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...
Lox/Alcohol Liquid oxygen was the earliest, cheapest, safest, and eventually the preferred oxidiser for large space launchers. Its main drawback is that it is moderately cryogenic, and therefore not suitable for military uses where storage of the fuelled missile and quick launch are required. Alcohol (C2H5OH) was the fuel used for the German V-2 rocket, and the first derivative rocket engines in the United States, Soviet Union, and China used it as well. Better performance was achieved by increasing the alcohol concentration in the post-war engines. But after better-performance rocket-grade kerosene was developed by Rocketdyne in the REAP program of 1953, use of alcohol was abandoned. More...
