John F. Kennedy (CVN 79) Dead-Load Testing
HTML-код
- Опубликовано: 21 фев 2024
- Newport News Shipbuilding recently began topside testing of the electromagnetic aircraft launch system (EMALS) on aircraft carrier John F. Kennedy (CVN 79).
Following successful “no-load” testing on catapults one and two, known as the ‘bow cats,’ the NNS team, alongside the John F. Kennedy crew, has now started “dead-load” testing. In this phase, large, wheeled, car-like structures of graduated weights up to 80,000 pounds to simulate the weight of actual aircraft are launched off the carrier’s bow into the James River. They are then retrieved and relaunched until the conclusion of the test program to ensure the catapults are ready for their primary intended purpose: to launch all carrier-based fixed wing aircraft flown by the U.S. Navy.
The first dead loads used in this testing have special significance. Family members of shipbuilders signed them with messages of congratulations and gratitude during the shipyard’s Family Day held in October.

Very cool. But honestly, I'm here for CVN-65 in the background. 🙂
Me too, sad to see the 'Big E' going away.
Oh, wow. I thought they were way further along in the scrapping.
@@neuman35Remember she has (had?) 8 reactors. That's a lot of meticulous disassembly that has to be done.
@@Whatsinanameanyway13remember she’s been sitting there or 10 years.
@@Whatsinanameanyway13Isn’t she next?
Wow! Good to see the new Kennedy almost done. I did design work on the old Kennedy CV 67, Ford CVN 78 and the old Enterprise CVN 65. Great to hear that the EMLS is going well compared to the Ford.
The Sorry Sarah, (Saratoga)? I was on her in the early 90's for four years.
I would surely hope that they worked out the kinks in the EMALS or else that would be awful. Sure, they built-in way too much new tech into the Ford class, and there were lots of teething pains to fix, but in the end it will all have paid off.
@@oceanic8424 I think they have worked out those kinks. The Ford just did a really long deployment that surprised me and seems to indicate that things are working well.
No camera on the carts?????
@@ghostmourn Yes, the new launch and arrestor systems(EMALS/AAG) are working great and are performing above expectations. You don't cruise the Middle East with sketchy sortie generation capability.
Good to see the EMALS working so well, but it was very sad to see, in the background, the condition of my old home, CVN65.
It will cost about $1 billion to safety scrap the ship with toxic materials and 8 nuclear reactors (1 wasn’t working for a while.). CV65 original cost was about $475 million in 1958 when ordered, the most expensive ship to that point. CV67 was about $290 million, and that’s when it was decided to go nuclear in the future. CV78 was about $12 billion, not including some R&D costs.
@@tonymanero5544Yes, but it’s a billion pumped back into the ship breaking economy. 👍
One day soon.....I'll see the Ike in that condition and I will be devastated. I spent 15 of 23 years on her.
Wow, it's pretty crazy to see CV 65, the most recent Enterprise partially disassembled, next to JFK knowing JFK's new sister is a new Enterprise.
Side note; I wish we'd stop naming ships after people and would get back to naming them after ships of the past. There should be another Kitty Hawk, Hornet, Ranger, Yorktown, Saratoga. I also really wish they saved the names America and Constellation for new Ford class CVNs.
CVN-81 should be the uss America for sure
The USS America is an amphib now, first in her class. Although I suppose you could call her a baby flat top.
@@jimwjohnq.public She doesn't have a well deck so she is purely an aviation ship. I guess having an America as a part-time "lightning carrier" is better than no carrier named America.
And with Constellation, I am actually pretty ok with the new frigates named after her since a Constellation was one of the first frigates. If the USN doesn't name the next few Constellations after the Original 6 (minus Constitution of course) it'll be a big missed opportunity.
@@jona.scholt4362 Well, they have Constellation, Congress, Chesapeake and Lafayette, so while the Lafayette isn't one of the original frigates, Marquis de Lafayette is an American Revolutionary War hero! Now the next two just need to be named President and United States!
@@dundonrl next frigates should be named after Revolutionary naval heros like Conyngham and Wickes
The first time I saw people skipping rocks, I was amazed that something so solid and heavy could bounce off a liquid, given the correct angle and sufficient speed. To see something weighing thousands of pounds do the same thing just blows my mind 😄
I know!! My 7 year old son said daddy let’s skip your car! 😂 😂
My ship is in the background. *salute* Enterprise!
