A lot of armchair quarterbacking (once again) by those who don't know shit. Nice real-sounding but not exactly accurate numbers. The JSF isn't the end all-be-all fighter plane, but it'll work, and it'll work a lot better than it's being given credit. The alternative is...what? Buy a less capable airplane than we have now (the foriegn jobs, for all their hype) or wait till the wings fall off the Hornets/ Vipers/ Harriers, etc? Legacy Hornet production lines been closed since 1997. While the Block 60 Viper's impressive, there's not much growth left there. JSF should still be viable long after the legacy jets, even in their most modified and updated forms, are no longer survivable. Besides that, the average age of a US fighter/ attack type aircraft is just plain getting old, and they have to be replaced, or else they'll start falling apart (re the Missouri F-15 from 2 months ago...)
