SMS ("His Majesty's Ship ") was the lead ship of the seven-vessel of light cruisers, built for the German (Imperial Navy) in the early 1900s. She and her sister ships were ordered under the 1898 Naval Law that required new cruisers be built to replace obsolete vessels in the fleet. The design for the class was derived from the preceding , utilizing a larger hull that allowed for additional boilers that increased speed. was armed with a main battery of ten guns and had a top speed of .

Upon commissioning in 1904, was deployed to the East-American Cruiser Division that patrolled the Atlantic coast of North and South America. She operated in the region for nearly ten years, and in that time, she visited numerous foreign ports across both continents to protect German interests abroad. These visits included two major stops in the United States for the Jamestown Exposition in 1907 and the Hudson–Fulton Celebration in 1909 and the hundredth anniversaries of the independence of Chile and Argentina, both in 1910. She also intervened in periods of domestic unrest in various Central and South American countries, assisted merchant ships that suffered accidents, and helped to evacuate more than a thousand European civilians during the Mexican Revolution in late 1913 and early 1914.

Recalled to Germany in 1914, was decommissioned in March and overhauled, which included replacing four of her 10.5 cm guns with a pair of guns. This work was still being done when World War I broke out that year, and upon completion of her modernization in May 1915, was assigned to the naval force in the Baltic Sea. She took part in several patrols in the eastern and northern Baltic to search for Russian warships, but she saw no action. She took part in the Battle of the Gulf of Riga in August, where she engaged a Russian gunboat and bombarded Russian positions ashore. While and a pair of torpedo boats were on patrol in December 1915, one of the torpedo boats entered a Russian minefield, striking a mine. When moved to assist the stricken vessel's crew, she, too, struck a pair of mines and sank, taking most of her crew with her.

Design

The German 1898 Naval Law called for the replacement of the fleet's older cruising vessels—steam corvettes, unprotected cruisers, and avisos—with modern light cruisers. The first tranche of vessels to fulfill this requirement, the , were designed to serve both as fleet scouts and as station ships in Germany's colonial empire. They provided the basis for subsequent designs, beginning with the that was designed in 1901–1903. The principle improvements consisted of a larger hull that allowed for an additional pair of boilers and a higher top speed.

was long overall and had a beam of and a draft of forward. She displaced as designed and up to at full load. The ship had a minimal superstructure, which consisted of a small conning tower and bridge structure. Her hull had a raised forecastle and quarterdeck, along with a pronounced ram bow. She was fitted with two pole masts. She had a crew of 14 officers and 274–287 enlisted men.

Her propulsion system consisted of two triple-expansion steam engines driving a pair of screw propellers. Steam was provided by ten coal-fired Marine-type water-tube boilers, which were vented through three funnels located amidships. Her propulsion system was rated at for a top speed of . carried up to of coal, which gave her a range of at .

The ship was armed with a main battery of ten SK L/40 guns in single mounts. Two were placed side by side forward on the forecastle; six were located on the broadside, three on either side; and two were placed side by side aft. The guns could engage targets out to . They were supplied with 1,500 rounds of ammunition, for 150 shells per gun. For defense against torpedo boats, she carried ten Maxim guns in individual mounts. She was also equipped with two torpedo tubes with five torpedoes. They were submerged in the hull on the broadside.

The ship was protected by a curved armored deck that was up to thick; it sloped down at the sides to provide a measure of protection against enemy fire. The conning tower had thick sides, and the guns were protected by thick gun shields.

Service history was ordered under the contract name "L" and was laid down at the AG Weser shipyard in the ship's namesake city on 1 August 1902 and was launched on 9 July 1903. At her launching ceremony, Bremen's (mayor), Dr. Pauli, christened the ship. The ship was moved to the (Imperial Shipyard) in Wilhelmshaven for fitting-out work. She was commissioned for sea trials on 19 May 1904 under the command of (KK—Corvette Captain) Paul Schlieper; during her initial testing, she reached a maximum speed of , far in excess of her design speed and very high for warships of the period. Trials were completed on 15 July and was scheduled to be decommissioned, but the naval command instead decided to send her to replace the light cruiser on a deployment to the American Station. KK Richard Koch then took command of the ship.