EMALS acceleration profile is so smooth - that's impressive.
Anyone else see the irony in the US Government naming the most expensive warship after a man the US Government had assin ate ed?
That’s awesome. As a kid back in the 80’s I had the opportunity to go on the original JFK when she came into Boston Harbor for the tall ships celebration. It was great talking to the F-14 crews of the “Tomcatters”
I was on there when it came to Beantown,an amazing ship at the size of it , and to think they are even bigger now
I was there too. We got about 10 feet from getting on the ship and my grandmother couldn’t stand to wait any longer. 😭
Enterprise was sailing when the old Kennedy was sailing
Now she's here watching how far we came with the New Kennedy right alongside her
It's hard to believe CVN-65 is now 65 years old.
I got to see the final testing on CVN 78 2 years ago and it was amazing knowing that the rails are powered by magnetic coils under the deck.
When Ford left the dock, we went to the Kennedy and pulled miles of wiring throughout the ship.
What an experience! It was the hardest earned money I have ever made. I will always remember that shipyard.
They do know that electrical equipment and salt water don’t mix right?
Attention everyone we cant have insulated wiring in ships bc they sail the 7 seas. Are you being serious w/ that comment dude lmao? @blipco5
@@DefendTheStar you obviously have never worked with marine cables. They're sealed and filled with rubber between the wires and going inside the wall have a double seal to keep any water out of the enclosure.
The USN goes to great lengths to keep the equipment in running order. Engineers a lot smarter than you and I have done extensive research on what works and what doesn't. I agree with you that water and electricity don't mix. Neither does nuclear reactors but they're making it work.
@@DefendTheStar I’m just wondering how the protect the electrics on the catapult from the seawater?
Thank you shipbuilders! The thousands of lives of US Navy sailors are in your capable hands. Bravo Zulu!
out to sea your life is in your own hands sonny boy - typical yardworker is a lazy bastard
When I was working on Carriers at Puget Sound, deadload day was my favorite. I would always contrive a way to watch. Since my assigned work area was always the Flight Deck and higher, that normally wasn't too difficult.
It was fun watching these tests on both of my carriers when we were in the NNSY. Thanks for posting this video!
That's really amazing to see. It's also interesting how the light 7800 skips whilst the 18000 just creates a massive splash
I believe it's the first ship with refined EMALS, Elevators and Plumbing to fix the first in class issues. Excited to see it get to shock trials!
CVN-65 USS Enterprise, the legend in the background.
You guys make the coolest stuff. Thank you.
this is pretty cool, but my attention may have been stolen by _Enterprise_ observing from the next spot over
Ditto!
I love technology, big machines, and American power! Keep on keeping America safe !!!
I was on the USS Constellation (CV-64) when it was in the SLEP Program in Philly. I remember watching these trials on my signal bridge
They used to do dead-load testing in Bremerton too but don't any more. Was very fun to watch.
kinda poignant to see Big E on the next pier
Sad to see her in that condition.
Think these ford carriers are going to be in a much bigger war, might be why the Big E hasnt been torn down as fast in case that class has some value
Is it the new big e?
That’s our American shipbuilders! Giving their best to build the best ships that protect our country and interests! God bless them all!🇺🇸❤
My first Deployment was on the Kennedy flown out to her in winter of 92 meet my command vfa-105, latter on completed a full work up and deployment while stationed with VFA-86 she was port at Jacksonville, Fl, short drive their but still managed to get a ticket.
When I was a kid, we used to go down to Long Beach harbor a lot. One day we saw them launching these things off an aircraft carrier at Long Beach Naval Station.
So cool to see the Navy’s newest CVN right alongside the first ever CVN.
I worked on the old JFK as a college student during the summers. Watched the dead load tests .
Do they retreave the dead load?
@@johnwhodat8135 They do
@@johnwhodat8135yep, they float - Tug boats pull them back over to area where crane can pick them up and put them back on the flight deck.
This is awesome to see. Im a machinist and we build large RO pumps for various nuclear warships. I helped make the pumps on this glorious ship. Its so awesome to actually see what we build.
