RS-24 Yars
The RS-24 Yars (РС-24 Ярс – ракета стратегическая (strategic missile)-modification 24) also known as Topol-MR, NATO reporting name SS-29 or SS-27 Mod 2), is a Russian MIRV-equipped, thermonuclear armed intercontinental ballistic missile first tested on May 29, 2007, after a secret military R&D project.
It is essentially the same missile as the Topol-M except the payload “bus” has been modified to carry multiple independently targetable warheads (MIRV). Each missile is thought to be able to carry up to 4 warheads, although there is uncertainty about what is the maximum capacity.
RS-24 is a missile that is heavier than the current RT-2PM2 Topol-M, and which some reports say can carry up to 10 independently targetable warheads. The 2007 tests were publicized as a response to the missile shield that the United States were planning to deploy in Europe. The RS-24 has been deployed operationally since 2010, with more than 50 launchers operational as of June 2017.
Yars does not appear to be a Russian word but the Slavic root яр (yar) is present, being a bank or steep ravine, consistent with the nomenclature of another newly fielded Russian missile, the RS-26 Rubezh (РС-26 Рубеж) meaning a boundary or outer limit. According to Sergey Karakaev, commander of the Strategic Missile Forces, Yars is an acronym for "Yadernaya Raketa Sderzhivaniya" (Russian: Ядерная ракета сдерживания), meaning "Nuclear Deterrence Rocket".
Asserted by the Russian government as being designed to defeat present and potential anti-missile systems, the ICBM was first tested by a launch from a mobile launcher at the Plesetsk Cosmodrome in northwestern Russia at 11:20 GMT, May 29, 2007, and its test warheads landed on target about 5,750 km (3,573 mi) away at the Kura Test Range in Far Eastern Kamchatka Peninsula.
The second launch from Plesetsk to the Kura Test Range was conducted on December 25, 2007, at 13:10 GMT. It successfully reached its destination. The third successful launch from the Plesetsk space center in northwest Russia was conducted on November 26, 2008, at 13:20 GMT. The missile's multiple re-entry vehicles successfully landed uon targets on the Kura testing range.
It was again tested on December 24, 2013, from the Plesetsk Cosmodrome in northwest Russia. On December 26, 2014, the Strategic Forces conducted a successful launch of an RS-24 Yars missile. The missile was launched from a mobile launcher deployed at the Plesetsk test site. Missile warheads were reported to have successfully reached their targets at the Kura test site in Kamchatka. The launch, which was performed with support of the Air and Space Defense Forces, took place at 11:02 MSK (08:02 UTC). More than 10 successful launches took place between 2012 and 2022. One more launch was conducted on October 25, 2023.
On March 1 and October 29, 2024, and October 22, 2025, the Russian Defense Ministry said it conducted successful combat training launches of RS-24 Yars ICBMs from Plesetsk Cosmodrome in Arkhangelsk.
