Russian President Vladimir Putin hails a test launch of Russia’s new nuclear-capable ballistic missile Sarmat, describing it as the “most powerful missile in the world.” Russian state television shows Sergei Karakayev, commander of Russia’s strategic missile forces, reporting to Putin on what he says was a successful test launch. Putin says the missile is set to enter combat duty by the end of the year, with deployment aimed at strengthening Russia’s ground-based strategic nuclear forces. Multiple outlets report that the Sarmat is designed to deliver nuclear warheads over long distances, including targets in the United States or Europe, and that it is intended to overcome missile defence systems. The reporting also notes that the test launch follows years of delays and setbacks in the missile program and references past test difficulties, including a reported launch failure in September 2024. The launches come after key limits on U.S. and Russian nuclear arsenals lapsed, with the New START agreement ending in February, which Western analysts say has increased freedom for both countries in nuclear posture. Western analysts cited in one report question some of the claims about the missile’s capabilities and performance.
