Russia stunned the world by claiming a successful test of Poseidon, a nuclear-powered, nuclear-armed underwater drone-torpedo described by the Kremlin as an 'unstoppable' new weapon capable of demolishing coastal cities. In a statement on Oct. 29, 2025, Vladimir Putin said the device had, for the first time, activated its nuclear propulsion system following a submarine launch. He asserted that the torpedo could travel distances and depths beyond existing defences, warning there was 'nothing like this, nothing able to intercept it'.
The revelation of this fact has impacted the different sectors of government, military analysts, and strategists all at once. The unveiling of Poseidon, as well as the extensive statements connected to it, represents a new level of underwater nuclear power. The situation with Russia, the West, and NATO is getting more and more tense and the underwater weapon's ability to change the naval balance is raising concerns.
