stuff, you are not even allowed to answer in any Way - so also not denying it. It is often People say something Stupid just to avoid any further Questions and even "keeping silent" would be too much of an indicator. Knowing this, mainly all you can find on YT and such is outdated (WW1-Trechtactics), common knowledge ("THAT WAY ROUND you have to hold the Rifle. THAT WAY!") or common Sense ("All the Guys around you wear blue. Your Arm you see on Screen seems to wear Blue. So guess what you gotta do with the Red ones and what not to do with the blue ones?"). In that case, the Conversation went pretty fast into "How to find out and seperate Contacts" - which is highly classified - and so the Guy showed his CO "'s all right, I know how to handle this" and just went over to the Basics, away from the deep questions. Also, that Way he provided all Answers and everybody knew that any further Questions go into the "No-Go-Zone". I am more impressed of his Leadershipskills which I had not expected from this Guy.
@@JRSLover411 This is valid in any boss role, a good boss can handle being challenged and you want employees that are as good or better in they specialty, your job is to get them to be their best, not to best them :)
destin in such an underrated interviewer. the amount of stress there is in such a interview in which a lot of the questions he’s asking can’t be answered without leaking classified information is amazing and the way he handles himself and asks all these great questions in such a situation is even more amazing. great job man.
also, if i remember correctly, he has worked on military projects which are definitely classified. so he understands the background behind these things.
Pretty sure they pre-briefed him on what he could and couldn’t talk about. I don’t think they would have let a RUclipsr with a camera aboard an active nuclear submarine without laying down some ground rules before he showed up. He only makes note of it so the audience can keep up.
nah. completely over stated. everything destin asked is public knowledge. the only things clasified would be actual boat capability. all the concepts are the same. its the detail that the boat can get thats class.
I’m an electrical engineer and I used to work on the Virginia & Los Angeles class submarines to test for electromagnetic interference. I worked in the radio room, the electronic surveillance room, and the control room testing EMI levels on all types of systems on the subs. I got to see how the sonar worked, while sitting alongside the ship’s crew. Being in the control room was INSANE! I even went on sea trials with these guys, ate & slept with them for a whole week. It is definitely an experience that I’ll remember forever. Talking with the crew members about their lives and getting to know them like everyday people was an even better experience. Thanks for sharing this Destin.
@@andrewmarthie5062 lol it’s “no-go” for a reason, especially on the internet, which could risk these guys lives. Not trying to get the DON on my case 👀
That dude reaaaally loves his job, Exhibit #1: Glimpses of nerdy enthusiasm being shut down by his professionalism and responsibility. Exhibit #2: Exact de-classified manual to continue the conversation - "I can go get it right now!" LMAO, this also shows he's under good leadership, in the sense that he was willing to challenge his supervisor. The constant tension in the room shows this was the real deal, good content, earned a sub.
That "unwrapping" of the polar coordinate graph was an absolutely ingenious way to get people onboard who may have never been exposed to polar coordinates before. I absolutely love this channels educational animations. Destin is just one of those people who could explain any topic to you in a way you can understand and feel like you've learned something, and the constant high quality visuals just make literally anything the man talks about interesting.
The best part was how disinterested he seemed until it was obvious you were understanding and genuinely interested in what he was saying. He opened up, smiled more, and became very passionate as he spoke. I see this is so many engineers, and especially Destin in every video.
An introverted life. Dull, bland and quiet... UNTIL you get them talking about their passion. We become animated, excited & completely different people. Want to see a reclusive person do a happy dance in public? Be like Destin in this video: listen, engage & deep dive in the subject matter.
This is about normal for bubbleheads, worked alongside them for awhile when i was in the Navy, weird guys but super smart. so smart they cant walk across the street unsupervised.
For lower-ranking, non-lifer blueshirts (i.e. not chiefs!!!), that phrase is addressed to the high-ranking officer as, "OH, SIR! I will SO bet you! I will bet you MY REMAINING ENLISTMENT, RIGHT NOW! Promise me my DD-214 and I'll GO GET THE MANUAL!!!" Heard it sooooo many times. Don't bet against the guy who owns the gear!
@@funkmonsterjones4753 it's more effective at recruiting or getting kids interested in science/engineering/math which is ultimately Destin's goal. This isn't much of a show of force video. They use videos of missile launch tests and war games for stuff like that, not simple explanations of stuff that literally every sea-faring nation on Earth has known for decades.
@@funkmonsterjones4753 No one who is even midly interested in military power would be surprised by anything that is said/shown in this video. The USA has nuclear submarines in the Artic? Who would have thought about it, right?
@@tinchote It's the fact that this stuff is for civilian consumption. The military is usually twenty years ahead of whatever is declassified, so this video sets the bar. If Iran or NK are 10 years ahead of this, they can estimate that they are 10 years behind us. It's also scary for them to know how many American civilians actively educate themselves about military hardware and tactics, and that those people form communities who share intelligence with each other. Propagation of information is one of our strong suits. Especially among teenagers. That suggests a future where young Americans are more ready for war than our adversaries. All of these ideas add up to a great deterrent. Funk is right. Dustin himself realized his video on the Future of Warfare was a weapon in the cyber domain, just one of the domains of modern wars, and it's the one the military needs civilian help to operate in.
I love how Garrett just started nerding out with Destin. Even pushing back on the executive officer about classified status to go into more detail with him
That's one thing I loved about being in the Navy. The best officers were not afraid to admit when they were wrong, and encouraged the senior enlisted and other officers to firmly, but politely, challenge them, like how the Chief challenged the XO.
I loved the "I'll show you the manual" part. Sounds like the type of stuff I say all of the time and people just call me an @$$. "No, really, just listen--I'm right."
"It's unclassified, it's in an unclassified manual, I'll run over and grab it for you right now." Man, this guy loves his work. Wish I had a job like that.
questionable, he's a submariner, they all hate their lives, they're just there to survive their deployment and see the sun again and maybe get some fresh air and some puss
@@desolater010 Lots of folks, perhaps most, end up in the job they can get, the one that they perceive as attainable. I know where I'd like to be, but often I don't know how to get there from where I am. OR, I might know that I need 6 years of college (that I can't afford) while I have to work a job that pays enough to support my family. Often, the course we are on is set by decisions we made years ago when we didn't understand all the ramifications or couldn't see the larger world. Sometimes those decisions were made for us by our parents.
as a sonar op myself, you did an amazing job at explaining something very complicated in a simple way, wait until you learn about passive narrowband and doppler effect!
i love doppler effect. whenever i experience it I just perk up and I'm like "there's physics in action" Ambulances and music turning eerie and slow are my favorites
@@foobarmaximus3506 we all already know about the Doppler effect, we just didn't think about it and how it is used in combination with all the confounding factors like lensing, multipath, etc. Simple radar/sonar is simple. Send a ping wait for response for ranging, listen using a phased array antenna for direction. But once you add in one or two or five confounding physics phenomena, rotating reference frames, the Doppler and lensing, etc, this stuff gets real hard to visualize real quick, and you need some signal processing to help you out.
I was hoping they would get into the towed arrays and other things related to that subject. But I’m sure not much of that would make it into the video. I’m surprised they let that much on passive sonar make it into the video. Everyone thinks about pinging sonar when they hear the term sonar. Not sure if the SOSUS will be able to get much attention in this series.
Is it ALL sound based or are there electromagnetic (I guess it would be radar) options too? Obviously under water the frequency bands used would need to be different, but is there any EM based stuff like that on subs?
well - that's an easy one - submarine is just some fancy new english term the Beatles came up with in the late 60s to not have it mistaken for a german u-boat ... aw - sorry - I know that's not as funny as yours - but hey, at least I gave it a try ^.^
@NICK IS AWESOME, best ask John Phillip Holland...... that guy described it as a ship that sinks.... but more importantly, re-floats! Interesting Guy ....
This is one of those channels that makes the internet so valuable. Through Destin and his learning/teaching journey, he allows us to meet people and experience things that in no other way would the average person be able to do. Climbing aboard a US nuclear sub? Never thought I'd see the inside of one. Even more of a pleasure to meet the people on board vicariously. Thank you Destin for the work you do, it really is important.
I am a former sonarman on an Arleigh Burke class destroyer, and I must say that this is a very good video when it comes to explaining what I used to do in the Navy as an STG 2 Sonar Supervisor. Yes, lots of math and knowing the "signature" of every single ship and sub that exists (or at least those that we know of), plus all of the biologics and underwater topography (and oceanography). It does take a lot of mental aptitude to first identify the contact that you're hearing (you need to know the specific frequencies that every vessel emits into the water), and then you need to do the trig to actually figure out where it is in the water (i.e. time and space), and what direction it is moving (and at what relative velocity). And you must do this using only heard frequencies in the water, while also allowing for real-time changes on our part or theirs. We generally had 3-5 minutes to first identify the contact, and then another 5 minutes to determine where it is (and what speed/heading it was on). By the time that I left the Navy, the buttons on my calculator were worn entirely unreadable (and I bought it brand new when I checked aboard my ship). I did two deployments to the Gulf, plus an INSURV. My ship came in second for the Bloodhound Award after INSURV.
Here's a question for you: how much does having a discerning ear come in handy as opposed to math skills? Is it more important to pick up the subtleties in sounds or to be able to crunch through a bunch of raw data?
@@margotrosendorn6371I can’t speak for submarines, because I’ve never worked on one. On a destroyer however, you will rarely have to listen to the information you are receiving. The important parts of the data you need to process and identify will be in front of you on your monitor.
My fellow STGs and I got a chance to go check out combat systems and sonar on the Arleigh Burke and we were so dejected when we got back to our sonar suite on our frigate.
@@margotrosendorn6371It's all about data. You can't do it without the math. You have formulas and equations to apply to every frequency in hertz to again apply to various equipment, blade rates, types of propeller blades, number of blades, auxiliary equipment, speed, etc that would be impossible otherwise. You crunch the numbers and check your frequencies to determine exactly What type of contact you have. Actual "hearing" doesn't even come into it.
