UR-100K

Part of UR-100 Family

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.

AKA: 15A20; 15P884; 8K84K; RS-10M; Sego; SS-11 Mod.3. Status: Retired 1990. First Launch: 1969-01-01. Last Launch: 1990-07-17. Number: 119 . Payload: 1,208 kg (2,663 lb). Gross mass: 50,100 kg (110,400 lb). Height: 18.95 m (62.17 ft). Diameter: 2.00 m (6.50 ft). Span: 2.00 m (6.50 ft). Apogee: 1,000 km (600 mi).

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.
