In further efforts to assist in bringing the damaged ship to port, he labored continuously for twelve hours after the cessation of the action.

Swenning was laid down on 17 July 1943 by the Brown Shipbuilding Co., Houston, Texas; launched on 13 September 1943; sponsored by Miss Hertha Rhode; and commissioned on 1 December 1943.

Swenning moved to Galveston, Texas, to complete fitting out and sailed from there on the 28th en route to Bermuda on her shakedown cruise.

The cruise ended at Charleston, South Carolina, where the ship entered the navy yard for a post-shakedown availability period.

The group replenished at Trinidad on 12 April and sailed to Norfolk where the escorts were detached to proceed to New York for yard availability.

After a short training period at Bermuda, the group began offensive patrols in the North Atlantic, mainly off the Grand Banks area of Newfoundland.

Swenning participated in antisubmarine training off Bermuda with Bogue and CortDiv 51 from 23 October to 21 November and from 26 December 1944 to 16 January 1945.

The escort spent February conducting antisubmarine and gunnery exercises at Casco Bay and March training submarines at New London.

She began her last Atlantic war patrol on 16 April when CortDiv 51 joined Bogue to form TG 22.3 at Melville, Rhode Island.

Swenning had no significant role in the ensuing action, but the barrier patrols sank five submarines at the expense of one destroyer escort sunk by a torpedo.

Swenning steamed to Boston, Massachusetts, and entered the navy yard for an overhaul in preparation for duty in the Pacific.

Swenning was struck from the Navy list on 1 July 1972 and sold to Northern Metals Co., Philadelphia, Pennsylvania, for scrap on 17 January 1974.
