HMS St. Helena (K590) was a Colony-class frigate that served in the Royal Navy during World War II. Originally ordered by the United States Navy as a Tacoma-class patrol frigate with the designation USS Pasley (PF-86), she was constructed by the Walsh-Kaiser Company in Providence, Rhode Island. The vessel was laid down on September 22, 1943, and launched on October 20, 1943. Initially classified as a patrol gunboat (PG-194), she was reclassified as a patrol frigate (PF-86) on April 15, 1943, reflecting her designated role. Before her completion, the ship was transferred to the United Kingdom under the Lend-Lease agreement on February 19, 1944, and was renamed HMS St. Helena (K590). As part of her service in the Royal Navy, she participated in wartime operations during World War II. Her service was relatively brief, ending in 1945, after which she was returned to the U.S. Navy in Norfolk, Virginia, on April 8, 1946. Following her return, she was briefly listed on the Naval Vessel Register as USS St. Helena (PF-86), but was struck from the register on June 19, 1946. Subsequently, she was transferred to the U.S. Maritime Commission on April 1, 1947, and sold to the Sun Shipbuilding and Drydock Company of Chester, Pennsylvania, for scrapping. Her dismantling was completed on October 28, 1947. This vessel's history highlights her role as a wartime patrol frigate, built in the U.S. and transferred to the Royal Navy, exemplifying the collaborative efforts of Allied nations during World War II.