I'm starting to get a better appreciation for how busy Destin was when he was on the submarine for 24 hours. Fire drills, pizza night, sonar diagrams, getting stuffed in a torpedo tube, and I can't wait for [REDACTED].
@@phillxor He says in another video that he's hot racking with either the CO or the XO. I don't know exactly how long but I'm pretty sure it was more than 24 hours.
Honestly, I'm kinda impressed by that too. I understood it when Destin explained it, but the fact that he got it from what little the guy told him is genuinely impressive. Though, I suppose he perhaps had an idea already and it just pushed it forefront in his mind.
@@SondreGrneng Because nearly every fps game have bearing markers to help you keep track of where objectives are without you having to open minimaps? Have you played any?
Thank you Destin!! My grandfather always dreamt of being a submariner in the Navy. He had medical conditions which rendered him "Non-serviceable" and has been devastated for the past 40+ years that he was never able to realize and accomplish his dream. I've put all of your Submarine videos on a disc for him and my grandmother has told me that he has studied these videos religiously. He now feels closer than ever to being a submariner and is in absolute LOVE with this series. Thank you for allowing his dream to become somewhat of a reality vicariously through you! Much love and Holiday Blessings from Texas. We ARE Smarter Every Day with your channel. Thank you and God Bless you and your family.
"In terms of understanding, how am I doing though?" "you're pretty good" "I'm like at kindergarten though?" "That's all we want you to know." that smirk at the end, I lol'd
@@smartereveryday Thank you for what you do. You were asking all the right questions and I'd suggest reading about target motion analysis, you would find it very interesting.
Smarter Every Day is the only channel where I can learn about pecans with dad AND potentially dangerous military information in the same place and that’s the kind of content I need
@@aligatorsandcrickets Thanks to you and my curiosity and ongoing quest for all available unprofitable information, I have discovered that alligators eat crickets. Thanks!
Submariner 1. knows what he is doing 2. knows very well he even mentions the source material book name. (and knows classified or not) I call it he professionally nailed it.
If you ever talk to anyone that has worked on a sub the level of knowledge retention is truly amazing. They can legit regurgitate pages and pages of procedures and documentation.
This was so much fun to watch as a former Submarine Sonar Tech STS2/SS on the same class of boat I was twisting with the Chief as to how I would answer without tipping my hand. Knowing the answers gave it twice the entertainment value. Thanks for the video, I now have another great place to point friends that want to know what I did on the boat.
Maybe you could provide some insight, then... why was there so much handwringing about revealing classified info, when it seemed that they were literally just explaining what sonar is and how it works? I mean this was mostly wave dynamics, surely this has long been taught in engineering courses, and at no point were they describing the capabilities of the vessel... so what gives?
This sub videos someties feel like some of the submariners wish he'd be on the ISS instead of asked them questions. They are friendly, but there is sure some unease when Destin asks questions, especially in this video.
How come I can sit here for 26 minutes and actually focus and learn but when it comes to online school I struggle😂. Just shows you do such an amazing job
It's because he makes it intresting. Some guy with a monotone voice spouting equations isn't intresting, but some guy with a fascination genuinely enjoying it is
Because you're not learning. People watch these videos on RUclips and then think they're super confident about whatever it is--that they now can do or understand the thing. But studies have shown that after about 24 hours to 1 week, you've learned nothing. Further, we tend to overestimate our ability to understand or do things when we watch other people do them in videos. "Oh I can do that--it's simple now that I know how". But knowing how and actually developing the physical or mental ability to perform that task are very different things.
I like chief's deadpan response to XO where he's like " I can go get it if you want..." haha. The content you are able to deliver on this channel is really amazing.
@@Sorent1993 I remember when I was briefed on classifications they said “even if it’s unclassified and you can find it on Google, don’t tell them they can find it on Google.” Lol.
@@Willaev If it's unclassified, it's unclassified and can be released to individuals without a clearance. If it's classified even if you can find it online, you do not confirm that the information is correct or tell people where they can find it.
Destin, I just wanted to thank you for making this video. My grandpa was a Commander in the US Navy and was heavily involved in testing sonar under the ice caps after WWII and into the Cold War. I was always so curious about what he worked on that was so top secret he could never tell us what he did. All we knew was that it must have been important because in 1999, on a bike tour around the world, he opted out of the portion in Russia because he feared there would still be people after his research. He passed away several years ago, but this video has brought me closer to understanding what my grandpa worked on. So thank you for teaching me more about my family! P.S. One story he could tell us was about when he was being chased by a polar bear while carrying 50lbs of sonar equipment. He went back the next day to measure his footsteps and each one was between 12-15 feet apart!
I think he discovered a new training plan for Olympic track and field athletes. Forget about training at high altitudes to build lung capacity! Just keep out running the polar bear! Whoever's left makes the team.
My grandad was a civilian contractor for the Navy, with Westinghouse-the company that made the Navy’s nuclear reactors. My grandad’s specialty was metallurgical engineering, specifically, how the structure of metal alloys changes under the intense nuclear radiation found inside a reactor, and how to detect those changes. So he actually helped to design the reactor vessel on the USS Nautilus...something we didn’t learn until many years later, once that reactor design had become obsolete.
One way you can potentially solve the multi-return issue is using what's called a band-pass filter. If you know what the object you are hunting is made of, you can anticipate the frequencies that will have the highest energy on return. Steel will return different dominant frequencies than say ice or mud. You can frequency filter your return data to give you the true target.
I imagine if you have a passive cue you can at least filter out the active returns that arent in a similar azimuth/elevation as as the passive cue. But still, the passive cue has it's own multipath problems. Its like, if you know where it is, you know where to look, but if you know where it is you dont need to look. Hmm. Im sure there are fancy computers that take all these things into account and fuse the data from multiple sensors and narrow down the error possibilities automatically. Neat stuff.
@@spencerquimby4726 seriously though if I should delete that I will. Im not in the Navy and not read into any Navy programs. Just asking questions that came to mind.
That guy was not a supervisor. He is an Officer and it is just a 2nd set of eyes to make sure it didnt go off into something that could expose classified info. Just worked as a backup.
@@Torpedomtb At first I thought the executive officer being there was pointless. The Navy was going to sanitize all his data, but that wouldn't help if he learned something with the camera off. I'm surprised he wasn't just given a list of questions that were okay to ask.
@@fukkitful Yea it was pointless, the sonar sup is the highest expert on the topic on the ship. XO is like middle management, so he had to be there even knowing he doesn't know the topic. I do wish he gave more info as he was still far away from the line on many aspects, but seems the sonar sup was too scared to do that (don't blame him) since even public info can be class'd and while you can google it if he talks about it he'd be in jail.
so dave no body talk about sonar SIZE LIMIT !! i mean contact size limit.. like no body. does this classified ?? can sonar detect small things like 10 cm fish ?
@@moustafarefaat6155 remember, he's discussing passive sonar, so the 'brightness' of his contact isn't based on size, but sound level. So, in dog units, a chihuahua-fish would be much brighter than Labrador-fish on the screen because of their sound output. There are some stunningly noise little critters in the water for their size.
Fascinating watching this as a sonar technician in the navy. Most of the things they discuss are the basics and I can infer the things the chief can’t talk about but it’s cool seeing a civilian trying to decipher and create a picture on how we operate.
@@kekistanimememan170 well its ofcourse also about what Destin learns (or rather is not allowed to learn) off camera, not just about what we get to see
@@catseyes2334 oh yeah. AN ANother, archetypical Internet victim of zee damned Gulag. And of course "God bless America", because how it is possible to not finish like that?
The bearing rate graph was a mind bending realization for me. Especially when the sub started to rotate 360° and the surrounding craft were plotted around it. I now have an immense respect for these submariners.
"Did you find this information entertaining and accurate?" "I can neither confirm nor deny." I was docked next to the Toledo. USS Springfield SSN 761I This series brings back some fond memories. Keep up the good work. Merry Christmas and a Happy New Year to all.
@@smartereveryday I'm a huge fan and am having difficulties believing I actually got a response from you. As a member of the submarine community, I am in love with this series. I appreciate the work you're doing and love knowing you're helping people get smarter every day.
@@Smokeyxz Thank you for paying your taxes... helps to keep the military world going 'round. I hope you had a wonderful holiday season, Sir. I agree, Destin is pretty great.
Is your name really spelt with an ash like that? very cool if so. it's a shame we don't use æ anymore because it's a nice looking letter with a nice sound.
The progress from "you're partially right but mostly wrong" to "it's 100 percent unclassified manual, I can go grab it if you want" shows that with humbleness and right attitude in a conversation you can win anyone over! Dustin you're amazing!
As a submariner, you did a great job on this video. The bearing over time visual was a great product that gives people a way to see what we see on board. Also great job explaining how sound works. There's so much that goes into it but you did a great job. Bravo Zulu 👏👏👏
@@dean3188 Operational and national safety obviously. If the methods and functions of equipment were to be leaked, it could lead to exploitable vulnerabilities. You also have to account for the unforeseable. Someone might exploit information that seems harmless. So keeping a tight lid and some obscurity around information is adding a layer of safety.
When you’re on the boat you deal with varying levels of classifications and declassified info that it’s hard to remember sometimes what is classified and what isn’t.
@@brucepreston3927 It certainly takes practice, but there are plenty of sub simulators out there that use bearing rate graphs. I don't claim to be an expert, but after awhile many of the common patterns become second nature. Dangerous Waters is one of my favorites, most of concepts in this video are modeled to some degree
I don't think its really a polar coordinate graph. It's a "Waterfall" where current bearing is at the top and past bearings are lower and lower down the screen representing time. We use this type of display in HAM radio to show activity on specific frequencies over time. Thankfully our "bearings" (actually the specific frequency in use) is constant so all of our lines are straight. Those curved lines must be insane to memorize. Also, the Navy maintains (within each and every ships sonar computers) the acoustic signatures of vessels to the point that they can even identify individual vessels of a type in many (all or most???) cases. Amazing stuff.
