After Germany's defeat in the war and the signing of the Armistice in November 1918, the Royal Navy interned Kaiserin 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. Kaiserin was raised in May 1936 and subsequently broken up for scrap.
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 172.40m (565ft 7in) long overall and displaced a maximum of 27,000 metric tons (27,000 long tons) at full load. She had a beam of 29m (95ft 2in) and a draft of 9.10m (29ft 10in) forward and 8.80m (28ft 10in) aft. Kaiserin was powered by three sets of Parsons steam turbines, each of which drove a single screw propeller; they were supplied with steam by sixteen coal-fired water-tube boilers. The powerplant produced a top speed of 22.1 knots (40.9km/h; 25.4mph). She carried 3,600 metric tons (3,500 long tons; 4,000 short tons) of coal, which enabled a maximum range of 7,900 nautical miles (14,600km; 9,100mi) at a cruising speed of 12 knots (22km/h; 14mph).[2]
Kaiserin was armed with a main battery of ten 30.5 cm SK L/50 guns in five twin turrets.[2][lower-alpha 3] 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.[4][lower-alpha 4] 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 8.8cm (3.5in) SK L/45 guns in casemates. The ship was also armed with four 8.8cm L/45 anti-aircraft guns. The ship's armament was rounded out by five 50cm (19.7in)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 350mm (13.8in) thick in the central citadel, and was composed of Krupp cemented armor (KCA). Her main battery gun turrets were protected by 300mm (11.8in) of KCA on the sides and faces. Kaiserin's conning tower was heavily armored, with 400mm (15.7in) sides.[2]
Service history
Ordered under the contract name Ersatz Hagen as a replacement for the obsolete coastal defense shipHagen,[5][lower-alpha 5]Kaiserin was laid down at the Howaldtswerke dockyard in Kiel in November 1910.[6] She was launched on 11 November 1911, after which fitting-out work was completed.[7] At the launching ceremony, Admiral Hans von Koester gave a speech and Princess Victoria Louise christened the ship.[8] A dockyard crew delivered the ship to the Navy on 13 May 1913; she was commissioned into the fleet the following day. During trials the ship's turbine engines were damaged, and Kaiserin did not join the fleet until 13 December 1913.[7]
After joining III Battle Squadron in December 1913, Kaiserin 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.[7]Kaiserin 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.[9] Upon returning to Germany, Kaiserin steamed to Brunsbüttel on 24 July, where she was the first battleship to traverse the recently deepened Kaiser Wilhelm Canal. The voyage required lightening, and in just under twelve hours Kaiserin 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.[10] At midnight on 4 August, the United Kingdom, with its powerful Grand Fleet, declared war on Germany.[11]
Kaiserin 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.[10] This sortie was the initiation of a strategy adopted by Admiral Friedrich von Ingenohl, the commander of the High Seas Fleet. Admiral Ingenohl intended to use the battlecruisers of 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.[12] 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 Kaiserin and her four sisters—and eight pre-dreadnoughts came to within 10nmi (19km; 12mi) 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.[13]
Kaiserin 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.[10] The Kaiser removed Ingenohl from his post on 2 February, following the loss of SMSBlücher at the Battle of Dogger Bank the month before. Admiral Hugo von Pohl succeeded him as the commander of the fleet.[14] 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; Kaiserin 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.[10]
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 Vice Admiral Reinhard Scheer in January.[15] Scheer proposed a more aggressive policy designed to force a confrontation with the British Grand Fleet; he received approval from the Kaiser in February.[16] The first of Scheer's operations was conducted the following month, on 5 to 7 March, with an uneventful sweep of the Hoofden.[17]Kaiserin 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.[10]

Kaiserin was present during the fleet operation that resulted in the battle of Jutland which took place on 31 May and 1 June 1916; her commander at the time was Kapitän zur See (KzS) Karl Sievers.[18] 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, Kaiserin was the second ship in VI Division of III Squadron and the seventh ship in the line, directly astern of Kaiser and ahead of Prinzregent Luitpold. VI Division was behind only V Division, consisting of the four König-class battleships. The eight battleships of the Helgoland- and Nassau classes 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.[19][lower-alpha 6]
