HMS Collingwood was a St Vincent-class dreadnought battleship built for the Royal Navy, launched in 1908 and completed by April 1910. She measured 536 feet (163.4 meters) in length, with a beam of 84 feet 2 inches (25.7 meters), and a standard draught of 28 feet (8.5 meters). Displacing approximately 19,700 long tons (20,000 tons) at normal load and up to 22,800 long tons (23,200 tons) at deep load, she was powered by two Parsons steam turbines rated at 24,500 shaft horsepower, driving four shafts, with steam supplied by eighteen Yarrow boilers. Her designed top speed was 21 knots, although during trials she reached just over 20.6 knots. The ship’s range was about 6,900 nautical miles at 10 knots. Her armament consisted of ten 12-inch (305 mm) Mk XI guns in five twin turrets—three along the centerline and two as wing turrets—and twenty 4-inch (102 mm) secondary guns for anti-torpedo boat defense. Additionally, she had three 18-inch (450 mm) torpedo tubes. Her armor protection included a 10-inch thick Krupp cemented waterline belt, with additional armor on the turrets and decks, designed to withstand hits from contemporary naval artillery. HMS Collingwood’s service was primarily in the North Sea, where she was part of the Home and Grand Fleets, often serving as a flagship. Notably, she participated in the Battle of Jutland in May 1916, where she was positioned in the middle of the battle line and engaged German vessels, damaging a battlecruiser and firing a total of 52 armor-piercing shells. During the battle, she also dodged torpedoes and fired at German ships, including SMS Wiesbaden and SMS Derfflinger. Her involvement in Jutland marked her as a significant element of the Royal Navy’s engagement during World War I. After Jutland, Collingwood continued fleet operations and training exercises, serving as a flagship at times and enduring the evolving demands of wartime naval warfare. Post-war, she was deemed obsolete, relegated to reserve, and used for training purposes. She was finally sold for scrap in 1922. Her construction, participation in major naval actions, and service history exemplify her role as a key dreadnought of the Royal Navy during the early 20th century.
