Gotland
Gotland SSK
I visited the Uppland in March 2016 at Karlskrona and was allowed to tour her on the condition I surrender my phone and any other electronic devices which is usual practice
I did get one cheeky snap of her though 😉
I entered through the forward hatch and dropped into the torpedo compartment and to be honest it was as I had expected quite large inside (no weapons on board)
The first thing that struck me was the layout of the torpedo tubes they are 4 over 2 also they carry two sizes of torpedo and that was the second thing I noticed
The four centre tubes are 53cm the two tubes below are 40cm and you do notice that right away as the smaller tubes are pushed forward I’ve only ever seen 40cm on older Russian boats
The XO of the boat explained the sonar system is quite large for the hull this is why the tubes are configured this was and the bomb shop is on two levels (the deck can be lifted)
the bow array is above the tubes she also has two hull arrays one each side and a small chin array
It’s pretty much a traditional layout for a boat something you would expect to see
Moving back into the living area is quite plush for a diesel boat but still small and cramped but adequate the bunks were quite comfy and the usual small space to sleep etc
The real interesting bit for me came in the control room which is below the sail it’s actually laid out quite well with the usual stations
Very heavily computerized like you expect on a western boat but there’s some analog dials and gauges and valves in the spots you would expect them to be
The layout has the stations sat on each side of the compartment back to back there’s several stations for sonar which if I recall rightly is the starboard side with fire control communications on the port side
Obviously you notice two scopes and the captains chair off to the rear was the navigation area
So for me pretty standard layout but you got the idea that this set up made for a good flow of information and this setup has been adopted in the Virginia and astute I believe
Back a bit further is another mess and galley which is usual size nothing I didn’t expect to be honest
the engine room which is almost standard one engine each side but there’s a lot of new attachments to the engines I was told this was to do with the sterling system (of course they won’t go into detail with me)
Now the mid life upgrade they put a plug in so it has changed since I went onboard
The sterling system is quite obvious to see and filled the aft engine room
Behind all this is the shaft and below is the second bank of batteries
Oddly aft there’s what the XO described as a computer room I was not allowed in here I was told it’s off limits to everyone of the crew bar certain officers and enlisted
Leaving via the forward hatch again I got the sense that this is a good boat she is actually very well maintained so she is looked after and despite her age she would give most ASW platforms a headache
She certain doesn’t show her age I had previously been on Orzel a Polish kilo class spent 3 days underway with her and the difference is night and day !
The flooring in uppland is even made of sound absorbing material and you get a sense that they built this thing to be silent first and foremost then efficiently in command and control
I saw a similar set up in the German type 212’s as well so the Swedes and Germans defiantly have had a chat about it and come to similar conclusions
The 40cm torpedo tubes can hold two 40cm torpedos at a time and the large tubes can also be loaded with several 40 cm torpedos.
@@maytrows how? So torpedoes firing without air-hydro impulse? Or with their own propulsion power. Swedish subs really the best for shallow waters, but noise level of them is much higher a hydroacoustic phone of Baltic see, so... You can think about it :)
@@Popkootn2010 The tube is flooded and the torpedoes swim out by their own, so no compressed air is used in the firing. The 40 cm torpedo at the time(Torpedo 45) is electric so no exhaust in the tube. Very quiet.
Not sure what about you mean in the latter part, bad translation?
@@maytrows ya the USN nuke subs have doubles shot for years. It's a tactic.
What a unique experience!
I toured the U.S.S Cheyenne SSN-773 at Pearl Harbor circa 1999 or 2000 during Yama Sakura exercise with Japan. A group of us service members from Wyoming were allowed on board (Cheyenne is Wyoming's capitol city). It was quite the experience! We weren't allowed in the reactor compartment.
Funny story, I saw the Gotland crew at IKEA at San Diego. They were buying Swedish foods. I mistook them for IKEA staff much my embarassment.
