HMS Stork (L81) was a Bittern-class sloop of the Royal Navy, constructed by William Denny & Brothers in Dumbarton, Scotland. Laid down on 19 June 1935 and launched on 21 April 1936, she was commissioned later that year on 10 September. The vessel was initially completed as an unarmed survey ship, designed with flexibility for future armament of anti-aircraft and anti-submarine weapons. Her dimensions and specific physical characteristics are not detailed in the source, but her class was intended as a versatile, general-purpose vessel suitable for convoy escort duties. During her service, HMS Stork was actively involved in World War II. She initially operated in Malayan waters before returning to Devonport in early 1939 for refitting, where her main armament and anti-aircraft defenses were installed. By the outbreak of war in September 1939, she was engaged in convoy escort duties along the North Sea and east coast routes. Notably, she participated in the Norwegian Campaign in April 1940, assisting at Narvik and rescuing survivors from the transport MS Chrobry. Stork sustained damage from an air attack in September 1940, leading to six months of repairs. After repairs, she was assigned to the 36th Escort Group under Commander FJ Walker in August 1941, escorting Atlantic and Mediterranean convoys. During this period, she played a significant role in anti-submarine warfare, credited with the destruction of four U-boats—U-131, U-574, U-252, and U-634—through depth charges, ramming, and coordinated attacks. She participated in notable operations such as the sinking of U-634 in August 1943 while escorting convoy SL 135. In November 1942, while supporting Operation Torch off Algeria, HMS Stork was torpedoed by U-77. She was towed for repairs, returning to service later that year. In 1944, she supported Operation Neptune, the Normandy landings, as part of the 116th Escort Group. Plans to transfer her to the Pacific Fleet were halted due to the Japanese surrender, and she was subsequently placed in reserve. Post-war, HMS Stork served in the Fishery Protection Squadron from 1946 to 1948 before being decommissioned and broken up in 1958. Her wartime record, notably her success in anti-submarine warfare, highlights her importance as a convoy escort vessel during critical naval operations in World War II.
