SMS Siegfried was the lead vessel of the Siegfried class of coastal defense ships built for the German Imperial Navy between 1888 and 1890. Constructed by Germaniawerft in Kiel, she measured 79 meters (259 feet) in length overall, with a beam of 14.9 meters (48.9 feet) and a maximum draft of 5.74 meters (18.8 feet). Her displacement was approximately 3,500 tons normally, increasing to around 3,741 tons at full load. The ship's hull featured a long forecastle deck extending most of her length and a pronounced ram bow, emphasizing her coastal defense role. Propulsion was provided by two vertical 3-cylinder triple-expansion engines, marking her as the first major German warship powered by this machinery type. Steam was produced by four coal-fired fire-tube boilers vented through a single funnel, giving her a top speed of 14.9 knots and a range of about 1,490 nautical miles at 10 knots. Armament included a main battery of three 24 cm (9.4 in) guns, mounted in three single turrets—two side-by-side forward and one aft—supplying 204 rounds. For defense against smaller vessels, she carried six 8.8 cm (3.5 in) guns and was equipped with four 35 cm (13.8 in) torpedo tubes, with configurations at the bow, stern, and amidships. Her armor consisted of a 240 mm (9.4 in) belt in the central citadel, an armored deck 30 mm thick, and an 80 mm (3.1 in) thick conning tower. Siegfried underwent a significant reconstruction in 1903-1904, extending her length to 86.13 meters (282.6 feet), upgrading her boilers to water-tube types, and increasing her speed to 15.3 knots. Her armament was also enhanced, with her secondary guns increased to ten 8.8 cm and her torpedo armament upgraded to three 45 cm tubes. Her service included active participation in fleet maneuvers, guard duties, and occasional Mediterranean cruises in her early years. During World War I, she served primarily in harbor defense and patrol duties, stationed at Jade Bay and Weser. Decommissioned in 1916, she was later used as a barracks and support ship until being stricken in 1919. Ultimately, SMS Siegfried was sold for scrap in 1920, ending her maritime career as a symbol of Germany's coastal defense efforts at the turn of the 20th century.