You shouldn't be too embarrassed when they are dressed like the store colors
@@thejohnbeck Same as the colours on my Coat of arms and the Swedish flag.. although these days we keep getting asked if we are are Ukranians! Funny thing is Sweden ran the Ukraine area back in Viking days!
Wow, that's a long trip for a small Diesel boat. Unless they came without the boat. Edit: ah, should have watched the whole Video.
I served as an engineer on Gotland in 2005 when we went to San Diego. It was a surreal experience going from the Baltic to hearing dolphins and whales on the sonar.
Hade du Richard som båtchef?
Jive, that sign saying FMV at 2:00 is not Swedish. FMV in Swedish is an abbreviation for Försvarets materielverk.
that puzzled me too. his fmv logo is in turkish basically its a school foundation which has a university and a high school in turkey not related to this magical machine sadly.
Roughly translates to Defence Materiel Works if I'm guesstimating my Swedish correctly?
@@jacquesmouton1339 yes
@@jacquesmouton1339 I think it's generally translated to "The defence materiel administration".
That's a Turkish sign
Few things: Stirling engine is NOT an internal combustion engine. It is EXTERNAL combustion engine. It means that piston is heated from outside.And helium and nitrogen are not part of the combustion process, but they are inside the piston, as a working gas.
At 18:04 it says that the upgrade of Gotland cost 2.1 Billion Sek and that is equal to $2.2B. The correct value is that 2.2 Billion Sek is about $250 M !.
Wow
Thats cheap
@@dolguldur4706 For comparison: the us military budget was about 705 bilion for this year
@@dolguldur4706 And the Gripen NG can be had for 30-35M$ a pop. And can whip an F/A-18.
It's all about thinking efficiency from the get-go. Adapt a little more to the available tech first and identify its specific advantages to build upon, rather than "lay down some requirements, see what comes out."
depends if it refers to swedish biljon or Billion . our biljon is with 12 zeroes and yours are with 9. then it would be 250 billion dollars. but i highly doubt thats the case. (just a lil fun fact)
It was HMS Halland that sparked the USNs interest in the class in the year 2000, when she won several duels in the atlantic against Spanish naval units and a French SSN. Later that year she participated in an exercise in the Mediterranean sea. The USN sent USS Houston, and from what I know, Halland won that one to.
The USS Houston has also done trials/wargames against the Collins Class in Australia. I saw it at Garden Island when I was doing consulting to the RAN.
I dance for pennies isn’t the Collins class based on this Swedish design?
@@lepanhman yes it is.
Regarding the USN, "Success is a poor teacher."
Actually, regarding anyone or any group.
@@dmikulec Well just look at France during WW2, has everything needed to prove that theory.
@@MrSigmatico lol when did the french ever do well in WW2
There is a story that is missing, what got the US to lease the Gotland in the first place. Well sometime in 2000-2001 the Halland did a tour to the Mediterranean and asked if countries wanted to train with her. Pretty much everyone along the way and the US said yes. For instance the French wanted to see if we could infiltrate their carrier group and sink their CV. The results? The French and the US navy have something in common ;)
Halland did a great in every exercise it participated in regardless of scenario and "opposing" assets. The exercise with the US was with a Los Angeles class sub, sadly our brief was running out of time so the the officer giving the brief summarized it roughly "it went as good as all the rest, lets just say the Americans had a little bit of a reality check and probably needed to make some phone calls".
Couple of years later the Gotland was leased.
Ask Jens for an interview, I bet if you ask you could work something out, the Sweedes are very accomodating like that.
I agree, you should ask him!
The fact that Aaron was a submariner too and understands the principles of OpSec probably is a bonus selling point in there.
I'd say there's a good chance he will watch this episode sooner or later.
Gotland = “goatland” , Jens = “Yens”
The company I worked for in San Diego, CA designed and developed their transient acoustic sonar system in the late 90's and early 2000. As the system engineer for the project I designed the hardware and software system, and led the development in the software system. It was a nice project for a company that had developed similar systems for the U.S. Navy like the BQR-22A and BQR-23.
