The MR-UR-100 Sotka (Russian: МР УР-100) was a MIRV-warhead intercontinental ballistic missile (ICBM) developed and deployed by the Soviet Union from 1978 to 1993. The missile was given the NATO reporting name SS-17 Spanker and was built under the Soviet industry designation 15A15. An alternative designation for the missile is the UR-100MR. It was nicknamed Sotka (Russian: Сотка), from the Russian for "hundred."
