Dresden-class cruiser explained

The German: Dresden class was a pair of light cruisers built for the Imperial German Navy in the early part of the 20th century. The class comprised, the lead ship, and . Both ships were laid down in 1906; German: Dresden was launched in 1907, and German: Emden followed in 1908. They entered service in 1908 and 1909, respectively. The design for the ships was an incremental improvement over the preceding, being slightly larger and slightly faster, but with the same primary armament of ten 10.5cm (04.1inches) guns. German: Dresden and German: Emden were powered by steam turbines and triple expansion engines, respectively, as part of continued experiments with the new turbine technology.

Both ships served extensively on foreign stations; German: Emden was assigned to the East Asia Squadron from her commissioning, and German: Dresden was sent to Caribbean waters in 1913. German: Dresden was due to return to Germany for periodic maintenance shortly before the outbreak of World War I in August 1914, but this became impossible with the onset of hostilities. She therefore operated as a commerce raider, before linking up with German: [[Vizeadmiral]] Maximilian von Spee's East Asia Squadron. German: Dresden thereafter participated in the Battle of Coronel in November 1914 and the Battle of the Falkland Islands the following December. She was the only German vessel to escape destruction at the latter engagement, and she remained at large for several more months. German: Dresden finally put into the Chilean island of Más a Tierra in March 1915 owing to worn-out engines. A pair of British cruisers violated Chilean neutrality and attacked German: Dresden while she lay at anchor; the Germans scuttled their ship to prevent her capture.

German: Emden, meanwhile, had been detached from the East Asia Squadron to pursue an independent commerce raiding campaign in the Indian Ocean. She captured or sank numerous Entente vessels, including the steamer Russian: [[SMS Cormoran (1909)|Ryazan]], which was converted into the auxiliary cruiser German: Cormoran. In September 1914, German: Emden raided Penang and caught the Russian protected cruiser and the French destroyer and quickly destroyed both ships. Shortly thereafter, German: Emden was caught by the Australian cruiser off the Cocos Islands and forced to beach after a ferocious engagement.

Design

The 1898 Naval Law authorized the construction of thirty new light cruisers; the program began with the, which was developed into the and es, both of which incorporated incremental improvements over the course of construction. The two ships of the German: Dresden class were ordered in the 1905–1906 construction program. Their design represented an incremental improvement over the earlier German: Königsberg class. They carried the same main battery of 10.5cm (04.1inches) guns on a slightly greater displacement with an additional boiler for the propulsion system to increase engine power. Like the German: Königsbergs, one ship—German: Dresden—was fitted with a steam turbine engine to compare its performance with the traditional triple-expansion engine in an otherwise-identical sister ship. All subsequent designs of German cruisers utilized turbine propulsion systems.

General characteristics and machinery

The two German: Dresden-class cruisers were 117.9m (386.8feet) long at the waterline and 118.3m (388.1feet) long overall. They had a beam of 13.5m (44.3feet) and a draft of 5.53m (18.14feet) forward. They displaced 3664sp=usNaNsp=us as designed and up to 4268sp=usNaNsp=us at full load. Their hulls were constructed with transverse and longitudinal steel frames. The hulls contained thirteen watertight compartments and had a double bottom that extended for 47 percent of the length of the keel.

The ships were good sea boats, but they were crank and rolled up to twenty degrees. They were also very wet at high speeds and suffered from a slight weather helm. Nevertheless, the ships turned tightly and were very maneuverable. In a hard turn, their speed fell up to 35 percent. They had a transverse metacentric height of 0.59m (01.94feet). German: Dresden and German: Emden had a crew of 18 officers and 343 enlisted men. They carried a number of smaller boats, including one picket boat, one barge, one cutter, two yawls, and two dinghies.

German: Dresdens propulsion system consisted of two sets of Parsons steam turbines, designed to give 15000shp. German: Emden, instead, was equipped with two triple expansion engines rated at 13500ihp. Both ships had a top speed of 24kn. In both vessels, the engines were powered by twelve coal-fired Marine-type water-tube boilers. Both ships carried up to 860MT of coal, though their ranges were slightly different, owing to their different propulsion systems. German: Dresden could steam for 3600nmi at, while German: Emden had a range of 3760nmi at . Electrical power was supplied by three turbo generators that provided a total of 125 kilowatts at 110 volts.

