SMS Heimdall was the fourth vessel of the six-member Siegfried class of coastal defense ships (Küstenpanzerschiffe) built for the German Imperial Navy. Her sister ships were Siegfried, Beowulf, Frithjof, Hildebrand, and Hagen. Heimdall was built by the Kaiserliche Werft Wilhelmshaven shipyard between 1891 and 1894, and was armed with a main battery of three 24-centimeter (9.4 in) guns. She served in the German fleet throughout the 1890s and was rebuilt in 1900–1902. She served in the VI Battle Squadron after the outbreak of World War I in August 1914, but saw no action. Heimdall was demobilized in 1915 and used as a barracks ship thereafter. She was ultimately broken up for scrap in 1921.
Heimdall was 79 meters (259 ft) long overall and had a beam of 14.9 m (49 ft) and a maximum draft of 5.74 m (18.8 ft). She displaced 3,741 long tons (3,801 t) at full combat load. Her propulsion system consisted of two vertical 3-cylinder triple expansion engines. Steam for the engines was provided by four coal-fired boilers. The ship's propulsion system provided a top speed of 14.6 kn (27.0 km/h; 16.8 mph) and a range of approximately 1,490 nautical miles (2,760 km; 1,710 mi) at 10 kn (19 km/h; 12 mph). Heimdall had a crew of 20 officers and 256 enlisted men.
The ship was armed with three 24 cm K L/35 guns mounted in three single gun turrets. Two were placed side by side forward, and the third was located aft of the main superstructure. They were supplied with a total of 204 rounds of ammunition. The ship was also equipped with eight 8.8 cm SK L/30 guns in single mounts. Heimdall also carried four 35 cm (14 in) torpedo tubes, all in swivel mounts on the deck. One was at the bow, another at the stern, and two amidships. The ship was protected by an armored belt that was 240 mm (9.4 in) amidships, and an armored deck that was 30 mm (1.2 in) thick. The conning tower had 80 mm (3.1 in) thick sides.Heimdall's armor consisted of new Krupp steel, a more effective type of armor than the compound steel the other members of the class received.
