As true as that is, most of the projects you mentioned there were not as international in purchase and input as the JSF is. If Congress did pull the pin on the JSF, then their would be a couple of cheesed off countries who put large amounts of money into a project some beauracrat recommened to be scrapped. This is a major project not just for the USAF, but every other Air force and the US Defence Industry. if it were to be scrapped, every project worked in conjunction with US and Allies would be viewed Sceptically and funds might not be as forthcoming, which would not help anyone.
They are beyond the cancel point really in terms of everyone elses involvement, and i don't see Congress recieving a good review from the friends its got if they lost out on future international contracts, just because the USAF can go F-22, doesn't mean everyone else will, more likely out of spite some might look elsewhere, ie typhoon. which leads to an even bigger loss in the long term. And this revolves across the board, with Army or Navy upgrades.
Too many factors now to see an end.
True, the JSF is an international effort, and its going to be hard to kill the program completely as such. But, and there is a but, I can guaranty that before its said and done that the F-35 program is going to be restructured to contend with reduced purchase quantities. 3000 airframes? Yeah, right and we're also going to see the USAF get it's 750 F-22 aiframes. I've been around long enough to see the writing that is on the wall of the F-35 program and there are more (-)'s to (+)'s coming down the road. My armchair prediction is:
USAF: 500-700 total program buy
USN: 200-300 ""
USM: TBD
And per unit airframe cost ~ 80-95M USD
It would be cheaper for the US to simply give back the money collected from our international partners and cancell the program outright and actually field more F-22s, Strike Ealges, Super Hornets, UCAVs, and ALCMs.
Though Kurt Plummer is a little out there, he is right and the F-35 is going to wind up being a tanker hog, and worse yet a tanker hog for the sake of delivering TWO bombs (not counting SDB). There is already a platform than can carry two bombs internally, and carry them further/faster to target and generate more sorties per airframe per unit of time: the F-22 which has the benefit of not needing to be flight tested and have 'bugs' worked out during and extensive flight test program; which has the benefit of already having been production tooled. For that matter, considering the international cooperation in the F-35, it wouldn't be *that* difficult nor *that* expensive to build an internationalized F-22 for export. Considering how 'electronic' the F-22 is, it could be programmed (w/o supplying source code to the other nations) to fly at reduced cruise speeds, and its radar set could easily be downgraded such that the USA maintains a supperior fighter/bomber which is the prerequisite for the international cooperation/export of the F-35.
Its rare to see logic ever applied to the US defense industry, so we'll never see the 35 cancelled or an export version of the 22. We will only see reduced buys of the 35 and increased per unit costs. The last two aircraft that the generals kept their noses out of were the A-10 and YF-16, and we all know what a success each of those aircraft were/are.
What the US air forces need are more C-17s, C-130s, tankers, F-22s, Super Hornets, AWACS (USAF/USN), Strike Eagles, UCAVs, a better AMRAAM, a better ALCM, and new build B-1s -- not a two bomb carrying 275 billion dollar airplane that is a step backwards in everyday performance of what is already in production. For the first time in US history the generals have seen fit to whip up a plane that does not have everday speed, range, altitude, payload of whats already in production. Sure the F-16 was slower in top end speed than the F-15, but top end speed is never even flown at briefly in combat situations. The F-16 could also more than hold its own in a turning engagement with the F-15, and I find it highly unlikely that the 35 will be as comparable to the F-22 and is the F-16 comparable to the F-15.
