The second HMS Louis (K515) was a British Captain-class frigate of the Royal Navy in commission during World War II. Originally constructed as the United States Navy Evarts-class destroyer escort DE-517, she served in the Royal Navy from 1943 to 1946.

Construction and transfer

The ship was laid down by the Boston Navy Yard in Boston, Massachusetts, on 9 July 1943 as the unnamed U.S. Navy destroyer escort DE-517 and launched on 13 August 1943. The United States transferred the ship to the United Kingdom under Lend-Lease on 9 November 1943.

Service history

The ship was commissioned into service in the Royal Navy as HMS Louis (K515) on 9 November 1943 simultaneously with her transfer. She served on antisubmarine patrol and convoy escort duty in the Bay of Biscay, North Atlantic Ocean, and Arctic Ocean. On 24 August 1944, she sank the German submarine U-445 with depth charges in the Bay of Biscay west of St. Nazaire, France, at position 47°21′00″N 005°50′00″W.

The Royal Navy returned Louis to the U.S. Navy at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, on 20 March 1946.

Disposal

The United States Government sold Louis to the Commonwealth of Pennsylvania on 17 June 1946.
