Satellite images and military analysts suggest that China may be constructing the world’s first "mothership" specifically designed to carry large underwater drones. The vessel, spotted at the Hudong-Zhonghua shipyard in Shanghai, is believed to be an amphibious ship capable of carrying at least four of China’s classified extra-extra-large uncrewed underwater vehicles. Two of these drones have been identified: one measuring 115 feet, more than twice the size of the U.S. Navy’s Orca, and another at 148 feet. The ship’s hull is estimated to be around 670 feet long and 88.5 feet wide, with a specialized stern that includes a wet well deck and a cradle that can be lowered into the water using 12 vertical arms. Naval historian H I Sutton described the vessel as a "special drone submarine mothership" based on the satellite imagery analyzed. While the satellite images do not definitively confirm the ship’s purpose, they make it difficult to rule out the possibility that it is intended to carry large uncrewed underwater vehicles. Some experts suggest that the vessel could have an internal hangar to hold four of these top-secret drones, raising questions about the official explanation that it is for civilian or research use. Alessandro Arduino, a defense expert from the Royal United Services Institute, said the evidence is compelling but not conclusive. He noted that the new ship aligns with China’s broader strategy of investing in autonomous systems to complement traditional naval power and reshape how military strength is projected and sustained. China has significantly expanded its naval capabilities in recent years, especially in the South China Sea, a region marked by territorial disputes with several neighboring countries, including the Philippines. Recent confrontations in the area have turned violent. The Chinese uncrewed submarine is likely capable of carrying a payload over 10,000 nautical miles, far exceeding the 6,500 nautical miles of the U.S. Orca. In contrast, the UK’s version, known as XV Excalibur, is only 39 feet long. Aditya Ramanathan of India’s Takshashila Institution called the vessel a "novel type of platform" and noted that no other country has a purpose-built submarine carrier. The ship may still be two to three years from deployment after undergoing sea trials. China has not officially confirmed or denied the construction of the vessel. Unmanned submarines, though smaller in size, can perform critical tasks such as collecting acoustic data on other ships and submarines, which can be used to build extensive databases for identifying future encounters. Ramanathan explained that these submarines could make it harder for countries like India to detect them and could extend the reach of underwater drones, potentially restricting freedom of navigation for adversaries. China claims sovereignty over nearly all islands and reefs in the South China Sea, a claim opposed by the Philippines, Vietnam, Brunei, and Taiwan. In 2016, a tribunal under the UN Convention on the Law of the Sea ruled that China’s claims were illegal, a decision that Beijing has rejected. The South China Sea is also a flashpoint with the United States, which opposes China’s sovereignty claims in the region. Ramanathan emphasized that unmanned vessels enhance China’s ability to dominate the underwater domain, creating a military imbalance for its rivals. China and the U.S. are engaged in an escalating naval race, with Beijing building the world’s largest fleet and Washington focusing on high-tech military superiority. China’s shipbuilding capacity is currently estimated to be at least 200 times that of the U.S. Experts suggest that the future of maritime combat may increasingly resemble drone-heavy warfare rather than traditional naval operations.
