Why Aircraft Carriers Lost One Arresting Wire?
Vložit
- čas přidán 2. 06. 2024
- We were curious why new aircraft carriers have only three arresting wires instead four on older Nimitz carriers. While the answer may seem obvious, the exact reason for this change is not what you think, or is it?

My brother was in the Air Force and stationed at an AFB in New Mexico. Occasionally, Navy pilots would come thru to do some training and he said the Air Force pilots were astounded at how quickly the Navy pilots would put their aircraft onto the runway when landing and how rough all the landings seemed to be. The Navy pilots explained that they did not have the luxury of a mile long runway at sea and preferred to get the wheels on the ground ASAP. The landing of a carrier aircraft has been described as a controlled crash. The landing gear and airframes of a carrier aircraft are extremely robust in comparison to a land based aircraft because of the punishment they undergo when slamming down onto the deck and then being stopped dead in two seconds.
The two most useless things are altitude above you and runway behind you...
1:08 that prowler just turned into a hornet how that was smooth
OMG I didn't even realise it XD
WOW! Didn't even realize myself as I was editing that! To me it was just a plane! That's what happens when you edit 10 hours a day! (editor here)
Forget stealth, morphing planes is the real deal 😎
@@NotWhatYouThink dude you literally made the smoothest transition imaginable without even noticing LMAO
Nice catch. The guy with the pimple on his head is still there
"New tech" "we added more lights to the indicator"
But more light mean more detection to be displayed
Also mean Christmas tree
8k monitors are just 1080p monitors with more lights
Perfect example of "So hard to appreciate things if you don't understand em."
Back in 1997
Well... he also "forgot" to mention that we are witnessing the rise on computer assisted carrier landings. Greatly improving accuracy. Many planes already use this and ofcourse every ucav does.
My friend was in charge of the arresting wire under deck, he said that the old systems decapitated and mamed seamen all the time if malfunctioning, the spools of wire snap under tension or get red hot if not greased constantly and break. Same with anchor crew, lots of hazardous jobs on board the carriers. I think it is one of the most interesting armed forces, every job is important.
Arresting cables are about 1 inch in diameter - so they are heavy - and they are traveling the same speed as the aircraft that just snagged them. There are CZcams videos of arresting cables breaking in use, and yes, they can severely injure sailors.
I only recently saw a below decks arresting wire video. A long time ago I saw a very old video (as @JoeFrickinFriday points out) of a wire break that clipped a guy. Only now did I wonder, what is the fallout below deck. I can only imagine it's catastrophic to man and machine. Do you know how different the poly cord system is as far as breaks. Everything breaks eventually.
Whoever told you that these cables break all of the time was not honest. I use to run and maintain the engine for the 3 wire on the Eisenhower and daily maintenance is done. I've only seen old videos of them breaking but never in my 6 yrs.
@@giantfisher They don't break like people think. They check the wear on the cables and the cable you see on the flight deck get changed after it catches about 95 planes. They have a material like rope inside of the cable and they put a liquid on it which the rope like material absorbs and keep it lubricated.
''All the time''
Do you mean like 3 or 4 daily?
Or more like 8 or 9 per week?
"3, take it of leave it"
BULLSEYE!
of
"I would take it *of* leave it."
More like take it or fall off the edge.
Good to know. I’ll remember it for when I land my F-18 next week
Have you landed?
Bravo lol he went into the sea
Major flex 💯
Guess you could say he had an F/A - Sinking?
Rip
I'm pretty sure the biggest reason they went from 4 to 3 was the massive improved accuracy of digital ILS (instrument landing systems) in all the aircraft from the 70s to the 2010s. One of the biggest selling points of the F35 (especially to foreign nations) is the auto-land ILS capability, which can stick the 2 wire in zero visibility with minimal input from the pilot (so long as the sea state is not totally unreasonable). You don't need 4 wires when your landing patch has been drastically shrunk by improved avionics technology.
Nobody:
The one admiral who had always hit the 1 wire: haha, LSO you cant touch me
There’s Admirals still flying?!
@@F3PIZZA yes I think lol
@@paniojanlouisea.5453 hella badass!
