The RS-28 Sarmat (Russian:РС-28 Сармат, [4] named after the Sarmatians; [5] NATO reporting name: SS-X-29 [6] or SS-X-30 [7] ) is a Russian liquid-fueled, MIRV-equipped super-heavy intercontinental ballistic missile (ICBM) under development by the Makeyev Rocket Design Bureau since 2009. [4] [8] It is intended to replace the R-36M ICBM (SS-18 'Satan') in Russia's arsenal. [9] [10]

The Sarmat is one of the six new Russian strategic weapons unveiled by Russian President Vladimir Putin on 1 March 2018. [11] The RS-28 Sarmat is expected to enter service in 2021. [12]

History

In February 2014, a Russian military official announced the Sarmat is expected to be ready for deployment around 2020. [13] In May the same year, another official source suggested that the program was being accelerated and that it would, in his opinion, constitute up to 100 percent of Russia's fixed land-based nuclear arsenal by 2021. [14] [15]

In late June 2015, it was reported that the production schedule for the first prototype of the Sarmat was slipping. [16] [17] The RS-28 Sarmat was expected to become operational in 2016. [18]

On 10 August 2016, Russia successfully tested the RS-28's first-stage engine named PDU-99. [19] The first image of the missile was declassified and unveiled in October 2016.[ citation needed ]

In early 2017, prototype missiles had been reportedly built and delivered to Plesetsk Cosmodrome for trials but the test program was being delayed to re-check key hardware components before initial launch. [20]

According to the commander of the Russian Strategic Forces, Col. Gen. Sergei Karakayev, the RS-28 Sarmat will be deployed with the 13th Red Banner Rocket Division of the 31st Missile Army at Dombarovsky Air Base, Orenburg Oblast and with the 62nd Red Banner Rocket Division of the 33rd Guards Rocket Army at Uzhur, Krasnoyarsk Krai, replacing the previous R-36M ICBMs currently located there. [9]

In late December 2017, the first successful ejection test of the missile was carried out at the Plesetsk Cosmodrome. According to the report, the missile flew several dozen kilometers and fell within the test range. [21] [22]

On 1 March 2018, Russian president Vladimir Putin, in his annual address to the Federal Assembly, said that "the active phase of tests" of the missile had begun. [23] Shortly after, an anonymous military source was cited as saying that the information about the Sarmat missile had in 2007 been leaked to the West deliberately. [24] On 30 March 2018, the Russian Defence Ministry published a video showing the Sarmat performing its second successful test-launch at the Plesetsk Cosmodrome.[ citation needed ]

On 24 December 2019, during the exhibition of the modern weapon systems at the National Defense Management Center, it was reported that Sarmat is capable of a "35,000 km sub-orbital flight". The trials of the missile complex are expected to be completed in 2021, and, during the 2020-2027 period, "twenty missile regiments are planned to be rearmed with the RS-28". [25]

Design

The RS-28 Sarmat will be capable of carrying about 10 tonnes of payload for either up to 10 heavy or 15 light MIRV warheads, [26] an unspecified number of Avangard hypersonic glide vehicles (HGVs) [27] or a combination of warheads and massive amounts of countermeasures against anti-ballistic missile systems. [28] [29] The Russian ministry of Defense said that the missile is Russia's response to the U.S. Prompt Global Strike system. [14]

Sarmat has a short boost phase, which shortens the interval when it can be tracked by satellites with infrared sensors, such as the U.S. Space-Based Infrared System, making it more difficult to intercept. [30] [31] [32] [33] It is speculated that the Sarmat could fly a trajectory over the South Pole, completely immune to any current missile defense system, [31] and that it has the Fractional Orbital Bombardment (FOBS) capability. [9]

According to various sources, RS-28's launch sites are to be equipped with the "Mozyr" [34] active protection system, designed to negate potential adversary's first strike advantage by kinetically destroying incoming bombs, cruise missiles and ICBM warheads at altitudes of up to 6 km.

Intercontinental ballistic missile Ballistic missile with a range of more than 5,500 kilometres

An intercontinental ballistic missile (ICBM) is a missile with a minimum range of 5,500 kilometres (3,400 mi) primarily designed for nuclear weapons delivery. Similarly, conventional, chemical, and biological weapons can also be delivered with varying effectiveness, but have never been deployed on ICBMs. Most modern designs support multiple independently targetable reentry vehicles (MIRVs), allowing a single missile to carry several warheads, each of which can strike a different target. Russia, United States, China, France, India, United Kingdom, and North Korea are the only countries that have operational ICBMs.

Plesetsk Cosmodrome Spaceport in Mirny, Arkhangelsk Oblast, northwestern Russia

Plesetsk Cosmodrome is a Russian spaceport located in Mirny, Arkhangelsk Oblast, about 800 km north of Moscow and approximately 200 km south of Arkhangelsk, the cosmodrome dates from 1957. Originally developed as an ICBM site for the R-7 missile, it also served for numerous satellite launches using the R-7 and other rockets. Its high latitude makes it useful only for certain types of launches, especially the Molniya orbits, so for much of the site's history it functioned as a secondary location, with most orbital launches taking place from Baikonur, in the Kazakh SSR. With the end of the Soviet Union, Baikonur became a foreign territory, and Kazakhstan charged $115 million usage fees annually. Consequently, Plesetsk has seen considerably more activity since the 2000s.

Strategic Rocket Forces Russian military unit

The Strategic Rocket Forces of the Russian Federation or the Strategic Missile Forces of the Russian Federation are a separate-troops branch of the Russian Armed Forces that control Russia's land-based intercontinental ballistic missiles (ICBMs).

RT-2PM2 Topol-M Russian ICBM

R-36 (missile) Type of intercontinental ballistic missile designed by the Soviet Union

The R-36 is a family of intercontinental ballistic missiles (ICBMs) and space launch vehicles (Tsyklon) designed by the Soviet Union during the Cold War. The original R-36 was deployed under the GRAU index 8K67 and was given the NATO reporting name SS-9 Scarp. It was able to carry three warheads and was the first Soviet MRV(multiple reentry vehicle) missile. The later version, the R-36M was produced under the GRAU designations 15A14 and 15A18 and was given the NATO reporting name SS-18 Satan. This missile was viewed by certain United States analysts as giving the Soviet Union first strike advantage over the U.S., particularly because of its rapid silo-reload ability, very heavy throw weight and extremely large number of re-entry vehicles. Some versions of the R-36M were deployed with 10 warheads and up to 40 penetration aids and the missile's high throw-weight made it theoretically capable of carrying more warheads or penetration aids. Contemporary U.S. missiles, such as the Minuteman III, carried up to three warheads at most.

RT-2PM Topol Intercontinental ballistic missile
