The RS-28 Sarmat (Russian: РС-28 Сармат, named after the Sarmatians; NATO reporting name: SS-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. It was one of six new Russian strategic weapons unveiled by Russian president Vladimir Putin on 1 March 2018.
Development began in 2011 with an expected entry into service of 2018-2020. The program experienced numerous delays and test failures. The first test flight occurred on 20 April 2022. A catastrophic test failure in September 2024 destroyed the Plesetsk Cosmodrome test site and subsequent test launches were performed at the Yasny/Dombarovsky operational base. As of 2026, the missile has not yet entered service.
