John F. Kennedy (CVN 79) Dead-Load Testing

- เผยแพร่เมื่อ 4 ต.ค. 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.
CVN 65 was in rough shape coming back from her last Deployment in 2012. She is beyond Repair, and would be too costly to even attempt to save it as a Museum. It's been 12 years since Decommission, and still no clear solution as to her Final Demise
My ship is in the background. *salute* Enterprise!
Is the new Enterprise being built yet?
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?
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! 😂 😂
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. 😭
I was stationed on the Kennedy then. Bostonians lined up for miles to tour the ship! Boston treated us very well! Next stop was Portland, ME and I think NYC after that.
That's really amazing to see. It's also interesting how the light 7800 skips whilst the 18000 just creates a massive splash
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.
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
It was fun watching these tests on both of my carriers when we were in the NNSY. Thanks for posting this video!
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.
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.
@@Jon.A.Scholt 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
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!
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
this is pretty cool, but my attention may have been stolen by _Enterprise_ observing from the next spot over
Ditto!
They used to do dead-load testing in Bremerton too but don't any more. Was very fun to watch.
I love technology, big machines, and American power! Keep on keeping America safe !!!
CVN-65 USS Enterprise, the legend in the background.
You guys make the coolest stuff. Thank you.
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?
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.
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.
Good watch, interesting to see.
However, nothing like loud music over the top of someone talking to reduce effectiveness and enjoyment.
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.
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.
So cool to see the Navy’s newest CVN right alongside the first ever CVN.
That’s our American shipbuilders! Giving their best to build the best ships that protect our country and interests! God bless them all!🇺🇸❤
Sad to see that old steam system go away. I built catapult valves in the cat panels many years at Leslie controls
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.
Oh dear, there she is ...... USS Enterprise, CVN 65 ....... that Lady NEEDS TO BE SAVED !
DONT LET HER GO THE WAY USS Enterprise CV6 went ...... She needs to be a museum ship , based at Norfolk,Va
All i can say bout it, but i choke up every time i see her , as she was a great ship, has a great name and served longer that many ships of her time ...... Anchors Aweigh !
she's so moldy and so much of the ship is radioactive its a major hazard. the port aircraft elevator requires a Geiger counter on your person to stand on per OSHA
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.
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.
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.
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 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.
That’s awesome.
I did my Med cruise on the old JFK CV-67
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?
I know Im probably being naïve, but I’ll never understand why we don’t put a proven ship like the Enterprise into ready standby status. With operational pressures gone, we have all the time in the world to do a complete upgrade and refurbish. We have a great hull and superstructure to work with. If nothing else, it would make a great drone warfare platform Why do we dump 90 Billion (?) to a Littoral fleet that is useless instead of preparing a ready to go backup. Thoughts?
Well, all of her 8 obsolete reactors were removed in the first six or so years after she was decommissioned, and large parts of her structure were removed to do so. It would probably cost more than a new carrier at this point to redesign and build her into something botched together that resembles a functional ship.
Former Enterprise maintenance manager here. She was a one-off ship. Very little parts commonality with others. Her hull was tired, her propulsion plant was pushed way past the breaking point, and her between deployment upkeep ran twice as long as other carriers.
One word, new and schiney!
Fun to watch from the water on the James River too!!
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❤️
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)
Do they recover the sleds, I wonder??
Yes, they 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.
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.
Great job guys!! You are protecting the future of the United States! THANK YOU!!
Going to be interesting to see the CVN 80 Enterprise when it’s finished
Imagine riding that bad boy like Tex
0:28 that was SPECTACULAR! 👏
Pls show us a second vid where they resque those dead-loads from the sea.
Evel Knievel is back and back at it again.
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.
Testing my arse, their just having fun!
So, what's the plan for 65? She's been sitting there for about 10 years.
navy just recently started a bid for shipyards to scrap her. its expected HII will win and she will be scrapped at NNS
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.
How do they recover the sleds?
They float.
Large Crane
Very cool to see the testing. Each launch reminded me of several presidential campaign launches and how they ended this year.
I was on the USS John F Kennedy CV67 for a year in VA75. My uncle was on the Enterprise CVN65 years before I was on The JFK.
Old JFK was a banger when it came out.
That's so cool.
When I was 5 years old I dreamt about having a job like this when I grew up.
That was cool to see! The music was bit obnoxious though.
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
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 .
