China Building World’s First Drone ‘Mothership’

China is constructing the world’s first specialized drone carrier dedicated to launching massive uncrewed underwater vehicles (UUVs) at the Hudong-Zhonghua Shipyard in Shanghai. Details of this covert project emerged through satellite imagery captured by the US defense intelligence agency Vantor, highlighting a major evolution in underwater warfare. Built with strict secrecy, the vessel features a distinct internal hangar and specialized hatchway absent in conventional research or commercial ships, directly signifying its intended military capabilities.

The primary function of this mothership is to deploy multiple large-scale autonomous submarines simultaneously into strategic oceanic operations. Independent underwater warfare expert Mr. H. I. Sutton told the defense news outlet Naval News that, based on its size and structure, the ship is estimated to accommodate at least four Extra-Large Unmanned Underwater Vehicles (XLUUVs). This specialized setup provides Beijing with unprecedented flexibility in maintaining continuous surveillance and long-range force projection.

These Chinese uncrewed submarines are significantly larger than standard drones, ranging between 115 and 148 feet in length, making them six to eight times larger than the US Navy’s 51-foot Orca XLUUV. Capable of executing continuous reconnaissance and launching heavy torpedo strikes across expansive ranges reaching up to 10,000 nautical miles, these massive assets vastly increase China’s strike potential. Operating in tandem with the mothership, the fleet forms an advanced sub-surface operational network.

This development aligns directly with Beijing’s effort to solidify control over the South China Sea and the Taiwan Strait, backed by President Xi Jinping’s repeated pledges to integrate Taiwan, forcibly if necessary. Backed by a shipbuilding capacity nearly 200 times that of the United States and an active fleet exceeding 400 warships, China’s new naval platform presents serious strategic challenges. Western military analysts express deep concern that deploying these uncrewed motherships could decisively alter maritime power dynamics.
