"After President Lyndon B. Johnson ended attacks on most of North Vietnam by U.S. aircraft and naval vessels in March 1968, the Nasty boats were employed for offshore patrols and commando insertions. Three were transferred briefly to the South Vietnamese navy, and six were lost in combat. The surviving units returned to the United States in 1972 and were stricken by 1981. "