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 Indefatigable, shortly after 17:00,[20] and Queen Mary, less than half an hour later.[21] At 16:19, Kaiserin 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 Kaiserin came into action.[22] 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, König, spotted both IScouting 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.[23][lower-alpha 7]
At approximately 17:40, the British light cruiser Nottingham fired a single torpedo at Kaiserin at the extreme range of at least 16,500yd (15,100m), which failed to find its target.[24] After Scheer ordered the fleet to open fire, Kaiserin briefly engaged the battlecruiser New Zealand; Kaiserin 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.[25] The British destroyers Nestor and Nomad, which had been disabled earlier in the engagement, lay directly in the path of the advancing High Seas Fleet.[26]Kaiserin and her three sisters fired on Nomad with their secondary guns while the I Squadron battleships dispatched Nestor.[27] At around 19:00, the German battle line came into contact with the 2nd Light Cruiser Squadron; Kaiserin fired three salvos from her main battery at an unidentified four-funneled cruiser but made no hits.[28]
Shortly after 19:00, a shell from the British battlecruiser Invincible disabled the German cruiser Wiesbaden; Rear Admiral Behncke in König attempted to maneuver III Squadron to cover the stricken cruiser.[29] Simultaneously, the British 3rd and 4th Light Cruiser Squadrons began a torpedo attack on the German line; while advancing to torpedo range, they smothered Wiesbaden with fire from their main guns. The eight III Squadron battleships fired on the British cruisers, but even sustained fire from the battleships' main guns failed to drive off the British cruisers.[30] The armored cruisers Defence, Warrior, and Black Prince joined in the attack on the crippled Wiesbaden.[31] Between 19:14 and 19:17, several German battleships and battlecruisers opened fire on Defence and Warrior.[32]Kaiserin initially engaged one of the battleships in the British 5th Battle Squadron and scored a hit; according to Kaiserin's logs, the ship in question was Malaya.[33] After three minutes firing at Malaya, Kaiserin shifted fire to Defence.[32] In short succession, the German dreadnoughts hit Defence with several heavy caliber shells. One salvo penetrated the ship's ammunition magazines and, in a tremendous explosion, destroyed the cruiser.[34] After Defence exploded, Kaiserin shifted her fire to a target believed to be the battlecruiser Tiger. Heavy haze forced Kaiserin to check fire after two salvos.[35]
By 20:00, Scheer ordered the German line to complete a 180-degree turn eastward to disengage from the British fleet.[36] The maneuver, conducted under heavy fire, caused disorganization in the German fleet. Kaiserin had come too close to Prinzregent Luitpold and was forced to haul out of line to starboard to avoid a collision. The latter vessel came up alongside Kaiserin at high speed. As a result, Kaiserin had to remain out of line and could not return to her assigned position.[37] The turn reversed the order of the German line; Kaiserin was now the seventh ship from the rear of the German line.[38] At around 23:30, the German fleet reorganized into the night cruising formation. Kaiserin was the eleventh ship, in the center of the 24-ship line.[39]
After a series of night engagements between the leading battleships and British destroyers, the High Seas Fleet punched through the British light forces and reached Horns Reef by 04:00 on 1June.[40] The German fleet reached Wilhelmshaven a few hours later; the I Squadron battleships took up defensive positions in the outer roadstead and Kaiserin, Kaiser, Prinzregent Luitpold, and Kronprinz stood ready just outside the entrance to Wilhelmshaven.[41] The remainder of the battleships and battlecruisers entered Wilhelmshaven, where those that were still in fighting condition replenished their stocks of coal and ammunition.[42] In the course of the battle, Kaiserin fired one-hundred and sixty 30.5cm shells and one-hundred and thirty-five 15cm rounds.[43] She emerged from the battle completely unscathed.[10]
Subsequent operations