Armament and armor

The ships were armed with ten SK L/40 guns in single pedestal mounts. Two were placed side by side forward on the forecastle, six were located amidships, three on either side, and two were side by side aft. The guns had a maximum elevation of 30 degrees, which allowed them to engage targets out to 12700m (41,700feet). They were supplied with 1,500 rounds of ammunition, for 150 shells per gun. The ships were also equipped with eight SK L/55 guns with 4,000 rounds of ammunition. Both ships were also equipped with a pair of torpedo tubes with five torpedoes submerged in the hull on the broadside.

The ships were protected by an armored deck that was up to 80mm thick amidships with thick sloping armor on the sides. The deck was reduced to 30mm further aft and then again to 20mm toward the stern. The conning tower had 100mm thick sides, and the guns were protected by 50 mm thick shields.

Service history

Dresden

See main article: SMS Dresden (1907).

German: Dresden spent most of her career on foreign stations. After her commissioning, she visited the United States in 1909 as part of Germany's delegation to the Hudson–Fulton Celebration. She returned to North American waters in late 1913, when she was stationed off the Mexican coast to protect German nationals during the Mexican Revolution. Following the rebels' victory the following year, German: Dresden evacuated the former dictator Victoriano Huerta to Jamaica, where the British had granted him asylum. In need of repairs, the cruiser was scheduled to return to Germany in July 1914, but the outbreak of World War I prevented this from taking place. Instead, German: Dresden operated as a commerce raider in South American waters in the Atlantic in the first months of the war before moving to the Pacific Ocean in September and thereafter joining Maximilian von Spee's East Asia Squadron.

German: Dresden participated in two major battles with the East Asia Squadron. The first, the Battle of Coronel, took place in November, and German: Dresden engaged the British cruiser . The second, the Battle of the Falkland Islands, followed in December, where British battlecruisers annihilated the German squadron; German: Dresden was the only vessel to escape. She eluded her British pursuers for several more months, until she put into Más a Tierra in March 1915. Her engines were worn out and she had almost no coal left for her boilers; the ship's captain contacted the local Chilean authorities to have his vessel interned for the duration of the conflict. There, she was trapped by British cruisers, including her old opponent Glasgow; the British violated Chilean neutrality and opened fire on the ship. The Germans scuttled German: Dresden and the majority of the crew escaped to be interned in Chile for the duration of the war. The wreck remains in the harbor and was first surveyed in 2002.

Emden

See main article: SMS Emden (1908).

Following her commissioning into the fleet, German: Emden was assigned to the East Asia Squadron. In 1913, German: [[Korvettenkapitän]] (Corvette Captain) Karl von Müller became the ship's commander. At the outbreak of war, German: Emden was the only major German warship in Qingdao, the main German naval base in Asia. Müller immediately began to operate as a commerce raider, and captured one ship, the Russian steamer Russian: [[SMS Cormoran (1909)|Ryazan]]. German: Emden was thereafter ordered to rendezvous with the rest of Spee's cruisers. She remained with the East Asia Squadron for only a few days, as Müller convinced Spee to detach German: Emden as an independent raider in the Indian Ocean.

After arriving in the Indian Ocean in September, German: Emden captured several British merchantmen along the sea lanes from India to Aden. On 22 September, the ship bombarded Madras, before resuming the hunt for merchant ships. She captured several more vessels, and then raided the port of Penang. There, German: Emden caught the Russian protected cruiser in the harbor and quickly destroyed her. As German: Emden was departing, she encountered and sank the French destroyer . German: Emden thereafter proceeded to the Cocos Islands, where Müller intended to destroy a wireless station. The Australian cruiser reacted to British wireless signals warning of the Germans' presence. After a fierce gunnery duel, Sydney caused serious damage to German: Emden and forced her to beach on North Keeling island. Most of her surviving crew, including Müller, were thereafter taken into captivity. The wreck was eventually broken up in situ in the early 1950s by a Japanese salvage company, though parts of the ship remain scattered around the area.
