https://www.quora.com/How-much-does-one-airstrike-cost says (in part):
Bombers: B-2 Spirit Unit cost:$737 million
Armament:
80× 500 lb class bombs (Mk-82, GBU-38) mounted on Bomb Rack Assembly (BRA) ($2k each)
36× 750 lb CBU class bombs on BRA
16× 2,000 lb class bombs (Mk-84, GBU-31) mounted on Rotary Launcher Assembly (RLA) ($3k each)
So each bomber mission cost approx $240,000
Without maintenance, training, or repair costs . . .
They estimate the cost of each drone strike at $146,000, again without all the necessary maintenance and repair costs.
So . . . As of 2024, it cost $3.81 to make a school lunch, so we're talking more than 60,000 kids that could have been fed for the price of each airstrike.
