I'm not sure those technologies weren't already developed under the ATF contracts and then shared with the Japansese as part of the FS-X. To give any credit to the FS-X or the F-2 would be disingenuous.
Roscoe, I worked FS-X in the early-mid 90s. Japan wanted our avionics/flight control technology. We wanted their co-cured composite technologies. Those were the main issues of the technology transfer agreements.
I saw the F-2 wings being built in Ft Worth, and I've seen the F-22 panels, F-35 and latest F-16 wings being built in Ft Worth. I'm pretty sure on this one, trust me.

How about a F-117? B-2? The Raptor is very easy to take care of.

Esay is a relative term. I don't know about the F-117 or B-2 but I do know that a ten minute structural member check on an F-22 means two days in the LO shop to close it back up.
Anyone care to address the F-22 canopy coating delaminations?

Is that due to temperature cycling or do the F-16s and F/A-18s have that same problem?

My question was asked after I saw three F-22s at Bomber Plant 4 last week. One had major visible peeling of the outer coating, and the other two had evidence of "patching". No cameras were allowed so I don't have pics. The pilots said it was a constant problem that was being looked into but didn't offer more than that - and I didn't ask him to.

So what? Teething problems plague every new aircraft... once technology from the F-35 program is adopted, and maintenence practices and procedures improved and developed, maintaining the F-22A will be very easy in comparison to previous VLO aircraft, and even legacy airframes.

That's weird. Almost sounds like cheap, aftermarket window tinting rather than vapor deposition. I wonder if the adhesive is getting hot and outgassing causing bubbles.

My friend just attended the airshow at Nellis. He said the F-22 clearly turned tighter in the 360 degree turn than the F-15 and it performed a really tight loop to quicly reverse direction, if you want to call it that. He was very impressed.

I was at Nellis as well. I am now convinced the Raptor has an anti-gravity device the way that baby can hover and dance around. Wow. AS another poster pointed out, when the Eagle was putting on his show, Dozer was behind the crowd practicing...well not really behind the crowd, because a large part of the crowd was turned around to watch it instead of the Eagle (Which by the way was the last ever Eagle demo and that particular pilot's fini flight before retiring...what a way to go out!)

Dozer?? You sure it was him flying and not his replacement? He should be in Alaska by now.

Having worked in the engineeering industry, this is not unfamiliar with new autmobile paints/coatings. Sometimes it takes a little time to work out curing(?) and temps and thickness's.... No big deal to get worried about. I can also speculate that it's an anti-corrosion coating.... The US gov is phasing out certain chromium based coatings and there are teething issues with that.

Quite sure, they announced his name numerous times. Last show of the season however.

That's gotta suck. Apparently the T-birds were upstaged much the same way at Hill this year.
