The KC-46 is somewhere at $5B in losses to Boeing (the USAF wrote the program contract defensively, for once) and years behind schedule.
And as for bombers, Northrop Grumman is at the pole position with the B-21 Raider contract.
The B-52 will be flying forever, but that can't be a major revenue win for Boeing.
The F/A-18E/F is getting a bit long in the tooth, and the Navy (and Air Force) are both starting up new fighter programs (aka Next Generation Air Dominance, separate for each service).
