Russia has built the first nuclear warheads for its Poseidon super torpedoes – bragging they are “practically indestructible.” The Poseidon project was unveiled by Russian President Vladimir Putin in 2018, with the Russian President hailing it as a fundamentally new strategic nuclear weapon complete with its own nuclear power source. He boasted: “They are very low noise, have high maneuverability and are practically indestructible for the enemy.”
