What is Russia's Burevestnik missile?
- The 9M730 Burevestnik, whose name translates as "storm petrel", is a ground-launched, low-flying cruise missile that is not only capable of carrying a nuclear warhead but is also nuclear-powered. NATO refers to it as the SSC-X-9 Skyfall.
- Putin, who first revealed the project in March 2018, has said it has an unlimited range and can evade U.S. missile defences. But some Western experts have questioned its strategic value, saying it won't add capabilities that Moscow does not already have, and may disgorge radiation along its flight path.
- Putin said on Sunday that the weapon was unique. Russia's top general, Valery Gerasimov, chief of the general staff of Russia's armed forces, told Putin that in the October 21 test the missile travelled 14,000 km (8,700 miles) and was in the air for about 15 hours. He said it travelled on nuclear power, could defeat any missile defence and has an unlimited range.
