The US Navy has designated the Snakehead Large Displacement Unmanned Undersea Vehicle (LDUUV) for accelerated acquisition. Unmanned maritime systems are part of the Littoral Combat ship portfolio, the first class of ship designed from initial construction for unmanned vehicle integration. LDUUVs in the Class III Large category, which the Snakehead is part of, are about 48 inches in diameter. The Snakehead LDUUV is intended to have long-range and high endurance capacity and designed for surface or submarine launch. It will be able to be recovered and stored on littoral combat ships, Virginia-class submarines, and Ohio-class submarines, according to an earlier NAVSEA release.
