HMS Seymour (K563) was a Captain-class frigate of the Royal Navy, serving during World War II. Originally constructed as a United States Navy Buckley-class destroyer escort designated DE-98, she was built by Bethlehem-Hingham Shipyard in Hingham, Massachusetts. Laid down on 1 September 1943 and launched on 1 November 1943, the ship was transferred to the United Kingdom upon completion. On 23 December 1943, she was commissioned into Royal Navy service as HMS Seymour (K563), coinciding with her transfer. As a Captain-class frigate, HMS Seymour primarily fulfilled patrol and escort duties throughout the remainder of the war. Her design as a Buckley-class destroyer escort equipped her with the necessary armament and capabilities for anti-submarine warfare, convoy escort, and maritime patrol. Her service was marked by her active participation in protecting Allied shipping routes amid the intense naval conflicts of the Atlantic. A notable event in her service occurred on 1 March 1945, when HMS Seymour sank the German S-boat S-220, a motor torpedo boat, which was known to the Allies as an "E-boat." This engagement underscored her effectiveness in anti-ship warfare during her operational tenure. Following the end of World War II, HMS Seymour was returned to the U.S. Navy on 5 January 1946. She was officially struck from the Naval Vessel Register on 25 February 1946 and was sold for scrapping on 10 December 1946. Her service exemplifies the vital role played by United States-built escort ships transferred to the Royal Navy in the Battle of the Atlantic, contributing significantly to Allied maritime security during the war.
