Description
The UR-200 was a two-stage liquid-propellant universal ICBM for delivery of replaceable payloads to the range up to 12000 km, launch of interceptor satellites for space defense, naval recon satellites, and orbital maneuvering warheads. It was capable of carrying around 3,175 kilograms (7,000 lb) of payload, and could be launched from flat pads, or missile silos built for the R-16 missile. Unusually for a Soviet missile, the first stage provided attitude control by means of thrust vectoring. Nitrogen tetroxide and UDMH were used as propellants.

FOBS
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. The UR-200 was one of several rockets proposed for this purpose, along with the 8K713 and R-36. The use of the UR-200 for FOBS deployment was cancelled in October 1964, when Nikita Khrushchev was removed from power.
Operational history
The UR-200 was never deployed operationally. The successful development of the storable hypergolic-fuelled R-36 silo-launched missile led to the cancellation of the UR-200 in 1965.
