NATO has warned that Vladimir Putin has deployed Russia's K-329 Belgorod nuclear submarine which is a carrier of apocalypse underwater drone Poseidon.
The Russian weapon is a giant nuclear-capable torpedo capable of causing radioactive tsunamis that can lay waste to enemy coastlines.
Russian TV propagandist Dmitry Kiselyov notoriously told viewers that Russia should “plunge Britain into the depths of the sea” with its “underwater robotic drone Poseidon” causing a 1,640ft tsunami.
