HMS Narwhal was an Admiralty M-class destroyer built for the Royal Navy during World War I, launched on 30 December 1915. The M-class was an improved variant of the earlier L-class, designed to reach higher speeds of up to 36 knots, although the actual achieved speed was approximately 34.25 knots during trials. The vessel measured 265 feet (80.8 meters) in length between perpendiculars, with a beam of 26 feet 8 inches (8.1 meters) and a draught of 9 feet 3 inches (2.8 meters). Displacing around 994 long tons (1,010 tons) normally and up to 1,025 long tons (1,041 tons) at full load, the ship was powered by three Yarrow boilers feeding Parsons steam turbines rated at 25,000 shaft horsepower, driving three shafts. HMS Narwhal's armament comprised three single QF 4-inch (100 mm) Mk IV guns positioned along the centerline—one on the forecastle, one aft on a raised platform, and one amidships—along with two single QF 2-pounder (40 mm) anti-aircraft guns. The ship was equipped with two twin rotating torpedo mounts for 21-inch torpedoes and carried a crew of 76 officers and ratings. Constructed by William Denny and Brothers of Dumbarton, the vessel was laid down on 21 April 1915 and completed by March 1916. As part of the Grand Fleet, HMS Narwhal joined the Twelfth Destroyer Flotilla. It participated in the Battle of Jutland (31 May – 1 June 1916), where it launched two torpedoes that missed the German High Seas Fleet. Post-battle, Narwhal was stationed at Cobh, Ireland, conducting anti-submarine and convoy escort duties. Notably, in February 1917, it rescued the crew of the sunken Q-ship HMS Farnborough after being sunk by U-83 and also thwarted U-50's attack on the merchant Cameronia. The vessel was transferred to Devonport in 1918 and joined the Fourth Destroyer Flotilla. After the war, HMS Narwhal stayed at Devonport, but was damaged in a collision in 1919 and was subsequently broken up in 1920. Its service history highlights its role in key naval engagements and anti-submarine operations during WWI, emphasizing its contribution to British naval efforts in the North Atlantic and Irish waters.