@@brucepreston3927 Yeah, that one got me aswell, with most basic functions used in chemistry or physics i also have a limited skill to visualise the shape of curve by looking at the formula and say whether we have some relevant min/max or limit, but this thing was AWSOME!
When I was stationed on the USNS Guantanamo Bay, Cuba we used to drop a sonar down to 11000' giving us the different temperatures in the water. We had a sonar set on the bottom of the Caribbean that we could set to test ships' sonar operator on that particular piece of equipment for a period of 8 hours. In other words, no swapping out operators because they don't all work the same way. These tests went on for up to 3 days so we could test all sonar operators. Also, our shore-based operators would give bearing and range to a target in degrees, minutes, and seconds for a very accurate reading and the had to be within 5' of a target attached to the jackstaff on the bow of the ship (a DDE). There was one time when the ship had to turn so that it would not encroach into Cuban waters, as the target was disappearing I let CIC know I was losing the target but could see the light on the top of that jackstaff. I was told after the test was done the guys on the ship laughed at my response until the shore-based station told them that I was 1/2" off of the center of the target. That shut them up, and I said I could see the light again then read my reading and they were told I was dead on the target. Someone in CIC learned a fast lesson that day.
As a STS...that book is our bread and butter. You won’t make it to E-5 without knowing that manual. But props to him for remembering what it said. Many forget after a few years.
That's his job. The RP33 is to be memorized, word for word, by ANY sonar operator, technician, or supervisor. If the Chief isn't the subject matter expert on that, he's not doing his job.
"what" is classified is as important as to "how" and "why" it is classified, so you'll find that you can have conversations with spooks about data, networking, weapons platforms, etc. The best spooks are the ones who can hold entire conversations with you without letting on about what they're withholding. It has been fun watching these guys squirm because you're literally standing inside "what" they're supposed to avoid talking about asking them "how" and "why" it works. Great stuff, Destin!
How right you are. I was part of a conversation at a wake for an uncle who none of us really knew what he did 9-to-5. Much later, news broke of the U.S. raid on Granada. I was sure it was old news, or deja vu. Then I remembered the conversation. It was a "Well I'll be damned" moment. The news just filled-in in the gaps. It was an odd feeling. Those guys were good.
I just discovered this channel and I couldn’t stop watching video after video! As a mechanical engineer in Mexico I have had the opportunity of working in aerospace and automotive, but watching these series is one step way above and they are a really good learning tool for me as well really entertaining…love this channel! Greetings from Mexico!
I hated math in high school and went on to be near the top of class. my Navy Avionics School. My last job before retirement was working a big gateway satellite earth station.
I always hated the cliche saying, "this type of math is dumb, I'll never use it". It's always from someone struggling to improve their career and can't figure out why they're going nowhere fast.
I agree. It felt short and I didn't skip anything! I normally hate the sponsor thing, but I know Dustin has to make cash some how, and I can't join patreon because I can't afford to.
You know the saying, "You can do anything you put your mind to." Well Destin you are the living representation of that in my eyes. From those home videos of you as a boy, trying to catch chickens in the yard. To an incredible understanding of some of the most complex technological breakthroughs man has ever made. You're inspiring and just a dang good guy. If I ever had the opportunity to shake your hand, man it wouldn't go for granted! Keep up the awesome work!!
And another friend is there to help keep that info a secret. Like dude, I wanna know, here have a shot and let's talk deep shadow zone mathematics with me, here, have a napkin and a pencil.
A lot of times when a submarine is told they are gonna have a “rider” they aren’t given much info ahead of time so unless they watched his channel before he got on board they probably have no idea who he is or his background or education level
@@betnav1288 I'm sure the officer's are given more information then the rest of the crew. Also through word of mouth from someone who knew his channel may of spoken up. That being said, it probably took awhile for Destin to be allowed to board that particular Submarine so the officers had time. I know not everyone knows about him and his channel but the, I forget the number, 10 Officers(?), maybe one knew. Unsure as I know it wasn't at full capacity at the time. I'm sure they had a discussion of who I am and what I do sort of thing with the officers when he boarded, off camera.
@@Degenerecy they probably had a quick brief about who he is but probably not with the chiefs (the guy who said that was the sonar chief). I was on submarines. When they had a film crew come film our submarine for a 4 part special series they just told us there would be a film crew try to stay out of there way.
I found your videos in this series by accident and have thoroughly enjoyed them. Submarine service in the Navy is somewhat shrouded in secrecy and story. You helped bring to light the day to day life aboard one. I am impressed at how tight conditions are aboard the ship; it would take some getting used to. Thank you!
I worked for the military as a computer scientist and I would hear the funny 'if I told ya I would have to kill ya' line a lot as questions I had were classified. I even asked a team working on a nuclear sub for Britain if they could accidentally launch a missle and they just said 'I hope not'
I live 30 miles-ish from where Nucular (misspelled deliberately) subs are built. It's one of the major employers in one of the larger towns in the area. A large percentage of people working there are paid to do very little work (experts at looking busy) which is fortunate because the education system in the area isn't too brilliant. I'm not saying Barrow is full of Homer Simpsons, but that'd only be a mild exaggeration. Instead they tend to get in specialist contractors in to do the hard work. Luckily the contractors aren't local and probably do the job right... So what I'm getting at is they PROBABLY couldn't accidentally launch a nuke.
@@OlanKenny I don't know if this is totally accurate. My dad is 2nd in charge at the sites that maintain and house nuclear submarines for Britain and he had to fire a very competent scientist simply because the guy walked into a testing facility with some static charge on his gloves. It sounds harsh but he said that there has to be absolutely no margin for error.
Such an amazing series, I can't believe the NAVY let him do that, and actually allowed him to share so much with all of us. Sometimes it's better and safer for most people not to know.
The stuff they allowed to be shared is public knowledge. We know, they know so to say. The stuff they don’t want to share didn’t make it onto this video. As was said on the video with the manual review “you can find this on Google”
I’m so mind blown by the level of understanding I’m capable of with Destin as a teacher... absolutely incredible man. I’m blown away by your channel every single time.
You catch on to stuff so quickly. It’s honestly really impressive. I fly on the P-8 and I’d love to fly with you and see how you wrap your mind around what we do. I recommend looking it up (if you aren’t already aware)
I still don't understand why they did away with the MAD boom on the P3 when moving to the P8 I remember at the beginning of the pandemic a RAAF P8 spent over an hour doing circuits over our city at low level late one night when there were no other aircraft flying. It was totally blacked out, but when it flew over my home there was one tiny downwards facing light, very weird. Often wondered what sort of data they were collecting?
@@chartphred1 The RAAF were probably in a holding pattern. The light was most likely a red light that is just an indicator that the plane's engines are on :) As for the MAD, the Navy decided that they didn't want it
The interesting thing about this is that most of the classified stuff (For civilians.) is likely things already known by most foreign military personnel. It all works the same way regardless of country. The advancement is what matters.
Well this is classified so a new player on the block cant make good subs. I watch a lot of Jive turkeys sub content and with that and a engineer i could probably design a ww2 sub including SOPs. However, classification on more advanced stuff means that the best sub i can build is still a noisy honking mess. This is what limits north korea and until recently iran from deploying dank subs like sweden
@@eriksunden4704 Sounds like you have been following Australia's Collins class submarines. They were supposed to be advanced non-nuclear submarines, but we're anything but. Even the engines need to to be cut out of the hull to quieten down the propulsion system. And the list of defects grew and grew. Not publicly known if they fixed the design flaws or not.. secrets, smoke, and mirrors.
i am thinking the parts they had to keep secret are the type, quantity, and placement of hydraphonnes on the sub. (among other things) i am guessing the sub also using tethered forward and aft and remote controlled or programmed mini subs that can listen and also generate sound. and perhaps now may even have AI built in and can be deployed in clusters to monitor, and collect data.. used to confuse an enemy... or confuse or create a shield to the sub?
I love watching Destin's beautifully inquisitive mind skirting around what he actually wants to ask, and making military leaders ask each other if they can actually answer it
Exactly at 6:30 the guy made it pretty obvious the answer was yes. He was stuck between not lieing and not release classified info. The question wasn't removed from the video. So the guy probably cause have gave the answer. since he did unintentionally anyway.
@@fukkitful I didn’t see it like that. It could have been no, and either way he would not have been lying if he said, “We can’t answer that because it’s classified.”
Frankly it shouldn't be classified that they use multiple frequencies to detect what something sounds like. When we use words to talk, we use different pitches, we use overtones to make different sounds. it isn't just the volume and duration of a sound which differentiates syllable sounds. Same thing with differentiating a whale from a boat.
I m sorry but I cant stop commenting on how fantastic this particular vid is. The part where Justin managed to grab the concept of "Bearing Rate" is just something (as the sonar chief commented, literally!)! He managed to get them right on the stop while I only get them after the simplified info-graphic by Justin - and I am an engineer, thou language may play it parts (English being my 3rd language). Still, its impressive dear Justin of SmarterEveryday and I m enjoying your every vid (well almost), again thank you.
I'm a Mathematics Grad, this brought me so much joy of lightbulb moments almost in time with you working this out as its explained. This is my favourite of the Submarine Deep Dive Series by far!
This also got me wondered how "a picture" painted in an animal (or human, blinded) that relies on acoustically "to see" the world around them as what being visually painted in our mind from visual stimulus by the eyes! In the end, there's whole different world being seen by others although we're "looking" at the same thing at the same time! Whew, hopefully I got that last part right (as I hopes the others "sees" as my thought). Thank you for the vid n learning, this opened not only technological knowledge but also a whole lots of philosophical meaning n answers to me.