While I was studying at uni I worked extra during the summer break and weekends at a battery factory.
The coolest thing I ever did at that place was and something I'm actually am proud of was to build batteries for the Gotland submarines.
When they change batteries every X years they put it in a dry dock, cut it open - replace the batteries and then weld it shut again.
The specs and quality checks for those batteries were at least 10x compared to everything else we did, and some of them had some really funky shapes.
Vilken fabrik gör batterierna?
@@eriksunden4704 Jag vet inte var de görs nu för tiden, men på den tiden så var det i Tudors batterifabrik i Nol, strax norr om Göteborg.
Fabriken la ner när miljöpartiet kom in kommunfullmäktige i Ale och miljökraven skruvades upp så högt att det varken var ekonomiskt eller praktiskt möjligt att uppfylla dem.
När jag jobbade där så filtrerades all luft och vatten som hade varit inne i lokalerna och det fanns speciella klistermattor vid alla dörrar så inget blydamm skulle följa med ut under fotsulorna.
Efter de ytterligare ökade kraven så flyttade man istället tillverkningen till Polen där kraven var mycket lägre.
2.1 billion SEK is about 244 million USD at current rates.
I suspected that seemed a bit high but I don't know a kroner from a shekel. Thanks for letting us know!
You got the speed wrong ;)
Surfaced: 11 knots (20 km/h) Submerged: 20 knots (37 km/h) on batteries; 5 knots (9.3 km/h) on AIP
Good catch;. I turned km/h to knots by mistake for the AIP.
@@SubBrief no problems :) i really like these videos. Keep up the good work and have a awesome day!
I rather suspect those numbers are as honest and accurate as the test depth. XD
@@liesdamnlies3372 FMV has a long tradition of only stating "garantied numbers" they never publish the true numbers for Opsec. It doesnt matter if its jets , submarines or small arms.
@5:54 on the propeller to the left in the drawing it says "Super secret, low-noise propeller"
OMG... I checked and you are right! Super funny.
Dude, your FMV logo there at the beginning has nothing to do with our Försvarets Materielverk. I'm not sure what it is, but the name looks like Turkish.
Correct, it's Turkish.
Yes looks like it is some sort of Turkish school
I think he nust have searched for FMW and he got that Turkish school instead of the Sweedish Defence material works
I agree. It's not the FMV logo !.
i am turkish and yes the logo is turkish says Feyziye schools foundation
Everything is so clean. From proposal process, production and even take a look at their shipyard. Just clean. Naturally I understand that those factors become a tad easier when you’re able to do small boutique style production but still it’s commendable to be so clean throughout.
And great job Jive! Once again, such a great production on your behalf as well my dood! Being on the NAVAIRSYSCOM side of the house I always recommend your content when asked where to look for good OS briefs.
The thing you don't see is that horrific wind. The trees are growing at an angle. My eyes were constantly filled with tears. You can find loose wrenches and bolts on the nearby fields.
Joking aside, a clean shop is part of the tradition.
⁶⁷⁸
Ah yes, the small submarine boutique, remember to shop local, don't buy your submarines from those big chain submarine stores.
If you think _that's_ clean and neat and botique, you should see Königsegg's facilities...
I'm sure the crew didn't mind staying in San Diego for that long.
With their accent, I am sure their Doc was handing out condoms like crazy!
For the first year they exchanged crew every 6 weeks. Could not find information about the second year.
@@jensolsson9666 Strange , from memory , they hired 2 crews. One per year basis , since our conscription period is no longer then 15 months , usually 10, at that time. I dont know how long the renewed conscription works since restart in 2014.
The U.S. Navy should build diesel-electric submarines modeled after the Gotland and use them for among other things, protecting the missile subs from possible sneak attacks as they depart and return to their lairs. I suspect if the U.S. Navy does build modern diesel subs with air independent propulsion and all the latest quieting technology, they would be larger, carry more weapons and probably would be both faster and deeper diving. Some modern diesel boats can operate at very deep depths, which makes an already stealthy submarine even more so.They are ideal for protecting our coastlines because they do not need to go far from home, and they are very cost effective ways to augment the fleet so the larger nuclear subs can do other things farther from home. I'm glad this boat was covered in a video on this channel.....it sounds like a submarine Sweden should have built more of.
