HMS Grimsby was a lead ship of the Grimsby-class sloop of the British Royal Navy, constructed during the 1930s and commissioned in 1934. The vessel measured 266 feet 3 inches (81.15 meters) in overall length, with a beam of 36 feet (10.97 meters) and a deep load draught of 9 feet 6 inches (2.90 meters). Its displacement was 990 long tons (1,010 metric tons) at standard load, increasing to 1,355 long tons (1,377 metric tons) at full load. The ship was powered by two geared steam turbines, which drove two shafts and were fueled by two Admiralty 3-drum boilers, producing 2,000 shaft horsepower and enabling a maximum speed of 16.5 knots (30.6 km/h). With a range of 6,000 nautical miles (11,000 km) at 10 knots, HMS Grimsby was well suited for extended escort missions. The armament of HMS Grimsby included two 4.7-inch (120 mm) Mark IX guns mounted fore and aft along the centreline, supplemented by a single QF 3-inch 20 cwt anti-aircraft gun in "B" position, four 3-pounder saluting guns, and eight machine guns. The ship could be configured for minesweeping or minelaying operations, which involved removing the aft 4.7-inch gun to accommodate minesweeping gear. The vessel had a crew complement of 103 officers and men. Laid down on 23 January 1933, launched on 19 July of the same year, and completed by 17 May 1934, HMS Grimsby initially served on the China Station based at Hong Kong, conducting patrols along China's coast to deter piracy. Her duties included periodic refits, notably a major overhaul at Singapore in 1939, after which she transferred to the East Indies Station for operations in the Indian Ocean, Persian Gulf, and Red Sea. The outbreak of World War II saw her return to the UK, where she joined the Rosyth Escort Force, escorting convoys along the British east coast. Subsequently, she was deployed to the Red Sea Escort Force, escorting convoys between Aden and Suez until March 1941. In the Mediterranean, HMS Grimsby participated in convoy escort duties, notably during the evacuation of Greece in April 1941. On 25 May 1941, while escorting a convoy to Tobruk, she was attacked by Italian and German dive bombers. The aircraft sank the tanker Helka and damaged Grimsby, which was later sunk by further dive-bomber attacks, resulting in the loss of eleven crew members. HMS Grimsby’s service exemplifies the vital role of escort vessels in maritime warfare during the early years of WWII.
