Gazelle-class cruiser

File:Bundesarchiv Bild 134-C0105, SMS "Geier", Kleiner Kreuzer.jpg

Through the 1870s and early 1880s, Germany built two types of cruising vessels: small, fast, but lightly armed avisos suitable for service as fleet scouts and larger, long-ranged screw corvettes capable of patrolling the German colonial empire. Beginning in the mid-1880s, General Leo von Caprivi, the Chief of the Imperial Admiralty, embarked on a construction program to modernize Germany's cruiser force. The first step in the program, the two {{sclass|Schwalbe|cruiser|0}} unprotected cruisers, provided the basis for the larger {{sclass|Bussard|cruiser|4}}. All of these vessels were comparatively slow, capable of no more than {{convert|15.5|kn|lk=in}}, which was not sufficient for scout operations with the main fleet.{{sfn|Nottelmann|pp=102–104}}{{sfn|Sondhaus|pp=166–167}}

In the early 1890s, naval officers began to consider a new type of cruiser that incorporated the speed of the avisos with the heavier armament and longer cruising radius of the unprotected cruisers. Then-Captain Alfred von Tirpitz, at the time the Chief of Staff of the Imperial Naval High Command ({{lang|de|Oberkommando der Marine}}—OKM), wrote a summary of 1894 fleet maneuvers that included what he believed to be the necessary characteristics of a new small cruiser. These included a top speed of at least {{convert|18|kn}}, armament sufficient to permit them to engage enemy fleet scouts, and an armor deck to protect the ship's propulsion machinery.{{sfn|Nottelmann|pp=104–106}}

The General Department of the Imperial Naval Office ({{lang|de|Reichsmarineamt}}—RMA) issued a call for proposals on 10 May 1895 for the next cruiser, provisionally titled "G". Records of the initial proposals have not survived, though the final design closely followed Tirpitz's specifications outlined in 1894. The caliber of the main battery had to be limited to {{cvt|10.5|cm}}, despite his preference for larger weapons, to keep displacement within reasonable limits. Maximum speed was to be {{convert|19.5|kn}}, a margin of {{convert|3|kn}} over contemporary battleship designs. The design for the first vessel, which would become {{SMS|Gazelle||2}}, was prepared in 1895–1896 by the navy's chief designer, Alfred Dietrich. As additional members of the class were ordered, a series of improvements were incorporated in their designs over the course of 1897–1900.{{sfn|Nottelmann|pp=107–108}}{{sfn|Gröner|p=99}}

By 1897, when the second member of the class would be proposed to the {{lang|de|Reichstag}} to be included in the next year's budget, developments in other vessels prompted the first of these changes. The latest {{sclass|Kaiser Friedrich III|battleship|1}}s would have a speed of {{convert|18|kn}}, necessitating an increase in speed to maintain the 3-knot speed advantage. The RMA also considered increasing the caliber of main guns in line with Tirpitz's thinking, but Dietrich stated that the requested improvements could not be incorporated while retaining a displacement of not more than {{convert|3000|t|LT|lk=on|sp=us|0}}. More problematically, the cost of the new ship would increase by around 26 percent, which the {{lang|de|Reichstag}} would not likely approve. As a result, the next vessel would largely repeat {{lang|de|Gazelle}}{{'}}s design, though new machinery developed by the Germaniawerft shipyard secured the necessary increase of speed to {{convert|21.5|kn}}.{{sfn|Nottelmann|pp=108–110}}

The design was somewhat smaller than contemporary light cruisers, but the ships were nevertheless sturdy and powerfully armed for the period.{{sfn|Lyon|p=249}} These characteristics evenly balanced the requirements for the two roles envisioned for the class.{{sfn|Campbell & Sieche|p=143}} According to the historian Eric Osborne, "[t]he light cruisers of the {{lang|de|Gazelle}}-class established a trend for future ships of this general design...[they] carried little or no armor, the chief asset being speed."{{sfn|Osborne|p=55}} Indeed, all future light cruisers built by the Imperial Navy through the {{sclass|Dresden|cruiser|4}} of 1906 generally followed the same pattern, with few fundamental changes.{{sfn|Herwig|p=28}}{{sfn|Nottelmann|p=110}}

