The SMS Grosser Kurfürst was an ironclad turret ship constructed for the German Kaiserliche Marine, representing the first class of uniform ironclads built for Germany. Laid down at the Imperial Dockyard in Wilhelmshaven around 1869-1870 and launched on September 17, 1875, the vessel was completed in 1878 after a lengthy construction period influenced by redesigns, political delays, and inexperience at the shipyard. She measured approximately 96.6 meters (317 feet) in length overall, with a beam of 16.3 meters (53.5 feet) and a draft of 7.12 meters (23.4 feet). Her propulsion system included a single 3-cylinder single-expansion steam engine, which drove a single screw propeller, powered by six coal-fired transverse trunk boilers. This machinery allowed her to reach a top speed of around 14 knots (26 km/h). She also carried a full ship rig of sails for auxiliary propulsion. Armament comprised four 26 cm (10-inch) L/22 guns mounted in twin turrets amidships, which was a redesign from the original plan of a central armored battery. She also had two 17 cm (6.7-inch) RK L/25 chase guns, one fore and one aft. Her armor was constructed of wrought iron backed with teak, with the belt consisting of two strakes—an upper strake 203 mm (8 inches) thick and a lower strake ranging from 102 to 229 mm (4 to 9 inches)—all backed by 234 to 260 mm (9.2 to 10.2 inches) of teak. The gun turrets were protected by armor up to 254 mm (10 inches) thick, with additional teak backing. Tragically, Grosser Kurfürst sank on her maiden voyage on May 31, 1878, after being accidentally rammed by her sister ship, SMS König Wilhelm, in the English Channel. During a maneuver to avoid sailing vessels, König Wilhelm's ram bow tore a large hole in Grosser Kurfürst’s hull, leading to rapid flooding and her sinking within approximately fifteen minutes. The disaster resulted in the loss of between 269 and 284 crew members, with many bodies buried in Folkestone. The incident prompted multiple investigations and court martials, ultimately attributing fault to negligence and inadequate crew training. The sinking had significant repercussions for German naval policy, highlighting the need for more thorough crew preparation and influencing subsequent naval reforms. The wreck remains a memorial site and was designated as a scheduled monument in 2020, reflecting its maritime historical importance.