hi there
Those people are such a great sports. Really admire them.
Do you know how many more videos in this series there will be?
Sup
I can imagine. These types of videos are always being combed for info. Same with most media😂
I love how he's like "no no, this is in this and so document, its declassified. I can get the manual if you want" You can tell how much he loves his job and loves to talk about it :)
And is not allowed to :(
I knoow :/
I am a Navy vet and I will tell you one thing that is true about every sailor, we love proving our superiors wrong. I used to walk around with multiple policies in my pocket because there are "old" policies that higher ups still think are enforced and they have been changed or they simply don't know about.
for example: I was a sailor who was sent to Iraq to help support Army operations, we wore Army uniforms, Army uniforms have some different standards for wear than Navy uniforms. Instead of issuing a whole new set of regulations for the uniforms the Navy simply issued a policy to basically state "The Navy members who wear Army uniforms will follow the Army rules for wearing said uniforms". My favorite was for backpacks, in the Navy the backpack had to be black or dark blue and could only be worn slung over one shoulder or carried. You could not wear a laptop bag slung over a shoulder or across the chest it had to be carried. The Army on the other hand didn't care how you wore the backpack as long as it was black and left your right hand free (for saluting) and laptop bags were authorized to be worn accordingly and had to be black.
When I got back from Iraq I still had to wear my Army ACU's because they told us to leave all our other uniforms at home. I was waiting to transfer to my next command and the amount of times I had to whip out the regs because some Chief or Officer would stop to scold me for wearing my laptop bag was unreal. The satisfaction I got watching many a blood vessel bulge in some chiefs foreheads was immeasurable though. most were cool and were like "oh cool, lemme write this down so I can tell the other chiefs"
scttydsntknw and this is why the comment section over here rules. Thanks for that cool anecdote.
@@scttydsntknw Right hand free just for salutes or free also for your service weapon?
"No its not, I can show you the manual where its declassified." The sign of a professional that takes their job seriously. Good for him and the guy supervising him. If a supervisor is willing to be challenged without taking it personally everyone achieves more.
Absolutely correct. I'm not on their level but I love it when my soldiers are able to tell me I'm wrong. It doesn't hurt me, it informs me and tells me that they're trying to be better than me which keeps me on my toes.
There is Stuff - fairly common everyday Stuff, not this "Cold War-Spy-Stuff" rather than f. E. the Time Plan for the Mess Hall - that is classified.
And, there is also Stuff, you are not even allowed to answer in any Way - so also not denying it.
It is often People say something Stupid just to avoid any further Questions and even "keeping silent" would be too much of an indicator.
Knowing this, mainly all you can find on YT and such is outdated (WW1-Trechtactics), common knowledge ("THAT WAY ROUND you have to hold the Rifle. THAT WAY!") or common Sense ("All the Guys around you wear blue. Your Arm you see on Screen seems to wear Blue. So guess what you gotta do with the Red ones and what not to do with the blue ones?").
In that case, the Conversation went pretty fast into "How to find out and seperate Contacts" - which is highly classified - and so the Guy showed his CO "'s all right, I know how to handle this" and just went over to the Basics, away from the deep questions. Also, that Way he provided all Answers and everybody knew that any further Questions go into the "No-Go-Zone".
I am more impressed of his Leadershipskills which I had not expected from this Guy.
yes, 100%
Please go and tell that to my boss
@@JRSLover411 This is valid in any boss role, a good boss can handle being challenged and you want employees that are as good or better in they specialty, your job is to get them to be their best, not to best them :)