No, once you hit Rear Admiral Lower Half you stop flying. RALH is equivalent to a Brigadier General
@@F3PIZZA I'm not so sure since I'm a Pilot of a MobileSuit lol
1:06 mind boggling edit morphing from A6 to F/A-18! Haha, had to watch it a few times!
Actualky it was an EA-6B... And not really morphed... the Prowler was a lot closer to the deck than the Hornet when the clip was spliced in...
@@CH-pv2rz ok
this CAG dude man... this is truly how the whole military vehicle community is. Will never dive into it because of how obsessed some are about details in life.
@@no3ironman11100 Nothing wrong with being exact.
@@no3ironman11100 You won't last long in technical MOSs if you aren't concerned with the details.
The Fresnel lens indicating system is similar to the PAPI lights at an airport, allowing pilots to judge their glide slope for a safe landing

I worked in PLAT/Lens on the USS Midway, CV-41 and USS Ranger, CV-61 from 1980-1985. My work center was responsible for operating and maintaining the “Lens” and the closed circuit tv system that filmed and recorded all flight operations. The upgrades look great!
In my opinion, Aircraft Carriers are the most enthralling and amazing military machines ever created.
I'm retired Navy with over 400 traps. This is a great overview and explanation!
Really? What did you fly and in what squadron? On what cruises did you go to sea?
@@CH-pv2rz RF-8, VFP-63 Det 4 on the Independence East coast, 1980 (Shellback AND a 6 pack of beer!).
F-14A, VF-114 two cruises on the Enterprise, 1984 and 1986.
Were you CAG on any of those?
After that, did a tour in VF-126 (A-4E/F and F-16N - my avatar) and then VFC-13 A-4 Superfox (retired out of the reserves) while flying with Delta Air Lines. Retired from Delta 3 years ago.
@@CH-pv2rz You know, now I'm curious. Were you a CAG?
that sounds cool
what is a trap? is that the term for landing on a cable like this?
5:01 RIP promotion.
What's messed up is the tailhook actually touched right between the 1 and 2 wire, and bounced over to the 3rd wire.
2:05 I love how they cut it just before bro started dancing
1:08 were just going to ignore the smoothest transition I've ever seen
ok
I didn’t even realize it was a transition, good eye
What? are you saying Prowlers don't turn into Hornets on final approach? 🤯
@@jollyrogerhobbies2386 bruh he's not smart enough to know about it
@JollyRoger... No they only do that in the groove... The Navy doesnt fly an approach.
@@CH-pv2rz ah, good point Commander!
I spent 3 yrs on USS Kitty Hawk (CVA-63) from '69 thru '72. Saw many, many traps, but never flew either on or off the deck.
That aircraft design transition at 1:06 was the smoothest edit I have ever seen!
The French carriers have practically only had three wires, but it's for space reasons
Chicken and egg problem. Space reasons - designed that way - money - functionqlity - safety - specs - aircraft capability.
@@ekevanderzee9538, agreed. But not only. Long studies and practices produced the same conclusions. Reinforced by similar equipment, training methods and interoperability constraints.
Enjoyed your informative videos! Love them! Thanks! Subscribed!
This isn't what I thought about landing cables, good video!
1:14 Gave me flashbacks of playing Top Gun on NES😅
I somehow managed to land on my first try back in the days, all other attempts failed 😂
You definitely give some very interesting information. Thanks 👍
2:05 Guy in the back looks so cheerful
So weird sitting on the flight deck of the Bush watching this vid and seeing the equipment at the same time
Lmfao stop flexing bro
@@MauricioBarragan lmfao it's not a flex bro
im going to eat the boat
@@mememanfresh do it I don't want to work tomorrow
@@EMN_Sandwich I gotchu bro
Keep up the great work! This went from random facts to facts about primarily Naval vessels.
We like that didn't we
We find that there are plenty of interesting topics to cover about the Navy/Airforce. That said, we are thinking about slowly introducing new (interesting!) topics that are still not what you think 😉
Great video.
Just an awe inspiring vessel.
"MK" is pronounced "Mark."
It's not a "Frezz-nal" lens, it's a "Fruh-nell" lens.
