RMS Windsor Castle was a notable ocean liner built for the Union-Castle Line, designed primarily for service between the United Kingdom and South Africa. Construction was originally ordered from Harland & Wolff in 1913, but due to delays caused by World War I, her building was subcontracted to John Brown & Company, leading to her completion in 1922. She was one of the only four-stacked ocean liners constructed for routes other than transatlantic crossings, emphasizing her unique design. The ship measured approximately 661 feet (201 meters) in length initially, with a beam that accommodated her four funnels, two masts, and two propellers. She could reach speeds of up to 18 knots, later increased to 20 knots following a refit. Her gross register tonnage was about 19,141, and her passenger capacity was originally 870 across first, second, and third classes, though this was reduced to 604 after her modifications. Windsor Castle's design featured robust safety measures, including a hull subdivided into twelve watertight compartments and a double bottom, alongside ample lifeboats capable of accommodating her full passenger capacity. Her aesthetic was modernized in the 1930s, with a reduction from four to two funnels, the installation of new boilers, and a more streamlined, raked bow that extended her length slightly. Her maiden voyage commenced in April 1922 from Southampton to Cape Town, establishing her as a key vessel on the England-South Africa route. During her service life, she underwent several refits, which included updates to her appearance and safety features. During World War II, she was requisitioned as a troopship, transporting troops across the Atlantic and Mediterranean. Despite surviving a bombing incident in 1941 where a bomb failed to explode, her wartime service ended when she was torpedoed on 23 March 1943 by a German aircraft off the coast of Algeria. She sank stern first after a lengthy struggle, with only one crew member lost, while over 2,700 troops and nearly 300 crew members were rescued by Allied destroyers. Her sinking marked a significant event in maritime wartime history, emphasizing her role in both commercial and military maritime operations.