Fun to watch from the water on the James River too!!
Good watch, interesting to see.
However, nothing like loud music over the top of someone talking to reduce effectiveness and enjoyment.
I like the dead-load skips but those drone shots of the nose-unders with that green water is just plain cool. lol
"On the boat" they used to fire the catapults for tests, etc. with nothing on them. We called those shots "no-loads." My rack on one cruise was right next to the track for Cat 2 three feet from my pillow. I slept like a baby.
She can really sling it, can't she?
RIP USS _Enterprise_ (CVN-65) I spent 6 weeks aboard her for one det. I almost felt like it was an honor.
Great Videos
Sad to see that old steam system go away. I built catapult valves in the cat panels many years at Leslie controls
That’s awesome.
I did my Med cruise on the old JFK CV-67
I don't care what excuse you all gave to do this, this is just fun to watch and you all earned that pat on the shoulders and a drink from all of us who are proud of you. Good work Ladies and Gentlemen.
God bless these great men for building the best military equipment in the world. We are in awe of your talents and appreciate your hard work. Thank you very much❤️
Thanks also for keeping the old Enterprise presentable as well, until she can be scrapped. Great work though on this mag catapult! Fun to watch.
Going to be interesting to see the CVN 80 Enterprise when it’s finished
Evel Knievel is back and back at it again.
These really are amazing weapons, a steerable floating military air base. Glad to see we're still on the cutting edge thanks to everyone involved, like I'm reading in the comments seem to have been involved with past carriers.
Great job guys!! You are protecting the future of the United States! THANK YOU!!
Do they recover the test sleds? If not, there must be a ton of them on the bottom of the harbour!
They do recover them. They float.
@@stanstenson8168thank you! I feared that they were so heavy, to match an airplane for testing, that they would sink to the bottom.
Probably cost couple of hundred thou each
@@JohnVincent29it's the Navy... Million each is more like it
@xephael3485 Hell yeah.
That's so cool.
0:28 that was SPECTACULAR! 👏
They do that with every carrier after a yard period. We did it on the USS America (CV-66) back in the '70's. They would hook the sleds up to the cats and shoot full power shots with them. Flung them a fair distance out into the river.
I love the USS. John F. Kennedy CVN-79, but USS. Enterprise CVN-65 “Big E” sitting off of her port side will always be my most favorite Nuclear Powered Aircraft Carrier! She started it all back in November 25, 1961 when she was commissioned.
Are the deadweight sleds recovered afterwards for reuse? What’s the water depth where they are shot?
Testing my arse, their just having fun!
Imagine riding that bad boy like Tex
if that's a brand new boat, what do they do about all the rust on the flight deck? do they remove it before putting the final coat on? or do they just go over it,
i see it a lot when certain parts rust on ship builds and always wondered what they do about it
Just a stupid question: do they retrieve the dead loads from the water? If not, won't they accumulate in the bottom as the testing of this ship progresses (combined with the testing of past and future ships)?
I know, retrieval would be expensive and economicaly not worth it, but it would prevent building up an underwater obstacle, and provide an interesting training exercise for the US Navy divers. Any thoughts on this?
They might float?
Have they ever considered self-inflating salvage pontoons for the catapult sleds?
Of course they did...Rejected out of hand, they're painted bright orange, they know where they landed and EOD/BUDS rescue and salvage divers all need training evolutions.
The Navy NEVER misses a chance to do things the hard way!...I was active duty CVN-73 (George Washington)
Means that the sleds are recovered manually by divers?
Good for training the divers!
Otherwise they could have some sort of cable with a floating thing at the end to ease recovery.
The test sleds all float (even the ones that weigh 80,000 lbs)- Tug boats pull them back over to area where crane can pick them up and put them back on the flight deck.
Forgive me for asking a stupid question, but what is the advantage of using a magnetic catapult as opposed to a more traditional steam driven one?
So do they capture the sleds when all is said and done?
I wonder how they power the EMALs for this testing. Are the reactors already critical and generating power? Or is this coming from shore power?
Well at Lakehurst we didn't have a reactor
The Ford seems to have solved its technical challenges because they just finished a massive deployment! This ship will be even better so I think the US Navy has a really good and very modern new class of carrier here. Well done.
