Russia on Tuesday test-fired a new intercontinental ballistic missile as part of efforts to modernise the country’s nuclear forces, a launch hailed by President Vladimir Putin just days after his claim that the fighting in Ukraine is nearing an end.

Putin said that the nuclear-armed Sarmat missile would enter combat service at the end of the year. It was built to replace the ageing Soviet-built Voyevoda.

“This is the most powerful missile in the world,” Putin declared, adding that the combined power of the Sarmat’s individually targeted warheads is more than four times higher than that of any Western counterpart.

The Russian leader has repeatedly brandished the nuclear sword after sending troops into Ukraine in February 2022 to try to deter the West from ramping up support for Ukraine.

After overseeing a military parade on Red Square on Saturday commemorating the defeat of Nazi Germany in World War II, which for the first time in nearly two decades did not include heavy weapons, Putin declared the conflict in Ukraine was coming to an end.

Since coming to power in 2000, Putin has overseen efforts to upgrade the Soviet-built components of the Russian nuclear triad – deploying hundreds of new, land-based intercontinental ballistic missiles, commissioning new nuclear submarines and modernising nuclear-capable bombers.
