Apr. 5, 2021 5:13 PM Russia’s military is reportedly engaged in an "unprecedented build up in the Arctic" and is testing its newest "super weapons" - including the Poseidon 2M39 torpedo. CNN reports that Russia’s activity in the Arctic is geared toward taking advantage of less ice in the region by “securing its northern coast and opening up a key shipping route from Asia to Europe.” Russian President Vladimir Putin had said in February the torpedo was in a "key stage" of testing and was expecting more tests in the near future as it nears completion. CNN notes the unmanned stealth torpedo is “powered by a nuclear reactor and intended by Russian designers to sneak past coastal defenses - like those of the U.S. - on the sea floor.”
