↑PACIFIC OCEAN (June 22, 2022) - The medium displacement unmanned vessel Sea Hunter transits the Pacific Ocean to participate in Exercise Rim of the Pacific (RIMPAC) 2022. Twenty-six nations, 38 ships, four submarines, more than 170 aircraft and 25,000 personnel are participating in RIMPAC from June 29 to Aug. 4 in and around the Hawaiian Islands and Southern California. The world's largest international maritime exercise, RIMPAC provides a unique training opportunity while fostering and sustaining cooperative relationships among participants critical to ensuring the safety of sea lanes and security on the world's oceans. RIMPAC 2022 is the 28th exercise in the series that began in 1971. (U.S. Navy photo by Mass Communication Specialist 1st Class Tyler R. Fraser)

↑PEARL HARBOR (Oct. 31, 2018) - The medium displacement unmanned surface vehicle (MDUSV) prototype Sea Hunter pulls into Joint Base Pearl Harbor-Hickam, Hawaii, Oct. 31, 2018. Sea Hunter's arrival in Hawaii demonstrates that MDUSVs are capable of deployed blue-water operations, enabling a new class of naval system. Highly autonomous USVs like Sea Hunter are creating a new paradigm for Navy surface forces, as they are capable of carrying a variety of payloads and performing many missions, including independent operations from manned Navy ships.
