Quick Summary

Satellite images reveal an unusual vessel under construction in a Shanghai shipyard, which analysts suggest may serve as a mothership for large uncrewed submarines. This capability would allow China to deploy these drones over long distances and for extended periods. A military imagery analyst confirmed the presence of a launch-and-recovery system on the vessel based on September 10 satellite imagery.

Story summary

China is constructing what appears to be the world's first underwater mothership capable of launching submarine drones at a shipyard in Shanghai. New satellite images from Vantor, a US defense intelligence company, reveal a red vessel under construction at the Hudong-Zhonghua shipyard, which Beijing has previously used for building large amphibious assault warships. This new mothership is thought to be designed to carry and deploy four of China's newly coined XXLUUVs (extra-extra-large uncrewed underwater vehicles) across vast ocean distances. According to H I Sutton, an independent defense expert specializing in underwater warfare, the ship could potentially house at least four XXLUUVs for extended operations. This development marks a significant advancement as China is currently the only known nation to have designed such large unmanned submarines. If confirmed, this capability would allow Beijing to extend its submarine drone operations far beyond its coastal waters for sustained periods.

🔮 US warns China is expanding its space toolkit with spaceplane and energy weapons While Beijing says it opposes space militarisation, US intelligence warns it could deploy orbital weapons by decade’s end A spaceplane is a spacecraft designed to operate in orbit and return to Earth through the atmosphere, much like the US Space Shuttle, although China’s secretive vehicle is believed to be uncrewed and more closely resembles the smaller American X-37B.