The ships of the {{lang|de|Gazelle}} class were {{convert|104.10|to|104.40|m|ftin|abbr=on}} long at the waterline and {{convert|105|m|ftin|sp=us}} long overall. The first seven ships had a beam of {{convert|12.20|m|ftin|abbr=on}} and the last three were slightly wider, at {{convert|12.40|m|ftin|abbr=on}}. They had a draft of {{convert|4.11|to|5.38|m|ftin|abbr=on}} forward and {{convert|5.31|to|5.69|m|ftin|abbr=on}} aft. They were designed to displace {{convert|2643|to|2706|t|LT|sp=us}} at a normal loading, and at full load their displacement rose to {{convert|2963|to|3180|t|abbr=on}}. The ships' hulls were constructed with transverse and longitudinal steel frames; the outer hull wall consisted of wooden planks covered with a layer of Muntz metal to prevent fouling. The Muntz metal extended up to a meter above the waterline. The hull was divided into twelve watertight compartments and it had a double bottom that extended for 40 percent of the length of the keel. For the last three ships, their double bottom was lengthened to 46 percent of the hull.{{sfn|Gröner|pp=99–100}}

All ten ships were crank and rolled severely. They were also wet in a head sea. After their modernizations, they tended to suffer from lee helm. Nevertheless, the ships turned tightly and were very maneuverable. In a hard turn, their speed fell up to 65 percent. They had a transverse metacentric height of {{convert|0.5|to|0.63|m|abbr=on}}. The {{lang|de|Gazelle}} class required a crew of 14 officers and 243 enlisted men, though for the last three ships, the number of enlisted men rose to 256. They carried a number of boats, including one picket boat, one pinnace, two cutters, two yawls, and one dinghy.{{sfn|Gröner|p=100}}

Their propulsion system consisted of two triple-expansion engines manufactured by the dockyards that built the ships. {{lang|de|Gazelle}}{{'}}s engines were designed to give {{convert|6000|ihp|lk=in}}, for a top speed of {{convert|19.5|kn}}, while the rest of the ships' engines were rated at {{convert|8000|ihp|abbr=on}} for {{convert|21.5|kn}}. The engines were powered by eight coal-fired water-tube boilers of various manufacture, divided into two boiler rooms. The first three ships carried {{convert|500|t|LT}} of coal, which gave them a range of {{convert|3570|nmi|lk=in}} at {{convert|10|kn}}. The next four vessels carried slightly more, at {{convert|560|t|LT|abbr=on}}, which allowed them to cruise to the approximately same range, {{convert|3560|nmi|abbr=on}}, at the higher speed of {{convert|12|kn}}. The last three ships carried {{convert|700|t|LT|abbr=on}} of coal, which substantially increased their cruising radius, to {{convert|4400|nmi|abbr=on}} at 12 knots. The ships were equipped with three electricity generators that provided a total of 110 kilowatts at 110 volts.{{sfn|Gröner|pp=99–101}}

The ships were armed with ten 10.5 cm SK L/40 guns in single mounts. Two were placed side by side forward on the forecastle, six were located amidships, three on either side, and two were placed side by side aft. The guns could engage targets out to {{cvt|12200|m|yd}}. They were supplied with 1,000 rounds of ammunition, for 100 shells per gun, though the allotment for the last three ships increased to 1,500 rounds, or 150 per gun. They were also equipped with torpedo tubes. {{lang|de|Gazelle}} had three {{convert|45|cm|abbr=on|1}} tubes with eight torpedoes; one was submerged in the hull in the bow and two were mounted in deck launchers on the broadside. The rest of the class only had two 45 cm tubes with five torpedoes, and these were submerged in the ships' hulls, on the broadside.{{sfn|Gröner|p=100}}

The ships were protected by an armored deck that was {{convert|20|to|25|mm|abbr=on}} thick, with {{convert|50|mm|abbr=on}} thick sloping armor on the side. The armor consisted of two layers of steel with a single layer of Krupp steel. The {{lang|de|Gazelle}}-class cruisers were also equipped with cork cofferdams to increase buoyancy. The conning tower had {{convert|80|mm|abbr=on}} thick sides, with a 20 mm thick roof. The guns were protected by {{convert|50|mm|abbr=on}} thick shields.{{sfn|Gröner|p=99}}

