Plesetsk LC41/1


R-7 launch complex. Code named 'Lesobaza', this was the first complex completed at Plesetsk, being declared ready for military service with the R-7A ICBM in November 1959. The complex followed the design of the protoype facility built at Area 31 of Baikonur and included its own residential area for military personnel and assembly buildings for launchers and payloads.

The launchers were assembled and integrated with their payload in a horizontal position and transported to the launch pad by the railway. As operational ICBM facilities, the complex consisted of: Launch pad 1; Assembly Hall 142; and Residential Area 41. During the Cuban missile crisis (11 September to 21 November 1962), an R-7A with a live thermonuclear weapon was held in readiness on this pad for launch on the United States with an 8 to 12 hour reaction time from the go order. LC 41 was withdrawn from ICBM service in 1963 and converted to a space launch pad for R-7-derived launch vehicles. The first space launch was on 17 March 1966, and it continued as the only space-launch pad at Plesetsk for this class of booster for serveral years. It continued in service until 1989, when reconstruction began as a pad for launch of the Zenit-2 booster. The collapse of the Soviet Union ended this work (the Zenit-2 being built in the newly-independent Ukraine). Work began in the late 1990's to rebuild it yet again as the launch pad for the new all-Russian Angara booster, but funds for this were a constant problem, leaving completion uncertain.

Associated Launch Vehicles
  • R-7A Russian intercontinental ballistic missile. The R-7A was an improved version of the R-7 first ICBM, and the one actually deployed to pads in Baikonur and Plesetsk. The missile saw service from 1960 to 1968. Four pads at Plesetsk, and one reserve pad at Baikonur, were operational at the peak of deployment in 1962. These were the Soviet Union's only strategic missile deterrent during the Cuban Missile Crisis. More...

  • Soyuz 11A511U Russian standardised man-rated orbital launch vehicle derived from the original R-7 ICBM of 1957. It has been launched in greater numbers than any orbital launch vehicle in history. Not coincidentally, it has been the most reliable as well. After over 40 years service in Russia, ESA built a new launch pad at Kourou which will keep it in service from three launch sites in three countries well into the mid-21st Century. 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...