destin in such an underrated interviewer. the amount of stress there is in such a interview in which a lot of the questions he’s asking can’t be answered without leaking classified information is amazing and the way he handles himself and asks all these great questions in such a situation is even more amazing. great job man.
And he's very good at asking technical questions in a way that's easy to understand
also, if i remember correctly, he has worked on military projects which are definitely classified. so he understands the background behind these things.
Pretty sure they pre-briefed him on what he could and couldn’t talk about. I don’t think they would have let a RUclipsr with a camera aboard an active nuclear submarine without laying down some ground rules before he showed up. He only makes note of it so the audience can keep up.
Destin possesses a natural (I presume) gift/skill of making those around him relax. And when we relax we can tend to let down our guard.
nah. completely over stated. everything destin asked is public knowledge. the only things clasified would be actual boat capability. all the concepts are the same. its the detail that the boat can get thats class.

I worked in the radio room, the electronic surveillance room, and the control room testing EMI levels on all types of systems on the subs. I got to see how the sonar worked, while sitting alongside the ship’s crew. Being in the control room was INSANE! I even went on sea trials with these guys, ate & slept with them for a whole week. It is definitely an experience that I’ll remember forever. Talking with the crew members about their lives and getting to know them like everyday people was an even better experience.

Sonar supervisor on a sub is the best job in the world. Nothing compares to it.
That "unwrapping" of the polar coordinate graph was an absolutely ingenious way to get people onboard who may have never been exposed to polar coordinates before. I absolutely love this channels educational animations. Destin is just one of those people who could explain any topic to you in a way you can understand and feel like you've learned something, and the constant high quality visuals just make literally anything the man talks about interesting.

The best part was how disinterested he seemed until it was obvious you were understanding and genuinely interested in what he was saying. He opened up, smiled more, and became very passionate as he spoke. I see this is so many engineers, and especially Destin in every video.
An introverted life. Dull, bland and quiet... UNTIL you get them talking about their passion. We become animated, excited & completely different people. Want to see a reclusive person do a happy dance in public? Be like Destin in this video: listen, engage & deep dive in the subject matter.
He's used to mainpy talking to people who don't have the familiarity with mathematics to easily pick up the concepts being explained

