USS Laning (DE-159) was laid down on 23 April 1943 by Norfolk Navy Yard, Norfolk, Virginia; launched on 4 July 1943; sponsored by Mrs. Mabel C. Laning, widow of Rear Admiral Harris Laning; and commissioned on 1 August 1943 at Norfolk.
Following training off the New England coast, Laning arrived Norfolk on 1 April 1944 to resume escort duty for transport and supply convoys. From 3 April to 8 October she made three Atlantic-Mediterranean cruises between Norfolk and Bizerte and back to New York City. While steaming from Algiers to Bizerte on 20 April, she fought off five enemy Junkers Ju 88 medium bombers in a night attack, during which an aerial torpedo passed close aboard her starboard side.
Convoy attacked by U-boats
Departing Tunisia on 1 May, Laning joined the westbound convoy GUS-38. Two days later she assumed a forward screening station after Menges (DE-320) was damaged by an acoustic torpedo, fired by U-371. She maintained station while Allied ships hunted for and sank the U-boat on 4 May in the Gulf of Bougie.
During mid-watch on 5 May her radar detected a surface contact and tracked from a range of 13 to 3 miles. As she closed the contact and prepared to challenge the target, U-967, the submarine submerged at a range of 6,000 yards (5,500 m) and headed for the convoy. Assisted by three other escorts, Laning sought to intercept and destroy the U-boat before she could fire on the convoy. Violent underwater explosions at 0310 and 0345 jarred the searching escorts; and, shortly after the latter explosion, Fechteler (DE-157) was torpedoed in the engine room.
While an unsuccessful search for U-967 (scuttled 19 August at Toulon, France) continued, Laning closed the stricken escort at 0410 and began to rescue survivors, Fechteler broke apart and, during another violent explosion at 0530, sank. Laning completed rescue operations at 0621 and transported 125 survivors to Gibraltar before rejoining the convoy that day.
Converted to an APD
After arriving New York on 8 October, Laning served as a practice torpedo target ship out of New London, Connecticut, from 15 October until 22 November when she steamed to Philadelphia, Pennsylvania. Redesignated APD-55 on 24 November, she completed conversion to a Charles Lawrence-classhigh speed transport on 14 February 1945, and steamed to Norfolk on 21 February to train high-speed transport crews.
After Communist aggression in Korea necessitated a buildup of American naval strength, Laning recommissioned on 6 April 1951 at Green Cove Springs. She steamed to Norfolk 11 to 14 May, and for more than three years she operated along the Atlantic coast from Labrador to the Caribbean. Departing Little Creek, Virginia, on 5 January 1955, she served at San Diego from 23 January to 11 April and returned to the east coast, arriving New York on 29 April.
