The XLUUV (extra-large underwater drone) design is similar to the U.S. Navy's Boeing Orca. But it features four torpedo tubes, indicating an offensive weapons load. This is something Western designs so far have lacked.
New evidence points to China’s XLUUV (extra-large uncrewed underwater vehicles) being armed with torpedoes. This is a significant leap in this space and, together with a large-scale development program, may be out-pacing the West, H I Sutton of Naval News reports.
Extra large uncrewed underwater vehicles (XLUUVs) are quickly becoming a major trend in naval warfare. Leading navies have initiated programs to develop and explore these. Currently, the U.S. Navy and Royal Navy appear to be in the lead, both inexperimentation and in orders.
