Putin’s nuclear-powered cruise missile Burevestnik decoded; Russian Skyfall a radioactive hazard?

Russia’s nuclear-powered Burevestnik (Skyfall) cruise missile is back in the spotlight after new analysis suggested its propulsion system may release radioactive particles during flight. Researchers examining the missile’s suspected direct-cycle nuclear engine say the weapon could leave a radioactive trail while achieving near-unlimited range. The findings raise fresh questions about the environmental risks, safety concerns and strategic implications of one of Vladimir Putin’s most controversial "super weapons."
