A US Air Force WC-135R Constant Phoenix aircraft, commonly called the nuke sniffer, conducted a nearly 14-hour surveillance flight near Russia’s Arctic nuclear facilities, including the strategic Murmansk region and Novaya Zemlya test sites. This mission aims to detect radioactive emissions linked to Russia’s nuclear-powered cruise missile, the Burevestnik—known to NATO as Skyfall, which President Putin claims has passed final tests and may soon be operational.
