HMS Caesar was a Majestic-class pre-dreadnought battleship built for the Royal Navy, featuring notable specifications and a distinguished service history. Constructed at Portsmouth Dockyard, her keel was laid in March 1895, and she was launched in September 1896, entering service in January 1898. She measured 421 feet (128 meters) in length overall, with a beam of 75 feet (23 meters) and a draft of 27 feet (8.2 meters). Displacing up to 16,060 long tons at full load, she was powered by two triple-expansion steam engines, initially coal-fired and later re-boilered with oil-fired boilers by 1907–1908, which enabled her to reach a top speed of 16 knots (30 km/h; 18 mph). Her crew comprised approximately 672 officers and ratings. Armament included a main battery of four 12-inch (305 mm) guns mounted in twin turrets on circular barbettes—rear and forward—unlike some of her sister ships which retained pear-shaped barbettes. Her secondary armament consisted of twelve 6-inch (152 mm) guns in casemates, supplemented by sixteen 12-pounder and twelve 2-pounder guns for defense against torpedo boats. She was also equipped with five 18-inch (457 mm) torpedo tubes—four submerged broadside tubes and one deck-mounted stern tube. The ship's armor featured a belt of Harvey steel 9 inches (229 mm) thick, providing substantial protection while maintaining a lighter, deeper belt due to the alloy's strength. The main gun barbettes were protected by 14 inches (356 mm) of armor, and the conning tower had similar thickness, with an armored deck ranging from 2.5 to 4.5 inches (64 to 114 mm). Caesar’s service included deployments across the Mediterranean, Channel, Atlantic, and later in various wartime roles during World War I. She participated in fleet reorganizations, served as flagship on multiple occasions, and was involved in notable incidents such as a collision in 1905 and being rammed by a barque in 1911. During WWI, she defended the English Channel, served as a guard and gunnery training ship at Gibraltar and Bermuda, and later as a depot ship supporting operations in the Aegean and Black Seas. Notably, she was the last British pre-dreadnought to serve outside the UK, concluding her active service in 1919 supporting operations against Bolsheviks in the Black Sea. Decommissioned in 1920, she was sold for scrap in 1921 and dismantled in Germany by 1922, marking the end of her maritime significance as a last operational example of her class.
