The UR-200 was an intercontinental ballistic missile (ICBM) developed by Vladimir Chelomey's OKB-52 in the Soviet Union.
The design was authorized by the Decisions of the Central Committee of the CPSU of March 16 and August 1, 1961, and the draft project was finished in July[clarification needed] 1962.
The UR-200 was a two-stage liquid-propellant universal ICBM for delivery of replaceable[clarification needed] payloads to the range up to 12000 km, launch of interceptor satellites for space defense, naval recon satellites, and orbital maneuvering warheads.
Unusually for a Soviet missile, the first stage provided attitude control by means of thrust vectoring.
The FOBS, or Fractional Orbital Bombardment System, was a Soviet programme to place a nuclear warhead into a 150 km low Earth orbit, in order to allow the warhead to approach the enemy from any direction, below missile tracking radar systems.
