Ukrainian orbital launch vehicle. Modernized version of 63S1 initial configuration of the first Kosmos launcher and the prototype for the production 11K63 launch vehicle. Suborbital launches from Plesetsk from 1965 at from the modified R-12 silo 'Dvina'. Flown only a few times in 1965-1967. Succeeded by the 11K63 production model launched from the 'Raduga' complex.

LEO Payload: 450 kg (990 lb) to a 270 km orbit at 71.00 degrees.

  • 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...
