SMS Bayern was the lead vessel of the Bayern class of dreadnought battleships built for the German Kaiserliche Marine during World War I. Launched in February 1915 and commissioned in July 1916, Bayern was a formidable warship featuring significant advancements over earlier German battleships. Its main armament comprised eight 38 cm (15-inch) SK L/45 guns arranged in four twin turrets—two superfiring fore and aft—marking a substantial upgrade from the previous 30.5 cm (12-inch) guns. The ship's secondary weaponry included sixteen 15 cm guns, four 8.8 cm anti-aircraft guns, and five underwater torpedo tubes. The armor was substantial, with a belt thickness ranging from 170 to 350 mm (6.7 to 13.8 inches), and armored decks 60 to 100 mm (2.4 to 3.9 inches) thick, providing considerable protection for its vital areas. Constructed at Howaldtswerke in Kiel, Bayern measured approximately 179.4 meters (588 feet 7 inches) in waterline length and 180 meters (590 feet 7 inches) overall, with a beam of 30 meters (98 feet 5 inches) and a draft of about 9.3–9.4 meters (30 ft 6 in – 30 ft 10 in). Displacing around 28,530 metric tons at normal load and up to 32,200 tons at full combat load, Bayern was powered by three Parsons steam turbines fueled by coal and oil-fired boilers, capable of reaching speeds up to 22 knots (41 km/h; 25 mph). Its range was approximately 5,000 nautical miles at 12 knots, allowing for extended operations. Bayern’s service history was limited by timing; she entered active duty too late to participate in the Battle of Jutland. Her notable engagements included an abortive North Sea fleet advance in August 1916, participation in Operation Albion in the Gulf of Riga—where she was mined and damaged— and later, in October 1917, she supported the Baltic campaign, firing upon Russian shore batteries before being withdrawn for repairs. She served briefly as a fleet flagship in August 1916 and later as part of fleet operations aimed at disrupting British convoys and engaging Russian forces. Following Germany’s defeat, Bayern was interned at Scapa Flow in November 1918. Under the orders of Rear Admiral Ludwig von Reuter, she was scuttled on 21 June 1919 to prevent her from being seized by the Allies. The ship was later raised in 1934 and scrapped at Rosyth. Parts of her remain on the sea floor, and her main battery turrets are accessible to divers, symbolizing her role in the naval arms race and the strategic limitations faced by Germany during the war.
