SMS Bayern was a Sachsen-class armored frigate of the German Kaiserliche Marine, built by the Kaiserliche Werft in Kiel between 1874 and 1881. She measured 98.2 meters (322 feet 2 inches) in length overall, with a beam of 18.4 meters (60 feet 4 inches) and a draft of 6.32 meters (20 feet 9 inches). Displacing approximately 7,742 tons at full load, Bayern was powered by two 3-cylinder single-expansion steam engines fueled by eight coal-fired Dürr boilers, venting through four distinctive square funnels. Her top speed was 13 knots (24 km/h), powered by 5,600 metric horsepower. The ship's main armament comprised six 26 cm (10.2 inch) guns—two in open barbettes forward and four amidships—designed for heavy firepower. She also carried six 8.7 cm guns and eight 3.7 cm Hotchkiss revolver cannons for defense against torpedo boats. Her armor was wrought iron, with a heavily armored citadel amidships up to 254 mm (10 inches) thick, and deck armor ranging from 50 to 75 mm (2–3 inches). The barbette armor was similarly robust, at 254 mm backed by 250 mm of teak. Launched on 13 May 1878 and commissioned on 4 August 1881, Bayern's early service was marked by periods of reserve due to issues with her sister ships, notably poor seakeeping and low speed. She saw active duty from 1884, participating in fleet exercises, cruises, and diplomatic visits, including escorting Kaiser Wilhelm II on state visits. Throughout the 1880s and 1890s, Bayern served as a flagship and participated in various fleet maneuvers, often acting as the flagship of different divisions. In 1895–1898, Bayern underwent a major modernization at Schichau-Werke, receiving new Krupp nickel-steel armor, upgraded engines boosting her speed to 15.4 knots, and modern quick-firing guns. After her refit, she served in the fleet until she was decommissioned in 1910. Subsequently, Bayern was used as a target ship, notably during the Kiel flight week of 1913, where aircraft scored hits on her. She remained in service as a floating target through World War I and was ultimately sold for scrap in 1919. Bayern's career reflected Germany's naval development during a period of evolving maritime strategy and technological innovation.