I think that Australia's new Attack class submarines would be a better fit for the US Navy - if the US can license build them at a reasonable cost.
The US has had a diesel electric sub barbel class, which influenced most of today’s diesel electric subs, but gave them up. The speed, power and range of nuclear subs are way off the charts compared to conventional subs. Imagine a diesel electric sub was usain bolt. A diesel electric sub goin full speed is like Usain sprinting. But eventually after a short sprint gets tired and can’t keep up. Nuclear subs are like if Usain Bolt is running His same speed for an ultra Marathon. Also you know in real life the US actually sank carriers for real and not war games, and Japanese subs did the same to the US so it’s not like it’s some huge new thing. Barbel class diesel subs themselves sunk carriers in exercises.
Modern Nuke boats could do the same since a modern nuke boats and diesel electric are equal in terms of quietness.
@@gj1234567899999 Diesel boats are much cheaper than nuclear boats, do not require use of limited nuclear production and support facilities, are much cheaper and easier to retire at end of life, and with AIP can potentially be quieter than nuclear boats for days or weeks at a time.
The Japanese subs are the closest in design to the old US diesel subs but have gone through several generations of improvements since they took inspiration from Barbel class. The US Navy might be comfortable going with these due to the design lineage but Australian Attack class would be a better option in my opinion.
One of the advantages of building diesel boats is that they could be produced and serviced at different shipyards than the nuclear boats, thus not reducing the potential production or servicing of the nuclear boats. The US Navy does not want to lose any nuclear sub numbers but would probably not mind some modern diesel subs in addition to them.
Some diesel sub designs could potentially even be built at shipyards on the Great Lakes as long as they have dimensions capable of going through the locks. Some German diesel subs regularly go through the Kiel Canal and there is some utility to have shallow enough draft and small enough dimensions to pass through these tight and shallow areas.
Give the US Navy a dozen modern diesel subs on top of all of their nuclear subs and they could be useful in a variety of missions while relieving the nuclear boats of some of those missions.
@@stupidburp And you have to carry them over for weeks from theater to another.
Late last year the new 5 year defence plan was encted and in that the third Gotland class submarine will undergo MLU as well
The previous was called Sjöormen (Sea-Serpent)
Sjöormen class 1967-68
Näcken class 1978-79
Västergötland class 1983-90
Gotland class 1995-96
This is lovely. Although get ready for the new Blekinge class.
Great video Jive! As an update on RADM Nykvist, in February 2020 he moved from Chief of Navy to Minister of Defense, and is currently Sweden's military representative in Brussels for the EU and NATO.
He's a good man and Captain. Glad to hear he's doing well.
Jens moved to the ministry of defence, not defence minister, the defence minister is named Peter Hultqvist, but the rest is correct.
Great brief Jive, very informative. Did however experience lots of glitches in the video, which I'm sure was something to do with the RUclips platform.
Yeah, was thinking that was on my end, glad I was not the only one :D
Hello there, a pedantic swede here.
About ÅÄÖ and how to pronounce them:
Å soundes like the O in More, Gore, Lore, Door, For, Store
Ä sounds like the A in Damn, Van, Land, Man, Band
Ö sounds like the U in Murder, burn, turn, the E in Stern, the EA in Learn

The stirling engine idea is pretty cool. I really like the fuel cell AIPs. Take hydrogen, combine with oxygen, get energy and pure water.
You can store the pure water and once you surface you can use power derived from the diesel engines to reclaim almost all of your hydrogen and oxygen stores! (albeit pretty inefficiently)
And it's way better than just dumping the pure water (since you can't drink it anyway), because electrolysis of saltwater tends to leave a lot of crap behind lol
You can drink distilled water just fine. The amount needed to cause osmotic shock would even cause that if the same amount of tap water had been drunk. Distilled water being toxic is a pretty old yet very stubborn myth. The same goes for heavy water, which is harmless as well.
