Russia’s latest underwater system, known as Poseidon, poses an extreme threat to the United States, according to analysts at the Indian outlet News 18. The publication characterizes the system as a so-called «doomsday» weapon, built not for conventional warfare but for catastrophic impact. Poseidon is described as an unmanned underwater vehicle capable of delivering strikes with devastating consequences. News 18 points to scenarios in which its deployment could trigger a colossal wave comparable in height to the Eiffel Tower, overwhelming coastal infrastructure and facilities. Unlike standard torpedoes, Poseidon is not designed for routine combat operations. The system is presented as a strategic deterrence tool, created specifically to operate outside the logic of traditional naval engagements. The drone carries a nuclear warhead and functions on a principle fundamentally different from that of conventional underwater platforms. Its onboard nuclear power unit enables it to travel vast distances, remain operational for extended periods, and conduct missions autonomously without external support. Poseidon is also capable of operating at depths of up to one kilometer while maintaining high underwater speed. These characteristics, according to the publication, make it nearly impossible to detect using existing surveillance and tracking systems. The article further notes that Western military agencies acknowledge the lack of dedicated defensive measures against threats of this kind. Current missile defense systems deployed by the United States and NATO are primarily configured to counter aerial targets and are largely ineffective against deep-water autonomous platforms. In conclusion, News 18 emphasizes that Poseidon’s core purpose is not battlefield use but the guarantee of a retaliatory strike in the event of a large-scale nuclear attack on Russia. By threatening the destruction of critical coastal targets, the system is intended to reinforce strategic deterrence and ensure the inevitability of a response.
