The American Hermes Missile Project began in 1944 in response to Germany’s rocket attacks in Europe. After the war, with the help of captured German rocket scientists, General Electric assembled V-2 rockets at the White Sands, New Mexico Proving Grounds. The first Project Hermes V-2 launch in April 1946 reached only 3.4 miles altitude. The maximum altitude reached by the project in 1946 was 114 miles.
