The ship served with her sister ships for the majority of World War I, seeing extensive service in the North Sea, where she took part in several fleet sorties. These culminated in the Battle of Jutland on 31 May– 1 June 1916, where Westfalen was heavily engaged in night-fighting against British light forces. Westfalen led the German line for much of the evening and into the following day, until the fleet reached Wilhelmshaven. On another fleet advance in August 1916, the ship was damaged by a torpedo from a British submarine.
Westfalen also conducted several deployments to the Baltic Sea against the Russian Navy. The first of these was during the Battle of the Gulf of Riga, where Westfalen supported a German naval assault on the gulf. Westfalen was sent back to the Baltic in 1918 to support the White Finns in the Finnish Civil War. The ship remained in Germany while the majority of the fleet was interned in Scapa Flow after the end of the war. In 1919, following the scuttling of the German fleet in Scapa Flow, Westfalen was ceded to the Allies as a replacement for the ships that had been sunk. She was then sent to ship-breakers in England, who broke the ship up for scrap by 1924.
Design work on the Nassau class began in late 1903 in the context of the Anglo-German naval arms race; at the time, battleships of foreign navies had begun to carry increasingly heavy secondary batteries, including Italian and American ships with 20.3cm (8in) guns and British ships with 23.4cm (9.2in) guns, outclassing the previous German battleships of the Deutschland class with their 17cm (6.7in) secondaries. German designers initially considered ships equipped with 21cm (8.3in) secondary guns, but erroneous reports in early 1904 that the British Lord Nelson-class battleships would be equipped with a secondary battery of 25.4cm (10in) guns prompted them to consider an even more powerful ship armed with an all-big-gun armament consisting of eight 28cm (11in) guns. Over the next two years, the design was refined into a larger vessel with twelve of the guns, by which time Britain had launched the all-big-gun battleship HMSDreadnought.[1]
Westfalen was 146.1m (479ft 4in) long, 26.9m (88ft 3in) wide, and had a draft of 8.9m (29ft 2in). She displaced18,873t (18,575 long tons) with a standard load, and 20,535t (20,210 long tons) fully laden. The ship design retained 3-shaft triple expansion engines instead of the more advanced turbine engines. Steam was provided to the engines by twelve coal-fired water-tube boilers, with the addition in 1915 of supplementary oil firing.[2] This machinery was chosen at the request of Admiral Alfred von Tirpitz and the Navy's construction department. The department stated in 1905 that the "use of turbines in heavy warships does not recommend itself."[3] This decision was based solely on cost: at the time, Parsons held a monopoly on steam turbines and required a 1million gold mark royalty fee for every turbine engine. German firms were not ready to begin production of turbines on a large scale until 1910.[4]
SMS Westfalen shortly after completion, circa 1910
The German Imperial Navy (Kaiserliche Marine) ordered Westfalen under the provisional name Ersatz Sachsen as a replacement for SMSSachsen, the lead ship of the elderly Sachsen-class ironclads.[2] The Reichstag secretly approved and provided funds for Nassau and Westfalen at the end of March 1906, but construction on Westfalen was delayed while arms and armor were procured.[10] She was laid down on 12 August 1907 at the AG Weser shipyard in Bremen.[11] As with her sister Nassau, construction proceeded swiftly and secretly; detachments of soldiers guarded both the shipyard and the major contractors who supplied building materials, such as Krupp.[10][12] The ship was launched on 1 July 1908, underwent an initial fitting-out, and then in mid-September 1909 was transferred to Kiel by a crew composed of dockyard workers for a final fitting-out. However, the water level in the Weser River was low at this time of year, so six pontoons had to be attached to the ship to reduce her draft. Even so, it took two attempts before the ship cleared the river.[11]
On 16 October 1909, before commissioned into the fleet, Westfalen along with her sister Nassau participated in a ceremony for the opening of the new third entrance in the Wilhelmshaven Naval Dockyard.[13] Exactly one month later, Westfalen was commissioned for sea trials, which were interrupted only by fleet training exercises in February 1910. At the completion of the trials on 3 May, Westfalen was added to I Battle Squadron of the High Seas Fleet; two days later, she became the squadron flagship, replacing the pre-dreadnought battleshipSMSHannover. The navy had intended to transfer the ship to II Battle Squadron, but this plan was discarded after the outbreak of World War I in July 1914.[11]
