HMS Pasley (K564), originally designated as DE-519, was an Evarts-class Captain-class frigate built for the United States Navy during World War II. Laid down at the Boston Navy Yard on 18 July 1943 and launched on 30 August 1943, the vessel was initially intended as a U.S. destroyer escort before being transferred to the Royal Navy under the Lend-Lease agreement. Before her completion, she was allocated to the UK on 19 October 1943 and was first named Lindsay. To avoid confusion with a Canadian corvette, her name was shortly thereafter changed to Pasley, honoring Admiral Sir Thomas Pasley. The ship was commissioned into Royal Navy service on 20 November 1943, bearing the pennant number K564. As HMS Pasley, she served primarily on patrol and escort duties throughout the remainder of World War II, contributing to Allied efforts to safeguard Atlantic convoys and maritime routes. Her service period was characterized by her role in anti-submarine warfare and safeguarding merchant vessels against Axis threats, although specific notable engagements are not detailed in the provided source. Following the conclusion of hostilities, HMS Pasley was returned to the U.S. Navy in England on 20 August 1945, at which point she was reclassified as USS Pasley (DE-519). She was subsequently transferred to the Philadelphia Navy Yard, where she was decommissioned on 26 October 1945. Her brief post-war career ended when she was struck from the Naval Vessel Register on 16 November 1945, and she was subsequently scrapped. The vessel's significance lies in her role as part of the vital convoy escort fleet that contributed to the Allied victory in the Atlantic theater. As part of the Captain-class frigates, she exemplifies the close Anglo-American naval cooperation during WWII and the crucial function of escort vessels in maintaining maritime security amidst the threats posed by German U-boats.
