HMS Immortalité was one of seven Orlando-class armoured cruisers built for the Royal Navy in the mid-1880s. She was sold for scrap on 11 January 1907.
Design and description
Immortalité had a length between perpendiculars of 300 feet (91.4 m), a beam of 56 feet (17.1 m) and a draught of 24 feet (7.3 m). Designed to displace 5,040 long tons (5,120 t), all of the Orlando-class ships proved to be overweight and displaced approximately 5,535 long tons (5,624 t). The ship was powered by a pair of three-cylinder triple-expansion steam engines, each driving one shaft, which were designed to produce a total of 8,500 indicated horsepower (6,300 kW) and a maximum speed of 18 knots (33 km/h; 21 mph) using steam provided by four boilers with forced draught. The ship carried a maximum of 900 long tons (910 t) of coal which was designed to give her a range of 8,000 nautical miles (15,000 km; 9,200 mi) at a speed of 10 knots (19 km/h; 12 mph). The ship's complement was 484 officers and enlisted men.[1]
Immortalité's main armament consisted of two breech-loading (BL) 9.2-inch (234 mm) Mk V guns, one gun fore and aft of the superstructure on pivot mounts. Her secondary armament was ten BL 6-inch (152 mm) guns, five on each broadside. Protection against torpedo boats was provided by six quick-firing (QF) 6-pounder Hotchkiss guns and ten QF 3-pounder Hotchkiss guns, most of which were mounted on the main deck in broadside positions. The ship was also armed with six 18-inch (457 mm) torpedo tubes: four on the broadside above water and one each in the bow and stern below water.[1]
The ship was protected by a waterline compound armour belt 10 inches (254 mm) thick. It covered the middle 200 feet (61.0 m) of the ship and was 5 feet 6 inches (1.7 m) high.[1] Because the ship was overweight, the top of the armour belt was 2 feet (0.61 m) below the waterline when she was fully loaded.[2] The ends of the armour belt were closed off by transverse bulkheads 16 inches (406 mm). The lower deck was 2–3 inches (51–76 mm) thick over the full length of the hull. The conning tower was protected by 12 inches (305 mm) of armour.[1]

Immortalité, named for the French frigate Immortalité captured in 1798,[3] was laid down on 18 January 1886 by Chatham Royal Dockyard. The ship was launched on 7 June 1887, and completed in July 1889.[4]
She was commissioned at Chatham 21 May 1901 by Captain Sackville H. Carden as seagoing tender to the Wildfire, flagship at Sheerness.[5]
