Ghost Fleet Overlord USV participates in ‘Dawn Blitz' exercise 19 January 2021 by Richard Scott An experimental Ghost Fleet Overlord unmanned surface vehicle (USV) has participated in a major amphibious exercise on the US Pacific coast, having previously transited over 4,700 n miles almost entirely autonomously. Developed under a partnership between the US Department of Defense (DoD) and the US Navy (USN) through the Office of the Secretary of Defense’s Strategic Capabilities Office (SCO), the Overlord initiative is a joint programme designed to accelerate navy efforts to develop USVs and demonstrate increasingly capable autonomous behaviours. Outputs from the programme are informing the USN’s Large Unmanned Surface Vehicle (LUSV) acquisition effort.
