HMS Vanoc was a British V-class destroyer launched in 1917, measuring 312 feet (95.10 meters) in length overall with a beam of 29 feet 6 inches (8.99 meters) and a draught between 10 feet 8 inches (3.25 meters) and approximately 11 feet 7½ inches (3.54 meters) depending on load. Displacing 1,090 long tons (1,110 tonnes) standard and up to 1,490 long tons (1,510 tonnes) at full load, the vessel was powered by three oil-fed Yarrow boilers generating steam at 250 psi, feeding Brown-Curtis geared turbines that produced 27,000 shaft horsepower (20,000 kW). This propulsion enabled HMS Vanoc to reach a maximum design speed of 34 knots, with sea trials recording an average speed of 32.083 knots. Her range was approximately 3,500 nautical miles at 15 knots, carrying 368 long tons of oil. The ship's armament initially included four 4-inch Mk V QF guns, a single 3-inch anti-aircraft gun, and four 21-inch torpedo tubes. She was designed with versatility, capable of being converted into a minelayer, with modifications allowing her to carry up to 66 mines and remove torpedo tubes and some guns for this role. Laid down at John Brown & Company’s Clydebank shipyard on 20 September 1916, she was launched on 14 June 1917 and commissioned on 15 August 1917. HMS Vanoc served actively during both World Wars. In WWI, she participated in destroyer flotillas, convoy escort duties, and minelaying operations, notably laying 965 mines during the conflict. Post-war, she was involved in British Baltic operations during the Russian Civil War. Between the wars, her modifications included replacing torpedo mounts and upgrading her anti-aircraft defenses. During the Spanish Civil War, she patrolled in support of British non-intervention efforts. In WWII, Vanoc was pivotal in convoy escort missions, notably sinking U-100 in March 1941 with her first confirmed radar-guided surface engagement, and assisting in sinking U-99 and U-392. She also participated in evacuations from Norway and France, including the notable Operation Aerial. Her anti-submarine efforts continued in the Atlantic and Mediterranean, where she collaborated with other Royal Navy ships and US aircraft. In January 1945, Vanoc collided with the HMS Computator off Normandy, sinking the trawler. Later that year, she was placed into reserve, sold for scrap in June 1945, and dismantled after mid-1946. HMS Vanoc’s service exemplifies the adaptability and enduring utility of the V-class destroyers through two world wars.