Waiting for A26 model to review.
There were several Swedish submarine classes between the Sjööormen and Gotland. The Näcken and Västergötland class are two of them.
What a capable submarine & crew. Hats off to the little David slaying the Goliath....luckily for all of us in an exercise.
Small correction. Jens Nykvist is as of last year no longer chief of the Swedish navy. He was replaced after long and faithful service by Ewa Skoog Haslum. Perfect video otherwise. Really enjoyed it!
Yeah - perfect except for getting the cost of the MLU upgrade wrong by a factor of 10 & inverting the surface vs. Underwater speed.
He advanced the ranks rather than being replaced :-)
Those pictures at 6:48 are from 2015 and show the first steel cut for the new Blekinge class (A26).
Been waiting for this. Fun too se my country build something good :)
Thank you. This is the video I didn’t know I wanted but now can not live without. I love your content. You have inspired me to try for NUPOC.
I wish Taiwan had a half dozen of these boats. They have been looking for 6 modern diesel boats for a while but no one was willing to sell them out of fear of angering the dragon. They almost had a deal once but it fell through when the builder backed out. Maybe they can get India to build them some Kalvari (Scorpene) class subs.
Those are FRENCH boats mate!!. U cant just built n sell to someone else.🤭
@@kentershackle1329 They are french design boats made in India under license. France could avoid the political hassle of selling directly to Taiwan by merely providing support while letting India conduct the sale.
You’ve got the surfaced and dived speeds the wrong way around. 10 knots surfaced and 20 knots dived.
Are you sure about that?
I assumed it was higher surfaced because they could use their diesel engines that way.
@@theralfinator No, modern submarine hull shapes are not efficient on the surface with that blunt nose. All diesel electric subs have similar surfaced and submerged speeds.
@@briananthony4044 Modern submarines probably roll alot while on surface....the round shape dont look stable on the water haha
@@hippoace One of the comments on an earlier video from a sub-mariner said that even when the sub is deep, it can roll from the effects of a surface storm.
Thank you for the video; it was very interesting. It speaks well of the Swedes that for a country with a small population (about 10 million) they produce some very high-tech products.
I wish you still did Cold Waters streams. I know you got bored with them but I really enjoyed rookie jive Turkey admitting mistakes were made during torpedo beats.
If you mean subs like you guys. Yes. Somethings fell in place after some time.
Stirling Engines are pretty cool how they work, while I'm sure the Gotland's style is more complicated and classified, its really more like an "external" combustion engine as the basic versions you can even get as a desk toy use an external flame to heat up air in a tube with a piston and that causes the motion of the piston that turns drivewheel to get your rotational movement. There's several videos about them out there but I'm curious how they made the one for subs that work as well as it does. Really cool, really old tech
I always thought that the Sterling was a brilliant reimagining of what a combustion engine can be; ultimately improving in a variety of ways. Similar to a Wankel rotary-type of design in terms of thinking completely out of the box & leveraging a genius level of understanding of the basic principles of engineering which constitutes the core foundation of all internal combustion-type engines.
Saying that stirling engines is pretty cool is only half the truth (they have a hot side too ! )
@@superdepronic I see what you did there. Yup, a hot and a cold side. Neat external combustion engines.
@@MrTylerStricker Except the Wankel started life as a mechanical supercharger design for conventional piston engines.
@@MrTylerStricker The problem is that they're shite for torque for the most part, though that can be amended. But even then, they are bulky and have a very specific rev range that makes a direct transfer of power completely impractical, thus adding more weight and requirements in the form of a battery-motor system, etc. None of which are, of course, much of a problem on a damn submarine. But still, for use in cars and trucks? Nah...
Hard to believe that one of these puppies is significantly cheaper than an F-35!
Not really india sent a problem to mars cheaper than Hollywood made the movie
The f35 packs a bigger punch.
