HMS Rocket was an R-class destroyer built by Scotts Shipbuilding and Engineering Company in Greenock, Scotland. Launched in October 1942 and commissioned in August 1943, she was designed as a War Emergency Programme vessel intended for general duties, including anti-submarine escort missions. The R-class ships measured approximately 358 feet 3 inches in overall length, with a beam of 35 feet 8 inches and a draught of 9 feet 6 inches at mean load, displacing 1,705 long tons standard and up to 2,425 long tons at full load. Her propulsion system comprised two Admiralty 3-drum water-tube boilers feeding Parsons single-reduction geared steam turbines, rated at 40,000 shaft horsepower, enabling a maximum speed of 36 knots. Her armament included four 4.7-inch (120 mm) QF Mk. IX guns, capable of anti-aircraft fire with a 40-degree elevation. For close-in defense, she was equipped with a quadruple 2-pounder pom-pom and eight Oerlikon 20 mm cannons. She also carried two quadruple 21-inch torpedo tubes and had a comprehensive anti-submarine suite with four depth charge mortars, two racks, and a total of 70 depth charges. Radar equipment included a Type 290 air warning radar, a Type 285 gunnery radar, and later a Type 272 surface search radar. Her operational history began with work-up at Scapa Flow, followed by service in Plymouth Command, participating in operations along the Brittany coast and engagements such as the Battle of Sept-Îles, where she contributed to the scuttling of the German torpedo boat Limbourne after the sinking of HMS Charybdis. Notably, she sank the German U-86 submarine with fellow destroyer Tumult east of the Azores on 29 November 1943. Subsequently, HMS Rocket served with the Eastern Fleet based at Trincomalee, participating in operations including the attack on Sabang, shelling coastal targets in Sumatra, and anti-shipping sweeps in the Andaman Sea, sinking several vessels and supporting amphibious operations. Postwar, she returned to Britain in 1945 and was later converted into a Type 15 fast anti-submarine frigate in 1951, with a new pennant number F193. She was involved in training and fleet review celebrations before being placed in reserve multiple times. In 1960, she was recommissioned for service in the Far East with the 6th Frigate Squadron. HMS Rocket was decommissioned in 1962 and ultimately scrapped at Dalmuir in March 1967, ending her distinguished service record.
