UR-100N

The UR -100N, also known by the Russian armed forces RS -18 is a Soviet / Russian intercontinental ballistic missile. Your NATO reporting name is SS -19 Stiletto. At the strategic missile forces of Russia are still missiles of this type in use.

History

Development began in 1970. Three years later, the first tests were carried out. The first production missiles were put into service in 1975. A total of approximately 360 rockets of this type were stationed in the newly built silos. The largest number was set up on the territory of modern Russia ( 170 ), followed by Ukraine the second most important location. Russia plans to hold a portion of its UR- 100Ns until about 2030 service. These 35 never stationed UR -100N were used, which Russia has bought from 2002 to 2004 from the Ukraine. Regular test start, the Russian missile forces could increase the service time of the UR -100N on 31 years now. They may be also replaced earlier by the RS -24.

Technology

The UR -100N is a further development of the SS -11 Sego. However, the UR -100N is much larger and more accurate. The length increased to 24 m and the diameter by 25% to 2.5m. As the BR 100 also uses the UR -100N a two-stage liquid fuel rocket engine, which is operated with liquid fuel storable ( UDMH NTO ). Fueled weigh the missiles depending on the version 103-106 tons. The range is for all versions of about 10,000 km. A UR -100N can carry up to 5 tons payload. The Mod Version 1 supports 6 re-entry, each containing a nuclear warhead of 550 kt per TNT equivalent. In the version mod 2, however, a single warhead with a variable explosive yield of 2.5 to 5 MT is used. This version has been tested, whether it has been stationed on the other hand is controversial. The mod 3 (UR - 100NUTTH ) is now stationed variant, also with 6 MIRV per missile. The accuracy was improved compared to the MOD 1, as well as the engines, control and silos. The hit accuracy, depending on the source and version of 250-920 m. According to the START II Treaty, all missiles of the United States and Russia should be fitted only with a warhead. But the contract is not entered into force, and so in early 2014 40 UR- 100NUTTH in Tatischtschewo were still stationed (along with Topol -M).

Decommissioned UR- 100NUTTH be used partly as a civil Rockot launcher and Strela.
