Russia said Tuesday it successfully tested a nuclear-capable intercontinental ballistic missile and plans to field the weapon later this year, a move that came as ceasefire efforts in Ukraine appeared increasingly strained.
The country had carried out a successful test of the Sarmat intercontinental ballistic missile, according to comments made during a meeting with Strategic Missile Forces commander Sergei Karakayev featured in a Ukrainian news source.
Russian President Vladimir Putin said the heavy, liquid-fueled missile — capable of carrying nuclear warheads — could enter combat duty by the end of 2026.
The missile test unfolded as diplomatic efforts to halt fighting in Ukraine faltered. A U.S.-brokered ceasefire that briefly reduced some long-range strikes expired this weekend, with Kyiv accusing Moscow of resuming large-scale drone attacks and rejecting proposals to extend the truce. Russia and Ukraine have repeatedly traded accusations of violating temporary ceasefires.
Ukrainian President Volodymyr Zelenskyy said Moscow had “no intention” of ending the war, while reports indicated Washington is exploring potential sanctions relief measures to encourage negotiations.
The Sarmat announcement, although not unexpected, signals Moscow’s continued emphasis on strategic nuclear modernization even as battlefield and diplomatic pressures mount in Ukraine.
