They were used for a wide range of military and scientific research; component proving tests; and as radar, ASAT, and ABM targets. More...
  • Kosmos 2 In 1960 the Soviet government decreed development of a lightweight launch vehicle for launch of payloads not requiring R-7 family of boosters. A modification of the R-12 IRBM was selected as the first stage; a new high-performance second stage was developed using a unique Lox/UDMH propellant combination. After two failures, the first successful flight was on March 16, 1962. More...

Associated Launch Sites
  • Kapustin Yar Russia's first missile test range and used for satellite launches of smaller Kosmos vehicles. V-2's launched from here in 1946 were the first ballistic missiles fired on Soviet territory. It was greatly expanded as the test site for innumerable Soviet intermediate and short range missile projects in the 1950's.. Kapustin Year was also headquarters of the first operational R-1/R-2 units, 1950-1953, and later a base for 12 operational R-14 missile launchers. Kapustin Yar was known to have been used for over 3519 major launches from 1946 to 2007. More...
  • Plesetsk Plesetsk was the Soviet Union's northern cosmodrome, used for polar orbit launches of mainly military satellites, and was at one time the busiest launch centre in the world. The collapse of the Soviet Union put the main launch site of Baikonur in Kazakh territory. It now seems that once the Proton rocket is retired, Baikonur will be abandoned and Plesetsk will be Russia's primary launch centre. Upgrades to existing launch facilities will allow advanced versions of the Soyuz rocket and the new Angara launch vehicle to be launched from Plesetsk. Plesetsk's major drawback was the lower net payload in geosynchronous orbit from a northern latitude launch site. However Russia is planning to remove the disadvantage by looping geosynchronous satellites around the moon, using lunar gravity to make the necessary orbital plane change. More...
