SS-25 Development
The SS-25 entered development in 1977, with flight tests occurring in between 1983-87. The missile was officially commissioned into service 1988, with 288 missiles deployed at nine sites by 1991. Production is believed to have ceased in 1994, with a total of 450 SS-25 missiles have been built. 2 As of 2013, there were approximately 150 missiles in operational status. 3
Specifications
The SS-25 can deliver a payload of 1,000 kg, with a single warhead, to a range of 11,000 km. 4 The warhead uses a Post-Boost Vehicle (PBV) system, which grants higher accuracy to its single warhead. 5 The system uses a digital computer controlled inertial navigation system which provides an accuracy of 900 m CEP, and is cold-launched from a canister on a wheeled Transporter-Erector-Launcher (TEL) vehicle. 6
Service History
The SS-25 is undergoing a phased retirement as part of Russia’s nuclear modernization program. The missile is being replaced by the SS-27 “Topol-M” ICBM. As of 2016, Russia deploys an estimated 90 SS-25 launchers. 7 At its current rate of retirement, SS-25 will likely be completely out of service in the 2022 timeframe.
