HMS Dreadnought (1906) was a revolutionary Royal Navy battleship that significantly advanced naval technology and design, transforming naval power dynamics worldwide. Constructed rapidly at HM Dockyard, Portsmouth, her build time was only about 15 months, with her launch on 10 February 1906 marked by a modest ceremony, despite her immense significance. She measured 527 feet in length, had a beam of 82 feet 1 inch, a draught of nearly 30 feet, and displaced approximately 18,120 long tons at normal load. Her hull featured a double bottom and incorporated extensive internal bulkheads for underwater protection. Dreadnought was powered by steam turbines, a first for British battleships, supplied by Babcock & Wilcox boilers, and she achieved a top speed of 21.6 knots during sea trials. Her armament was notable for her uniform main battery: ten 12-inch (305 mm) guns arranged in five twin turrets, allowing her to deliver a powerful broadside of eight guns with a range of up to 16,450 yards. Her secondary armament initially included twenty-seven 3-inch guns for close defense, with later modifications reducing the number of guns as anti-aircraft weapons were added. She also carried five submerged 18-inch torpedo tubes. Her armor was Krupp cemented, with an 11-inch waterline belt and 11-inch thick turret faces, providing formidable protection. The ship featured advanced fire-control systems, including electrically transmitted targeting data, rangefinders, and later, director firing systems, enhancing her gunnery accuracy. Her design was influenced by naval developments and strategic insights, especially from Admiral Fisher, emphasizing speed, uniform heavy armament, and internal protection. Dreadnought served as a flagship in the Home Fleet, participated in significant reviews, and became a symbol of British naval dominance. Her most notable combat action was sinking the German submarine SM U-29 in 1915, making her the only battleship to purposefully destroy a submarine. She missed the Battle of Jutland due to a refit but remained active until she was decommissioned and sold for scrap in 1921. Her legacy was so profound that subsequent battleships were called "dreadnoughts," and her name has been reused for various vessels and even as a symbol in cultural references.
