US Navy's Orca XLUUV Drone Submarine Completes 1,000-Nautical-Mile Voyage, Faces Program Uncertainty
The US Navy's Orca Extra Large Uncrewed Undersea Vehicle (XLUUV), the largest drone submarine in its fleet, successfully completed a voyage exceeding 1,000 nautical miles in the eastern Pacific in July. This marks the first time an XLUUV-class system has achieved such a long-distance autonomous mission. The Orca is designed for extended endurance, with a maximum range of 6,500 nautical miles, utilizing diesel-electric propulsion and surfacing only for battery recharging. It is equipped for various missions including surveillance, mine warfare, reconnaissance, seabed operations, and expeditionary support, aligning with the Pentagon's strategy to integrate unmanned systems into carrier strike groups. Despite this milestone, the Orca program, which has seen an $885 million investment over eight years, faces significant uncertainty regarding its designation as an official program of record, according to a Government Accountability Office (GAO) report.
