HMS Undaunted was an Orlando-class armoured cruiser constructed for the Royal Navy in the mid-1880s. She measured 300 feet (91.4 meters) between perpendiculars, with a beam of 56 feet (17.1 meters) and a draught of 24 feet (7.3 meters). Designed to displace 5,040 long tons (5,120 tonnes), she was overweight at approximately 5,535 long tons (5,624 tonnes). Powered by two triple-expansion steam engines producing a total of 8,500 indicated horsepower, Undaunted could reach speeds up to 19.4 knots during sea trials, surpassing her designed maximum of 18 knots. Her propulsion system was supplemented by four boilers with forced draught, and she carried a coal capacity of 900 long tons (910 tonnes), enabling an operational range of 8,000 nautical miles at 10 knots. Her armament was formidable for her class, featuring two breech-loading 9.2-inch (234 mm) Mk V guns—one fore and one aft—mounted on pivoting bases. She also carried ten 6-inch (152 mm) guns arranged five on each broadside, along with quick-firing Hotchkiss guns for defence against torpedo boats: six 6-pounder and ten 3-pounder guns. For offensive capabilities, Undaunted was equipped with six 18-inch (457 mm) torpedo tubes—four above water on the broadside and one below water at each end. Protection was provided by a 10-inch (254 mm) waterline compound armour belt covering the central 200 feet of the hull, although overweight conditions left the top of the belt 2 feet below the waterline when fully loaded. The armour extended to transverse bulkheads, and the conning tower was protected by 12 inches (305 mm) of armour. Laid down in April 1885 at Palmers' shipyard in Jarrow and launched in November 1886, Undaunted was completed in September 1890. Her service included deployment with the Mediterranean Fleet under Sir George Tryon, during which she experienced a minor collision in 1893 after striking rocks near Alexandria due to navigational error. She also served twice on the China Station before being placed in reserve in 1901. Subsequently, she served as a tender to HMS Cambridge before being sold for scrap in April 1907.