Thanks for pointing these out. It helps us improve our future videos 👍🏼
I did not do this, i did not.
Oh hi, MK
if talking about german auto cannons it’s not pronounced mark however as it means maschinenkannone
But it’s spelled Fresnel.
@@MothaLuva it's french that's why it's spelt wrong
Great information.
Great work sir👍.
I love how his longer videos are always about something you didn’t think would be so detailed
You could say it’s-
I was wondering why RR had 4 Rat Holes, when only 3 of them had Arresting Gear coming from them. Thanks for the info!
One of the few no BS youtube channels ✌️
Thanks for posting wasn't in Navy aircraft carrier many years ago
Very interesting.
Thank you.
Good to know!
I'll try this the next time I find myself in a fighter jet 💪🏻
Thanks!
Ok
Wow. You made 10 k subs in a week.
Well done!
Man i love your video
I love these no-bullshit informative videos!
I remember that one video where the arresting wire snapped. Had no clue what the wires were or what had happened, now I do, and I am kinda terrified
A really nice explanation
FYI, in naval terms, MK is shorthand for "Mark"
*in military terms
Yes
MK or Mk is also used in Air Force and Army designations to denote "mark". Like the Spitfire Mk V (Spitfire Mark five) or SMLE MkIII (Short Magazine Lee Enfield Mark three) It is also used in various civilian designations, from cameras to pianos to cars.
@@matthewmcgee Fair point, only had knowledge from my time in service at sea.
Yah , like Tejas mk2 light combat aircraft of India.
Nice information tahnks.
I'd have a hard time not shitting myself landing on a aircraft carrier with a metal rope being the only thing stopping you from diving off the end
i’m pretty sure they push the throttle to full power after landing just in case it snaps or they miss it so they can take off again, but yeah i know what you mean
try playing warthunder and not use a naval air craft
that’s why they gun it, if anything happens they just go around and try again... then get get ragged on because they missed. i forgot what they call it
@@todx15 True. But I'd still have a hard time not shitting myself 😂
@@flamingrubys11 lmao i kinda wanna land a mig21 on a carrier now.
god that is probably the best OLS explanation i heard,this thing always confused me how it really worked
IFLOLS
improved fresnel lense optical landing sys 🙂
@@AtomicBabel thanks alot,im gonna read about it
@@votpavel agree,this is the best description of these things. One item to add is that those big red lights are the wave off lights. So as you're watching the ball, and the thing turns red, you are going around.
@@AtomicBabel ah ok thanks
I agree, he did a good job on that one of the best I've heard and I was a Fresnel Lens tech...I only seen an IFLOLS in San Diego. But the datum lights are actually blue they just look green :)
That was cool 😎, nice video 👍
2:10 "Mk" is always pronounced "MARK" as in Mark 7 (Mk 7) arresting gear, Mark 48 (Mk 48) torpedo, etc. Nice video!
And "fresnel", as in fresnel lens, has a silent s.
Very informative,
In short: The first wire was never used anyway.
but now they positioned the wires so that tge first wire of thr 3 wire system is also useless
@@carlosandleon So, they didn't remove the first wire but the fourth.
@@Yora21 I guess so, the video does mention the first wire of the 3 wire system is roughly there where the first wire of the 4 wire system was
And yet, the video shows the one wire getting snagged. (and a three from the hook bouncing over two)
Oh yes they were. But it was not a good landing. And if it was a TAXI 1 WIRE, even worse. That meant you were really close to the ROUND DOWN (stern).
My experience has taught me glide slope precision is everything --- an absolute must
Worked on flight deck for 3 years, in the seventies, we were very aware the wire could break and kill ya. But we never broke a wire. ! It’s called good maintenance.
Thank you Yankee Doodle. This is very helpful video.
-Chinese Navy.
Good info. From a former naval aviator.
Nice video
Wow that's cool, I never knew that. Thanks for posting, very interesting. Now back to practicing my Case 1 in DCS World on Ole Abe 😁
That was a pretty slick edit starting at 1:07. One minute you see a Prowler the next you see a F-18.
Damn lol
It's very good information video sir
Also, the arresting system is stopping a plane *at full throttle* (if they miss, they need to be prepared to go around.)
