MOSCOW (Reuters) -Russian President Vladimir Putin said on Wednesday that Russia had tested a Poseidon nuclear-powered super autonomous torpedo and that it had been a great success.

There are few confirmed details about the Poseidon in the public domain but it is essentially an autonomous nuclear-capable torpedo which is capable of triggering radioactive ocean swells to render coastal cities uninhabitable.
