Aircraft Carriers III

[Jura The idiot]

Too low, too high, wrong speed ... as every approach to short runways on land.

I didn't ask what you pulled out of my post, and you pulled "I mean other issues" out of my post, I asked

"how frequent something like a bolter is expected to be with the SRVL?"

how frequent something like a bolter is expected to be with the SRVL? LOL I said "something like" (I know there's no cable involved) I mean other issues

There won't be any Bolters with SRVL. Once your wheels touch the deck you're already well below flying speed (about 70 knots or less and decelerating). If your breaks fail at this point you'll still stop, but the roll out may be longer, possibly even reaching the bottom of the ski jump, at which point gravity will help with the breaking force as you are trying to head up hill without the benefit of forward thrust.

There may well be 'Wave Offs' in bad weather/high seas, but that will be determined during the trials process. As I said, once your wheels are on deck, you have landed.

thanks, sounds pretty dangerous though (but that's me)

do you think the USMC will be looking at SRVL at all?

. Sometimes as a alternative to buying F35Cs for use with Navy CVNs. It may be possible for use by the wider LHA ops.
The main issue is however the size of the deck. U.S. LHA decks are smaller then the British Queen Elizabeth class.

What part of carrier operations is not pretty dangerous?
You are taking a multi million dollar aircraft strapped to a rocket chair with a armored transparent shell over your head. Have to take off from a deck to short to actually let you build up proper speed so you are either flung down a rail by steam, electromagnetic forces into the sea with the hope that you will build up enough lift to fly as opposed to splash into the sea.
or trying to generate vertical thrust more then your weight well riding off a ramp or balancing in the Air with out a net supported only by thrust.

You fly your mission and return to try and land by either being caught on a thin wire well in a stall and basically crash into the deck with engines at full throttle and hoping that the tail hook is not ripped from the bird.
Alternatively you try to either zero your speed and balance on in essence a cloud and gently drop to the deck or you use counter thrust and roll to a stop.
Mean time the guys on the deck are working around high explosives, fuel, rain, frost, snow, wind landing aircraft, taking off aircraft, debris from damaged aircraft, flying wires that would break bones if they snapped from trying to stop a 30 ton jet speeding into the deck. Or boiling steam and flying catapult shuttles, heavy tools and drone time to time spinning blades that threaten to suck them in.
I mean hell, the infantry guys at least get to shoot back when attacked.

"The main issue is however the size of the deck. U.S. LHA decks are smaller then the British Queen Elizabeth class."

The USN's Gators are 800ft long, the QECs are 920 ft long. When the F=35Bs conducted the first SRVLs they landed at about 750 ft from the top of the ramp and stopped at about 580ft, nearly a 200ft deck roll. I don't think there would be any problem with conducting SRVLs aboard a Gator...

@Obi Wan Russell
Well I agree with you it can be done. The factor that you are lacking here is the width of deck to.
Remember any such landing needs the Space ahead to be cleared that means potentially finding space to roll a waiting MV22
The Queen Elizabeth class is not just longer remember she is wider to. At her widest the deck of the Queen is 73meters, the America class is only 32 meters. Infact her beam is less then that of the Queen Elizabeth's waterline beam (39m). So you have a much smaller deck space to move things around.
Now again I don't think that is a mission kill for it. I think that the Navy and the marines will find a work around.

USS John F. Kennedy was at 75% complete in May. She will end up replacing the Nimitz. Some good shots of F-35Cs taking off and landing on the Nimitz at the end of this vieo, about the last 25%,

Another at 75% from May. The above video was from September 9th. This one is from May:

They used the amphibious assault ships with OV-10 Broncos. Using it with F-35 SRVLs can be a bit easier.

...

where would be 'savings generated by the SRVL' if an aircraft slammed it into the row of aircraft (for example starboard to the ski jump)

 

[TerraN_EmpirE]

The same accounting where a crash on a CVN deck would be Jura.
However that would require the jet not to have achieved transition to lift system landing mode in which case the pilot would likely throttle up and turn away from the deck. Or a bad situation anyway for the Jet to still have So much momentum and be banking hard to the right with the jet more likely to slam into one of the islands before the line of fighters.