@@mercurio822 No. No it does not.
The conversion between USD and SEK is way off.
We've got ourselves to blame for that one I think... You'd think Biljon and Billion would be the same thing but nope, lets make it confusing.
FMV stands for 'Försvarets Materielverk'. I don't know what language that picture was in but that's definitely not it.
Good catch. thank you.
'Feyziye Mektepleri Vakfi' is (according to a brief search online) apparently a turkish educational foundation.
The speeds quoted here look odd to me. I've seen them reported the other way round (11 knots surfaced, 20 knots submerged when using the batteries, and much less when completely relying on AIP). Post WW2 sub designs (and even very late WW2 with the type-XXI U-boat) tend to be optimized for submerged performance, so it would be an odd design decision to optimize for surface performance on a boat where the design brief was better under-sea endurance.
I'm a little surprised the americans didn't buy one from SAAB. I would think this would have a good use case for coastal defense around Norfolk, NYC, Boston, etc.
Why would we buy a single ship to guard 3 cities and 100's of km of coast line?
@@koc988 true. Ten would be better
Another excellent sub brief!! This is a very interesting class of boats I've never heard of before, which I thought somewhat shocking considering their history/capability. I always enjoy learning about Russian & US boats, but this was a surprising & welcome change. Thank you cpt Jive Turkey for your dedication & hard work!
I’d love to see Jive Interview Rear Admiral Jens on the channel.
Why is this “sinking” by Swedish sub considered revolutionary? The US had sunk carriers with subs in WWII as did japan against American carriers, and in war games, American barbell class, Netherlands walrus class etc. have sunk carriers in exercises prior to the 2005 exercises. Maybe Sweden has better PR?
Maybe because they knew the sub was coming , threw everything trying catch her . In the end she busted Murica MODERN ASW invincibility. ?
@@kentershackle1329 like i said, previous subs including American subs have sunk carriers in real life and in exercises. Also Jive himself said his nuke carriers sunk carriers in exercises. So what’s the big deal?
@@gj1234567899999 Because the sub cost 1/10 of what the aircraft carrier did
What becomes of the Stirling engine exhaust?
Some minor things:
BREGT is not a Swedish name, unfortunately. The governor of Skåne is named BENGT Holgersson. At 7:00.
Jens Nykvist has a new job as the Swedish Military Representative to the EU and NATO, at the Permanent Representation of Sweden in Brussels. The new chief of the Swedish navy is a woman named Ewa Skoog Haslum.
"Sweden's not in NATO!"
Said the Swedes whenever the Russians inevitability marched into Stockholm on my Cold Waters campaigns...
In a unprovoked attack, in 2014, Russia invades Ukraine and with zero response from the rest of the world seizes the Crimean Peninsula. You'd think Sweden would take notice and reconsider that NATO membership dealio.
@@gblan will never happen. Sweden has inofficially been a part of nato since the 50:s. But if the general public would realise this there would be an outcry of biblical proportions.
@NA Phiri Russia has a tendency to create beefs with neighbouring countries now and again, though. Sweden is VERY aware of this fact. That we are not yet a part of NATO is pure politics and ignorance.
@@gblan Sweden has partnerships with NATO but no alliance.
We have an agreement with Finland for mutual defense & it also states that we both have to enter alliances together, Finland also does not want to join NATO as Russia would absolutely retaliate.
Sweden historically has also had a different approach to Ukraine, that is to be as spikey of an invasion target as humanely possible. Sure, Russia would likely win, but at what cost?
@@gblan that's a little bit simplistic. Both Ukraine and the Crimea have in again out again relationships with Russia and its empire. How can the original capital of the Rus was Kiev.
Think of the Ukraine as an island that emerges from the water whenever Russia is weak. Likewise Poland and Germany.
Hello SUB BRIEF, that reminds me of the year 2001, when the German submarine U24 approached the "USS Enterprise" up to torpedo range.
Surfaced and submerged speed have to be the other way around.
