The RT-2PM2 «Topol-M» (Russian: РТ-2ПМ2 «Тополь-М», NATO reporting name: SS-27 "Sickle B"[3], other designations: RS-12M1, RS-12M2, formerly incorrectly RT-2UTTKh)[4] is one of the most recent intercontinental ballistic missiles to be deployed by Russia (see RS-24), and the first to be developed after the dissolution of the Soviet Union. It was developed from the RT-2PM Topol mobile intercontinental ballistic missile.

In its Russian designation РТ stands for "ракета твердотопливная", raketa tverdotoplivnaya ("solid fuel rocket"), while УТТХ – for "улучшенные тактико-технические характеристики," uluchshenniye taktiko-tekhnicheskie kharakteristiki ("improved tactical and technical characteristics"). "Topol" (тополь) in Russian means "white poplar". It is designed and produced exclusively by the Moscow Institute of Thermal Technology, and built at the Votkinsk Machine Building Plant.[5][6]


The Topol-M is a cold-launched, three-stage, solid-propellant, silo-based or road-mobile intercontinental ballistic missile.[7] The missile's length is 22.7 m and the first stage has a body diameter of 1.9 m. The mass at launch is 47,200 kg, including the 1,200 kg payload. Topol-M carries a single warhead with an 800 kt yield [2] but the design is compatible with MIRV warheads. According to chief designer Yury Solomonov, the missile can carry four to six warheads along with decoys.[8] Its minimum range is estimated to be 2,000 km and the maximum range 10,500 km.[7] It has three solid rocket stages with inertial, autonomous flight control utilizing an onboard GLONASS receiver.[9][10] It is reputed to have the highest accuracy of any Russian ICBM[11] with a CEP of 200m.[12] The body of the rocket is made by winding carbon fiber.

The Topol-M may be deployed either inside a reinforced missile silo or from an APU launcher mounted on the MZKT-79221 "Universal" 16-wheeled transporter-erector-launcher.[11] This mobile launcher is capable of moving through roadless terrain, and launching a missile from any point along its route. The designation for the silo-based Topol-M missile is believed to be RS-12M2, while the mobile version is RS-12M1.[4]

The first stage has rocket motors developed by the Soyuz Federal Center for Dual-Use Technologies. These give the missile a much higher acceleration than other ICBM types. They enable the missile to accelerate to the speed of 7,320 m/s and to travel a flatter trajectory to distances of up to 10,000 km.[1]

As a solid propellant design, the missile can be maintained on alert for prolonged periods of time and can launch within minutes of being given the order.[8]

Development and deployment

The development of the missile began in the late 1980s as an evolutionary upgrade of the RS-12M Topol (SS-25 'Sickle'),[13] and the missile was redesigned in 1992. The first flight test took place on December 20, 1994. Experimental combat duty with 2 missiles in December 1997, the first regiment with 10 missiles in 30 December 1998, second in 1999. Silo launcher Topol-M entered service by presidential decree in 13 July 2000, the third, fourth and fifth regiments entered service in 2000, 2003 and 2005. The last regiment will arrive in 2012.[14]

On December 12, 2006 the first three mobile Topol-M missile systems entered duty with a missile unit stationed near the town of Teykovo.[15]

By the end of 2010 the Russian Strategic Missile Troops operated 70 Topol-M missile systems including 52 silo-based and 18 mobile systems. A further 8 missiles were to join the Forces by 2011–2012.[16] Current Strategic Rocket Forces Order of Battle lists the following sites with Topol-M missiles:[16][17]

  • 27th Guards Missile Army (HQ: Vladimir)
    • 60th Missile Division at Tatishchevo with 60 silo-based Topol-M
    • 54th Guards Missile Division at Teykovo with 18 mobile Topol-M

The Topol-M missiles have a lifetime between 15 to 20 years.[7]

Missile defense evasion capabilities

According to Russia the missile is designed to be immune to any current or planned U.S. missile defense system.[18] It is claimed to be capable of making evasive maneuvers to avoid a kill by interceptors, and carries targeting countermeasures and decoys.[19]

One of the Topol-M's most notable features is its short engine burn time following take-off, intended to minimize satellite detection of launches and thereby complicate both early warning and interception by missile defense systems during boost phase. The missile also has a relatively flat ballistic trajectory, complicating defense acquisition and interception.[20]

According to The Washington Times, Russia has conducted a successful test of the evasive payload delivery system.[21] The missile was launched on November 1, 2005 from the Kapustin Yar facility. The warhead changed course after separating from the launcher, making it difficult to predict a re-entry trajectory.

Equipment of Topol-M with MIRV

A new missile loosely based on Topol-M and equipped with multiple re-entry vehicles (MIRV) is called RS-24. In January 2009 Russian sources hinted that the production of the mobile Topol-M missile would be shutting down in 2009 and that the new MIRVed RS-24 version would replace it.[22]


As of 2015, the only operator of the Topol-M is Russia's Strategic Rocket Forces, with 78 missiles deployed.[23]

Since 2010 no more Topol-M missiles have been purchased and they are being replaced by the RS-24.[24]
