USS Haynsworth (DD-700) was named for Commander William McCall Haynsworth Jr., who commanded the destroyer Ingraham when she was rammed by the oiler Chemung in fog off Nova Scotia on 22 August 1942 and exploded. He was killed with all but a handful of his crew. The new destroyer was launched by Federal Shipbuilding at Kearny on 15 April 1944 and commissioned on 22 June 1944.
In September 1944 she escorted the liner Queen Mary, carrying Winston Churchill, out of New York. She reached Pearl Harbor on 20 October and sailed on 16 December for Ulithi, where she joined Vice Admiral McCain's Task Force 38. For the next three months she screened the fast carriers in strikes on Formosa, Luzon, the China coast and Indochina. On 16 February 1945, in fog off Tokyo, she spotted and sank three Japanese picket boats and took 12 prisoners.
In March she sailed with Task Force 58 for the Okinawa operation, bombarded Minami Daito Shima on 28 March, and frequently helped destroy attacking aircraft after the landings of 1 April. A kamikaze crashed her on 6 April 1945, and she retired to Mare Island by way of Ulithi for repairs. She was a training ship at Treasure Island from 17 July to 5 September 1945.
