The RS-26 Rubezh (Russian: РС-26 Рубеж, meaning frontier or boundary), designated by NATO as SS-X-31,[3] is a Russian solid-fueled intermediate-range ballistic missile with a nuclear warhead, of which the range bracket just barely classifies it as an intercontinental ballistic missile (ICBM). It is equipped with a thermonuclear MIRV or MaRV payload, and is also intended to be capable of carrying the Avangard hypersonic glide vehicle. The RS-26 is based on RS-24 Yars, and constitutes a shorter version of the RS-24 with one fewer stages.[4][5] The development process of the RS-26 has been largely comparable to that of the RSD-10 Pioneer, a shortened derivative of the RT-21 Temp 2S. Deployment of the RS-26 is speculated to have a similar strategic impact as the RSD-10.[6]
