Russia successfully test-fired its Sarmat intercontinental ballistic missile (ICBM), also known as 'Satan II,' on Tuesday, marking a significant step in modernizing its nuclear arsenal. President Vladimir Putin declared the missile the 'most powerful in the world,' stating it would enter combat service by the end of the year. The Sarmat, designed to replace aging Soviet-era Voyevoda missiles, boasts individually targeted warheads with combined power four times greater than Western counterparts, according to Putin.
The test was hailed by Sergei Karakayev, commander of Russia's strategic missile forces, who reported the launch confirmed the missile's intended performance. The Sarmat, weighing 208 tons and capable of reaching speeds of 15,880 mph, is part of Russia's broader nuclear modernization efforts, which include new submarines and bombers. Putin emphasized the missile's role in strategic deterrence, particularly amid tensions with the West over Ukraine.
Background and Context
Russia's nuclear modernization has accelerated since Putin took power in 2000, with hundreds of new land-based ICBMs deployed. The last remaining U.S.-Russia nuclear arms pact expired in February, ending caps on the world's two largest atomic arsenals for the first time in over 50 years. This has raised concerns about an unconstrained nuclear arms race. The U.S. has since launched its own costly modernization of its arsenal.
The Sarmat's development began in 2011, with prior tests yielding mixed results, including a massive explosion during an abortive test in 2024. Despite setbacks, Putin framed the latest test as a success, aligning with his claims that the Ukraine conflict is nearing an end. Meanwhile, the U.S. deployed RC-135S Cobra Ball aircraft to monitor the test, underscoring ongoing military surveillance.
Additional Developments
Alongside the Sarmat, Russia is advancing work on Poseidon and Burevestnik nuclear propulsion systems, with reports indicating these projects are in their final stages. The Sarmat's deployment is expected to enhance Russia's ground-based strategic nuclear forces, according to Karakayev.
The test occurred amid heightened global tensions, with Putin previously brandishing nuclear threats to deter Western support for Ukraine. The absence of heavy weapons in Russia's recent Victory Day parade on Red Square further highlighted shifts in military messaging.
