SMS Template:Efn was the lead ship of the Template:Sclass of dreadnought battleships in the German (Imperial Navy). The vessel was launched in February 1915 and entered service in July 1916, too late to take part in the Battle of Jutland. Her main armament consisted of eight 38 cm (15 in) guns in four turrets, which was a significant improvement over the preceding Template:SclassTemplate:'s ten 30.5 cm (12 inch) guns.Template:Efn The ship was to have formed the nucleus for a fourth battle squadron in the High Seas Fleet, along with three of her sister ships. Of the other ships only one—Template:SMS—was completed; the other two were canceled later in the war when production requirements shifted to U-boat construction.

was commissioned midway through the war, and had a limited service career. The first operation in which the ship took part was an abortive fleet advance into the North Sea on 18–19 August 1916, a month after she had been commissioned. The ship also participated in Operation Albion in the Gulf of Riga, but shortly after the German attack began on 12 October 1917, was mined and had to be withdrawn for repairs. She was interned with the majority of the High Seas Fleet at Scapa Flow in November 1918 following the end of World War I. On 21 June 1919, Admiral Ludwig von Reuter ordered the fleet to be scuttled; sank at 14:30. In September 1934, the ship was raised, towed to Rosyth, and scrapped.

Design work on the class began in 1910 in the context of the Anglo-German naval arms race, with initial discussions focused on the caliber of the main battery; previous German battleships had carried Template:Cvt guns, but as foreign navies adopted Template:Cvt and Template:Cvt weapons, the German naval command felt the need to respond with larger guns of their own. They considered Template:Cvt, Template:Cvt, and Template:Cvt guns. Admiral Alfred von Tirpitz, the State Secretary of the (Imperial Naval Office), was able to use public outcry over the Agadir Crisis to pressure the (Imperial Diet) into appropriating additional funds for the (Imperial Navy) to offset the additional cost of the larger weapons. The design staff settled on the 38 cm caliber since the 40 cm was significantly more expensive and the 38 cm gun marked a significant improvement over existing German guns.Template:SfnTemplate:SfnTemplate:Sfn

was Template:Convert long at the waterline, and an even Template:Convert long overall. She had a beam of Template:Convert and a draft of Template:Convert displaced Template:Convert at a normal displacement; at full combat load, she displaced up to Template:Convert. was powered by three Parsons steam turbines, with steam provided by three oil-fired and eleven coal-fired Schulz-Thornycroft water-tube boilers. Her propulsion system was rated at Template:Convert for a maximum speed of Template:Convert, and on trials achieved Template:Convert for a maximum speed of Template:Convert.Template:SfnTemplate:Efn The ship could carry up to Template:Convert of coal and Template:Convert of fuel oil, which provided a maximum range of Template:Convert at a cruising speed of Template:Convert.Template:Sfn

The ship was the first German warship armed with eight [[38 cm SK L/45 gun|Template:Convert SK L/45]] guns.Template:Efn The main battery guns were arranged in four twin gun turrets: two superfiring turrets each fore and aft.Template:Sfn Her secondary armament consisted of sixteen [[15 cm SK L/45|Template:Convert SK L/45]] guns, four [[8.8 cm SK L/45 naval gun|Template:Convert SK L/45]] guns and five 60 cm (23.6 in) underwater torpedo tubes, one in the bow and two on each beam. Upon commissioning, she carried a crew of 42 officers and 1,129 enlisted men. The ship had an armored belt that was Template:Convert thick and an armored deck that was Template:Convert thick. Her forward conning tower had Template:Convert sides, and the main battery turrets had 350 mm thick sides and Template:Convert thick roofs.Template:SfnTemplate:Sfn

was ordered with the provisional name "T" in 1912,Template:SfnTemplate:Efn under the fourth and final Naval Law, which was passed that year.Template:Sfn Work began at the Howaldtswerke Dockyard in Kiel under construction number 590. The ship was laid down on 22 December 1913 and launched on 18 February 1915. After fitting out, she was commissioned on 18 March 1916, but remained largely idle in port for the next month, undergoing initial tests, including inclination tests to determine how the vessel responded to flooding. She got underway on 15 April for initial trials of her main battery, which lasted into the next day. conducted her first full-power speed test on 25 April off the island of Alsen; these trials continued until 2 May. After further examinations, the ship was deemed ready for service on 15 July, a month and a half too late for her to participate in the Battle of Jutland.Template:SfnTemplate:Sfn

joined III Battle Squadron of the High Seas Fleet upon her commissioning. The ship would have been available for the operation,Template:Sfn but the ship's crew, composed largely of the crew from the recently decommissioned battleship Template:SMS,Template:Sfn was given leave.Template:Sfn She had cost the Imperial German Government 49 million Goldmarks.Template:Sfn was later joined in service by one sister ship, Template:SMS. Two other ships of this class, and , were canceled before they were completed.Template:Sfn At the time of her commissioning, Template:'s commander was (Captain at Sea) Max Hahn. Ernst Lindemann, who went on to command the battleship during her only combat sortie in World War II, served aboard the ship as a wireless operator.Template:Sfn On 25 May, Ludwig III of Bavaria, the last King of Bavaria, visited the ship. briefly served as the fleet flagship, from 7 to 16 August.Template:Sfn

