Core was originally classified AVG-13, but was re-classified ACV-13, 20 August 1942; CVE-13, 15 July 1943; CVHE-14, 12 June 1955; CVU-13, 1 July 1958; and AKV-13, 7 May 1959. She was launched 15 May 1942 by Seattle-Tacoma Shipbuilding Corp., Tacoma, Wash., under a Maritime Commission contract; sponsored by Mrs. B. B. Smith, wife of Lieutenant Commander Smith; acquired by the Navy 1 May 1942; and commissioned 10 December 1942, Captain M. R. Greer in command.
Clearing Puget Sound 6 February 1943, Core qualified pilots in carrier operations off San Diego, then sailed on to the east coast, arriving at Norfolk 11 April. She continued to train pilots in Chesapeake Bay until 27 June when she sortied as the nucleus of TG 21.12, a hunter-killer group. Such groups, providing cover for the movement of convoys, made a contribution of great significance to winning the Battle of the Atlantic, and the innovation represented by their formation was a marked advance in antisubmarine warfare. Planes from Core worked in coordination with accompanying destroyers scoring a number of successful attacks. Her planes sank U-487 on 13 July in 27°15' N., 34°18' W., and U-67 on 16 July in 30°05' N., 44° 17' W. One of her escorts, George E. Badger (DD-196) sank U-613 on 23 July in 35°32' N., 28"36' W. Core returned to Norfolk 31 July from a most successful first patrol.
Core's second hunter-killer patrol, from 16 August to 2 September 1943 netted her planes U-86 on 24 August in 27°09' N., 37°03' W., and U-185 the same day in 27°00' N., 37°06' W. Putting to sea again 5 October in TG 21.15, Core's planes sank U-378 on 20 October in 47°40' N,, 28°27' W. She returned to Norfolk 19 November.
Following another hunter-killer patrol from 5 December 1943 to 18 January 1944, Core ferried 56 P-51's and other cargo to Liverpool from 6 February to 9 March. From 3 April to 29 May she operated with TK 21.16 in the central and North Atlantic, then sailed from New York 24 June to ferry 85 Army aircraft to Glasgow, Scotland, returning to Norfolk 20 July. Returning to antisubmarine operations 8 August as CTG 22.4, Core conducted training exercises against newly revealed enemy submarine tactices off Bermuda until 8 October when she returned to Norfolk for an overhaul. After a period qualifying carrier pilots at Quonset Point, she sailed from Norfolk 24 January 1945 to lead her group against weather reporting submarines operating in the North Atlantic but fog and rough weather prevented successful attacks. She sailed from Norfolk 3 April to join a large antisubmarine unit at Guantanamo Bay 7 April. Operating in the central and North Atlantic, the escorts of this group combined to sink U-546 on 24 April in 43°53' N. 40°07' W., after the enemy submarine had torpedoed Frederick C. Davis (DE-136). Core returned to New York 11 May for repairs and replenishment.
Clearing Norfolk 13 June 1945, Core arrived at San Diego 25 June. She carried aircraft and aviation personnel to Pearl Harbor and to Samar, returning 30 August. Until 20 October she sailed between Alameda and Seattle on transport duty then sailed for Yokosuka, Japan, on "Magic Carpet" duty, to return homeward-bound servicemen. She made two such voyages from 20 October 1945 to 18 January 1946. Core was placed out of commission in reserve 4 October 1946 at Port Angeles, Wash. Core received one battle star for World War II service.
