Obi Wan..oh great Master Jedi.:D. remember years ago you drew a ski ramp on a LHA/LHD? If you still have those pictures available could you please post them? Thanks!

What's the MTOW & fuel/weapons bring back with a ski jump launch and SRVL recovery? I know SRVL enables a return with internal weapons (2xMRAAM + 2x1000lb PGM), but is it enough to provide a sensible buddy refueling capability? Internal fuel fraction on the F-35B is not exactly generous for an aircraft which can't rely on drop tanks, and while it gets away with very modest reserve fuel on landing (no need to accommodate a serious risk of a bolter), tanker support would not go amiss.

Also, the JBDs seen on some artist's impressions do not appear to be fitted - any info on the reason?

VIDEO: U.K. Carrier Program Brings ‘Two More for the Good Guys’ as Royal Navy Set to Partner More with U.S., French Navies

"The 70,000-ton carrier and its sister ship, Prince of Wales (R09), and their embarked air wings of F-35B Lightning II Joint Strike Fighters are set to be the centerpiece of Britain’s nascent carrier strike group construct. The move – after years of starts and stops – is reshaping the Royal Navy from a force that was a key NATO partner focused on anti-submarine and mine warfare in the Cold War to one that will blend closely with the carrier forces of American and French allies."

if in the future an engines for example takes in a flock of birds or is roughed up by shrapnels and if they then replace it on board after an Osprey delivers stuff, instead of just leaving the aircraft in a hangar, I'll be proven wrong
and the USN is working to prove me wrong LOL as
Navy’s COD Transition from C-2A to CMV-22B Accelerated; First V-22 Deployment Set for 2021

The Navy has accelerated the sunset of its legacy C-2A Greyhound cargo airplanes and the transition to the CMV-22B Osprey, with the new tiltrotor aircraft now set to deliver in Fiscal Year 2020 and deploy in 2021.

covers the final Marine MV-22s as well as the first 39 CMV-22s that will serve as the next-generation carrier-onboard delivery (COD) aircraft.

During a House Armed Services seapower and projection forces subcommittee hearing on Friday, Rear Adm. Scott Conn, director of air warfare on the chief of naval operations’ staff (OPNAV N98), told lawmakers that the transition was already happening as fast as possible.

“We have accelerated the sundown of the C-2 from 2027 to 2024. We have our first (CMV-22B) aircraft being built in Philadelphia today, going down the line. That aircraft will deliver in FY 20. We then have to do a modified [operational test] and [developmental test] and the only thing … we’re testing are the things different on the CMV-22 as compared to the MV-22. So that’s going to be a very compressed test,” Conn said.
“We then [reach initial operational capability] and get our first three aircraft to deploy in 2021. There is no means by which I can accelerate that any further. When you look at the [military construction], the training that’s required for our sailors to operate and maintain and the aircrew that have to fly it and get the hours they need, we’re going as fast as we can go.”

There are three main differences in the CMV-22B compared to the Marines’ MV-22B. The Navy’s aircraft will have an extended-range fuel system, a high-frequency beyond line-of-sight radio and a public address system in the back of the aircraft.

Due to the similarity in the aircraft, the Navy has already begun training with the Marines’ Osprey, with an

Conn had been asked if there were additional funds the Navy needed to help get out of the legacy C-2s faster, and he said that, on the back end of the transition, “any additional aircraft at this point would relieve or provide a shock absorber during the transition, as we go from transition to deployment in follow-on detachments until we’re completely divested of our C-2.”

Subcommittee ranking member Rep. Joe Courtney (D-Conn.) had asked about additional funds for the CMV-22B program, noting that the C-2A fleet was aging and facing diminished operational availability. Conn said the planes were 30 years old and were “nowhere near where we want it to be” in terms of operational availability. Investments in aviation readiness yielded some improvement, with the planes hitting 40-percent operational availability in 2018 compared to just 32 percent in 2017, but he noted that wasn’t good enough to support a globally deployed fleet.

Despite the readiness challenges within the C-2A fleet, the planes had had an impressive record of safety until one

in December, but Conn said in the hearing that the plane may not be lifted from the sea floor until next summer.

“Our recovery and salvage efforts: we have the 22,000 feet of Kevlar cable to recover the aircraft that is at 18,000 feet of water in the Philippine Sea. We have to do some follow-on testing with the winch and the salvage vessel to be able to reel up this aircraft,” he said.
“And then now that we’re in typhoon season in that part of the world, we’re going to have to wait for the seas to abate. Our best estimate right now is, when we look at the conditions the ocean will provide, we’re looking late spring, early summer of next year.”

The investigation into that crash is still ongoing, he said.

JBDs are not required with a rolling takeoff and ski jump launch, if you watch the videos of such launches, whilst the aircraft is stationary, not just the lift fan door opens but the aft engine nozzle can be seen rotating down about 45 degrees, so that it provides both vertical lift as well as forward momentum. The lift fan is disengaged and the door closes once the aircraft has reached about 130-140knots, and the nozzle rotates aft at this point as well. Fuel margins can be intentionally very tight on return to the ship, as there is no requirement to keep any in case of a 'bolter. With STOVL aircraft, you land on the deck first time everytime, and you don't want more fuel as deadweight than necessary.42707493_394639537933204_4427427604986855424_n.jpg As you cab see here the nozzle is providing both vertical lift and forward momentum. As the jet blast is aimed at the deck for the most part, aircraft ranged behind aren't on the receiving end of nearly so much jet efflux as if the nozzle was pointing horizontally straight back. Tests on land proved there was no need for JBDs, so they were dropped from the design over ten years ago.
