Aggregate 9/10
The test stand VII of the HVA Peenemünde was dimensioned for the “America rocket” when it was built in 1938.
Size comparison A1 to A10

Unit 10 ( A10 for short ) was, together with A9, the world's first project of a transatlantic ballistic missile . The planning phase of the German missile project began in 1940, the first flight was planned in 1946. A10 was intended as the starting stage of A9 (manned and unmanned) to enable an attack on the USA, so towards the end of 1944 the name "America rocket" came up. In 1943, however, the continuation of the project work on the A9 / A10 was prohibited, since at that time all efforts were directed towards the perfection and production of the A4 rocket . However, Wernher von Braun was able to circumvent the ban by choosing the code name Aggregat 4b for the A9 and thus creating a connection to the A4 rocket. This made it possible to continue the project work and some test flights, but the project work was discontinued after the last test with A4b in January 1945.

A10 should be powered by alcohol and liquid oxygen. The thrust of the engines should be 2000 kN, the burning time 55 seconds. The diameter should be 4.12 meters. Test rig VII in Peenemünde was designed for the launch of this rocket, which would have exceeded unit 4 in size , when it was built in 1938. A new rocket factory was built in the Austrian Ebensee concentration camp for the production of the A10 .
