HMS Barham was a Queen Elizabeth-class battleship constructed for the Royal Navy during the early 1910s. Laid down at John Brown & Company's Clydebank shipyard on 24 February 1913 and launched on 31 December 1914, she was completed in 1915. Measuring 643 feet 9 inches (196.2 meters) in overall length, with a beam of 90 feet 7 inches (27.6 meters) and a deep draught of 33 feet (10.1 meters), she displaced approximately 32,590 long tons (33,113 tonnes) normally, increasing to 33,260 long tons (33,794 tonnes) at deep load. Powered by two Brown-Curtis steam turbines and 24 Yarrow boilers, her engines were rated at 75,000 shaft horsepower, capable of reaching a maximum speed of about 25 knots, although her sea trials in 1916 saw a top speed of 23.91 knots. HMS Barham’s armament included eight 15-inch (381 mm) Mk I guns in four twin turrets, and twelve 6-inch (152 mm) guns along the broadside, complemented by anti-aircraft guns and submerged torpedo tubes. Her armor scheme featured a 13-inch (330 mm) waterline belt, with gun turrets protected by 11 to 13 inches of Krupp cemented armor, and a main conning tower with 13 inches of armor. During her service, she underwent various refits, notably in the early 1930s, which included added anti-aircraft defenses and improved fire-control systems, as well as the installation of a catapult and floatplanes for reconnaissance. HMS Barham participated prominently in the Battle of Jutland in 1916, where she engaged German ships, scored several hits, and suffered multiple attacks herself. Her service in the interwar period saw her acting as flagship of the 1st Battle Squadron and serving in the Atlantic, Mediterranean, and Home Fleets. During WWII, she was involved in several key operations, including the Battle of Dakar, Malta convoy escorts, and the Battle of Cape Matapan, where she helped sink Italian cruisers. On 25 November 1941, while part of the Mediterranean Fleet, HMS Barham was torpedoed by German submarine U-331 off the Egyptian coast. The attack caused her to rapidly capsize and explode, resulting in the loss of 862 crew members. Her sinking was one of the notable maritime events of the war, and she is remembered for her active service and tragic end in combat.
