Iltis-class gunboat

The German (Imperial Navy) abandoned gunboat construction for more than a decade after , launched in 1887. General Leo von Caprivi, the chief of the (Imperial Admiralty) at the time, preferred a strategy of coastal defense, which meant concentrating the fleet in home waters and orienting it for defensive operations. The creation of the German colonial empire beginning in 1884 threatened Caprivi's plans, however, and necessitated the construction of vessels that could patrol Germany's fledgling empire. Caprivi began with the two s in the mid-1880s. By the early 1890s, the navy began planning to replace the older vessels of the and es, though they expected the Wolfs to remain in service until 1908. An early proposal in 1892 envisioned ordering four more s on top of the six already under construction, but the idea came to nothing. The (Naval High Command) requested a total of nine gunboats to be operational by the end of the decade. But the loss of the gunboat —one of the Wolf-class ships—necessitated an immediate replacement, which was added to the 1898 naval budget. The new ship was planned to patrol the German colonial empire; requirements included engines powerful enough for the ship to steam up the Yangtze in China, where the new gunboat was intended to be deployed. The ships would carry only a light armament, as they were not intended to engage in combat with equal counterparts; the ships would only be used to patrol the colonies. Six ships were built in three identical pairs; each subsequent pair of vessels introduced incremental improvements to the class. General characteristics The ships of the Iltis class varied slightly in dimensions. The first four ships were long overall and had a beam of , while Panther and Eber were long overall; their beam increased slightly to . The ships had a draft of forward. Iltis and Jaguar displaced as designed and at full load. Tiger and Luchs had the same design displacement, but full load increased to . The final pair of ships, Panther and Eber, increased design displacement to and full load to . Their hull consisted of transverse steel frames, over which the composite steel and timber hull planking was laid. They were sheathed in Muntz metal to protect them from marine biofouling on extended voyages abroad. The first three ships' hulls were divided into eleven watertight compartments, while the rest of the class only had ten. They all had a double bottom under the propulsion machinery spaces. The first two ships had a raised forecastle deck and a pronounced ram bow, while the latter four exchanged the ram for a straight stem. Their superstructure consisted primarily of a conning tower with an open bridge atop it, along with a smaller deck house further aft. The ships were fitted with a pair of pole masts for signaling purposes. The only armor protection carried by the ships was of steel plate on the conning tower, which was suitable only against rifle bullets and shell fragments. Steering was controlled via a single rudder, and they maneuvered well under most conditions, apart from shallow waters or at high speed. The ships handled generally well, and were considered good sea boats, but they rolled badly in a beam sea. They also suffered from significant yaw and heel in a quartering sea. Despite their small size, they were generally dry vessels. For Panther and Eber, their deadwood was extended to correct the tendency to lose way. They had a crew of 9 officers and 121 enlisted men. Each vessel carried a number of smaller boats, including one barge, one launch, one cutter, one yawl, and one dinghy. In addition, Panther and Eber each carried a second cutter, and while the Iltis-class ships operated in Chinese waters, they carried a pair of sampans as well. Machinery Iltiss propulsion system consisted of a pair of horizontal triple-expansion steam engines, each driving a single three-bladed screw propeller; the rest of the class received vertical triple-expansion engines. The engines were placed in a single engine room. Steam for the engines was supplied by four coal-fired Thornycroft boilers, with the exception of Eber, which received four navy-type boilers. All ships had their boilers installed in a single boiler room. Exhaust was vented through two funnels located amidships. The first four ships carried a pair of electricity generators that produced at 67 Volts, while Panther and Eber had three generators that produced at 67 Volts and at 110 Volts, respectively. The ships were rated to steam at a top speed of at , though all members of the class exceeded these figures in service. The ships' coal storage varied significantly, as did their engines' efficiency. Iltis and Jaguar carried a maximum of of coal, and had a cruising radius of about at a speed of . At the same speed, Tiger and Luchs were capable of only , from a maximum capacity of of coal. Panther and Eber, meanwhile, carried of coal and could sail for at that speed. Armament Iltis and Jaguar were armed with a main battery of four SK L/30 guns, with 1,124 rounds of ammunition. These weapons had a maximum range of . Two guns were placed side-by-side on the forecastle and the other pair side-by-side near the stern. The rest of the class exchanged these guns for a pair of SK L/40 guns, which had become available during the design process for the third member of the class. These guns were supplied with 482 rounds of ammunition, and could engage targets out to . These were also carried at the bow and stern, but singly. The mounts initially used for the 10.5 cm guns proved to be fragile, as demonstrated by Panthers engagements in 1902 against the Haitian gunboat and Venezuelan coastal fortifications, which led to modifications that resulted in an improved mounting. All six ships also carried six Maxim guns, which were supplied with a total of 9,000 rounds of ammunition. ==Ships==

