SEALORDS was an acronym for South East Asian Lake Ocean River Delta Strategy. In February 1969, as part of the Vietnamization program, the United States Navy began handing over to South Vietnam a fleet of almost 250 patrol craft and 500 motorized junks, which had previously been part of the Mobile Riverine Force and Task Forces 116 and 117. The Army of the Republic of Vietnam (ARVN), aided by U.S. naval advisers, took charge of the patrol craft and the program was renamed SEALORDS. Practically all of the craft fell into the hands of the Vietcong and the North Vietnamese in 1975.
