I'm thinking it's a new UAV/UCAV or possibly a new missile and not a sixth gen fighter. We didn't sell the F-22 to anyone else, we're not going to sell it's replacement to anyone else as well. I also don't think the new LM facility at Palmdale has to do with a new fighter, because it would make Roper's threat about switching over to the new fighter and cancelling the F-35 a hollow threat. That leads me to believe the fighter demo that flew was a Boeing Phantom Works product, since NG is busy with the B-21. Otherwise, why would LM see cancelling a further F-35 buy in lieu of the sixth gen fighter as a threat? OK, make us stop building this airplane (F-35) so you can buy that airplane (6th-gen fighter) which is newer and more expensive.
