SMS Prinzregent Luitpold[a] was the fifth and final vessel of the Kaiser class of dreadnought battleships of the Imperial German Navy. Prinzregent Luitpold's keel was laid in October 1910 at the Germaniawerft dockyard in Kiel. She was launched on 17 February 1912 and was commissioned into the navy on 19 August 1913. The ship was equipped with ten 30.5-centimeter (12 in) guns in five twin turrets, and had a top speed of 21.7 knots (40.2 km/h; 25.0 mph).

Prinzregent Luitpold was assigned to III Battle Squadron of the High Seas Fleet for the majority of her career; in December 1916, she was transferred to IV Battle Squadron. Along with her four sister ships, Kaiser, Friedrich der Grosse, Kaiserin, and König Albert, Prinzregent Luitpold participated in all of the major fleet operations of World War I, including the Battle of Jutland on 31 May – 1 June 1916. The ship was also involved in Operation Albion, an amphibious assault on the Russian-held islands in the Gulf of Riga, in late 1917.

After Germany's defeat in the war and the signing of the Armistice in November 1918, Prinzregent Luitpold and most of the capital ships of the High Seas Fleet were interned by the Royal Navy in Scapa Flow. The ships were disarmed and reduced to skeleton crews while the Allied powers negotiated the final version of the Treaty of Versailles. On 21 June 1919, days before the treaty was signed, the commander of the interned fleet, Rear Admiral Ludwig von Reuter, ordered the fleet to be scuttled to ensure that the British would not be able to seize the ships. Prinzregent Luitpold was raised in July 1931 and subsequently broken up for scrap in 1933.

Characteristics

The German 1909 construction program included the last two members of the Helgoland-class battleships, along with two additional dreadnoughts to be built to a new design. The primary change was intended to be the adoption of steam turbines in favor of triple-expansion steam engines used in the earlier vessels. The space savings of turbines permitted a more efficient superfiring arrangement of the main battery, along the same model as the Moltke-class battlecruisers. The new ships' armor layout was significant improved over earlier designs; the Kaiser class was also far superior in defensive characteristics to their British counterparts of the King George V and Iron Duke classes, even if markedly inferior in terms of firepower.[1]

Prinzregent Luitpold was 172.4 m (565 ft 7 in) long overall and displaced a maximum of 27,000 metric tons (26,570 long tons) at full load. She had a beam of 29 m (95 ft 2 in) and a draft of 9.1 m (29 ft 10 in) forward and 8.8 m (28 ft 10 in) aft. The ship had an inverted bow and a long forecastle deck that extended for two-thirds the length of the hull. Her superstructure was fairly minimal, consisting primarily of a short, armored conning tower forward and a smaller, secondary conning tower aft. Prinzregent Luitpold was fitted with a pair of pole masts for observation and signaling purposes. She had a crew of 41 officers and 1,043 enlisted men.[2]

Prinzregent Luitpold was powered by two sets of Parsons steam turbines, which drove two screw propellers. The turbines were supplied with steam by fourteen coal-fired water-tube boilers that were vented through a pair of widely spaced funnels. Unlike her four sisters, the ship was intended to use a diesel engine on the center shaft, but this was not ready by the time work on the ship was completed. The engine was never installed, and so Prinzregent Luitpold was slightly slower than her sisters, which were equipped with a third turbine on the center shaft. The powerplant produced a top speed of 21.7 knots (40.2 km/h; 25.0 mph). She carried 3,600 metric tons (3,540 long tons) of coal, which enabled a maximum range of 7,900 nautical miles (14,630 km; 9,090 mi) at a cruising speed of 12 knots (22 km/h; 14 mph).[2]

Prinzregent Luitpold was armed with a main battery of ten 30.5 cm SK L/50 guns in five twin turrets.[2][b] The ship dispensed with the inefficient hexagonal turret arrangement of previous German battleships; instead, three of the five turrets were mounted on the centerline, one forward and two of them arranged in a superfiring pair aft. The other two turrets were placed en echelon amidships, such that both could fire on the broadside.[4] The ship was also armed with a secondary battery of fourteen 15 cm (5.9 in) SK L/45 guns in casemates amidships. For close-range defense against torpedo boats, she carried eight 8.8 cm (3.5 in) SK L/45 guns in casemates. The ship was also armed with four 8.8 cm L/45 anti-aircraft guns. The ship's armament was rounded out by five 50 cm (19.7 in) torpedo tubes, all mounted in the hull; one was in the bow, and the other four were on the broadside.[2]

Her main armored belt was 350 mm (13.8 in) thick in the central citadel, and was composed of Krupp cemented armor (KCA). Her main battery gun turrets were protected by 300 mm (11.8 in) of KCA on the sides and faces. Prinzregent Luitpold's conning tower was heavily armored, with 400 mm (15.7 in) sides.[2]
