German manned rocketplane. Study 1944. Manned, winged boost-glide version of the V-2 missile. It would have been capable of delivering express cargo 600 km from the launch point within 17 minutes.

Other variants would form the second stage of the A9/A10 transatlantic missile.

The A4b designation was used to disguise work on the prohibited A9 program. Two prototypes were flown; a manned version was planned. The A4b had an empty mass 1350 kg greater than the basic V-2, with wings of 52 degree sweep.


Crew Size: 1.

Gross mass: 16,259 kg (35,844 lb).
Payload: 1,000 kg (2,200 lb).
Height: 14.18 m (46.52 ft).
Span: 3.20 m (10.40 ft).

  • A9/A10 German intercontinental boost-glide missile. The A9/A10 was the world's first practical design for a transatlantic ballistic missile. Design of the two stage missile began in 1940 and first flight would have been in 1946. Work on the A9/A10 was prohibited after 1943 when all efforts were to be spent on perfection and production of the A4 as a weapon-in-being. Von Braun managed to continue some development and flight tests of the A9 under the cover name of A4b (i.e. a modification of the A4, and therefore a production-related project). In late 1944 work on the A9/A10 resumed under the code name Projekt Amerika, but no significant hardware development was possible after the last test of the A4b in January 1945. More...
  • A9/A10/A11 German winged orbital launch vehicle. The A11 was planned at Peenemuende to use the A9/A10 transoceanic missile atop the tubby A11 stage to form the basis for launching the first earth satellite - or as an ICBM.... More...
  • A9/A10/A11/A12 German orbital launch vehicle. The A12 has been named as the designation for a true orbital launch vehicle, as sketched out at Peenemuende. It would have been a four-stage vehicle consisting of the A9+A10+A11+A12 stages. Caluclation suggest it could have placed 10 tonnes into low earth orbit. More...
