Status: Study 1965. Gross mass: 7,300 kg (16,000 lb). Height: 8.17 m (26.80 ft). Span: 4.88 m (16.01 ft).
The main stage was 8.17 m long, had a 4.88 m wingspan, and could accommodate a payload of 24.4 cubic meter volume. The 7300 kg gross weight included a separable manned aircraft of 6.4 m length, which had a delta wing of 62 degrees sweep and a span of 4.05 m. The vertical stabilizers turned down from each wingtip. After the mother ship had re-entered the atmosphere, the manned aircraft would separate at Mach 0.6 and 9150 m altitude. Equipped with a single turbojet, a nose wheel, and aft landing skids, it would proceed to a landing at a conventional airfield. The main stage would descend to earth under a parachute and be recovered for re-use. The whole concept was strikingly similar to Chelomei's Kosmoplan, which was being cancelled in the Soviet Union just as the TRW study was completed.