In early August, Kaiserin and the rest of the operational III Squadron units conducted divisional training in the Baltic.[10] On 18 August, Scheer attempted a repeat of the 31 May operation; the two serviceable German battlecruisers—Moltke and Von der Tann—supported by three dreadnoughts, were to bombard the coastal town of Sunderland in an attempt to draw out and destroy Beatty's battlecruisers. The rest of the fleet, including Kaiserin, would trail behind and provide cover.[44] On the approach to the English coast during the action of 19 August 1916, Scheer turned north after receiving a false report from a zeppelin about a British unit in the area.[45] As a result, the bombardment was not carried out, and by 14:35, Scheer had been warned of the Grand Fleet's approach and so turned his forces around and retreated to German ports.[46]
Another fleet advance followed on 18 to 20 October, though it ended without encountering any British units. Two weeks later, on 4 November, Kaiserin took part in an expedition to the western coast of Denmark to assist two U-boats, U-20 and U-30, that had become stranded there. The fleet was reorganized on 1 December;[10] the four König-class battleships remained in III Squadron, along with the newly commissioned Bayern, while the five Kaiser-class ships, including Kaiserin, were transferred to IV Squadron.[47] While transiting the Kaiser Wilhelm Canal on 14 March 1917, Kaiserin became grounded. One of her bilge keels was damaged and some 280t (280 long tons; 310 short tons) of water entered the ship. Repairs were conducted at the Imperial Dockyard in Kiel from 15 to 18 March. Kaiserin returned to the North Sea on 30 March and remained there on guard duty until 8 June. On 9 June, she went to the Baltic for a month-long series of exercises, which were completed on 2 July. She resumed guard duties in the German Bight on 3 July and continued in this role until 11 September, when Kaiserin was detached to join the special unit assigned to Operation Albion.[10]
In early September 1917, following the German conquest of the Russian port of Riga, the German navy decided to eliminate the Russian naval forces that still held the Gulf of Riga. The Admiralstab (the Navy High Command) planned an operation to seize the Baltic island of Ösel, and specifically the Russian gun batteries on the Sworbe Peninsula.[48] On 18 September, the order was issued for a joint operation with the army to capture Ösel and Moon Islands; the primary naval component was to comprise the flagship, Moltke, along with III and IVBattle Squadrons of the High Seas Fleet. Along with nine light cruisers, three torpedo boat flotillas, and dozens of mine warfare ships, the entire force numbered some 300 ships, supported by over 100 aircraft and six zeppelins. The invasion force amounted to approximately 24,600 officers and enlisted men.[49] By this time, IV Battle Squadron had come under the command of Vice Admiral Wilhelm Souchon.[50] Opposing the Germans were the old Russian pre-dreadnoughts Slava and Tsesarevich, the armored cruisersBayan, Admiral Makarov, and Diana, 26 destroyers, and several torpedo boats and gunboats. The garrison on Ösel numbered some 14,000 men.[51]
The operation began on the morning of 12 October, when Moltke and the III Squadron ships engaged Russian positions in Tagga Bay while Kaiserin and the rest of IV Squadron shelled Russian gun batteries on the Sworbe Peninsula on Ösel.[51]Kaiserin, along with Kaiser and Prinzregent Luitpold, were tasked with silencing the Russian guns at Hundsort on Ösel, which had taken Moltke under fire. The ships opened fire at 05:44, and by 07:45, Russian firing had ceased and German troops were moving ashore.[52] Two days later, Souchon left Tagga Bay with Kaiserin, Friedrich der Grosse, and Prinzregent Luitpold to support German ground forces advancing on the Sworbe Peninsula.[53]Kaiserin was assigned to suppress a Russian battery at Zerel, though heavy fog delayed her from engaging her target. The Russians opened fire first, which was quickly returned by Kaiserin and König Albert. Friedrich der Grosse came to the two ships' assistance; the three battleships fired a total of 120 large-caliber shells over the span of an hour. The fourth Russian salvo straddledKaiserin, which began to steer erratically to avoid the Russian gunfire. The heavy firing prompted most of the Russian gun crews to flee their posts.[54]
On the night of 15 October, Kaiserin and König Albert were sent to replenish their coal stocks in Putzig.[55] On the 19th, they were briefly joined in Putzig by Friedrich der Grosse, which continued on to Arensburg with Moltke.[56] The next morning, Vice Admiral Ehrhard Schmidt ordered the special naval unit to be dissolved and returned to the North Sea. In a communique to the naval headquarters, Schmidt noted that "Kaiserin and König Albert can immediately be detached from Putzig to the North Sea."[57] The two ships then proceeded to Kiel via Danzig; after reaching Kiel, they transited the Kaiser Wilhelm Canal back to the North Sea.[58]
