I saw that yesterday. IIRC, the B-2 production plans had pretty well been killed long before that and what he opposed was the effort to revive it. I believe it was a last ditch effort to retain the program. Too bad it failed--that plane is awesome.
Hunter got the funds into that bill for more planes. The first operational unit did not roll out until the end of 1993, so the production line was in full swing during that period. I know, I worked for a large unnamed aerospace company at the time that was making sub assemblies. :o)
