HMS Glowworm was a G-class destroyer constructed for the Royal Navy in the mid-1930s, characterized by its displacement of approximately 1,350 long tons at standard load and about 1,883 long tons at deep load. The vessel measured 323 feet in length, with a beam of 33 feet and a draught of 12 feet 5 inches. Powered by Parsons geared steam turbines driving two shafts, she generated a total of 34,000 shaft horsepower, allowing her to reach speeds up to 36 knots. Her propulsion system was fueled by three Admiralty 3-drum water-tube boilers, and her fuel capacity of 470 long tons enabled a range of 5,530 nautical miles at 15 knots. Armament on HMS Glowworm included four 4.7-inch (120 mm) Mark IX guns in single mounts, suitable for surface combat, and two quadruple Mark I mounts for 0.5-inch Vickers machine guns for anti-aircraft defense. She was also equipped with the test quintuple torpedo tube mounts for 21-inch torpedoes, along with a depth charge rail and two throwers, initially carrying 20 depth charges, later increased to 35. Her complement comprised around 137 officers and men. Constructed by John I. Thornycroft and Company at Woolston, Hampshire, she was ordered on 5 March 1934, laid down on 15 August 1934, and launched on 22 July 1935. Completed on 22 January 1936 at a cost of £248,785, excluding armament, HMS Glowworm initially served with the 1st Destroyer Flotilla of the Mediterranean Fleet. During her service, she patrolled Spanish waters during the Spanish Civil War and participated in various escort and patrol duties around the Mediterranean and later in the North Sea. Notably, during the Norwegian campaign in April 1940, HMS Glowworm encountered German destroyers and a cruiser during Operation Weserübung. In a heroic engagement on 8 April 1940, she rammed the German heavy cruiser Admiral Hipper after being severely damaged, breaking her bow and sustaining heavy hits herself. The action resulted in the sinking of Glowworm, with her crew suffering heavy casualties, including the death of her captain, Gerard Roope, who was posthumously awarded the Victoria Cross for his valor. The engagement and sacrifice of HMS Glowworm remain a significant chapter in Royal Navy history, exemplifying bravery and tactical determination in wartime.
