UR-100K


Russian intercontinental ballistic missile. The UR-100K was a version of the 8K84M with further improvements in accuracy and capable of delivering three separate (but not independently targeted) re-entry vehicles.

Development of the UR-100K began at the end of the 1960's, with the objective of fielding a version of the 8K84M with further improvements in accuracy but also capable of delivering three separate (but not independently targeted) re-entry vehicles. A two-piece nose fairing separated at the end of the second-stage engine burn to expose the warheads. Pyrotechnic charges then separated the re-entry vehicles, which fell in a triangular patter about 1.5 to 2.0 km around the aim-point. Decoys were mounted on the second stage below the warheads and were deployed after they had separated. American National Security Adviser Kissinger complained in the SALT-1 arms talks that the silos and command points of this version of this missile could not be distinguished by American reconnaissance assets from the single-warhead version. However in practice there were internal differences between the missiles and they could not be interchanged as the Americans claimed. Trials began on 2 February 1971 and were completed on 24 November 1971.

It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
