Sarmat Development

rs-28 sarmatDesigned as part of Russia’s nuclear modernization effort in order to replace the aging SS-18 Satan ICBM, the RS-28 Sarmat began first-stage testing in 2016. In December 2017, Russia’s military conducted an ejection test which reportedly revealed technical deficiencies with the silo-based launchers.1 On March 30, 2018, Russia released video footage of an apparently successful ejection test, which can assumed took place sometime in late March 2018. The RS-28 was initially planned to enter service in 2018, with all 50 missiles current on order fielded by 2020. This timetable has likely been delayed, however, and initial fielding is now anticipated in the 2020-2021 time-frame.

The Sarmat is similar to its predecessor in appearance and function, but will use upgraded electronics and guidance systems, warhead options, and countermeasures.2

In addition to some capability enhancements, the RS-28 aimed at overcoming obsolescence issues facing much of the Russian ICBM fleet. According to Robert Kelley, a former Department of Energy nuclear weapons expert, “Your iPhone can do thousands of more things than in the 1970s when these systems (the Satan) were first deployed. Many of the clunky electronic circuits of that era no longer exist and nobody knows how to make them anymore… the reliability, flexibility, and confidence in the warheads ability to hit their targets will go way up.”3 The Sarmat, with its new electronics and guidance system is estimated to have a 10 m CEP, which makes it capable of targeting hardened sites like missile silos.4

The Sarmat has a variety of warhead options. The missile is reported by Russian media as being able to carry 10 large warheads, 16 smaller ones, a combination of warheads and countermeasures. It may also be capable of carrying hypersonic boost-glide vehicles.5 6 In total, the yield of a Sarmat’s warheads is around 8 mT.7