World War I
Westfalen participated in most of the fleet advances into the North Sea throughout the war.[11] The first operation was conducted primarily by Rear Admiral Franz von Hipper's battlecruisers; the ships bombarded the English coastal towns of Scarborough, Hartlepool, and Whitby on 15–16 December 1914.[14] A German battlefleet of 12 dreadnoughts, including Westfalen, her three sisters and eight pre-dreadnoughts sailed in support of the battlecruisers. On the evening of 15 December, they 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 the German fleet commander, Admiral Friedrich von Ingenohl, that the entire Grand Fleet was deployed before him. Under orders from Kaiser Wilhelm II, Ingenohl broke off the engagement and turned the battlefleet back towards Germany.[15] In late March 1915 the ship went into drydock for periodic maintenance.[11]
In August 1915, the German fleet attempted to clear the Russian-held Gulf of Riga in order to assist the German army, which was planning an assault on Riga itself. To do so, the German planners intended to drive off or destroy the Russian naval forces in the Gulf, which included the pre-dreadnought battleship Slava and a number of smaller gunboats and destroyers. The German battle fleet was accompanied by several mine-warfare vessels, tasked first with clearing Russian minefields and then laying a series of their own minefields in the northern entrance to the Gulf to prevent Russian naval reinforcements from reaching the area. The assembled German fleet included Westfalen and her three sister ships, the four Helgoland-class battleships, the battlecruisers Von der Tann, Moltke, and Seydlitz, and several pre-dreadnoughts. The force operated under the command of Hipper, who had by now been promoted to vice admiral. The eight battleships were to provide cover for the forces engaging the Russian flotilla. The first attempt on 8 August was broken off, as it took too long to clear the Russian minefields.[16]
On 16 August 1915, a second attempt was made to enter the Gulf: Nassau and Posen, four light cruisers, and 31torpedo boats managed to breach the Russian defenses.[17] On the first day of the assault, two German light craft—the minesweeper T46 and the destroyer V99—were sunk. The following day, Nassau and Posen battled Slava, scoring three hits on the Russian ship that forced her to retreat. By 19 August, the Russian minefields had been cleared and the flotilla entered the Gulf. However, reports of Allied submarines in the area prompted the Germans to call off the operation the following day.[18] Admiral Hipper later remarked that "to keep valuable ships for a considerable time in a limited area in which enemy submarines were increasingly active, with the corresponding risk of damage and loss, was to indulge in a gamble out of all proportion to the advantage to be derived from the occupation of the Gulf before the capture of Riga from the land side." In fact, the battlecruiser Moltke had been torpedoed that morning.[19]
Return to the North Sea
By the end of August Westfalen and the rest of the High Seas Fleet had returned to their anchorages in the North Sea. The next operation conducted was a sweep into the North Sea on 11–12 September, though it ended without any action. Another sortie followed on 23–24 October during which the German fleet did not encounter any British forces. Another uneventful advance into the North Sea took place on 21–22 April 1916. A bombardment mission followed two days later; Westfalen joined the battleship support for Hipper's battlecruisers while they attacked Yarmouth and Lowestoft on 24–25 April.[20] During this operation, the battlecruiser Seydlitz was damaged by a British mine and had to return to port prematurely. Due to poor visibility, the operation was soon called off, leaving the British fleet no time to intercept the raiders.[21]
Admiral Reinhard Scheer, who had succeeded Admirals von Ingenohl and Hugo von Pohl as the fleet commander, immediately planned another attack on the British coast. However, the damage to Seydlitz and condenser trouble on several of the III Battle Squadron dreadnoughts delayed the plan until the end of May 1916.[22] The German battlefleet departed the Jade at 03:30[lower-alpha 4] on 31 May.[23]Westfalen was assigned to II Division of I Battle Squadron, under the command of Rear Admiral W. Engelhardt. Westfalen was the last ship in the division, astern of her three sisters. II Division was the last unit of dreadnoughts in the fleet; they were followed by only the elderly pre-dreadnoughts of II Battle Squadron.[24]
