RT-2PM Topol

The RT-2PM Topol[3] (Russian: РТ-2ПМ Тополь ("Poplar"); NATO reporting name SS-25 Sickle; GRAU designation: 15Ж58 ("15Zh58"); START I designation: RS-12M Topol)[4] was a mobile intercontinental ballistic missile designed in the Soviet Union and in service with Russia's Strategic Missile Troops. As of 2014, Russia planned to replace all RT-2PM ICBMs with versions of Topol-M.[5] In December 2023, the last Topol regiment was taken off combat duty.[6]

Development[edit]

The three stage solid propellant RT-2PM Topol is an improved mobile ICBM which replaced earlier outdated missile complexes. It emerged from the same line of development as mobile missiles such as the RT-21 Temp 2S and the RSD-10 Pioneer, and was deployed as a replacement for the widely deployed UR-100. The United States considered developing their own road-mobile ICBM called the Midgetman, but the program was canceled with the end of the Cold War.


Development of the RT-2PM was approved on July 19, 1977 and carried out by the Moscow Institute of Thermal Technology headed by Alexander Nadiradze. Flight tests were conducted on the Plesetsk test site from February through December 1985. The main problem that had to be overcome during this period was the development of battle management system. After the first test series was successfully conducted in April 1985, with the first regiment with Topol missiles put on alert in July 1985. Throughout this time work continued on improving the battle management system. The test missile firings were finally completed in December 1987. The first regiment of "Topol" missiles employing a modernized mobile command center (in the area of Irkutsk) were put on alert on May 27, 1988. After Nadiradze's death in 1988 Boris N. Lapygin continued his work on the Topol missile.[1]
