MR-UR-100U 15A16


Ukrainian intercontinental ballistic missile. Improved version of the MR-UR-100U loaded into the super-hardened 15P715U universal silo, with a modernised guidance system with better reliability and accuracy.

Development of the MR-UR-100UTTKh (UTTKh = 'Improved Technical-Tactical Characteristics) was authorised on 16 August 1976. The draft project was completed in December of the same year. The variant would use the super-hardened 15P715U universal silo, and have a modernised guidance system with better reliability and accuracy. Trials were conducted from 25 October 1977 to 15 December 1979. The missile was not formally accepted for military service until 1 December 1980. Between 1982 and 1984 the missile had entirely replaced the original MR-UR-100 in all 150 silos. Withdrawal of the missile began only four years later, the missile being replaced by the Topol mobile solid propellant ICBM at Bologoye and those at Kostroma being replaced by train-launched ICBM's. With the collapse of the Soviet Union the manufacturer ended up being in now-independent Ukraine - an unacceptable situation for a strategic weapon. By 1991 only 50 silos at Bologoye remained operational, and they were retired by 1994.

The competing design of Chelomei, the UR-100N, was also put into production when the Soviet hierarchy deadlocked and could not pick one design over the other. More...

It was also universally referred to as Tyuratam by both Soviet military staff and engineers, and the US intelligence agencies. Since the dissolution of the Soviet Union the Russian Federation has insisted on continued use of the old Soviet 'public' name of Baikonur. In its Kazakh (Kazak) version this is rendered Baykonur.
