I'm sure the some of the roughly 200 or so F-22s can somehow manage to be where ever the Navy might happen to be to protect the Navy from what their OLD F-18s and out classed F-35s can't handle.
Folks made similar arguments about the F-18 when it first came out. The Hornet now has more combat experience than any other aircraft flying and is arguably the most succesful fighter/attack aircraft ever built.
The services put very tough requirements on F-35 and it has come through very succesfully. It will be a world class aircraft. And from my previous post to DevSix, the Navy wont need F-22 for fleet defense.
