Russia says it has carried out a test launch of its RS-28 Sarmat intercontinental ballistic missile from the Plesetsk Cosmodrome, adding to already elevated concerns about strategic stability and arms control. The Defense Ministry described the launch as part of a planned test program.

The Sarmat, a heavy missile designed to carry multiple warheads over long distances, has been presented by Moscow as a key part of its nuclear arsenal. The latest test comes at a time of strained relations between Russia and Western governments, with talks on arms limits under pressure and broader security tensions still unresolved.

Reuters reported that the launch was successful, but the ministry did not provide additional operational details in its statement. Independent verification of the test conditions was not included in the initial announcement.

The event is likely to draw scrutiny from governments tracking nuclear force developments, especially as analysts warn that repeated missile demonstrations can deepen mistrust and complicate efforts to rebuild arms control agreements.
