"China's Version of the Poseidon Super Unmanned Submarine!" On August 17, 2025, local time, U.S. military expert Sutton said that China has two large underwater unmanned submarines, and the development of the Chinese Navy continues to surprise the outside world, but the progress in the development of underwater unmanned submarines is not yet remarkable. According to Sutton's statement, China is striving to gain a strategic advantage in the field of underwater unmanned vehicle technology. Sutton believes: "Although the Chinese Navy's surface ships are trying to catch up with the more powerful U.S. Navy, in the underwater field, China has invested more money, especially in the development of ultra-large unmanned underwater vehicles, and the research and development speed of the Chinese Navy far exceeds other countries. Most countries have not noticed this!"
Sutton said that since 2022, he has discovered that China is developing underwater unmanned vehicles, among which two models are the largest and the latest. The length of the two Chinese underwater unmanned boats is about 18-20 meters, with a shape similar to torpedoes, using pump-jet propulsion systems. The overall size and shape are similar to Russia's "Poseidon" nuclear torpedo, which is equipped with a nuclear warhead. Sutton believes that the Chinese Navy has the largest XLUUV (unmanned underwater vehicle) program in the world, with at least five models put into use over the years. This U.S. expert believes that unlike Russia's nuclear-powered, the large Chinese unmanned submarines and unmanned underwater vehicles may be lithium batteries, or not nuclear-powered. The U.S. expert believes that multiple Chinese unmanned submarines and unmanned underwater vehicles have been tested in the sea, and they have adopted an X-shaped rudder.
This U.S. expert has said so many words, but it's equivalent to saying nothing. So what are these two super-large unmanned underwater vehicles for? Are they intercontinental unmanned submarines? Or are they similar to Russia's Poseidon, capable of carrying nuclear warheads and conducting nuclear strikes? Or do they have underwater surveillance and strike capabilities, attacking the U.S.-Japan joint fleet upon discovery?
Evidently, our large unmanned submarines will be even more, covering the entire Pacific Ocean, and also covering the Indian Ocean! The Russian Poseidon nuclear-powered submarine with unlimited range can silently lurk anywhere, but we don't know its progress, and there has been no news for a long time. Instead, North Korea and China have both developed their own large unmanned submarines. Moreover, Chinese unmanned underwater vehicles are likely to be nuclear-powered, or even if not, they have nearly infinite power provided by solar energy or new energy sources. The Chinese Navy's future goal is to achieve enhanced strength, practicality, and cost-effectiveness! The continuous expansion of the Chinese Navy continues to surprise the outside world. This is not an accident, it is making the West fear! It can be said that in the future, the Pacific will be ours!
