Early Milestones

Formation of the Soviet rocket program under Sergei Korolev

Aug 1946

Sergei Korolev was appointed chief designer of long-range ballistic missiles, laying the organizational foundation for the Soviet space program. Drawing on German V-2 technology and Soviet engineering talent, his bureau at OKB-1 would go on to develop the rockets that launched the first satellites, animals, and humans into space.