Deployment to the American Station

1904–1907 After making preparations for her deployment in Kiel, she left the port on 27 August and crossed the Atlantic, stopping in Funchal on the island of Madeira en route to Rio de Janeiro, Brazil, arriving there on 25 September. There, she met the flagship of the East-American Cruiser Division, the protected cruiser . By this time, the dispute with Venezuela that had prompted the Venezuelan crisis of 1902–1903 between that country and Britain, Germany, and Italy had been settled, so she was no longer needed to enforce the settlement. Instead, was tasked with showing the flag to protect German economic interests, German nationals living overseas, and assist with German diplomatic efforts. At the time, the German division used the Danish port of Charlotte Amalie on the island of Saint Thomas in the Danish West Indies as its primary base of operations.

spent the rest of 1904 cruising with one of the other members of the division, the gunboat , through mid-April 1905. During this period, the two ships stopped in Kingston, Jamaica from early December 1904 to early January 1905, and in mid-March, she towed the British barque Malva to St. George's, Bermuda. On 15 March, the division was dissolved and was then classified as an individual station ship and Koch became the senior-most officer of the German vessels in the area. then conducted training exercises with before visiting Newport News, Virginia from 19 April to 23 May, during which time she underwent an overhaul. For the rest of 1905, cruised in Central American waters, during which time she stopped in Veracruz, Mexico, where she was visited by members of the Mexican government.

In 1906, the ship returned to Newport News for another overhaul that lasted from 23 March to 14 May. After completing the repairs, cruised the east coast of South America, steaming as far south as Bahía Blanca, Argentina. She met the training ship in Port of Spain, Trinidad, on the way back north. While in Kingston, received a distress call from the Hamburg America Line (HAPAG) steamer , which had run aground on a coral reef nearby. She steamed to the ship and took off the passengers, but attempts to pull the ship free with help from failed and she had to be abandoned. In December, (FK—Frigate Captain) Hermann Alberts relieved Koch. sailed to Newport News for another overhaul from 2 March to 14 April 1907, after which she joined the armored cruiser , which had sailed from Germany to represent the country at the Jamestown Exposition commemorating the 300th anniversary of the arrival of colonists in Chesapeake Bay on 26 April. left for Germany on 3 May, but embarked on a tour of harbors along the East Coast of the United States before rejoining in Central American waters, though the latter was transferred to German West Africa on 4 July, leaving alone on the American station. In June, steamed down the Saint Lawrence River to visit Montreal, Canada, and thereafter toured ports in Labrador. The excellent conduct of the ship's crew during the visits to Canada prompted Kaiser Wilhelm II to issue an order recognizing the men.

1908–1911

arrived in Port-au-Prince, Haiti on 16 March 1908, where civil unrest threatened German nationals in the country; the Haitian government suppressed the revolt, but carried fifty-seven Germans to Kingston. She next cruised north to visit Philadelphia, Pennsylvania from 30 May to 9 June, making her the first German warship to visit the city. From there, she proceeded to New York, staying there from 10 to 19 June. She then cruised back to South American waters, and in late August assisted the Hamburg Süd (HSDG) steamer , which had run aground in the bay off Bahía Blanca. and the Norddeutscher Lloyd (NDL) steamer took off the passengers and crew. then continued on her voyage south, stopping in Punta Arenas, Chile, on 10 November before passing through the Strait of Magellan and entered the Pacific Ocean before retracing her course back to the east coast. Later in November, FK Albert Hopman replaced Alberts as the ship's commander. She stopped in La Guaira, Venezuela, in early 1909 where now-KzS Hopman made an official visit to President Juan Vicente Gómez. She stopped in Havana, Cuba, from 29 March to 2 April, where she helped suppress a fire in the harbor, along with the NDL steamer .

The ship then steamed north for another overhaul at Newport News from 6 April to 15 May. In early August, she cruised back to Port-au-Prince, where further unrest had broken out. She visited Veracruz again in early September, where Hopman and his staff visited President Porfirio Díaz. She then steamed north to join the protected cruisers and and the light cruiser , which had traveled from Germany to represent the country at the Hudson–Fulton Celebration in New York, which marked the 300th anniversary of Henry Hudson's discovery of the Hudson River and the 100th anniversary of Robert Fulton's development of the paddle steamer. The ships' contributed a total of three hundred sailors to take part in an international parade. While there, received a new commander, FK Ernst Goette. The four cruisers remained in the port until 14 October, when got underway to visit Buenos Aires, Argentina, arriving there on 14 December. While there, the French armored cruisers and also arrived and the Argentine government held a celebration for the three ships' officers.

By early January 1910, had moved to Punta Arenas, where she received orders to sail to the coast of Chile. She arrived in Tocopilla, Chile, on 16 March, where she was instructed to return to Argentina to represent Germany for the 100th anniversary of the country's independence. While on the way, she encountered a hurricane on the night of 29 April, and in the heavy seas, she suffered an explosion in her starboard side auxiliary engine room, which severely injured one man. The ship arrived in Buenos Aires on 10 May, along with the light cruiser , which was on its way to join the East Asia Squadron. The celebrations commemorating the May Revolution ended on 30 May and continued her voyage to Asia, though remained in the port until 15 June before embarking once again for the west coast of South America. Her voyage up the western coast of the continent stopped in Callao, Peru, when once again received a change of orders on 4 September, directing her to return south to Chile to take part in celebrations marking the 100th anniversary of the start of the Chilean War of Independence. She lay in the harbor at Valparaíso for celebrations that lasted from 28 September to 3 October.
