SMS Kaiser[a] was the lead ship of the Kaiser class of dreadnought battleships of the Imperial German Navy. Kaiser was built by the Imperial Dockyard at Kiel, launched on 22 March 1911 and commissioned on 1 August 1912. The ship was equipped with ten 30.5-centimeter (12 in) guns in five twin turrets, and had a top speed of 23.4 knots (43.3 km/h; 26.9 mph). Kaiser was assigned to III Battle Squadron of the High Seas Fleet for the majority of World War I.

In 1913, Kaiser and her sister König Albert conducted a cruise to South America and South Africa. The ship participated in most of the major fleet operations during the war. She fought at the Battle of Jutland on 31 May – 1 June 1916, during which she was hit twice and suffered negligible damage. The ship was also present during Operation Albion in the Baltic Sea in September and October 1917, and at the Second Battle of Heligoland Bight in November 1917.

During peace negotiations after the end of the war in 1918, she was interned with other ships of the High Seas Fleet at Scapa Flow. On 21 June 1919 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. The wreck was raised in 1929 and broken up in Rosyth in 1930.

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]

The ship 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 8.80 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. Kaiser had additional facilities for an admiral's staff, as she was intended to serve as a divisional flagship. The ship 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][3]

Kaiser was powered by three sets of Parsons turbines, which drove three screw propellers. The turbines were supplied with steam by sixteen coal-fired water-tube boilers that were vented through a pair of widely spaced funnels. The powerplant produced a top speed of 23.4 knots (43.3 km/h; 26.9 mph). She carried 3,600 metric tons (3,500 long tons) of coal, which enabled a maximum range of 7,900 nautical miles (14,600 km; 9,100 mi) at a cruising speed of 12 knots (22 km/h; 14 mph).[2]

Kaiser 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 arrangement of previous German battleships; instead, three of the five turrets were mounted on the centerline, with two of them arranged in a superfiring pair aft. The other two turrets were placed en echelon amidships, so that both could fire on the broadside.[5] 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 ship's 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. Kaiser's conning tower was heavily armored, with 400 mm (15.7 in) sides.[2]
