Ghost Fleet Overlord is a fleet of test unmanned surface vehicles operated by the U.S. Navy.[1]
Ghost Fleet Overlord is being developed by the Department of Defense’s Strategic Capabilities Office.[1] It is a partnership between the Defense Department's Strategic Capabilities Office and the Navy.[2]
As of January 2024, the fleet consists of four ships delivered. The first is USV Ranger,[3] the second is USV Nomad,[1] the third is USV Mariner,[4] and the fourth is USV Vanguard, launched on January 15, 2024.[5]
While technically "uncrewed", the ships carry a crew of six human sailors. Most of the ship's functions are automated, but can be carried out manually by the onboard human crew if the need arises.[6]
USV Mariner is outfitted with next-generation command and control systems and a virtualised Aegis Combat System.[7] Its test will help in putting combat systems on Large Unmanned Surface Vehicles.[8]
