Russia's development of a nuclear-powered cruise missile, nicknamed the "flying Chernobyl," has raised concerns among Western officials since its announcement in 2018. Recent research suggests that the deployment site of the 9M730 Burevestnik, known as the SSC-X-9 Skyfall to NATO, is near a nuclear warhead storage bunker in Vologda. The production of this missile, which adds little to Russia's already sizable nuclear arsenal, remains a mystery to analysts. Western officials have urged Russia to stop the development of nuclear-powered cruise missiles, which they view as potential threats.
