Characteristics

The Topol-M is a cold-launched, three-stage, solid-propellant, silo-based or road-mobile

. The missile's length is 22.7 meters and the first stage has a body diameter of 1.9 meters. The mass at launch is 47,200 kg, including the 1,200 kg payload. Topol-M carries a single

yield 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. It is claimed to have the highest accuracy of any Russian ICBM. The body of the rocket is made by winding carbon fiber. The Topol-M may be deployed either inside a reinforced

. The designation for the silo-based Topol-M missile is believed to be RS-12M2, while the mobile version is RS-12M1. 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. 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.

Development and deployment

The development of the missile began in the late 1980s as a response to the American

Strategic Defense Initiative The Strategic Defense Initiative (SDI) was a proposed missile defense system intended to protect the United States from attack by ballistic nuclear missiles. The program was announced in 1983, by President Ronald Reagan. Reagan called for a ...

. Initially an evolutionary upgrade of the RT-2PM Topol, the missile was redesigned in 1992. The missile's principal designer was Yuri Solomonov, who would later oversee the development of the

. The first flight test took place on December 20, 1994, during which the missile, launched from Plesetsk, hit its target away. Two missiles were put on experimental combat duty in December 1997 at Tatishchevo. The fifth test flight on 22 October 1998 was unsuccessful as the missile exploded after being launched; the sixth test flight two months later was successful.

, introduced 10 missiles into service on 30 December 1998; another ten entered service with a second regiment in December 1999. Silo launcher Topol-M entered service by presidential decree on 13 July 2000, the third, fourth and fifth regiments entered service in 2000, 2003, and 2005. The last regiment was to arrive in 2012. On December 12, 2006, the first three mobile Topol-M missile systems entered duty with a missile unit stationed near the town of Teykovo. Current Strategic Rocket Forces Order of Battle lists the following sites with Topol-M missiles: * 27th Guards Rocket 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 and 20 years.

system. It is said to be capable of making evasive maneuvers to avoid a kill by interceptors, and carries targeting countermeasures and decoys. 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. According to ''

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 Yars. 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.
