Putin says Russia tested Poseidon nuclear-capable super torpedo

Putin's statement, which comes three days after he praised a successful test of a new nuclear-powered cruise missile, appears to be another message to US President Donald Trump that Russia is standing firm in its maximalist demands on Ukraine.

Speaking at a meeting with soldiers wounded in Ukraine, Putin said the Poseidon drone was tested while running on nuclear power for the first time Tuesday, describing it as unmatched in speed and depth.

He said the nuclear reactor that powers Poseidon is “100 times smaller” than those on submarines, and the power of its nuclear warhead is “significantly higher than that of our most advanced Sarmat intercontinental ballistic missile.”
