First Launch: 1977.02.15.
Number: 1 .
DS The DS ('Dnepropetrovsk Sputnik') small satellite bus was developed by Yangel's OKB-586 / KB Yuzhnoye in the Ukraine for launch by the same bureau's Kosmos launch vehicles. They were used for a wide range of military and scientific research; component proving tests; and as radar, ASAT, and ABM targets. More...
Kosmos 3 In 1961 Isayev and Reshetnev developed the Voskhod space launch system on the basis of the R-14 IRBM. The initial version of the two stage rocket was designated Kosmos-1. The first 'Voskhod' launch complex was at Baikonur, a modification of one of the pads at the R-16 ICBM launch complex 41. More...

Kosmos 11K65M Russian orbital launch vehicle. Definitive and prolific production version of satellite launcher based on Yangel R-14 IRBM. After further development at NPO Polyot (Omsk, Chief Designer A S Klinishkov), the modified Kosmos-3M added a restartable second stage with an orientation system. This booster was launched form two 'Cusovaya' launch complexes from 1967. The second stage used low thrust rockets using gas generator output to adjust the final velocity of the stage More...

Associated Launch Sites
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...
