HMS Valiant was a Hector-class armored frigate built for the Royal Navy, launched in 1863 after a prolonged construction period caused by her builders' bankruptcy and supply delays. She measured 280 feet 2 inches (85.4 meters) between perpendiculars, with a beam of 56 feet 4 inches (17.2 meters) and a draft of 26 feet 2 inches (8 meters). Displacing approximately 7,000 long tons (7,100 tonnes), the vessel featured a hull subdivided by 92 watertight compartments and a double bottom beneath the engine and boiler rooms, emphasizing her robust construction and compartmentalization for seaworthiness. Her low center of gravity, with a metacentric height of 4 feet 6 inches (1.4 meters), contributed to her maneuverability but also resulted in notable rolling. Propelled by a single 2-cylinder horizontal-return connecting-rod steam engine built by Maudslay Sons & Field, Valiant's engine generated 3,560 indicated horsepower, reaching a maximum speed of 12.65 knots during sea trials in 1865. She was rigged as a barque, with a sail area of 24,500 square feet (2,276 m²), and was equipped with a semi-retractable funnel to reduce wind resistance under sail. Her coal capacity of 450 long tons allowed an operational range of approximately 800 nautical miles at full speed. Initially armed with a combination of rifled 110-pounder breech-loading guns and 68-pounder muzzle-loaders, her armament was ultimately limited to sixteen 7-inch and two 8-inch rifled muzzle-loading guns due to delays in adopting newer weaponry. Her armor consisted of a wrought-iron waterline belt 4.5 inches thick, covering 216 feet amidships, and backed by 18 inches of teak, with additional armored protection on the main deck. Notably, the stern lacked armor, leaving the steering gear vulnerable. Throughout her service, Valiant served primarily as the First Reserve guard ship in Southern Ireland from 1868 to 1885, with a brief stint with the Particular Service Squadron during the Russo-Turkish War. She was involved in a collision with HMS Defence in 1884, which caused hull damage. Decommissioned in 1885, she was later repurposed as a training hulk, storeship, kite balloon depot, and finally as a floating oil tank before being sold for scrap in 1956. Her varied career reflects the transitional period of naval technology from ironclads to more modern vessels.
