The question is whether combining all that tech into one airframe is worth it. Could we have built essentially just two different planes with drastically different capabilites and design, but sharing this line radar absorbent materials, the glass, etc for cheaper?
If we wanted a strike fighter for the marines, really it needs a data link, a decent radar, and a bunch of weapons and fuel. I get the feeling the B is going to be used as essentially a stealth harrier, which we could have had combat ready by 2010.
Granted the A and C models would need greater capability, eliminating the B as a tie in would simply work to an extent.
I just feel that weapons design has really become too integrated, too advanced perhaps. We look for complex solutions to simple problems.
