Not arguing with the marines they surely need new birds what worries me is the other versions for the air force and navy the marines primary mission has been close air support for jarheads on the ground
Relax Tulsa, what do you expect fielding a new fifth gen, why do you think the Russians and Chinese have a handful of fifth gens??? its expensive, and it very, very complex? it will come together, and it will be a very effective air to air platform in the end, it will do the do!
I am waiting for the first F-35 jockey to flame a Raptor?? that will be news, and no that won't be easy either. Lots of very high intensity work and training going on right now, to bring this bird up to speed.
