So 76 B-52H models going forward? I seem to recall around 42 being combat coded, a few dozen more with various reserve/attrition coding, and about 90+ H still intact, with 12 still at AMARC in 1000/inviolate storage (with GhostRider escaping a few years ago, the only B-52 to date to do so). I note the pondered order is for at least 608 engines, but would imagine another 10-20% for spares? An impressive order indeed.
