Would make a better tanker & awacs aircraft for the carriers...
Only ish...
Their tanking capacity is relatively small, so you'd have to use lots of them to put a big F-35 strike at long range, and of course if you have lots of V-22's on your carrier you can't also have lots of F-35 - space being finite on a carrier.
The AWAC's angle also isn't as great as is sometimes suggested - while they fly higher than the Merlin, they aren't going to be flying
that much higher, and so their radar performance isn't going to be
that much better.
A great tanker and a great AWAC's would be massive improvements to the Carriers/F-35 mix, but the V-22 is neither, while being very expensive, taking up lots of very limited space, and being very complicated and time consuming to maintain.
If the carriers were bigger - thank you Gordon Brown - and cheaper (again, thank you GB), then the V-22 would look like a better option, but as we are they are too compromised, and too compromising.
