Two U.S. researchers say they have identified the probable deployment site in Russia of the 9M370 Burevestnik, a new nuclear-powered, nuclear-armed cruise missile touted by President Vladimir Putin as "invincible." Putin has said the weapon - dubbed the SSC-X-9 Skyfall by NATO - has an almost unlimited range and can evade U.S. missile defenses. But some Western experts dispute his claims and the Burevestnik's strategic value, saying it will not add capabilities that Moscow does not already have and risks a radiation-spewing mishap.