Between 17:48 and 17:52, eleven German dreadnoughts, including Westfalen, engaged and opened fire on the British 2nd Light Cruiser Squadron, though the range and poor visibility prevented effective fire, which was soon checked.[25] At 18:05, Westfalen began firing again; her target was a British light cruiser, most probably the Southampton. Despite the short distance, around 18,000 metres (19,690yd), Westfalen scored no hits.[26] Scheer had by this time called for maximum speed in order to pursue the British ships; Westfalen made 20 knots (37km/h; 23mph).[27] By 19:30 when Scheer signaled "Go west", the German fleet had faced the deployed Grand Fleet for a second time and was forced to turn away. In doing so, the order of the German line was reversed; this would have put II Squadron in the lead, but Captain Redlich of Westfalen noted that II Squadron was out of position and began his turn immediately, assuming the lead position.[28]
Around 21:20, Westfalen and her sister ships began to be engaged by the battlecruisers of the 3rd Battlecruiser Squadron; several large shells straddled (fell to either side of) the ship and rained splinters on her deck. Shortly thereafter, two torpedo tracks were spotted that turned out to be imaginary. The ships were then forced to slow down in order to allow the battlecruisers of I Scouting Group to pass ahead.[29] Around 22:00, Westfalen and Rheinland observed unidentified light forces in the gathering darkness. After flashing a challenge via searchlight that was ignored, the two ships turned away to starboard in order to evade any torpedoes that might have been fired. The rest of I Battle Squadron followed them.[30] During the brief encounter, Westfalen fired seven of her 28cm shells in the span of about two and a half minutes.[31]Westfalen again assumed a position guiding the fleet, this time because Scheer wanted lead ships with greater protection against torpedoes than the pre-dreadnoughts had.[32]
At about 00:30, the leading units of the German line encountered British destroyers and cruisers. A violent firefight at close range ensued; Westfalen opened fire on the destroyer HMSTipperary with her 15cm and 8.8cm guns at a distance of about 1,800m (2,000yd). Her first salvo destroyed Tipperary's bridge and forward deck gun. In the span of five minutes, Westfalen fired ninety-two 15cm and forty-five 8.8cm rounds at Tipperary before turning 90degrees to starboard to evade any torpedoes that might have been fired.[33]Nassau and several cruisers and destroyers joined in the attack on Tipperary; the ship was quickly turned into a burning wreck. The destroyer nevertheless continued to fire with her stern guns and launched her two starboard torpedoes.[34] One of the British destroyers scored a hit on Westfalen's bridge with its 4-inch (10cm) guns, killing two men and wounding eight;[35] Captain Redlich was slightly wounded.[36] At 00:50, Westfalen spotted HMSBroke and briefly engaged her with her secondary guns; in about 45seconds she fired thirteen 15cm and thirteen 8.8cm shells before turning away.[37]Broke was engaged by other German warships, including the cruiser Rostock; she was hit at least seven times and suffered 42dead, six missing, and 34wounded crew members. An officer aboard the light cruiser Southampton described Broke as "an absolute shambles."[38] Despite the serious damage inflicted, Broke managed to withdraw from the battle and reach port.[37] Just after 01:00, Westfalen's searchlights fell on the destroyer Fortune, which was wrecked and set ablaze in a matter of seconds by Westfalen and Rheinland.[39] She also managed to sink the British destroyer Turbulent.[40]
Despite the ferocity of the night fighting, the High Seas Fleet punched through the British destroyer forces and reached Horns Reef by 4:00 on 1 June.[41] With Westfalen in the lead,[42] the German fleet reached Wilhelmshaven a few hours later, where the battleship and two of her sisters took up defensive positions in the outer roadstead.[43] Over the course of the battle, the ship had fired fifty-one 28cm shells, one-hundred and seventy-six 15cm rounds, and one hundred and six 8.8cm shells.[44] Repair work followed immediately in Wilhelmshaven and was completed by 17 June.[45]
Another fleet advance followed on 18–22 August, during which the IScouting Group battlecruisers were to bombard the coastal town of Sunderland in an attempt to draw out and destroy Beatty's battlecruisers. As only two of the four German battlecruisers were still in fighting condition, three dreadnoughts were assigned to the Scouting Group for the operation: Markgraf, Grosser Kurfürst, and the newly commissioned Bayern. The High Seas Fleet, including Westfalen at the rear of the line,[11] would trail behind and provide cover.[46] However, at 06:00 on 19 August, Westfalen was torpedoed by the British submarine HMSE23, some 55 nautical miles (102km; 63mi) north of Terschelling. The ship took in approximately 800 metric tons (790 long tons; 880 short tons) of water, but the torpedo bulkhead held. Three torpedo-boats were detached from the fleet to escort the damaged ship back to port; Westfalen made 14kn (26km/h; 16mph) on the return trip.[11] The British were aware of the German plans and sortied the Grand Fleet to meet them. By 14:35, Admiral Scheer had been warned of the Grand Fleet's approach and, unwilling to engage the whole of the Grand Fleet just 11weeks after the close call at Jutland, turned his forces around and retreated to German ports.[47] Repairs to Westfalen lasted until 26 September.[11]
