Simple Congress.......thats the answer
No, congress appropriates the money, doesn’t build the planes...
Looks like they are planning to buy 100-150 of the b21s with a rough 10-12 year widow.. So that’s a vast improvement over the b1 and b2s... but still nowhere near what we were cranking out in the 50s and 60s. Yes I know they are fare more complicated, but still... its not like the B52’s weren’t cutting edge for their time as well
