HMS Bellerophon was a central battery ironclad built for the Royal Navy in the mid-1860s, designed by Sir Edward Reed. She measured 280 feet (85.3 meters) between perpendiculars, with a beam of 56 feet 1 inch (17.1 meters) and a maximum draught of 26 feet 7 inches (8.1 meters). Her hull featured a distinctive U-shaped profile at the bow and stern, enhancing buoyancy, while a double bottom allowed for a higher placement of her engine, contributing to her stability as a gun platform. The ship was equipped with a single 2-cylinder trunk steam engine made by John Penn and Sons, driving a 23-foot-6-inch (7.2 meters) propeller, with eight rectangular boilers generating a working pressure of 27 psi. During sea trials in August 1864, she produced 6,521 indicated horsepower, reaching a maximum speed of 14.17 knots, and carried 640 long tons of coal for a range of approximately 1,500 nautical miles at 8 knots. Her armament initially comprised ten 9-inch rifled muzzle-loading guns mounted on the main deck, complemented by five 7-inch guns outside the main battery, and four breech-loading 12-pounder Armstrong guns. Notably, Bellerophon was the first British ironclad to carry the 9-inch rifled muzzle-loader. The ship's armor included a 6-inch wrought iron waterline belt amidships, tapering to 5 inches at the bow and stern, with a 6-foot high armored section protecting the central battery. The armor was backed by 8–10 inches of teak, providing substantial protection against contemporary weaponry. The vessel's construction featured a shift from longitudinal girders to a "bracket frame" system devised by Nathaniel Barnaby, which allowed for a double bottom and reduced weight. Laid down in December 1863, launched in April 1865, and commissioned in March 1866, Bellerophon served initially with the Channel Fleet, later with the Mediterranean Fleet, and then as flagship on the North America and West Indies Station. An extensive refit in the 1880s modernized her armament to breech-loaders and included new boilers. She remained in service until 1903, after which she became a port guardship and later a stokers' training ship, renamed HMS Indus III. Ultimately sold for scrap in 1922, HMS Bellerophon exemplified the evolution of naval armor and firepower during a transformative period in maritime warfare.
