RS-28 Sarmat

The RS-28 Sarmat (Russian: РС-28 Сармат, named after the Sarmatians; NATO reporting name: SS-X-29 or SS-X-30), often colloquially referred to as Satan II by media outlets, is a three-stage Russian silo-based, liquid-fueled, HGV-capable and FOBS-capable super-heavy intercontinental ballistic missile (ICBM) produced by the Makeyev Rocket Design Bureau. It is intended to replace the Soviet R-36M ICBM in Russia's arsenal. The Sarmat is one of six new Russian strategic weapons unveiled by Russian president Vladimir Putin on 1 March 2018. The RS-28 Sarmat made its first test flight on 20 April 2022. On 16 August 2022, a state contract was signed for the manufacture and supply of the Sarmat strategic missile system. The missile officially entered operational service in September 2023, as the world's longest range and most powerful extant ICBM system.
