SMS was the third vessel of the of dreadnought battleships of the Imperial German Navy. s keel was laid in November 1910 at the Howaldtswerke dockyard in Kiel. She was launched on 11 November 1911 and was commissioned into the fleet on 14 May 1913. The ship was equipped with ten guns in five twin turrets, and had a top speed of . was assigned to III Battle Squadron and later IV Battle Squadron of the High Seas Fleet for the majority of her career, including World War I.

Along with her four sister ships, , , , and , participated in all of the major fleet operations of World War I, including the Battle of Jutland on 31 May and 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 October 1917. She later saw action during the Second Battle of Heligoland Bight in November 1917.

After Germany's defeat in the war and the signing of the Armistice in November 1918, the Royal Navy interned and most of the capital ships of the High Seas Fleet 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, 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. was raised in May 1936 and subsequently broken up for scrap.

Design

The German 1909 construction program included the last two members of the s, 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 s. 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 and es, even if markedly inferior in terms of firepower.

Characteristics

The ship was long overall and displaced a maximum of at full load. She had a beam of and a draft of forward and 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. 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.

was powered by three sets of Parsons steam 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 . She carried of coal, which enabled a maximum range of at a cruising speed of .

was armed with a main battery of ten 30.5 cm SK L/50 guns in five twin turrets. The ship dispensed with the inefficient hexagonal turret 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, such that both could fire on the broadside. The ship was also armed with a secondary battery of fourteen 15 cm SK L/45 guns in casemates amidships. For close-range defense against torpedo boats, she carried eight 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 torpedo tubes, all mounted in the hull; one was in the bow, and the other four were on the broadside.

Her main armored belt was thick in the central citadel, and was composed of Krupp cemented armor (KCA). Her main battery gun turrets were protected by of KCA on the sides and faces. s conning tower was heavily armored, with sides.

Service history Ordered under the contract name as a replacement for the obsolete coastal defense ship , was laid down at the Howaldtswerke dockyard in Kiel in November 1910. She was launched on 11 November 1911, after which fitting-out work was completed. At the launching ceremony, Admiral Hans von Koester gave a speech and Princess Victoria Louise christened the ship. A dockyard crew delivered the ship to the Navy on 13 May 1913; she was commissioned into the fleet the following day, and she was assigned to V Division, III Battle Squadron, to replace the old battleship . During trials the ship's turbine engines were damaged, and did not join the fleet until 13 December due to the necessary repairs. (KzS—Captain at Sea) Her first commander was Karl Sievers.

After joining III Squadron, participated in the routine fleet training exercises. Squadron exercises were conducted in February, followed by fleet maneuvers, both in the North Sea. The fleet trained again in May, in both the North and Baltic Seas. left Germany on 7 July for the annual summer cruise to Norway, but was recalled prematurely on 22 July because of rising international tensions following the assassination of Archduke Franz Ferdinand. Upon returning to Germany, steamed to Brunsbüttel on 24 July, where she was the first battleship to traverse the recently deepened Kaiser Wilhelm Canal. The test was carried out to determine if the new depth was sufficient for the largest battleships, which had particular importance given the rapidly increasing tensions in Europe. The voyage required lightening, and in just under twelve hours exited the locks at Holtenau in Kiel where she met the rest of her squadron. On 31 July, the entire squadron returned to the North Sea via the Canal. Following the outbreak of war on 28 July and the subsequent German invasion of Belgium and France, the United Kingdom declared war on Germany at midnight on 4 August.