@@funkmonsterjones4753 it's more effective at recruiting or getting kids interested in science/engineering/math which is ultimately Destin's goal. This isn't much of a show of force video. They use videos of missile launch tests and war games for stuff like that, not simple explanations of stuff that literally every sea-faring nation on Earth has known for decades.
@@funkmonsterjones4753 No one who is even midly interested in military power would be surprised by anything that is said/shown in this video. The USA has nuclear submarines in the Artic? Who would have thought about it, right?
@@tinchote It's the fact that this stuff is for civilian consumption. The military is usually twenty years ahead of whatever is declassified, so this video sets the bar. If Iran or NK are 10 years ahead of this, they can estimate that they are 10 years behind us.
It's also scary for them to know how many American civilians actively educate themselves about military hardware and tactics, and that those people form communities who share intelligence with each other. Propagation of information is one of our strong suits. Especially among teenagers. That suggests a future where young Americans are more ready for war than our adversaries.
All of these ideas add up to a great deterrent. Funk is right. Dustin himself realized his video on the Future of Warfare was a weapon in the cyber domain, just one of the domains of modern wars, and it's the one the military needs civilian help to operate in.
Hahahahahahahah
I love how Garrett just started nerding out with Destin. Even pushing back on the executive officer about classified status to go into more detail with him
That's one thing I loved about being in the Navy. The best officers were not afraid to admit when they were wrong, and encouraged the senior enlisted and other officers to firmly, but politely, challenge them, like how the Chief challenged the XO.
I loved the "I'll show you the manual" part. Sounds like the type of stuff I say all of the time and people just call me an @$$. "No, really, just listen--I'm right."
"It's unclassified, it's in an unclassified manual, I'll run over and grab it for you right now."

Why are you jalapinhisbusiness?
as a sonar op myself, you did an amazing job at explaining something very complicated in a simple way, wait until you learn about passive narrowband and doppler effect!
He already knows that stuff. They just couldn't talk about it here.
i love doppler effect. whenever i experience it I just perk up and I'm like "there's physics in action" Ambulances and music turning eerie and slow are my favorites
@@foobarmaximus3506 we all already know about the Doppler effect, we just didn't think about it and how it is used in combination with all the confounding factors like lensing, multipath, etc.
Simple radar/sonar is simple. Send a ping wait for response for ranging, listen using a phased array antenna for direction.
But once you add in one or two or five confounding physics phenomena, rotating reference frames, the Doppler and lensing, etc, this stuff gets real hard to visualize real quick, and you need some signal processing to help you out.
I was hoping they would get into the towed arrays and other things related to that subject. But I’m sure not much of that would make it into the video. I’m surprised they let that much on passive sonar make it into the video. Everyone thinks about pinging sonar when they hear the term sonar. Not sure if the SOSUS will be able to get much attention in this series.
Is it ALL sound based or are there electromagnetic (I guess it would be radar) options too? Obviously under water the frequency bands used would need to be different, but is there any EM based stuff like that on subs?

This is one of those channels that makes the internet so valuable. Through Destin and his learning/teaching journey, he allows us to meet people and experience things that in no other way would the average person be able to do. Climbing aboard a US nuclear sub?

Wow thats an awesome detail
I am a former sonarman on an Arleigh Burke class destroyer, and I must say that this is a very good video when it comes to explaining what I used to do in the Navy as an STG 2 Sonar Supervisor. Yes, lots of math and knowing the "signature" of every single ship and sub that exists (or at least those that we know of), plus all of the biologics and underwater topography (and oceanography).
It does take a lot of mental aptitude to first identify the contact that you're hearing (you need to know the specific frequencies that every vessel emits into the water), and then you need to do the trig to actually figure out where it is in the water (i.e. time and space), and what direction it is moving (and at what relative velocity). And you must do this using only heard frequencies in the water, while also allowing for real-time changes on our part or theirs.
We generally had 3-5 minutes to first identify the contact, and then another 5 minutes to determine where it is (and what speed/heading it was on). By the time that I left the Navy, the buttons on my calculator were worn entirely unreadable (and I bought it brand new when I checked aboard my ship). I did two deployments to the Gulf, plus an INSURV. My ship came in second for the Bloodhound Award after INSURV.
Here's a question for you: how much does having a discerning ear come in handy as opposed to math skills? Is it more important to pick up the subtleties in sounds or to be able to crunch through a bunch of raw data?
@@margotrosendorn6371I can’t speak for submarines, because I’ve never worked on one. On a destroyer however, you will rarely have to listen to the information you are receiving. The important parts of the data you need to process and identify will be in front of you on your monitor.
My fellow STGs and I got a chance to go check out combat systems and sonar on the Arleigh Burke and we were so dejected when we got back to our sonar suite on our frigate.
@@margotrosendorn6371It's all about data. You can't do it without the math. You have formulas and equations to apply to every frequency in hertz to again apply to various equipment, blade rates, types of propeller blades, number of blades, auxiliary equipment, speed, etc that would be impossible otherwise. You crunch the numbers and check your frequencies to determine exactly What type of contact you have. Actual "hearing" doesn't even come into it.
I'm starting to get a better appreciation for how busy Destin was when he was on the submarine for 24 hours. Fire drills, pizza night, sonar diagrams, getting stuffed in a torpedo tube, and I can't wait for [REDACTED].

“I’m impressed how fast you got the bearing rate thing”

Because you're not learning. People watch these videos on RUclips and then think they're super confident about whatever it is--that they now can do or understand the thing. But studies have shown that after about 24 hours to 1 week, you've learned nothing. Further, we tend to overestimate our ability to understand or do things when we watch other people do them in videos. "Oh I can do that--it's simple now that I know how".

I like chief's deadpan response to XO where he's like " I can go get it if you want..." haha. The content you are able to deliver on this channel is really amazing.
Dustin, I am a 73 year old female who appreciates you being such a great educator. So happy I found your site.
Destin: “So do you guys-“
XO: “That’s a no-go.”
Destin: "so i went on Google and found this"
@@Sorent1993 I remember when I was briefed on classifications they said “even if it’s unclassified and you can find it on Google, don’t tell them they can find it on Google.” Lol.
Pretty sure that was "--monitor passive RADAR??"
@@Willaev If it's unclassified, it's unclassified and can be released to individuals without a clearance. If it's classified even if you can find it online, you do not confirm that the information is correct or tell people where they can find it.
@@melodyqueen6432 ...or one a few dozen other things we do on subs. Cheers.
Destin, I just wanted to thank you for making this video. My grandpa was a Commander in the US Navy and was heavily involved in testing sonar under the ice caps after WWII and into the Cold War. I was always so curious about what he worked on that was so top secret he could never tell us what he did. All we knew was that it must have been important because in 1999, on a bike tour around the world, he opted out of the portion in Russia because he feared there would still be people after his research. He passed away several years ago, but this video has brought me closer to understanding what my grandpa worked on. So thank you for teaching me more about my family!
P.S. One story he could tell us was about when he was being chased by a polar bear while carrying 50lbs of sonar equipment. He went back the next day to measure his footsteps and each one was between 12-15 feet apart!
I think he discovered a new training plan for Olympic track and field athletes. Forget about training at high altitudes to build lung capacity! Just keep out running the polar bear! Whoever's left makes the team.
My grandad was a civilian contractor for the Navy, with Westinghouse-the company that made the Navy’s nuclear reactors. My grandad’s specialty was metallurgical engineering, specifically, how the structure of metal alloys changes under the intense nuclear radiation found inside a reactor, and how to detect those changes. So he actually helped to design the reactor vessel on the USS Nautilus...something we didn’t learn until many years later, once that reactor design had become obsolete.
@@lmamakos You don't need to outrun the polar bear, you just need to outrun the other guy.
I'm amazed he could outrun a polar bear, the things are suprisingly fast and highly aggressive in the wild.
One way you can potentially solve the multi-return issue is using what's called a band-pass filter. If you know what the object you are hunting is made of, you can anticipate the frequencies that will have the highest energy on return. Steel will return different dominant frequencies than say ice or mud. You can frequency filter your return data to give you the true target.
I imagine if you have a passive cue you can at least filter out the active returns that arent in a similar azimuth/elevation as as the passive cue. But still, the passive cue has it's own multipath problems. Its like, if you know where it is, you know where to look, but if you know where it is you dont need to look. Hmm. Im sure there are fancy computers that take all these things into account and fuse the data from multiple sensors and narrow down the error possibilities automatically.
Neat stuff.

