They use a special Skid on which the F135 sits.

In summery.
Step 1. Remove power module from shipping container with crane.
Step 2. Lower module on to skid on trailer.
Step 3. Roll trailer to ramp of CMV22.
Step 4. Rub hands and stretch vigorously.
Step 5. Carefully whinch power module and skid off trailer into V22.
Step 6. Secure tie downs.
Step 7. Ready for take off.

Wow fits so snug!

Consider V22 is a pretty narrow body anyway. The internal bay of a V22 is 7.8m long 1.8m wide and 1.8m tall.

For comparison the British Merlin interior is 6.5m long, 2m wide and 1.8m tall
Well the Chinook is 6.7m long 2.1m wide and 1.9m tall.
So? A 2019 Toyota Corolla is 4.37m long 1.97m wide and 1.43 m tall so well you could squeeze that car into the Merlin and Hooker you can't fit it through the door of a Osprey.
Osprey was designed off the old Sea Knight helicopter which was designed to carry a post world war 2 Jeep. This has resulted in adoption by the Marines marines and US Socom forces of specialist narrow body vehicles for use with it.
And in regards to the F135 power pack means a tight squeeze. For any personal getting a ride it also changes things. C2 Hawkeye had a school bus style seating front to back. V22 seating is face to face.

"Dry-Dock Sinking Could Accelerate the Russian Navy’s Decline [...] PD-50, a huge floating dry dock at the 82nd Repair Shipyard in Roslyakovo, Russia, accidentally sank on Oct. 29, 2018 after an electrical malfunction resulting in pumps overfilling the dock’s ballast tanks [...] Admiral Kuznetsov, Russia’s sole aircraft carrier, was aboard PD-50 at the time of the sinking. The carrier remained afloat but suffered damage from a collapsing crane [...] Russian officials have downplayed PD-50’s loss. 'We have alternatives actually for all the ships except for Admiral Kuznetsov' [...] That alone is a big problem for a fleet with just one carrier. 'It’s not clear what will happen to Kuznetsov now' [...] The Russian government might have to choose. It could spend potentially tens of millions of dollars raising and repairing PD-50, all in order to repair some 30-year-old ships for a few more years of service. Or it could decommission those ships and replace them with new, smaller vessels."

what was the solution for the V22 for COD with regards to F35 engine transport? pallet or no pallet?

Huh? In seven major deployments I've NEVER seen any jet engine transported in any COD or helo. There are jet engines stored below decks in supply spaces. I have seen engines lifted by helo from supply ship to the carrier. But NEVER aboard any COD.

I'm pretty sure I made a similar statement years ago.

I just checked and found this photo of a F-35 engine in a Osprey.

Based on this guys stories it's not a capability the Navy could rely on during your time in service.


Early C2A were less then the bird they became.
To transport an engine requires either a transport stand or cargo cage to prevent the engine from bailing out during carrier cats.
With E mail I imagine that paper letters are less important than they used to be. But packages are still popular and more critical would be spare parts.

another thing is the declared need of an Osprey for transporting an F-35 engine: it probably is just a spin, as ones F-35s become truly operational (I don't mean public stunts with a ship full of contractors), a decade or decades from now, only squared away machines (not the LRIP stuff) will be taken on board as ALIS may even work by then

OK and if an engine got damaged anyway, they'd just leave that aircraft in a hangar (again, in real world situations, not with journalists around)


I'm not going to respond to any comments

Unlike an airbase where you have the extra space to leave birds waiting for repairs Navy carriers don't have the space. So if a bird did have a damaged engine one of 4 things would happen. The first of which for all is removal of the damaged engine.
Option 1) take it to the jet ship to fix.
But if that doesn't seem workable.
Option 2) pull a spare. The ship will have a limited number of extra engines.
But that word limited is there.
Option 3) would then happen where in durring resupply a helicopter would chopper over replacementsfor the spares.
However that can take weeks as the engines have to be on the supply ship in advance.
Which is where Option 4) comes in.
Fly one out on V22.
