Ngô Quyền
The former "McCulloch" was commissioned into the Republic of Vietnam Navy as the frigate RVNS "Ngô Quyền" (HQ-17), named after Ngô Quyền, who expelled Chinese forces in 938 and founded the first modern Vietnamese state. By mid-July 1972, six other former "Casco"-class cutters had joined her in South Vietnamese service. They were the largest warships in the South Vietnamese inventory, and their 5-inch (127-millimeter) guns were South Vietnam's largest naval guns. "Ngô Quyền" and her sisters fought alongside U.S. Navy ships during the final years of the Vietnam War, operating along the South Vietnamese coast on patrol and coastal interdiction duties and providing gunfire support to South Vietnamese forces ashore.