That guy was not a supervisor. He is an Officer and it is just a 2nd set of eyes to make sure it didnt go off into something that could expose classified info. Just worked as a backup.
@@Torpedomtb At first I thought the executive officer being there was pointless. The Navy was going to sanitize all his data, but that wouldn't help if he learned something with the camera off. I'm surprised he wasn't just given a list of questions that were okay to ask.
@@fukkitful Yea it was pointless, the sonar sup is the highest expert on the topic on the ship. XO is like middle management, so he had to be there even knowing he doesn't know the topic. I do wish he gave more info as he was still far away from the line on many aspects, but seems the sonar sup was too scared to do that (don't blame him) since even public info can be class'd and while you can google it if he talks about it he'd be in jail.
they all seem drained. I guess living in a submarine would do that to you
as a former sonar tech on subs, I found this HUGELY helpful. Now I just send it to everyone who asks what I did! and remember, the XO is everywhere...

So cool Dave! Love it!
wish I had this video when I was learning
so dave no body talk about sonar SIZE LIMIT !! i mean contact size limit.. like no body. does this classified ?? can sonar detect small things like 10 cm fish ?
@@moustafarefaat6155 remember, he's discussing passive sonar, so the 'brightness' of his contact isn't based on size, but sound level. So, in dog units, a chihuahua-fish would be much brighter than Labrador-fish on the screen because of their sound output. There are some stunningly noise little critters in the water for their size.
I love his "Nice" after you had to cut your question out. I'm in love with this series because your walking the line of classified.
Fascinating watching this as a sonar technician in the navy. Most of the things they discuss are the basics and I can infer the things the chief can’t talk about but it’s cool seeing a civilian trying to decipher and create a picture on how we operate.
You could actually see the dude's brain working, thinking "how can i say this in both simple terms and not give away state secrets" lol
I worked for the government and used to have to do this to explain why I was working late or if someone asked me what I did.
Like the DoD version of the startup tech guys Destin interviewed a couple years ago with the VR gloves.
Seriously. The mental calculus Destin made this guy do was insane.
1) Can I answer that?
2) Can I answer it in a way Destin (and his audience) will be able to understand it?

Yes, for about the first three quarters of it, then got lost.
Yes, after wrapping my head around spherical harmonics this was a walk in the park in comparison :/ (I hate that I love physics)
I made a reading. What I did not account for was that the sub was also changing heading. Thats one crazy geometry problem.
Sort of
The bearing rate graph was a mind bending realization for me. Especially when the sub started to rotate 360° and the surrounding craft were plotted around it. I now have an immense respect for these submariners.

Trust that the officers have in their men, and the fact the men don't fear their officers is a great thing.
@@SVSky So true
As a submariner, you did a great job on this video. The bearing over time visual was a great product that gives people a way to see what we see on board. Also great job explaining how sound works. There's so much that goes into it but you did a great job. Bravo Zulu 👏👏👏
Why are so much stuff classified, like what is the Navy trying to protect? Can one not just find "classified" info on the internet?
@@dean3188 Operational and national safety obviously. If the methods and functions of equipment were to be leaked, it could lead to exploitable vulnerabilities.
You also have to account for the unforeseable. Someone might exploit information that seems harmless. So keeping a tight lid and some obscurity around information is adding a layer of safety.

The polar coordinate graph and reading everything's position while moving has got to be the coolest skill I've ever seen!
I can't imagine the amount of training it takes to be able to do that under stress!
@@brucepreston3927 It certainly takes practice, but there are plenty of sub simulators out there that use bearing rate graphs. I don't claim to be an expert, but after awhile many of the common patterns become second nature. Dangerous Waters is one of my favorites, most of concepts in this video are modeled to some degree
I don't think its really a polar coordinate graph. It's a "Waterfall" where current bearing is at the top and past bearings are lower and lower down the screen representing time. We use this type of display in HAM radio to show activity on specific frequencies over time. Thankfully our "bearings" (actually the specific frequency in use) is constant so all of our lines are straight. Those curved lines must be insane to memorize.
Also, the Navy maintains (within each and every ships sonar computers) the acoustic signatures of vessels to the point that they can even identify individual vessels of a type in many (all or most???) cases.
Amazing stuff.
i guess i can figure out lil bit what air traffic deal with everday
@@brucepreston3927 Yeah, that one got me aswell, with most basic functions used in chemistry or physics i also have a limited skill to visualise the shape of curve by looking at the formula and say whether we have some relevant min/max or limit, but this thing was AWSOME!
When I was stationed on the USNS Guantanamo Bay, Cuba we used to drop a sonar down to 11000' giving us the different temperatures in the water. We had a sonar set on the bottom of the Caribbean that we could set to test ships' sonar operator on that particular piece of equipment for a period of 8 hours. In other words, no swapping out operators because they don't all work the same way. These tests went on for up to 3 days so we could test all sonar operators. Also, our shore-based operators would give bearing and range to a target in degrees, minutes, and seconds for a very accurate reading and the had to be within 5' of a target attached to the jackstaff on the bow of the ship (a DDE).
There was one time when the ship had to turn so that it would not encroach into Cuban waters, as the target was disappearing I let CIC know I was losing the target but could see the light on the top of that jackstaff. I was told after the test was done the guys on the ship laughed at my response until the shore-based station told them that I was 1/2" off of the center of the target. That shut them up, and I said I could see the light again then read my reading and they were told I was dead on the target. Someone in CIC learned a fast lesson that day.
Start your own channel maybe? lol
You probably just leaked classified information 😬
Gotta love the chief, literally knows the handbook from the back of his head.

As a STS...that book is our bread and butter. You won’t make it to E-5 without knowing that manual. But props to him for remembering what it said. Many forget after a few years.
That's his job. The RP33 is to be memorized, word for word, by ANY sonar operator, technician, or supervisor. If the Chief isn't the subject matter expert on that, he's not doing his job.
@@jarvisruddy4611 Well do you know the back of your hand?
Full credit to the US Navy for letting this episode come to pass. Much appreciated.
"what" is classified is as important as to "how" and "why" it is classified, so you'll find that you can have conversations with spooks about data, networking, weapons platforms, etc. The best spooks are the ones who can hold entire conversations with you without letting on about what they're withholding. It has been fun watching these guys squirm because you're literally standing inside "what" they're supposed to avoid talking about asking them "how" and "why" it works. Great stuff, Destin!
How right you are. I was part of a conversation at a wake for an uncle who none of us really knew what he did 9-to-5. Much later, news broke of the U.S. raid on Granada. I was sure it was old news, or deja vu. Then I remembered the conversation. It was a "Well I'll be damned" moment. The news just filled-in in the gaps. It was an odd feeling. Those guys were good.

