With the B-1(A) cancelled, Rockwell took a look at a variety of bombers that ranged from “deliberately low technology for the sake of development time and risk” to “LASER GUNS” (seriously). The bomber needed to have a payload of 50,000 pounds, mostly in the form of sixteen nuclear-capable cruise missiles. It needed a strategic mission range of about 5,200 nautical miles with said payload.

The five main examples were:

• Subsonic, low technology/cost
• Subsonic, lowest weight
• Supersonic
• Stealth
• LASER GUN

The resulting report makes for very interesting reading. One of the more interesting proposals that’s mentioned but not elaborated on there is the modular plane that could be a bomber, an AWACS, a transport, and more.

What implied stats emerge (I’m not an aviation engineer) show the cargo version of the bomber as having neither the raw payload capacity of a heavy airlifter (the payload charts only went up to about 40 tons/80,000 pounds) nor the ruggedness of a light one (the takeoff distance, though impressive for a heavy bomber, is less than a dedicated airlifter). And that’s even before considering the issues with a modular pod (there’s a reason why very few transporters like it have been built). Still fun to think about.
