Russia test-fires Sarmat missile, plans deployment by year-endplans deployment by year-end
Russia successfully test-fired its RS-28 Sarmat intercontinental ballistic missile on Tuesday, with President Vladimir Putin calling it the world's most powerful nuclear weapon.
Putin announced the missile will be deployed operationally by the end of 2026 as part of Russia's broader nuclear modernization effort. The test comes days after Putin claimed fighting in Ukraine is nearing an end and follows the expiration of the New START nuclear treaty in February.
Russian Position
Russia frames the Sarmat test as a necessary modernization of its strategic nuclear forces and a demonstration of military capability. Putin emphasized the missile's power and reliability, positioning the deployment as a strengthening of Russia's deterrent posture in a changing security environment.
International Disarmament Perspective
Analysts at the UN Institute for Disarmament Research noted that while the Sarmat deployment is technically feasible, it will not significantly alter Russia's overall strategic deterrent capacity. The test underscores the destabilizing effect of the New START treaty's expiration, removing verification mechanisms and arms control limits between the world's two largest nuclear powers.
- The RS-28 Sarmat is nicknamed 'Satan 2' by some Western analysts, echoing the Cold War moniker of its predecessor, the SS‑18 Satan ICBM.
- New START was the last remaining major nuclear arms control treaty between the United States and Russia before its expiration in 2026.
- Russia's Sarmat is designed to carry up to 10–15 heavy warheads or a combination of warheads and hypersonic glide vehicles, giving it flexible strike options.
Russia-Ukraine Ceasefire Violations
Russian forces continue striking Ukrainian regions like Kherson and Mykolaiv, wounding civilians including teenagers despite a US-brokered three-day truce from May 9 to 11 that both sides confirmed.