@@betnav1288 I'm sure the officer's are given more information then the rest of the crew. Also through word of mouth from someone who knew his channel may of spoken up. That being said, it probably took awhile for Destin to be allowed to board that particular Submarine so the officers had time. I know not everyone knows about him and his channel but the, I forget the number, 10 Officers(?), maybe one knew. Unsure as I know it wasn't at full capacity at the time.
I'm sure they had a discussion of who I am and what I do sort of thing with the officers when he boarded, off camera.
@@Degenerecy they probably had a quick brief about who he is but probably not with the chiefs (the guy who said that was the sonar chief). I was on submarines. When they had a film crew come film our submarine for a 4 part special series they just told us there would be a film crew try to stay out of there way.
If just one person on that boat knew who Destin is they all knew. Scuttlebutt travels faster than light.
Well said.
Thank you to Executive Officer Andrews for being patient with this. Those two seemed really excited to talk about this topic.
I found your videos in this series by accident and have thoroughly enjoyed them. Submarine service in the Navy is somewhat shrouded in secrecy and story. You helped bring to light the day to day life aboard one. I am impressed at how tight conditions are aboard the ship; it would take some getting used to. Thank you!
I worked for the military as a computer scientist and I would hear the funny 'if I told ya I would have to kill ya' line a lot as questions I had were classified.
I even asked a team working on a nuclear sub for Britain if they could accidentally launch a missle and they just said 'I hope not'
I live 30 miles-ish from where Nucular (misspelled deliberately) subs are built. It's one of the major employers in one of the larger towns in the area.
A large percentage of people working there are paid to do very little work (experts at looking busy) which is fortunate because the education system in the area isn't too brilliant. I'm not saying Barrow is full of Homer Simpsons, but that'd only be a mild exaggeration. Instead they tend to get in specialist contractors in to do the hard work. Luckily the contractors aren't local and probably do the job right... So what I'm getting at is they PROBABLY couldn't accidentally launch a nuke.
@@OlanKenny I don't know if this is totally accurate. My dad is 2nd in charge at the sites that maintain and house nuclear submarines for Britain and he had to fire a very competent scientist simply because the guy walked into a testing facility with some static charge on his gloves.

I've been a subscriber of SED for years, and Destin already has interviewed a President...Obama 4 years ago.
Such an amazing series, I can't believe the NAVY let him do that, and actually allowed him to share so much with all of us. Sometimes it's better and safer for most people not to know.
The stuff they allowed to be shared is public knowledge. We know, they know so to say. The stuff they don’t want to share didn’t make it onto this video. As was said on the video with the manual review “you can find this on Google”
To be fair, this sort of stuff also acts as a sort of psychological/cyber warfare as well.

You catch on to stuff so quickly. It’s honestly really impressive. I fly on the P-8 and I’d love to fly with you and see how you wrap your mind around what we do. I recommend looking it up (if you aren’t already aware)
actually I was wondering how radars work looking downwards into the ocean!
I still don't understand why they did away with the MAD boom on the P3 when moving to the P8
I remember at the beginning of the pandemic a RAAF P8 spent over an hour doing circuits over our city at low level late one night when there were no other aircraft flying. It was totally blacked out, but when it flew over my home there was one tiny downwards facing light, very weird. Often wondered what sort of data they were collecting?
@@clutchsharp2343 they don’t penetrate the water, just the surface
@@chartphred1 The RAAF were probably in a holding pattern. The light was most likely a red light that is just an indicator that the plane's engines are on :) As for the MAD, the Navy decided that they didn't want it
The interesting thing about this is that most of the classified stuff (For civilians.) is likely things already known by most foreign military personnel. It all works the same way regardless of country. The advancement is what matters.
Plus most countries that have subs have knowledge sharing with the US because of alliances
Well this is classified so a new player on the block cant make good subs. I watch a lot of Jive turkeys sub content and with that and a engineer i could probably design a ww2 sub including SOPs. However, classification on more advanced stuff means that the best sub i can build is still a noisy honking mess. This is what limits north korea and until recently iran from deploying dank subs like sweden
@@eriksunden4704 Sounds like you have been following Australia's Collins class submarines. They were supposed to be advanced non-nuclear submarines, but we're anything but. Even the engines need to to be cut out of the hull to quieten down the propulsion system. And the list of defects grew and grew. Not publicly known if they fixed the design flaws or not.. secrets, smoke, and mirrors.
i am thinking the parts they had to keep secret are the type, quantity, and placement of hydraphonnes on the sub. (among other things) i am guessing the sub also using tethered forward and aft and remote controlled or programmed mini subs that can listen and also generate sound. and perhaps now may even have AI built in and can be deployed in clusters to monitor, and collect data.. used to confuse an enemy... or confuse or create a shield to the sub?

Exactly at 6:30 the guy made it pretty obvious the answer was yes. He was stuck between not lieing and not release classified info.
The question wasn't removed from the video. So the guy probably cause have gave the answer. since he did unintentionally anyway.
@@fukkitful I didn’t see it like that. It could have been no, and either way he would not have been lying if he said, “We can’t answer that because it’s classified.”
Frankly it shouldn't be classified that they use multiple frequencies to detect what something sounds like.
When we use words to talk, we use different pitches, we use overtones to make different sounds. it isn't just the volume and duration of a sound which differentiates syllable sounds. Same thing with differentiating a whale from a boat.

Hi
As a random guy reading your comment I have absolutely no opinion in response.
I flipping LOVE when Destin’s enthusiasm catches on to his interviewee. This was one of the best SED I’ve ever watched. Well-done!
I m sorry but I cant stop commenting on how fantastic this particular vid is. The part where Justin managed to grab the concept of "Bearing Rate" is just something (as the sonar chief commented, literally!)! He managed to get them right on the stop while I only get them after the simplified info-graphic by Justin - and I am an engineer, thou language may play it parts (English being my 3rd language). Still, its impressive dear Justin of SmarterEveryday and I m enjoying your every vid (well almost), again thank you.
I don't understand how this video can be so long yet so short at the same time
Sound waves and stuff.
I'm a Mathematics Grad, this brought me so much joy of lightbulb moments almost in time with you working this out as its explained. This is my favourite of the Submarine Deep Dive Series by far!
*Inserts idea about how we calculate where a ship is and how to shoot to sink her*
Maaaan. For 1 day on a sub, you were busy! I didn't think we'd get this much content from your stay. Thanks Destin.
Gotta make it count. Not like he’s going to get invited every 6 months. He doesn’t even look rushed in any of the videos, just enjoying himself.
I think he said in the first video he was staying there for a few days.
This also got me wondered how "a picture" painted in an animal (or human, blinded) that relies on acoustically "to see" the world around them as what being visually painted in our mind from visual stimulus by the eyes!
In the end, there's whole different world being seen by others although we're "looking" at the same thing at the same time!
Whew, hopefully I got that last part right (as I hopes the others "sees" as my thought). Thank you for the vid n learning, this opened not only technological knowledge but also a whole lots of philosophical meaning n answers to me.