Following the repair work, Westfalen briefly went into the Baltic Sea for training, before returning to the North Sea on 4 October. The fleet then advanced as far as the Dogger Bank on 19–20 October.[48] The ship remained in port for the majority of 1917. The ship did not actively take part in Operation Albion in the Baltic, though she was stationed off Apenrade to prevent a possible British incursion into the area.[49]
On 22 February 1918, Westfalen and Rheinland were tasked with a mission to Finland to support German army units to be deployed there. The Finns were engaged in a Civil War between the Whites and the Reds. On 23 February, the two ships took on the 14th Jäger Battalion, and early on 24 February they departed for Åland. Åland was to be a forward operating base, from which the port of Hanko would be secured, following an assault on the capital of Helsinki. The task force reached the Åland Islands on 5 March, where they encountered the Swedish coastal defense shipsSverige, Thor, and Oscar II. Negotiations ensued, which resulted in the landing of the German troops on Åland on 7 March; Westfalen then returned to Danzig.[49]
Westfalen remained in Danzig until 31 March, when she departed for Finland with Posen; the ships arrived at Russarö, which was the outer defense for Hanko, by 3 April. The German army quickly took the port. The task force then proceeded to Helsingfors; on 9 April Westfalen stood off Reval, organizing the invasion force. Two days later the ship passed into the harbor at Helsingfors and landed the soldiers; she supported their advance with her main guns. The Red Guards were defeated within three days. The ship remained in Helsingfors until 30 April, by which time the White government had been installed firmly in power.[49]
Following the operation, Westfalen returned to the North Sea where she rejoined I Battle Squadron. On 11 August, Westfalen, Posen, Kaiser, and Kaiserin steamed out towards Terschelling to support German patrols in the area. While en route, Westfalen suffered serious damage to her boilers that reduced her speed to 16kn (30km/h; 18mph). After returning to port, she was decommissioned and employed as an artillery training ship.[49]
Fate
Following the German collapse in November 1918, a significant portion of the High Seas Fleet was interned in Scapa Flow under the terms of the Armistice. Westfalen and her three sisters—the oldest dreadnoughts in the German navy-were not among the ships listed for internment, so they remained in German ports.[50] During the internment, a copy of The Times informed the German commander, Rear Admiral Ludwig von Reuter, that the Armistice was to expire at noon on 21 June 1919, the deadline by which Germany was to have signed the peace treaty. Reuter believed that the British intended to seize the German ships after the Armistice expired.[lower-alpha 5] To prevent this, he decided to scuttle his ships at the first opportunity. On the morning of 21 June, the British fleet left Scapa Flow to conduct training maneuvers; at 11:20 Reuter transmitted the order to his ships.[52]
As a result of the scuttling at Scapa Flow, the Allies demanded replacements for the ships that had been sunk. Westfalen was struck from the German naval list on 5 November 1919 and subsequently handed over to the Allies under the contract name "D" on 5 August 1920.[53] The ship was then sold to ship-breakers in Birkenhead, where she was broken up for scrap by 1924.[49]
↑ In Imperial German Navy gun nomenclature, "SK" (Schnelladekanone) denotes that the gun quick firing, while "L/45" provides the length of the gun regarding the diameter of the barrel. In this case, the L/45 gun is 45 caliber, which means that the gun is 45times as long as its diameter.[5]
↑ Four of the six gun turrets were arranged as wing turrets, two on either side of the superstructure, a compact arrangement that reduced the length of the ship.[6] No foreign dreadnought at that time used this arrangement. HMSDreadnought carried two wing turrets and three more on the centerline, while USSSouth Carolina mounted all four turrets in superfiring pairs on the centerline. The first Russian (Gangut) and Italian (Dante Alighieri) designs carried four gun turrets on the centerline.[7]
↑ The times used in this article are in CET, which is one hour ahead of UTC, which is often used in British works.
