The Sea Hunter is a 132-foot trimaran of roughly 135 to 145 long tons with about a 10,000-nautical-mile range and 30-to-90-day endurance, originating in DARPA's Anti-Submarine Warfare Continuous Trail Unmanned Vessel program, which awarded Leidos a $59 million design-and-build contract in 2012, with the vessel christened on April 7, 2016 and transferred from DARPA to the Office of Naval Research on February 1, 2018; a second vessel, Seahawk, was built under a $35.5 million ONR contract and delivered on April 7, 2021 incorporating more than 300 lessons learned.

A correction is load-bearing: there is no distinct larger-displacement Sea Hunter II successor, since Sea Hunter II is an informal name for Seahawk, the same-class second vessel, so the registry treats them as two vessels of one MDUSV class rather than implying a heavier successor. Navy procurement targets of 11 vessels by 2027 and more than 30 by 2030 are stated force-structure targets rather than delivered inventory and are cap-flagged as projections, and the carrier-strike-group vessel identity is press attribution the Navy did not officially confirm.","formFactor":"maritime","maturityStage":"production","lifecycleState":"active","supersededByModelId":null,"specs":{"notes":[{"label":"Verified","value":"Leidos (NYSE: LDOS; legacy US defense/IT prime) designs + builds the Sea Hunter-class MDUSV from the DARPA ACTUV program.