Final operations
On 17 November 1917, Kaiserin and Kaiser were assigned to provide cover for II Scouting Group while it conducted a minesweeping operation in the North Sea. Significant British forces, including five battlecruisers and several light cruisers, attacked II Scouting Group; the two battleships immediately steamed to their assistance. In the ensuing Second Battle of Heligoland Bight, Kaiserin scored a hit on the light cruiser Caledon.[58] The battlecruiser Repulse briefly engaged the German dreadnoughts, but both forces withdrew.[59] After the action, Rear Admiral Ludwig von Reuter criticized Kaiserin's commander, KzSKurt Graßhoff, for lagging too far behind the minesweepers to provide adequate protection. He was subsequently relieved of command of the ship.[60]Kaiserin went into drydock for maintenance on 22 December, and work lasted until 5 February 1918. The ship participated in the fruitless advance to Norway on 23–25 April 1918, which had been intended to intercept a heavily defended convoy between Britain and Norway; faulty German intelligence prevented the Germans from catching the convoy.[61] After returning to port, she resumed guard duties in the German Bight. IV Squadron undertook another training exercise in the Baltic from 18 June to 13 August. A final round of drills took place on 22–28 October.[58]

Kaiserin and her four sisters were to have taken part in a final fleet action at the end of October 1918, days before the Armistice was to take effect. The bulk of the High Seas Fleet was to have sortied from its base in Wilhelmshaven to engage the British Grand Fleet; Scheer—by now the Grand Admiral (Großadmiral) of the fleet—intended to inflict as much damage as possible on the British navy. The goal was to improve Germany's bargaining position in the imminent peace negotiations, despite the expected casualties. But many of the war-weary sailors felt that the operation would disrupt the peace process and prolong the war.[62] On the morning of 29 October 1918, the order was given to sail from Wilhelmshaven the following day. Starting on the night of 29 October, sailors on Thüringen and then on several other battleships mutinied.[63] The unrest ultimately forced Hipper and Scheer to cancel the operation.[64] Informed of the situation, the Kaiser stated, "I no longer have a navy."[65]
Following the capitulation of Germany in November 1918, the Allies interned most of the High Seas Fleet, under the command of Rear Admiral Ludwig von Reuter, in the British naval base in Scapa Flow.[64] Prior to the departure of the German fleet, Admiral Adolf von Trotha made clear to Reuter that he could not allow the Allies to seize the ships, under any circumstances.[66] The fleet rendezvoused with the British light cruiserCardiff, which led the ships to the Allied fleet that was to escort the Germans to Scapa Flow. The massive fleet consisted of some 370 British, American, and French warships.[67] Once the ships were interned, their guns were disabled through the removal of their breech blocks, and their crews were reduced to 200 officers and enlisted men.[68]
The fleet remained in captivity during the negotiations that ultimately produced the Treaty of Versailles. Reuter believed that the British intended to seize the German ships on 21 June 1919, which was the deadline for Germany to have signed the peace treaty. Unaware that the deadline had been extended to the 23rd, Reuter ordered the ships to be sunk at the next opportunity. On the morning of 21 June, the British fleet left Scapa Flow to conduct training maneuvers, and at 11:20 Reuter transmitted the order to his ships.[66]Kaiserin sank at 14:00; she was subsequently raised on 14 May 1936 and broken up later that year in Rosyth.[2]

Carl Friedrich Heinrich Reinhard Scheer was an Admiral in the Imperial German Navy. Scheer joined the navy in 1879 as an officer cadet and progressed through the ranks, commanding cruisers and battleships, as well as senior staff positions on land. At the outbreak of World War I, Scheer was the commander of the II Battle Squadron of the High Seas Fleet. He then took command of the III Battle Squadron, which consisted of the newest and most powerful battleships in the navy. In January 1916, he was promoted to Admiral and given control of the High Seas Fleet. Scheer led the German fleet at the Battle of Jutland on 31 May – 1 June 1916, one of the largest naval battles in history.
