The RT-20P was an experimental intercontinental ballistic missile (ICBM) developed but not deployed by the Soviet Union during the Cold War. The control system for it was designed at NPO "Electropribor" (Kharkiv, Ukraine). It was assigned the NATO reporting name SS-15 Scrooge and carried the GRAU index 8K99. The RT-20 was the first mobile ICBM designed by the Soviet Union. Its launch platform was based on the T-10 tank.
