The 9M730 Burevestnik Petrel, or SSC-X9 Skyfall, is a state-of-the-art Russian experimental nuclear-powered cruise missile. The Skyfall is only one of six strategic weapons unveiled by President Vladimir Putin since March of 2018. Although not much is known about it, several sources claim that the missile has virtually unlimited range and lethal capabilities. In August of 2019, the Russian nuclear agency Rosatom confirmed that the release of radiation at the Nyonoksa missile testing site near Severodvinsk was linked to an incident involving a classified missile. The incident became known as the Skyfall accident, as many experts and journalists believe the secret Russian missile was probably involved.