SMS Kaiser 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. Kaiser was assigned to III Battle Squadron of the High Seas Fleet for the majority of World War I.
SMS König was the first of four König-class dreadnought battleships of the Imperial German Navy during World War I. König was named in honor of King William II of Württemberg. The battleship was armed with ten 30.5-centimeter (12 in) guns in five twin turrets and could steam at a top speed of 21 knots. Laid down in October 1911, the ship was launched on 1 March 1913. The construction of König was completed shortly after the outbreak of World War I; she was commissioned into the High Seas Fleet on 9 August 1914.
SMS Nassau was the first dreadnought battleship built for the Imperial German Navy, a response to the launching of the British battleship HMS Dreadnought. Nassau was laid down on 22 July 1907 at the Kaiserliche Werft in Wilhelmshaven, and launched less than a year later on 7 March 1908, approximately 25 months after Dreadnought. She was the lead ship of her class of four battleships, which included Posen, Rheinland, and Westfalen.
SMS Kronprinz was the last dreadnought battleship of the four-ship König class of the German Imperial Navy. The battleship was laid down in November 1911 and launched on 21 February 1914. She was formally commissioned into the Imperial Navy on 8 November 1914, just over 3 months after the start of World War I. The name Kronprinz refers to Crown Prince Wilhelm, and in June 1918, the ship was renamed Kronprinz Wilhelm in his honor. The battleship was armed with ten 30.5-centimeter (12 in) guns in five twin turrets and could steam at a top speed of 21 knots.
The König class was a group of four dreadnought battleships built for the German Kaiserliche Marine in the early 1910s. The class comprised König, the lead ship, Grosser Kurfürst, Markgraf, and Kronprinz. The design for the ships was derived from the preceding Kaiser class, using the same basic hull but with a rearranged main battery of ten 30.5 cm (12 in) guns in five twin-gun turrets to improve the guns' firing arcs. Instead of the staggered wing turrets used in the Kaisers, the Königs placed their main guns all on the centerline using superfiring pairs fore and aft. Budgetary constraints and the need to begin construction quickly to compete with Britain in the Anglo-German naval arms race prevented any more radical changes. Diesel engines were planned for the ships, but they could not be readied in time, so all four vessels reverted to steam turbines for their propulsion system.
The Kaiser class was a class of five dreadnought battleships that were built in Germany prior to World War I and served in the Kaiserliche Marine during the war. They were the third class of German dreadnoughts, and the first to feature turbine engines and superfiring turrets. The five ships were Kaiser, Friedrich der Grosse, Kaiserin, Prinzregent Luitpold, and König Albert. As was usual for German battleships of the period, the Kaiser class mounted main guns that were smaller than those of their British rivals: 30.5 cm (12 in), compared to the 34.3 cm (13.5 in) guns of the British Orion class.
SMS Westfalen was one of the Nassau-class battleships, the first four dreadnoughts built for the German Imperial Navy. Westfalen was laid down at AG Weser in Bremen on 12 August 1907, launched nearly a year later on 1 July 1908, and commissioned into the High Seas Fleet on 16 November 1909. The ship was equipped with a main battery of twelve 28 cm (11 in) guns in six twin turrets in an unusual hexagonal arrangement.
