The RS-24 Yars: Russia's Mobile Nuclear Shield

The RS-24 Yars (NATO reporting name: SS-27 Mod 2) is a Russian intercontinental ballistic missile (ICBM) developed by the Moscow Institute of Thermal Technology. Officially entering service in 2010, the Yars was designed as a modern replacement for aging Soviet-era missiles like the R-36 and UR-100N, and as an enhancement of the single-warhead Topol-M . Its primary purpose is to serve as a key component of Russia's nuclear triad, ensuring a credible retaliatory strike capability in the face of potential aggression .

The Yars is a three-stage, solid-fuel missile, which offers significant tactical advantages over older liquid-fuel systems. Solid fuel allows for faster launch preparation—reported to be as little as seven minutes—and enhances the safety and mobility of the system . The missile has a launch weight of approximately 49 tons and a length of about 21 meters . It is capable of delivering a payload of up to 1.2 tons over a distance of up to 12,000 kilometers, giving it the range to strike targets across North America and Europe .

Multiple Independently Targetable Reentry Vehicle (MIRV) Capability

The defining feature of the RS-24 is its MIRV capability, which distinguishes it from its predecessor, the Topol-M. Depending on the source and specific configuration, a single Yars missile can carry between 3 and 6 independently targetable nuclear warheads . Each warhead has an estimated yield of 150 to 500 kilotons, making them significantly more powerful than the atomic bomb dropped on Hiroshima. The MIRV design allows one missile to strike multiple targets simultaneously, overwhelming enemy defenses .

To ensure penetration of advanced missile defense systems (such as the U.S. Ground-Based Midcourse Defense system), the Yars is equipped with a suite of countermeasures. These include active and passive decoys, electronic jamming technology, and the ability to perform evasive maneuvers during its flight trajectory . In its terminal phase, the missile is reported to reach hypersonic speeds exceeding Mach 20 (approximately 24,500 km/h), drastically reducing the time available for interception .

The Yars system is unique in its dual deployment capability. It can be launched from a silo, similar to traditional ICBMs, or from a mobile, road-mobile Transporter-Erector-Launcher (TEL). The mobile version is mounted on a 16x16 wheeled chassis (specifically a MZKT-79221), allowing it to patrol vast, remote areas and launch from virtually any location . This high mobility makes it extremely difficult for adversaries to track and destroy the missiles in a preemptive "first strike," significantly boosting Russia's nuclear deterrent's survivability .

As of 2024, the RS-24 Yars is the most numerous ICBM in the Russian arsenal, accounting for a substantial portion of the ground-based nuclear forces. The Russian military continues to conduct regular training exercises and combat patrols with the Yars, particularly in regions like Siberia, to test its operational readiness and stealth capabilities
