HMS Snipe (U20) was a modified Black Swan-class sloop of the Royal Navy, constructed during the final years of World War II. Built by William Denny and Brothers in Dumbarton, she was laid down on 21 September 1944, launched on 20 December 1945, and officially commissioned on 9 September 1946. Originally intended to be built under the 1940 Supplemental shipbuilding programme by John Brown & Company, the order was canceled and re-allocated to Denny’s shipyard in 1942, along with her sister ship Sparrow. The vessel measured approximately 299 feet 6 inches in length overall, with a beam of 38 feet 6 inches and a deep load draught of 11 feet 4 inches. Displacement ranged from 1,350 to 1,490 long tons standard, increasing to around 1,880 to 1,950 long tons at deep load, depending on armament. Her propulsion system featured two Admiralty three-drum water-tube boilers powering Parsons geared steam turbines, which drove two shafts, delivering a maximum speed of nearly 20 knots. Armament comprised three twin QF 4-inch Mk XVI dual-purpose guns, suitable for both anti-ship and anti-aircraft roles. Anti-aircraft defenses included two twin and two single 40 mm Bofors guns, while anti-submarine warfare was conducted with a split Hedgehog mortar and 110 depth charges. The crew numbered around 192 officers and ratings. Snipe primarily served on the North America and West Indies Station, where she was involved in various duties, including a notable Antarctic tour in early 1948, supporting British bases and engaging Argentine vessels in the South Shetland Islands. She participated in the Deception Island incident in 1953, when Royal Marines were landed to destroy foreign military bases. Following her active service, Snipe attended the 1953 Coronation Review, then entered reserve at Devonport and later Barry. She was decommissioned and towed to Newport, where she was scrapped by J Cashmore in 1960. Throughout her service, HMS Snipe played a role in post-war maritime patrol, territorial waters enforcement, and Cold War operations, representing the transition of the Black Swan-class sloops into the frigate era.