East Asia Squadron After entering service in 1899, Iltis was deployed to the East Asia Squadron, based in Qingdao, China. Jaguar joined her there later that year. Tiger was similarly sent to East Asia in 1900. Luchs was initially intended to serve on the American Station, but she was reassigned to the East Asia Squadron before she entered service in 1900, as a result of the start of the Boxer Uprising in China. Iltis was heavily involved in the initial operations by the Eight Nation Alliance to suppress the Boxers, and then fight Qing troops supporting them. Iltis contributed men to landing parties to secure Tientsin, and in June 1900, she saw significant fighting at the Battle of the Taku Forts, leading the naval assault on the forts guarding the entrance to the Hai River. During the action, Iltis received numerous hits and suffered relatively heavy casualties, including the first German naval officer killed in action. The ship's captain, Wilhelm von Lans, was seriously wounded during the battle and received the Pour le Merite for his actions. Iltis was similarly decorated. Jaguar, meanwhile, was used to protect Germans in various port cities during the conflict. Tiger did not participate in any fighting during the Boxer Uprising, and instead patrolled the Yellow Sea. After Luchs arrived, some of her men and guns were transferred to , which was purchased to serve as a river gunboat during the fighting in China. In the years after the conflict, the members of the class patrolled the Far East, normally without incident. During the Russo-Japanese War of 1904–1905, Jaguar cruised in Korean waters to ensure that the fighting there did not affect German interests. Tiger was used to evacuate Germans from Incheon, Korea in the early stages of the war. Jaguar next participated in the suppression of rebellions against German rule in the Caroline Islands and German Samoa in 1908 and 1909, respectively. Iltis saw no further significant action for the remainder of her time in East Asian waters, though her crew remained on alert during the Xinhai Revolution against the Qing government in 1911 and 1912. During the revolution, Jaguar, Tiger, and Luchs patrolled several Chinese ports to be available in the event the fighting began to affect Germans in China. After the start of World War I in July 1914, Iltis was disarmed; some of her weapons and crew were sent to convert a captured Russian merchant vessel into the auxiliary cruiser , while the rest were used to strengthen the defenses of Qingdao. Tiger and Luchs were similarly disarmed; their guns and part of their crew were used to equip the steamer . The rest of the men were used to strengthen the German land defenses. Jaguar was the only vessel of the four Iltis-class ships operating in China that was kept in service after the outbreak of World War I in July 1914. She saw significant action during the Siege of Qingdao, engaging in artillery duels with Japanese field guns. As the German position in Qingdao worsened, Iltis and Luchs were scuttled on the night of 28–29 September to prevent their capture. Tiger was subsequently scuttled on 29 October. With the Germans set to surrender on 8 November, Jaguar was scuttled on the night of 6–7 November. Panther and Eber Panther spent most of her career abroad, where she was involved in a number of international disputes. She was initially sent to the American Station after entering service in 1902, and she was soon sent to Haiti to intervene in the Markomannia incident, where she sank the Haitian gunboat Crête-à-Pierrot. Panther was next involved in the Venezuelan crisis of 1902–1903, during which she participated in the bombardment of Fort San Carlos. Panther returned to Haiti in 1904 to pressure the Haitian government to pay a settlement after the murder of a German diplomat in the country. In 1905 and 1906, the ship toured South America, steaming as far south as Paraguay. She was transferred to German West Africa in mid-1907. The ship patrolled Germany's West African colonies for the next four years, largely uneventfully. Recalled to Germany for repairs in 1911, she stopped in Agadir, Morocco, at the request of the Foreign Office, touching off the Agadir Crisis, the most significant incident that involved Panther. The resulting international uproar created a war scare that significantly worsened Anglo-German relations. After repairs in Germany, Panther returned to Africa for another tour from 1912 to 1914, arriving back in Germany weeks before the start of World War I. She was used as a patrol vessel in the western Baltic Sea during the war, but she saw no action. After the war, she was retained by the new (Navy of the Realm) for use as a survey ship. Decommissioned in 1926, she was eventually sold to ship breakers in 1931 and dismantled. For her part, Eber saw very little activity. Completed in 1903, she spent the next seven years in reserve. She was activated for her first overseas deployment in 1910, to be sent to patrol the colonies in German West Africa alongside Panther. The next four years passed largely uneventfully for Eber, though in 1911, she participated in the Agadir Crisis in Morocco. After the start of World War I in July 1914, Eber left Africa to find a German ocean liner suitable for use as an auxiliary cruiser; she met in late August, and she transferred both of her 10.5 cm guns to Cap Trafalgar, along with most of her crew. Eber thereafter sailed for then-neutral Brazil, where she remained until the Brazilian government entered the war on the side of the Triple Entente in October 1917. To prevent her capture, the ship's remaining crew scuttled the ship on 26 October. == Notes ==