Admiral Reinhard Scheer planned a fleet advance for 18–19 August 1916; the operation consisted of a bombardment conducted by I Scouting Group. This was an attempt to draw out and destroy Admiral David Beatty's battlecruisers. As Template:SMS and Template:SMS were the only two German battlecruisers still in fighting condition, three dreadnoughts were assigned to the unit for the operation: and the two Template:Sclass ships Template:SMS and Template:SMS. Admiral Scheer and the rest of the High Seas Fleet, including 15 dreadnoughts, were to trail behind and provide cover.Template:Sfn The makeshift I Scouting Group conducted familiarization exercises on 15 August in preparation for the operation; Admiral Franz von Hipper was displeased by the slow speed of the battleships and Scheer ordered the unit not to exceed Template:Convert from the main fleet so as to avoid being cut off by the faster British battlecruisers.Template:Sfn

The Germans got underway late in the day on 18 August; the British were aware of the German plans and sortied the Grand Fleet to meet them. By 14:35 on 19 August,Template:Efn Scheer had been warned of the Grand Fleet's approach and, unwilling to engage the whole of the Grand Fleet just 11 weeks after the close call at Jutland, turned his forces around and retreated to German ports.Template:Sfn Another sortie into the North Sea followed on 18–20 October, and the German fleet again encountered no British naval forces.Template:Sfn The High Seas Fleet was reorganized on 6 December, and was stationed in the second position of III Squadron, since she was not outfitted to serve as a squadron flagship. Her placement as the second vessel in the line nevertheless would have allowed her to bring her greater firepower into action as quickly as possible.Template:Sfn

Operation Albion

In early September 1917, following the German conquest of the Russian port of Riga, the German navy decided to evict the Russian naval forces that still held the Gulf of Riga. To this end, the (the Navy High Command) planned an operation to seize the Baltic islands of Ösel, particularly the Russian gun batteries on the Sworbe peninsula.Template:Sfn On 18 September, the order was issued for a joint Army-Navy operation to capture Ösel and Moon islands; the primary naval component consisted of the flagship and III Battle Squadron of the High Seas Fleet. At this time, V Division included the and four -class battleships. VI Division consisted of the five Template:Sclasss. Along with 9 light cruisers, 3 torpedo boat flotillas, and dozens of mine warfare ships, the entire force numbered some 300 ships, supported by over 100 aircraft and 6 zeppelins. The invasion force amounted to approximately 24,600 officers and enlisted men.Template:Sfn Opposing the Germans were the old Russian pre-dreadnoughts and , the armored cruisers , , and , 26 destroyers, and several torpedo boats and gunboats. The garrison on Ösel numbered some 14,000 men.Template:Sfn

The operation began on 12 October, when , along with and the four s, began firing on the Russian shore batteries at Tagga Bay. Simultaneously, the five s engaged the batteries on the Sworbe peninsula; the objective was to secure the channel between Moon and Dagö islands, thus blocking the only escape route of the Russian ships in the gulf. Template:'s role in the operation was cut short when she struck a naval mine at 5:07 while moving into her bombardment position at Pamerort.Template:Sfn The mine explosion killed one and six sailors, allowed Template:Convert of water into the ship and caused the forecastle to sink by Template:Convert.Template:SfnTemplate:Sfn Despite the damage inflicted by the mine, engaged the naval battery at Cape Toffri on the southern tip of Hiiumaa. was released from her position at 14:00. Preliminary repairs were made on 13 October in Tagga Bay.Template:Sfn The temporary repairs proved ineffective, and had to be withdrawn to Kiel for repairs; the return trip took 19 days.Template:Sfn Repairs lasted from 3 November to 27 December,Template:Sfn during which the forward torpedo tube room was stripped of its equipment and the torpedo ports were sealed. The room was then turned into an additional watertight compartment.Template:Sfn Four [[8.8 cm SK L/30 naval gun|Template:Convert SK L/30]] anti-aircraft guns were also installed during the repairs.Template:Sfn

