Courtney/Ken/LO: thanks. I don't think it's a matter of requirement creep or mismatch, or "one size fits all" (which looks good to a budget weenie but has SRFA to do with combat effectiveness). With the varied requirements laid on the air effort, to include CAS, the "best fit" with F-35 is going to warp in part due to the program taking so long to get fielded. The world and war keep changing, and I suspect that like the B-2, JSF will arrive late for the show. IIRC, Sopwith Snipe arrived right as WW I ended.
Foxtrat Alpha: you said it more eloquently than I.
JSFfan: calling CM a troll ... come one, man!
