A Russian engineer has revealed that Moscow is developing an underwater nuke designed to swamp coastal cities with huge radioactive tsunamis and kill millions of people.
This doomsday weapon is inspired by the experimental Soviet T-15 nuclear torpedo, which was dreamed up by the nuclear physicist Andrei Sakharov but never put into active service. If the T-15 had been built and unleashed it would produce a wave capable of washing a city like London or New York off the map and turning surrounding areas into an irradiated death zone.
Shamil Aliev, a top Russian torpedo designer, has confirmed plans for a WMD which can ‘destroy coastal targets via aquatic explosion’ are currently under review.