FADEC will spool down the engines once the trap is assured. It's not like the plane starts towing the ship along at the end of the trap.
The real reason for getting rid of #1 wire is because of Officer's getting hit by grease shot at them when they would cross from the starboard side of the O-3 level to the port side through #1 engine room by the engine operator with the grease gun powered by the ships l.p.
a. supply.
Would not surprise me one bit👆
I’ll remember this piece of information the next time I try to land my fire aircraft on an aircraft carrier. Very helpful.
No you wont
2:13 Never seen a plane doing summersault before 👏.....
What humanity can achieve if it works together is simply inconceivable
The "marked improvement" of the multi-lens fresnel lens system is inferior to a Laser Centerline Localizer (LCL) and the laser Glideslope Indicator (LGI) system that was perfected in the early 1990s. Tighter tolerance, superior distance especially through precipitation, and easy to see through peripheral vision long after the fresnel lens system left their field of view. The few Navy pilots who gave it test runs wanted it but politics kept it off of the carriers.
Wasn't that the precursor to Long Range Lineup?
4:48 We don't see FLOLS or IFLOLS but rather MOVLAS. MOVLAS is the manually operated visual landing system. It can be used in emergencies or high seas conditions to give the LSO more control over approach aircraft glide slope.
Thank you
There must be 1000 ways to die on an floating runway. I see widow-makers everywhere I look. 😳
Mk-7 MOD3 Hydraulic Arresting System
m = maximum mass of aircraft = 50,000 lb = 22,680 kg
v = maximum landing speed = 130 kn = 67 m/s
t = deceleration time = 2 s
d = deceleration distance = 344 ft =105 m
KE1 = kinetic energy of aircraft when landing = to be determined
KE2 = kinetic energy of aircraft when stopped = 0 J
Kinetic Energy of Landing Aircraft
KE1 = 0.5mv²
KE1 = 0.5(22,680 kg)(67 m/s)²
KE1 = 50,718,851 J = 50.7 MJ
Power
P = power absorbed by arresting system = to be determined
P = KE1 / t
P = 50,718,851 J / 2 s
P = 25,359,426 J/s = 25,359,426 W = 25.4 MW
Comparison:
2.4 MW = peak power output of a Princess Coronation class steam locomotive (approx 3.3K EDHP on test) (1937)
3 MW = mechanical power output of a diesel locomotive
8 MW = peak power output of the MHI Vestas V164, the world's largest offshore wind turbine
28 MW = peak power output of the reactor of a Los Angeles-class nuclear submarine
At 1:09 you can see an ea-6b approaching for landing, but when the camera zooms out, its changed to an f-18.
But they look like the same people-
@@Shadow-sq2yj it’s the same people but the planes change. Take a closer look and focus on the jet when it approaches for landing
Oh nice I never knew they have a similar thing as PAPI lights on land as well
1:08
Apparently that's a prototype of the navy's new shape-shifting aircraft.
Or possibly some unintentional side-effect of our editing. You be the judge 😉
@@NotWhatYouThink Let me guess - you can neither confirm nor deny whether you got to see a fighter using new, classified transformation tech operating off of US carriers? XD
Very interesting
Lets not forget about SPN - Whatever version is active now. SPN -46? It will carry a plane for about 10 miles out to touchdown on the deck if I recall.
Super cool love the big ships
An interesting fact is that on a big deck carrier they have LSOs who are Naval Aviators who talk to the pilots as they approach the deck giving them advice the whole way down. Now on a Gator or LHD or LHA class carrier with F35Bs and helicopters they use an LSE landing Signal Enlisted who guides the helocopters in. Just thought I'd put that out there.
Last time that I was this early, the USSR still existed.
Same, I remember the good old days of O U R T U B E
Last time i was this late the USSR was back in business
I now know why the Brits have VTOL carriers 😂
Yea... Sorry guys but we are to cheap to give you 4 wires, so you only get 3. Because 1 extra wire costs so much more than an F-35 or an E2 does... Right? ...No? Oops!
and it was a british invention
@@CH-pv2rz which doesn't make sense because the Ford wasted slot of many using all toilets and no urinals in an attempt to be more female "friendly"
@@CH-pv2rz You do realize that the 3 wires is just fine, because it the new tech makes 3 wires just as good as 4 so why even make the cost for the new one?