World War I was present during the first sortie by the German fleet into the North Sea, which took place on 2–3 November 1914. No British forces were encountered during the operation. A second operation followed on 15–16 December. This sortie was the initiation of a strategy adopted by Admiral Friedrich von Ingenohl, the commander of the High Seas Fleet. Ingenohl intended to use the battlecruisers of (KAdm—Rear Admiral) Franz von Hipper's I Scouting Group to raid British coastal towns to lure out portions of the Grand Fleet where they could be destroyed by the High Seas Fleet. Early on 15 December the fleet left port to raid the towns of Scarborough, Hartlepool, and Whitby. That evening, the German battle fleet of some twelve dreadnoughts—including and her four sisters—and eight pre-dreadnoughts came to within of an isolated squadron of six British battleships. However, skirmishes between the rival destroyer screens in the darkness convinced Ingenohl that he was faced with the entire Grand Fleet. Under orders from Kaiser Wilhelm II to avoid risking the fleet unnecessarily, Ingenohl broke off the engagement and turned the battle fleet back toward Germany.

went into the Baltic for squadron training from 23 to 29 January 1915. Upon returning to the North Sea, the ship went into drydock in Wilhelmshaven for periodic maintenance, which lasted from 31 January to 20 February. The Kaiser removed Ingenohl from his post on 2 February, following the loss of at the Battle of Dogger Bank the month before. Admiral Hugo von Pohl succeeded him as the commander of the fleet. Pohl continued the policy of sweeps into the North Sea to destroy isolated British formations. The fleet conducted a series of advances into the North Sea throughout 1915; was present for the sweeps on 17 to 18 May, 29 to 30 May, 10 August, 11 to 12 September, and 23 to 24 October. III Squadron completed the year with another round of unit training in the Baltic from 5 to 20 December.

Pohl's tenure as fleet commander was brief; by January 1916 hepatic cancer had weakened him to the point where he was no longer able to carry out his duties. He was replaced by (VAdm—Vice Admiral) Reinhard Scheer in January. Scheer proposed a more aggressive policy designed to force a confrontation with the British Grand Fleet; he received approval from the Kaiser in February. The first of Scheer's operations was conducted the following month, on 5 to 7 March, with an uneventful sweep of the Hoofden. was also present during an advance to the Amrun Bank on 2 to 3 April. The fleet conducted another sortie on 21 to 22 April.

Battle of Jutland

was present during the fleet operation that resulted in the battle of Jutland which took place on 31 May and 1 June 1916. The German fleet again sought to draw out and isolate a portion of the Grand Fleet and destroy it before the main British fleet could retaliate. During the operation, was the second ship in VI Division of III Squadron and the seventh ship in the line, directly astern of and ahead of . VI Division was behind only V Division, consisting of the four s. The eight battleships of the Helgoland- and es assigned to I and II Divisions in I Squadron followed VI Division. The six elderly pre-dreadnoughts of III and IV Divisions, II Battle Squadron, formed the rear of the formation.

Shortly before 16:00, the battlecruisers of I Scouting Group encountered the British 1st Battlecruiser Squadron under the command of Vice Admiral David Beatty. The opposing ships began an artillery duel that saw the destruction of , shortly after 17:00, and , less than half an hour later. At 16:19, was forced to temporarily stop the turbine on the center shaft, as the condenser had started leaking. The crew were able to restart the engine before came into action. By this time, the German battlecruisers were steaming south to draw the British ships toward the main body of the High Seas Fleet. At 17:30, the crew of the leading German battleship, , spotted both I Scouting Group and the 1st Battlecruiser Squadron approaching. The German battlecruisers were steaming to starboard, while the British ships steamed to port. At 17:45, Scheer ordered a two-point turn to port to bring his ships closer to the British battlecruisers, and a minute later, the order to open fire was given.

At approximately 17:40, the British light cruiser fired a single torpedo at at the extreme range of at least , which failed to find its target. After Scheer ordered the fleet to open fire, briefly engaged the battlecruiser ; failed to score a hit and by 17:54 New Zealand and the rest of the British battlecruisers had increased speed and moved out of range. The British destroyers and , which had been disabled earlier in the engagement, lay directly in the path of the advancing High Seas Fleet. and her three sisters fired on Nomad with their secondary guns while the I Squadron battleships dispatched Nestor. At around 19:00, the German battle line came into contact with the 2nd Light Cruiser Squadron; fired three salvos from her main battery at an unidentified four-funneled cruiser but made no hits.