Wow..new carrier..cvn.79....👏🙏🙏😘😘💪💪💪🇺🇲
And forgotten USS Enterprise (CVN-65) in background. Sad view.
RIGHT ON BROTHER!
CVN 68...MY SHIP!
Sad naming after presidents. That should have been America or Enterprise. This is from someone who served on Kitty Hawk, Ranger, America, George Washington, and Eisenhower.
They have gotten back away from it. After the new JFK, there is a new Enterprise, then the Doris Miller. Hopefully, they will continue to stay away from politicians, except maybe a replacement GW and Lincoln.
next one is enterprise
With hypersonic missiles one wonders how prudent building a large slow target is? Relegated to permissive climates?
hypersonic missles are over rated, the current SAMs on board USN ships can easily handle all known aerial threats, including hypersonics.
Carriers don't just float daintily about all by their ownselves, they are surrounded by several other type of ships, some underwater! Cruisers, DDs, DDEs, Frigates, subs and such.
I'd like to see how they retrieve those test sleds from the water as well.
Dave says "cool"!
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?
Plankowner CVN-75 & CVN-76. Watched plenty of dead load tests
Great Videos
Great!!! We built this, but do we have enough competent sailors to man it?
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
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
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!
Interesting the old Enterprise still looks pretty good next door.
Whats the record for number of skips across the water when shooting off that test sled?
Wife: What did you do at work today?
Ship builder: You, know.. the same [giggles]
Do they retrieve these loads out of the water, or are they basically throwaway items?
Beautiful🇺🇲🇺🇲🇺🇲
Usa navy please add 3rd launch in middle for alert 5 and possibly future large craft in cvn-80 , history has shown many non conventional military aircraft have landed before including a stricken c130 , it would be good if something could be done to return these craft to air after repairs than returning to port who knows if another futures craft or x plan may need to have extra wing space or frame than the two outer launchers
Wow, I really love to see the new USS John F. Kennedy (CVN-79) and it was fun to watch the Dead-Load Testinng, but my attention was also stolen trhough the USS Enterprise (CVN-65) in the background.
I find it really sad that a ship like the Enterprise has done so much for her country, has also starred in films and series and is the only one of her class and is still being scrapped, it disappoints me a bit and makes me sad. It would have been much nicer if the Enterprise, like the beautiful Iowa class, had been kept as a museum ship, because that's what she deserves and not a scrap!
I hope it can still be undone somehow and the Enterprise can still be saved.
It would also be nice to see if the aircraft carriers were given their old names again such as Hornet, Yorktown, Kitty Hawk, Essex, etc. instead of presidential names.
Now, when the Navy and Huntington Ingalls has completed testing, do they retrieve these objects out of the river, or do the lave them there as litter in the river? These objects must be removed from the river. As soon as possible. Go clean up your litter.
Are the deadweight sleds recovered afterwards for reuse? What’s the water depth where they are shot?
As a former Greenshirt (Plankowner CVN 72) I have to say the EMALS seems boring because of the lack of steam and noise. It's kind of like preferring a Corvette with all its noise and a stick shift over a Tesla because one is all about "feeling" the car and the power and smelling the engine and shifting gears versus pressing a button and going fast.
I remember sitting on Eisenhower, tied opposite to the Kennedy in 77 ,waiting to go shakedown ike..
do not show it to "admiral kuznetsov", although the power is for "testing purposes only"
How's about the Enterprise?
Wonder how many are down there.
I wonder how much Tech of the system here is in China's? Anything classified? I hope so. I've seen images of the Fords rail working. The control of the power, the capacitor banks not so much.
the basics are unclassified. the nitty gritty details are. doesn't take a rocket surgeon to make this... especially since roller coasters have been using this system for years. the difficult part is making the power generation and making it rated for 80,000 lbs aircraft and making it fail as close to zero as possible
I had no idea ships were being retrofitted with EMALS.
Retrofit implies that this is replacing a steam launch system that was installed previous. This ship is brand new and had the emals from the beginning. No ship will ever be retrofitted with emals. That would require tearing apart half the ship and likely require new power plants.
🙏🙏🙏
jst add wings,engines and tails an u'll get those things to fly...........😊😊😊
So do they capture the sleds when all is said and done?
I assume they recover those?
Cool 😎.. America engineering at its best...Now What happens to the launched cars? Are they recovered or left to RIP
they float and get recovered
