Satellite imagery reveals China's construction of a potential first-of-its-kind mothership for extra-extra-large uncrewed underwater vehicles (XXLUUVs) at the Hudong-Zhonghua shipyard in Shanghai. The vessel, approximately 200 meters long, features a large internal hangar capable of accommodating up to four autonomous submersibles and an open-bottom stern well-deck fitted with a 12-arm lifting cradle for launching and recovering the drones. Designed around XXLUUVs up to 45 meters long, these submarine-sized autonomous drones could potentially have a range of around 10,000 nautical miles. The dedicated mothership would enable mobile deployment, recovery, and maintenance of the XXLUUVs far from shore, transforming them from an experimental system into a long-range operational asset.
