RS-26

The RS-26, codenamed Rubezh or Frontier in English, is new road-mobile solid-propellant intercontinental ballistic missile (ICBM) intended to supplement the RS-24 Yars and Topol-M missiles within the Russian Strategic Forces. The first test launch was carried out at the end of 2013 with the ICBM entry into service expected in the 2015-2016 timeframe. The new missile was developed in secrecy and would be equipped with a new warhead with maneuverability capabilities (MARV) and advanced countermeasures to override missile defenses. It has been dubbed the 'ABM Killer' or 'anti-missile defense killer' and its entry into service is due in 2016. The RS-26 may belong to a new generation of ballistic missiles intended to deliver a warhead that is in fact and hypersonic cruise missile. In early 2016 the RS-26 missile specifications were released having a maximum range of 11,000 kilometers carrying four 300-kiloton warheads. The RS-26 booster stage lasts for five minutes making it hard to detect by the radar systems located in Europe. During the descending trajectory the warheads take a dive, lose altitude and fly following a flat trajectory as a hypersonic cruise missile a few hundred kilometers before reaching the intended target. Apparently, the project was abandoned in the late 2010s or early 2020s. In 2022 the Russian Strategic Forces stated that a new mobile ICBM would be developed in 2023 allowing for launch anywhere from Russia. In April 2024, the Russian Strategic Missile Forces conducted a new test of a road-mobile ICBM. The missile tested might be the RS-26 Rubezh equipped with hypersonic glide vehicles derived from the Avangard warhead. The gliding vehicles delivered may reach a top speed of Mach 20 at 50-100 kilometers or altitude. The Rubezh may be intended to hit targets at ranges between 5,000-11,000 kilometers. It is possible the maximum range may exceed 18,000 kilometers allowing to be launched anywhere from Russia against any target on Earth.
