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."

MIT researchers think they've worked out exactly how Russia's Burevestnik nuclear-powered missile flies. "It's almost certainly a terrible idea," one analyst said. "But it's not…

Their modelling found the missile's reactor design is likely to release large amounts of radioactive material in its exhaust.