So typically American! Why do not you tell the whole story ?? When the captain of the aircraft carrier pooped on himself when evaluating one of the war games after in the Mediterranean in 2000. When he claimed that the Swedish submarine probably did not dare to get close enough. And the captain of the Swedish submarine showed a picture of the aircraft carrier and asked is this the "ship" you are the captain of? 😂😂😂😂😂 Otherwise, most things are correct🤔
Viking Captain. Arrrrrghhh.
This is why I drive a SAAB 9-3....that distinctive Griffin Badge on the nose...creator of epic aircraft and naval craft...and a serious 6-speed Turbo car. !
Regarding the story of breaching an American carrier screen: didn't the German 206 (U 24 i think) did something similar with the Enterprise in 2001?
Correct, during JTFEX 01-2.
Meh, we do it every two years at RIMPAC.
As usual an amazing story of another great vessel. Thanks for the content.
tip:
Nykvist is probably easier for you to pronounce as New-quizzed.
But it´s nee, not new
Fascinating video! I wish you'd explained a bit about what happens to the exhaust in the sterling engine...

The flooring in uppland is even made of sound absorbing material and you get a sense that they built this thing to be silent first and foremost then efficiently in command and control
I saw a similar set up in the German type 212’s as well so the Swedes and Germans defiantly have had a chat about it and come to similar conclusions
I think there is a small mistake. 2.1 billion SEK shoud be about 200 milion dollars.
I worked for a bank for 5 years. A lot of people got very rich and I don't work there anymore.
Dear Sir - 1.40 into your video wrong logo/language/ you are showing a logo for a turkish foundation FMV - Feyziye mektepleri vakfı not the FMV Försvarets materielverk - The Swedish Defence Materiel Administration - Just saying
I had been wondering how this system worked for ages
One interesting excercise: invite a US sub to play hide and seek with the Swedish navy in the Swedish archipelago.
Perhaps a bit unfair considering the size difference :)
The new ASW torpedo 47 just entered servce in the Swedish navy it will replace Torped 45. It's a 40cm electric torpedo
I thought US Navy is not strange doing war games with allies' diesel submarines. Japan has the largest and the best diesel submarine fleets among the US allies.
Waited for it, its really silent assasin i sailed near Gotland island two weeksago, and even saw ORP Orzeł submarine going for trials ;)
Come on! She can do 11 knots surfaced, 20 knots submerged on electric engines and 5 knots submerged on AIP. It's not a god damn WW2 submersible! It's a submarine!
Really ?
And how much tonnage have sunk the Swedish sub force in total ? ( comparing to the Germans )
@@georggellen9920 ... what has that got to do with anything?
@@LarS1963
Simply . The Swedish Navy has zero experience in real war. They also lack will to defend ( and die) for own country too.
@@georggellen9920 And what experience do the Germans have? I mean experience after WW2? None. Which equals the experience of almost every nation on Earth. Your statement adds nothing and is ridiculous.
@@georggellen9920 If you think the Swedish armen forces are not ready to do their duty, I don't think you realise how dedicated and professional they are... To whom are you comparing them, really? No soldiers wants to die, but they will most likely do everything they can in order to fulfull their obligations their country. Swedes are no exception.
Great info, but just wanted to point out that you have quite a few video glitches.
I find the fact that this sub uses a sterling engine fascinating!!! I have never seen one really do anything except for those little demistration models.
Jens is like Yenss, all the Skandinavian languages pronounce j like a y. Great video! Takk! CJensen
Whenever I hear a sailor calling the sea "the water"...
Thanks for your work.
there is a new type under development
Canada should’ve bought these instead of UK lemons, which we bought four, that way we have parts for the only 1 that’s ever seaworthy
You night struggle with Dinner with Jens, but since he's Swedish, you might have better luck with a Naked Sauna :D
I think you made an error on the exchange rate. 1 Swedish krona is about 0.12 USD(12 cents) Thus 2,1 billion krona is about 252 mil. USD.
Excellent information. Thank you.