Pls show us a second vid where they resque those dead-loads from the sea.
Very cool to see the testing. Each launch reminded me of several presidential campaign launches and how they ended this year.
Do they recover the sleds, I wonder??
Yes, they float.
So will the Ford class boats be able to fit in PSNS, WA dry dock, or are they only able to have maintenance done at NN, VA?
She can fit in PSNS. If she needs drydock work, especially needing big blue the crane, its NN only.
Dave says "cool"!
Do they retrieve the sleds afterwards?
Wow..new carrier..cvn.79....👏🙏🙏😘😘💪💪💪🇺🇲
are the sleds recovered post launch?
CVN 68...MY SHIP!
That was cool to see! The music was bit obnoxious though.
RIGHT ON BROTHER!
I was at the Brooklyn Navy yard , 1966 when the first JFK Docked in Manhattan, it was big , i was on the USS WASP CVS .
I know little about this so pardon my ignorance. Initially I thought it would be pushed but now I can see that it's being pulled. At the end of the pier / ship, if it is being pulled how is it released?
if it was pushed it would be very unstable. The way the planes work is they have a little arm on the front nose gear that locks in and when the puller reaches end of travel it stops hard, releases that little arm, and the plane has momentum and keeps going.
When I was 5 years old I dreamt about having a job like this when I grew up.
Whats the record for number of skips across the water when shooting off that test sled?
Do they retrieve these loads out of the water, or are they basically throwaway items?
Do they retrieve them or do they leave them
Plankowner CVN-75 & CVN-76. Watched plenty of dead load tests
I'd like to see how they retrieve those test sleds from the water as well.
Do you recover the test sleds.
yes, they float
Beautiful🇺🇲🇺🇲🇺🇲
Interesting the old Enterprise still looks pretty good next door.
I remember seeing one of those no loads where they hadn't put water in the break either :(
Nothing but a big chunk of steel at the end of the track afterward, huh? 😮
@@datsnuffydude5460 Bent like a pretzel and thick steel torn like paper
WOOooooooooo!
How do they recover the sleds?
They either float or divers attach lines to them.
@@jeremynew6449 @queenslandtrainvideos they float
The one sled had 78,000 lbs painted on it, probably near max for a US carrier based jet. With full power an actual jet taking off is well on its way all by itself, while the sled is dead weight with no engine.
I think the one in video said 7,800 lbs, but they do have sleds around 80,000 lbs (there was also a 51,440 lbs in the video)
Big E still hasn't been scrapped yet?
Scrapping will commence in 2025 next year. Most of the time has been spent on how to dispose of its nuclear reactors and who.
They were going to wait until Shatner passed on to turn her into razor blades however,……….THE SHAT WILL NEVER DIE! 💪🏼
@@benjaminperez7328Don't jinx it.
What is that sitting next to her? CVN 80?
New Sport how far can your sled go
I want to know how they recover the sleds they shoot off.
they float and tugboats pull them back to the peir
Are there any tickets left to ride the sled? 😮
I assume they recover those?
I was hoping to see a Plymouth Horizon.
Serve with courage! Amazing! Sleeping very comfortably at night because of the men and women who serve. These tools are operated with so much precision and talent, just showing up is sometimes all we need. God bless America!
Wow, WOT a ride! 😬
Generals gathered in their masses!!
And forgotten USS Enterprise (CVN-65) in background. Sad view.
Next to CVN-79 is big E:D
I remember sitting on Eisenhower, tied opposite to the Kennedy in 77 ,waiting to go shakedown ike..
After the tastings do they recover the test sleds?
Yes, they float.
@stanstenson8168 how does a solid 18,000 lb steel sled float? those tires definitely ain't floating that thing
@@middletnpyro same way a steel ship floats.....displacement.
@@markplatt1784 that thing doesn't look hollow, alot of other people are saying divers have to recover them
@@middletnpyro OK. I was in Newport News on the GW. They were launching sleds off the Stennis. They float.
Sooper Kewel !!!
How's about the Enterprise?
I think all the writing on the sleds is funny 😁
Are the orange sleds recovered?
yes, they float