@@CH-pv2rz pilots were also told not to aim for the first wire anyway, so its really just removing unneeded equipment to save maintenance costs. "Dont aim for the first because you might go too low and crash, aim for the third, but hitting the second and fourth are okay" i wouldnt be suprised if eventually the system is reduced to 2 wires to eliminate the issue of coming up short, since theyre aiming for the same spot on the deck, just without the rearmost wire
Lol been on three carriers. Now that im out I miss the flight deck lol
"...Then shalt thou count to three, no more, no less. Three shall be the number thou shalt count, and the number of the counting shall be three. Four shalt thou not count, neither count thou two, excepting that thou then proceed to three. Five is right out. Once the number three, being the third number, be reached..."
Exactly 😁
Are we talking wires or Holy grenades?????🤔
I'm sorry. Was that three ?
U deserve 1 million subscribers
We are working toward it 😅
Thanks!
Thanks very much! Glad you enjoyed the video :-)
1:08 OMG the navy have aircraft that can change form
Here comes the conspiracy theories lol
Serious multi-mission capability!
Shapeshifter transformers.
Shoutout hope you cross 100 K fast
What do you mean?
Why on the thumbnail did it say don’t catch this; ITS the one thing you’re supposed to catch
Wow, I'm early.....by the way, could you make a video sometime about the new arresting system....that would be quite interesting I would think.
Slept under the TR's 3 wire for 2 cruises, the screech from the the ag would make your ears bleed.
Same here... USS Enterprise.... many moons ago....
Under the 3 wire on the USS Independence 84-85. Next to Cat 2 on the Forrestal 85-87. I can sleep through anything.
Worked and slept between the number 1 and 2 catapults on the USS Constellation during her last cruise. When I got off the ship I cou”don’t get to sleep, it was too quite....lol
@@RazgrizF14 It was only after my 1st cruise, Indy 79', at the end of the cruise there was a sarcastic (with a lot of truth) letter aimed at Navy wives, back then just wives, on how to make your sailor comfortable upon his return. How to simulate GQ drills, water hours, jets landing on your head, no fresh milk, at the end of the cruise it was funnier than living it. I still have it in an old cruise book in the attic.
To my shipmates, in case you didn't know, with a little searching on the Naval archives all the past cruise books are accessible. It is always cool to see shipmates and liberty buddies from 40+ years ago.
2:22 the carriers number was almost perfect
funnie
For that, you need footage of the USS Dwight D. Eisenhower.
"MK" is not spelled out as "M...K". It is a military designation which is pronounced "Mark", as in the "Mark 7 hydraulic system". Every weapons system, ammunition, etc, which has MK at the beginning of its designation is identified like this (ie: MK 19).
Its so beautiful to see aircrafts landing on a carrier. It brings me Swordfish flashbacks.
Fascinating!!!!!😀😀😀😀😀😀😀
FYI, the "s" in Fresnel is silent. I know, I know, nit picky, but I thought you might want to know. Actually, a description of the Fresnel lens and how it works, might make interesting reading for some viewers.
Thanks Jim. Yes, others have pointed out the silent “s” too, and we have corrected it in a future video 👍🏼
Because I took it.
It's mine now!
Deal with it.
Hello, police?! This man stole a wire!
Police: you'll have to buy it back or I'm going to put YOU in jail.
In my time in the Navy, the cables were changed about every 100 traps.
That's right.
Well that all looked simple enough, right up until 1:44 when we see what it's like landing in the dark. Wow.
I'm a pilot and this sounds like the most difficult imaginable
Fresnel is pronounced 'Fruh-nel'. Not 'Fres-nel'.
French inventor. It's a very common type of light-focusing lens from lighthouses, signaling lamps, to theatre lights and street lamps.
& it's also VERY LOUD on the 03 level ...
The lens system is like the PAPI lights basically?
Very nice. Wheres the ramp?
At the stern.
Why do V-2 arresting gear personnel push the purchase cable into the landing area during retraction? It's not what you think.
The S in "Fresnel" is silent.