FYI: "Sjöormen" translates to "Sea Serpent" (old sub and sub class first built in 1968, and all 5 boats sold in 1997 to Singapore) .
This is the submarine that got me interested in submarines, I'm very happy to see you doing a sub brief on it
I thought the speed was the other way around, 11 surfaced and 20 submerged.
Just imagine a gotland Just chilling on the ocean floor and spying on a cv
Thanks for the amazing brief Jive. Just a little mishap: the FMV logo at 1:35 belongs to a Turkish private school, not the Swedish Defense Materiel Administration which also have acronym FMV 😉
Helium is the working gas in the stirling engine. It's kept in a closed system and is not mixed with fuel or oxygen. From the beginning, the fuel was white spirit but since diesel fuel has gotten so clean (low sulfur), now it's used instead.
Thank you. I would have like more information on the operational aspect of the AIP when employed tactically, for example Nuclear versus AIP. I have been familiar with the Gotland being used as a training tool for the USN and was hoping even more information than was presented.
Normally USN does not see it self as vulnerable, usually with good reason, but what changes did USN undertake as a result of a "cheap" submarine "killing" a super carrier multiple times?
Being that it's about the vulnerabilities of at least some ships that are still sailing with the US Navy, it wouldn't at all surprise me to hear that most if not all the info about what the US Navy did to fix its perceived vulnerabilities is still classified to this day.
Wait, wait, wait! It is good to have a competent opposing forces to actually help you get better!
yeah, only we didn't get better.
@@SubBrief But that means you learned something from it. Still a win.
@@SubBrief there is a RADM or Capt who was Ltjg or Ens who is now making changes based off that AAR, but No Adm wants to here his ideas are trash! Hope...fully?
@@SubBrief at least not much after the U-24 "event" from 2007, when the trusty old 206A "sunk" the Enterprise XD
Watching your series has really triggered my interest in studying submarine propulsion systems
the design is like to understated...
That usd sek exchange ratio is waaaaaaaay off...
I might have forgot to carry the one... also, this is a very old video.
Kockums, It's pronounced (Cock-Uhms)...I get why you did your own take on the name 😎😬😉
Also HMS Halland will be upgraded. First it was said that only Gotland and Uppland would be upgraded but recently, it has been decided that Halland too will get the same upgrade. With the two new A26 underway, Sweden will have 5 modern submarines.
It must be galling for the Swedes that, after an advertisement like that, they didn’t manage to sell any for export in the way they did the Gripen.
Export of a weapons platform between states is 95% politics and 5% economics. The trials and evaluation is fixed so the correct (desired) platform is on top when it’s done.
Specially since the Australians were in the market for exactly the type of submarine.
@@jthunders That has certainly turned into one heck of a mess!
It'd be interesting to see how the type 212 submarine family compares to the Gotland class.
They're equipped with fuel cell AIP propulsion with virtually no moving parts (except for the main shaft obviously)....
mate, at 1:50 that banner FMV is an education foundation located in Turkey. It is irrelevant with context
Nice. Nice. Niiiice. P.S. What was that Governor's name again?? Bregt who? Haha. J/k. Keep up the good work.
Just so everyone knows: Sjöormen = Sea-Serpent (translation)
Yes, but, how do you pronounce that...
The closest swenglish kind of pronounciation would probably be like : Scheau-ormen.
That 2 year lease would make an amazing movie. The most unstoppable and largest navy vs a small peaceful nations 1 of 3 subs......
Admiral Nykvist is, as of 2020, the military representative and special attaché to the Swedish EU-representation, having stepped down as MC. He was flotilla commander for the First Submarine Flotilla 2013-2016, and then MC from 2016 to 2020 (MC would be the equivalent of the US CNO position).
His successor, Ewa Skoog Haslum, is a surface combatant, and the first female Swedish flag officer.
Dam!! Nitrogen helium oxygen and fuel...sounds like NASA rocket fuel!!
Her Captain's name is pronounced "Yens Neekvist".
