A Russian navy attempt to test a feared nuclear-powered torpedo called Poseidon is believed to have failed due to technical problems, it is reported.
Unveiled with much fanfare in 2019, the Poseidon torpedo was said to be able to wipe out cities by causing a tsunami.
But the apocalyptic weapon, launched from the Belgorod, the world’s longest submarine, appears to be going through prolonged technical problems since coming into service last summer.
