Hazelwood was laid down 11 April 1942 by the Bethlehem Shipbuilding Co., San Francisco, California; launched 20 November 1942; sponsored by Mrs. Harold J. Fosdick; and commissioned 18 June 1943.
As the war in the Pacific gained momentum, Hazelwood sortied from Pearl Harbor 22 January 1944 as part of Task Force 52 under Admiral Spruance for the invasion of Kwajalein and Majuro Atolls in the Marshall Islands.
As the 1st Marine Division landed on Peleliu, Palau Islands, 15 September, she pounded enemy shore positions with gunfire to lessen Japanese opposition.
The next week brought constant enemy air raids and a succession of far reaching fleet moves as the Imperial Navy made one final but futile effort to drive America out of the Philippines and regain some measure of control over the seas.
Carrying the war home to the enemy, the carriers launched heavy air raids against Japanese positions in the Ryukyu Islands, Taiwan, Okinawa, and along the China coast 3–7 January 1945.
Swiftly shifting positions as only sea-based power can, the fleet then sped south to provide support for the landings on Iwo Jima, begun 19 February.
Although under constant attack from kamikazes as well as fighters and dive-bombers, Hazelwood came through the invasion untouched and on the night of 25 February sank two small enemy freighters with her guns.
She reached Tokyo 12 January 1954, via Pearl Harbor and spent the next few months operating with a fast carrier task force and patrolling along the Korean coast to enforce an uneasy armistice.
During the Suez Crisis in the fall of 1956 she served with the mighty 6th Fleet, patrolling the eastern Mediterranean and helping to stabilize a tense international situation.
Hazelwood provided on board testing facilities, and helped make possible the perfection of DASH, an advanced and vital ASW weapons system.
Hazelwood arrived Guantanamo Naval Base 5 November, just after the quarantine of Cuba had gone into effect and remained on guard during the crisis, serving as a Gun Fire Support Ship for Task Force 84.
When the nuclear submarine Thresher failed to surface 10 April 1963, Hazelwood immediately deployed to the scene of the tragedy with scientists from the Woods Hole Oceanographic Institution to begin a systematic search for the missing ship.
Hazelwood resumed testing of DASH during June and later in the year conducted on board trials of the Shipboard Landing Assist Device (SLAD).
