Description
The UR-100N is a fourth-generation silo-launched liquid-propellant ICBM similar to the UR-100 but with much increased dimensions, mass, performance, and payload. The missile was not designed to use existing UR-100 silos, and therefore had new silos constructed for it.
The missile has a preparation time to start of 25 minutes, a storage period of 22 years, and 6 MIRVs.[7]
Operational history
The UR-100N reached initial operating capability in 1974, and by 1978 an inventory of 190 launchers were reached. In 1979, the UR-100UTTKh became operational and by 1983 had replaced many older missiles and reached a maximum inventory of 760 launchers. This had fallen to 500 by 1991, and with the dissolution of the Soviet Union, many in Ukraine became property of that nation. 170 remained in Russia, although treaty obligations required the rearming of the missiles with single warheads. As of 2018, the Strategic Missile Troops had 20 (or more likely just 10) UR-100NUTTKh in active service.[8] Recent political developments have led to rearmament of the missiles with the Avangard hypersonic glide vehicles (HGVs) (NATO designation SS-19 Mod 4)[9][1] On 27 December 2019, the first missile regiment armed with the Avangard HGV officially entered combat duty.[10]

Civil application
The UR-100N forms the basis of the
START I treaty
The START I treaty was signed by the Soviet Union in 1991. The treaty required the Soviet Union to begin the process of dismantling nuclear warheads and the launchers used for UR-100N missiles.[12] The Soviet Union had 300 100NUTTH missiles stationed in both Russia and Ukraine: 130 deployed in Ukraine, and the rest scattered around Russia.[13] After the fall of the USSR, Ukraine claimed ownership of all the missiles locating in its territory. Ukraine then began dismantling launchers for the UR-100N missiles in compliance with the START I treaty. Nuclear warheads that were deployed in Ukraine were also dismantled following terms of the treaty.[14]

- The Armed Forces of Ukraine inherited a number of missiles from the Soviet Union and turned them over to Russia.[16]
After the Budapest Memorandum was signed in 1994, the 43rd Rocket Army shipped more than 1,326 warheads from its nuclear storage depots: 675 warheads in 1994, 477 in 1995 and 174 in 1996. On May 31, 1996, the final train left Ukraine for Russia laden with the last of approximately 1,800 warheads, including more than 400 weapons from the