The ten ships of the {{lang|de|Gazelle}} class were built between 1897 and 1904, at various German dockyards, including private firms and government shipyards.{{sfn|Gröner|pp=99–102}}

The {{lang|de|Gazelle}}-class cruisers served in various capacities after their commissioning. Most of them served with the fleet reconnaissance force, though several served on foreign stations as well. {{lang|de|Gazelle}} served abroad in 1902–1904, {{lang|de|Thetis}} in 1902–1906, {{lang|de|Niobe}} in 1906–1909, and {{lang|de|Arcona}} in 1907–1910. {{lang|de|Nymphe}} was also used as a training ship for naval cadets in addition to her fleet scout role, and {{lang|de|Undine}} served as a gunnery training ship.{{sfn|Gröner|pp=101–102}}

Due to their age, the {{lang|de|Gazelles}} had been placed in reserve by 1914, but after the outbreak of World War I in August 1914, they were mobilized for active service.{{sfn|Campbell & Sieche|p=143}} Most were initially used as coastal defense vessels in the Baltic, but {{lang|de|Frauenlob}} and {{lang|de|Ariadne}} remained in service with the fleet.{{sfn|Gröner|pp=101–102}} They both saw action at the Battle of Heligoland Bight on 28 August 1914; {{lang|de|Frauenlob}} engaged and badly damaged the British cruiser {{HMS|Arethusa|1913|6}}, while {{lang|de|Ariadne}} was sunk by several battlecruisers.{{sfn|Staff|pp=8–9, 21–24}} {{lang|de|Frauenlob}} soldiered on in the fleet reconnaissance forces until the Battle of Jutland on 31 May 1916, when she was torpedoed and sunk by {{HMS|Southampton|1912|6}} in a ferocious night battle, with the loss of almost her entire crew.{{sfn|Campbell|pp=392–393}} In the Baltic, {{lang|de|Undine}} was torpedoed and sunk by the British submarine {{HMS|E19||6}} on 7 November 1915.{{sfn|Polmar & Noot|p=45}}

The seven surviving ships were withdrawn from front-line service in 1916 and disarmed, with the exception of {{lang|de|Medusa}}, which retained six of her guns, and {{lang|de|Thetis}}, which was rearmed with nine 10.5 cm U-boat guns for use as a gunnery training ship. The remaining seven cruisers survived the war and went on to serve in the new {{lang|de|Reichsmarine}}, except for {{lang|de|Gazelle}}, which was broken up for scrap in 1920. The ships remained in service throughout the 1920s, but were all withdrawn by the early 1930s. {{lang|de|Niobe}} was sold to Yugoslavia in 1925 and renamed {{lang|sh|Dalmacija}}, while {{lang|de|Nymphe}} and {{lang|de|Thetis}} were scrapped in the early 1930s. {{lang|de|Arcona}}, {{lang|de|Medusa}}, and {{lang|de|Amazone}} were used as barracks hulks for the rest of the 1930s.{{sfn|Campbell & Sieche|p=143}}{{sfn|Gröner|pp=101–102}}

After the outbreak of World War II, {{lang|de|Medusa}} and {{lang|de|Arcona}} were converted into floating anti-aircraft batteries and defended German ports from 1940 to the end of the war, when they were scuttled by their crews on 3 May 1945. {{lang|de|Amazone}} meanwhile remained in service as a barracks ship through the end of the war.{{sfn|Gröner|pp=101–102}} {{lang|sh|Dalmacija}} was captured by the Italians after the Invasion of Yugoslavia in April 1941, renamed {{lang|it|Cattaro}}, and pressed into service with the Italian Navy. She was then captured by the Germans after the Italian surrender in September 1943, and returned to her original name, {{lang|de|Niobe}}. The ship ran aground in the Adriatic in December 1943 and was destroyed by a pair of British Motor Torpedo Boats.{{sfn|Rohwer|p=294}} {{lang|de|Niobe}}, {{lang|de|Medusa}}, and {{lang|de|Arcona}} were broken up for scrap in the late 1940s, but {{lang|de|Amazone}} lingered on as a barracks ship until 1954, when she too was sold for scrapping.{{sfn|Gröner|pp=101–102}}