On 16 October, two -class battleships and several smaller vessels were sent to engage the Russian battleships in the Gulf of Riga. The following day, Template:SMS and Template:SMS engaged the Russian battleships— dueled with and fired on both and the cruiser . The Russian vessels were hit dozens of times, until at 10:30 the Russian naval commander, Admiral Bakhirev, ordered their withdrawal. had taken too much damage, and was unable to escape; instead, she was scuttled and her crew was evacuated on a destroyer.Template:Sfn By 20 October, the naval operations were effectively over; the Russian fleet had been destroyed or forced to withdraw, and the German army held the islands in the gulf.Template:Sfn

Subsequent operations

Following her return to the fleet, was assigned to security duties in the North Sea.Template:Sfn Admiral Scheer had used light surface forces to attack British convoys to Norway beginning in late 1917. As a result, the Royal Navy attached a squadron of battleships to protect the convoys, which presented Scheer with the possibility of destroying a detached squadron of the Grand Fleet. Scheer remarked that "A successful attack on such a convoy would not only result in the sinking of much tonnage, but would be a great military success, and would ... force the English to send more warships to the northern waters."Template:Sfn Scheer instituted strict wireless silence in preparation for the planned attack. This denied the British the ability to intercept and decrypt German signals, which had previously been a significant advantage. The operation called for Hipper's battlecruisers to attack the convoy and its escorts on 23 April while the battleships of the High Seas Fleet stood by in support.Template:Sfn

On 22 April, and the rest of the German fleet assembled in the Schillig Roads outside Wilhelmshaven and departed the following morning at 06:00. Heavy fog forced the Germans to remain inside their defensive minefields for half an hour.Template:Sfn Hipper's forces were Template:Convert west of Egerö, Norway, by 05:20 on 24 April. Despite the success in reaching the convoy route undetected, the operation failed due to faulty intelligence. Reports from U-boats indicated to Scheer that the convoys sailed at the start and middle of each week, but a west-bound convoy had left Bergen on Tuesday the 22nd and an east-bound group left Methil, Scotland, on the 24th, a Thursday. As a result, there was no convoy for Hipper to attack.Template:Sfn

The same day, one of Template:'s screws slipped off, which caused serious damage to the power plant and allowed Template:Convert of water into the ship. was forced to break radio silence in order to inform Scheer of the ship's condition, which alerted the Royal Navy to the High Seas Fleet's activities.Template:Sfn Beatty sortied with a force of 31 battleships and four battlecruisers, but was too late to intercept the retreating Germans. The Germans reached their defensive minefields early on 25 April, though approximately Template:Convert off Helgoland was torpedoed by the submarine Template:HMS. nevertheless successfully returned to port.Template:Sfn

Fate

sinking at Scapa Flow

From 23 September to early October, served as the flagship of III Squadron, under (Vice Admiral) Hugo Kraft.Template:Sfn was to have taken part in what would have amounted to the "death ride" of the High Seas Fleet shortly before the end of World War I. 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 of the fleet—intended to inflict as much damage as possible on the British navy, in order to obtain a better bargaining position for Germany, whatever the cost to the fleet.Template:Sfn

While the fleet was consolidating in Wilhelmshaven, war-weary sailors began rioting.Template:Sfn On 24 October 1918, the order was given to sail from Wilhelmshaven. Starting on the night of 29 October, sailors on several battleships mutinied; three ships from III Squadron refused to weigh anchor, and acts of sabotage were committed on board the battleships Template:SMS and Template:SMS. The order to sail was rescinded in the face of this open revolt.Template:Sfn In an attempt to suppress the mutiny, the battleship squadrons were dispersed.Template:Sfn , along with the rest of III Squadron, was sent to Kiel.Template:Sfn

Following the capitulation of Germany in November 1918, the majority of the High Seas Fleet was to be interned in the Royal Navy base at Scapa Flow.Template:Sfn was listed as one of the ships to be handed over. On 21 November 1918, the ships to be interned, under the command of Rear Admiral Ludwig von Reuter, sailed from their base in Germany for the last time. The fleet rendezvoused with the British light cruiser Template:HMS, before meeting a flotilla of 370 British, American, and French warships for the voyage to Scapa Flow.Template:Sfn

The fleet remained in captivity during the negotiations that ultimately produced the Versailles Treaty. Reuter believed that the British intended to seize the German ships on 21 June, which was the deadline for Germany to have signed the peace treaty. Unaware that the deadline had been extended to the 23rd, Reuter ordered his ships to be sunk. 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.Template:Sfn sank at 14:30. The ship was raised on 1 September 1934 and was broken up the following year in Rosyth. The ship's bell was eventually delivered to the German Federal Navy and is on display at Kiel Fördeklub.Template:SfnTemplate:Efn Some parts of the ship, including her main battery gun turrets, remain on the sea floor between Template:Cvt, where they can be accessed by scuba divers.Template:Sfn
