Navy Large Unmanned Surface and Undersea Vehicles: Background and Issues for Congress [Updated May 11, 2022] [open pdf - 2MB]
From the Introduction: "This report provides background information and potential issues for Congress for three types of large unmanned vehicles (UVs) that the Navy wants to develop and procure in FY2023 and beyond:  Large Unmanned Surface Vehicles (LUSVs);  Medium Unmanned Surface Vehicles (MUSVs); and  Extra-large Unmanned Undersea Vehicles (XLUUVs). The Navy wants to acquire these large UVs as part of an effort to shift the Navy to a more distributed fleet architecture, meaning a mix of ships that spreads the Navy's capabilities over an increased number of platforms and avoids concentrating a large portion of the fleet's overall capability into a relatively small number of high-value ships (i.e., a mix of ships that avoids 'putting too many eggs into one basket'). The Navy's proposed FY2023 budget requests $549.3 million in research and development funding for these large UVs and LUSV/MUSV-enabling technologies, and $60.7 million in additional funding for core technologies for XLUUV and other Navy UUVs [Unmanned Undersea Vehicles]. The issue for Congress is whether to approve, reject, or modify the Navy's acquisition strategies and funding requests for these large UVs. The Navy's proposals for developing and procuring them pose a number of oversight issues for Congress. Congress's decisions on these issues could substantially affect Navy capabilities and funding requirements and the shipbuilding and UV industrial bases."