↑ By this time, the Armistice had been extended to 23 June, though there is some contention as to whether Reuter was aware of this. Admiral Sydney Fremantle stated that he informed Reuter on the evening of the 20th,[51] though Reuter claims he was unaware of the development.[52]
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 Helgoland, the lead ship of her class, was a dreadnought battleship of the German Imperial Navy. Helgoland's design represented an incremental improvement over the preceding Nassau class, including an increase in the bore diameter of the main guns, from 28 cm (11 in) to 30.5 cm (12 in). Her keel was laid down on 11 November 1908 at the Howaldtswerke shipyards in Kiel. Helgoland was launched on 25 September 1909 and was commissioned on 23 August 1911.
SMS Pommern was one of five Deutschland-class pre-dreadnought battleships built for the Kaiserliche Marine between 1904 and 1906. Named after the Prussian province of Pomerania, she was built at the AG Vulcan yard at Stettin, Germany, where she was laid down on 22 March 1904 and launched on 2 December 1905. She was commissioned into the navy on 6 August 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 the service, being inferior in size, armor, firepower, and speed to the revolutionary new battleship HMS Dreadnought.
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 Posen was one of four battleships in the Nassau class, the first dreadnoughts built for the German Imperial Navy. The ship was laid down at the Germaniawerft shipyard in Kiel on 11 June 1907, launched on 12 December 1908, and commissioned into the High Seas Fleet on 31 May 1910. She was equipped with a main battery of twelve 28 cm (11 in) guns in six twin turrets in an unusual hexagonal arrangement.
SMS Rheinland was one of four Nassau-class battleships, the first dreadnoughts built for the German Imperial Navy. Rheinland mounted twelve 28 cm (11 in) main guns in six twin turrets in an unusual hexagonal arrangement. The navy built Rheinland and her sister ships in response to the revolutionary British HMS Dreadnought, which had been launched in 1906. Rheinland was laid down in June 1907, launched the following year in October, and commissioned in April 1910.
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.
The Helgoland class was the second class of dreadnought battleships to be built for the German Kaiserliche Marine. Constructed from 1908 to 1912, the class comprised four ships: Helgoland, the lead ship; Oldenburg; Ostfriesland; and Thüringen. The design was a significant improvement over the previous Nassau-class ships; they had a larger main battery—30.5 cm (12 in) main guns instead of the 28 cm (11 in) weapons mounted on the earlier vessels—and an improved propulsion system. The Helgolands were easily distinguished from the preceding Nassaus by the three funnels that were closely arranged, compared to the two larger funnels of the previous class. The ships retained the hexagonal main battery layout of the Nassau class.
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 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 Kaiserin was the third vessel of the Kaiser class of dreadnought battleships of the Imperial German Navy. Kaiserin'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 30.5-centimeter (12 in) guns in five twin turrets, and had a top speed of 22.1 knots. Kaiserin 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.
SMS Ostfriesland was the second vessel of the Helgoland class of dreadnought battleships of the Imperial German Navy. Named for the region of East Frisia, Ostfriesland's keel was laid in October 1908 at the Kaiserliche Werft dockyard in Wilhelmshaven. She was launched on 30 September 1909 and was commissioned into the fleet on 1 August 1911. The ship was equipped with twelve 30.5 cm (12 in) guns in six twin turrets, and had a top speed of 21.2 knots. Ostfriesland was assigned to the I Battle Squadron of the High Seas Fleet for the majority of her career, including World War I.
SMS Oldenburg was the fourth vessel of the Helgoland class of dreadnought battleships of the Imperial German Navy. Oldenburg's keel was laid in March 1909 at the Schichau-Werke dockyard in Danzig. She was launched on 30 June 1910 and was commissioned into the fleet on 1 May 1912. The ship was equipped with twelve 30.5 cm (12 in) guns in six twin turrets, and had a top speed of 21.2 knots. Oldenburg was assigned to I Battle Squadron of the High Seas Fleet for the majority of her career, including World War I.
SMS Thüringen was the third vessel of the Helgoland class of dreadnought battleships of the German Kaiserliche Marine (Imperial Navy}. Thüringen's keel was laid in November 1908 at the AG Weser dockyard in Bremen. She was launched on 27 November 1909 and commissioned into the fleet on 1 July 1911. The ship was equipped with twelve 30.5 cm guns in six twin turrets, and had a top speed of 21 knots. Thüringen was assigned to I Battle Squadron of the High Seas Fleet for the majority of her career, including World War I.