The Nassau class was a group of four dreadnought battleships built for the German Kaiserliche Marine in the early 1900s. The class comprised Nassau, the lead ship, Rheinland, Posen, and Westfalen. All four ships were laid down in mid-1907, and completed by late 1910. Though commonly perceived as having been built in response to the British Dreadnought, their design traces its origin to 1903; they were in fact a response to Dreadnought's predecessors of the Lord Nelson class. The Nassaus adopted a main battery of twelve 28 cm (11 in) guns in six twin-gun turrets in an unusual hexagonal arrangement. Unlike many other dreadnoughts, the Nassau-class ships retained triple-expansion steam engines instead of more powerful steam turbines.
SMS Hannover was the second of five Deutschland-class pre-dreadnought battleships of the German Imperial Navy. Hannover and the three subsequently constructed ships differed slightly from the lead ship Deutschland in their propulsion systems and slightly thicker armor. Hannover was laid down in November 1904, launched in May 1905, and commissioned into the High Seas Fleet in October 1907. The ship was armed with a battery of four 28 cm (11 in) guns and had a top speed of 18 knots. The ships of her class were already outdated by the time they entered service, being inferior in size, armor, firepower, and speed to the revolutionary new British battleship HMS Dreadnought.
SMS Deutschland was the first of five Deutschland-class pre-dreadnought battleships built for the German Kaiserliche Marine. The ship was armed with a main battery of four 28 cm (11 in) guns in two twin turrets. She was built at the Germaniawerft shipyard in Kiel, where she was laid down in June 1903 and launched in November 1904. She was commissioned on 3 August 1906, a few months ahead of HMS Dreadnought. The latter, armed with ten large-caliber guns, was the first of a revolutionary new standard of "all-big-gun" battleships that rendered Deutschland and the rest of her class obsolete.
SMS Markgraf was the third dreadnought battleship of the four-ship König class. She served in the Imperial German Navy during World War I. The battleship was laid down in November 1911 and launched on 4 June 1913. She was formally commissioned into the Imperial Navy on 1 October 1914, just over two months after the outbreak of war in Europe. Markgraf was armed with ten 30.5-centimeter (12 in) guns in five twin turrets and could steam at a top speed of 21 knots. Markgraf was named in honor of the royal family of Baden. The name Markgraf is a rank of German nobility and is equivalent to the English Margrave, or Marquess.
SMS Grosser Kurfürst was the second dreadnought battleship of the four-ship König class. Grosser Kurfürst served in the Imperial German Navy during World War I. The battleship was laid down in October 1911 and launched on 5 May 1913. She was formally commissioned into the Imperial Navy on 30 July 1914, days before the outbreak of war between Germany and the United Kingdom. Her name means Great Elector, and refers to Frederick William I, the Prince-elector of Brandenburg. Grosser Kurfürst was armed with ten 30.5-centimeter (12 in) guns in five twin turrets and could steam at a top speed of 21 knots.
SMS Friedrich der Grosse was the second vessel of the Kaiser class of dreadnought battleships of the German Imperial Navy. Friedrich der Grosse's keel was laid on 26 January 1910 at the AG Vulcan dockyard in Hamburg, her hull was launched on 10 June 1911, and she was commissioned into the fleet on 15 October 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. Friedrich der Grosse was assigned to III Battle Squadron of the High Seas Fleet for the majority of World War I, and served as fleet flagship from her commissioning until 1917.
SMS Prinzregent Luitpold was the fifth and final vessel of the Kaiser class of dreadnought battleships of the Imperial German Navy.

The High Seas Fleet was the battle fleet of the German Imperial Navy and saw action during the First World War. The formation was created in February 1907, when the Home Fleet was renamed as the High Seas Fleet. Admiral Alfred von Tirpitz was the architect of the fleet; he envisioned a force powerful enough to challenge the Royal Navy's predominance. Kaiser Wilhelm II, the German Emperor, championed the fleet as the instrument by which he would seize overseas possessions and make Germany a global power. By concentrating a powerful battle fleet in the North Sea while the Royal Navy was required to disperse its forces around the British Empire, Tirpitz believed Germany could achieve a balance of force that could seriously damage British naval hegemony. This was the heart of Tirpitz's "Risk Theory", which held that Britain would not challenge Germany if the latter's fleet posed such a significant threat to its own.
