SMS Gneisenau[a] was an armored cruiser of the German Kaiserliche Marine (Imperial Navy), part of the two-ship Scharnhorst class. Named for the earlier screw corvette of the same name, the ship was laid down in June 1904 at the AG Weser shipyard in Bremen, launched in June 1906, and commissioned in March 1908. She was armed with a main battery of eight 21 cm (8.3 in) guns, a significant increase in firepower over earlier German armored cruisers, and she had a top speed of 22.5 knots (42 km/h; 26 mph). Gneisenau initially served with the German fleet in I Scouting Group, though her service there was limited owing to the British development of the battlecruiser by 1909, which the less powerful armored cruisers could not effectively combat.

Accordingly, Gneisenau was assigned to the German East Asia Squadron, where she joined her sister ship Scharnhorst. The two cruisers formed the core of the squadron, which included several light cruisers. Over the next four years, Gneisenau patrolled Germany's colonial possessions in Asia and the Pacific Ocean. She also toured foreign ports to show the flag and monitored events in China during the Xinhai Revolution in 1911. Following the outbreak of World War I in July 1914, the East Asia Squadron, under the command of Vice Admiral Maximilian von Spee, crossed the Pacific to the western coast of South America, stopping for Gneisenau and Scharnhorst to attack French Polynesia in the Bombardment of Papeete in September.

After arriving off the coast of Chile, the East Asia Squadron encountered and defeated a British squadron at the Battle of Coronel; during the action, Gneisenau disabled the British armored cruiser HMS Monmouth, which was then sunk by the German light cruiser Nürnberg. The defeat prompted the British Admiralty to detach two battlecruisers to hunt down and destroy Spee's squadron, which they accomplished at the Battle of the Falkland Islands on 8 December 1914. Gneisenau was sunk with heavy loss of life, though 187 of her crew were rescued by the British.

The ship had four smoke stacks between a pair of tall pole masts. A twin gun turret was positioned on either end of the superstructure, which bristled with guns
Line-drawing of the Scharnhorst class

The two Scharnhorst-class cruisers were ordered as part of the naval construction program laid out in the Second Naval Law of 1900, which called for a force of fourteen armored cruisers. The ships marked a significant increase in combat power over their predecessors, the Roon class, being more heavily armed and armored. These improvements were made to allow for Scharnhorst and Gneisenau to fight in the line of battle should the need arise, a capability requested by the General Department.[1]

Gneisenau was 144.6 meters (474 ft 5 in) long overall, and had a beam of 21.6 m (70 ft 10 in) and a draft of 8.37 m (27 ft 6 in). The ship displaced 11,616 metric tons (11,433 long tons) normally, and 12,985 t (12,780 long tons) at full load. Gneisenau's crew consisted of 38 officers and 726 enlisted men. The ship was powered by three triple-expansion steam engines, each driving a screw propeller, with steam provided by eighteen coal-fired water-tube boilers. The boilers were ducted into four funnels located amidships. Her propulsion system was rated to produce 26,000 metric horsepower (19,000 kW) for a top speed of 22.5 knots (42 km/h; 26 mph). She had a cruising radius of 4,800 nautical miles (8,900 km; 5,500 mi) at a speed of 14 knots (26 km/h; 16 mph).[2]

Gneisenau's primary armament consisted of eight 21 cm (8.3 in) SK L/40 guns,[b] four in twin gun turrets, one fore and one aft of the main superstructure on the centerline, and the remaining four mounted in single casemates in the hull at main deck level, abreast the funnels. The secondary armament included six 15 cm (5.9 in) SK L/40 guns, also in individual casemates that were placed a deck below the main battery casemates. Defense against torpedo boats was provided by a battery of eighteen 8.8 cm (3.5 in) SK L/35 guns mounted in casemates. She was also equipped with four 45 cm (17.7 in) submerged torpedo tubes. One was mounted in the bow, one on each broadside, and the fourth was placed in the stern.[2]

The ship was protected by a 15 cm belt of Krupp armor, decreased to 8 cm (3.1 in) forward and aft of the central citadel. She had an armored deck that was 3.5 to 6 cm (1.4 to 2.4 in) thick, with the heavier armor protecting the ship's engine and boiler rooms and ammunition magazines. The centerline gun turrets had 17 cm (6.7 in) thick sides, while the casemate main guns received 15 cm of armor protection. The casemate secondary battery was protected by a strake of armor that was 13 cm (5.1 in) thick.[2][4]
