List of avisos of Germany
The German navies, beginning with the Prussian Navy in the 1840s, acquired a series of avisos for use in a variety of roles, including as scouts, flagships for gunboat flotillas, and as dispatch vessels. The first such vessel,, was a packet steamer requisitioned for service during the First Schleswig War in 1848, though she returned to civilian duty after the war. In 1850, the Prussians ordered a pair of small vessels—the —from Britain; like Preussicher Adler, these were both paddle steamers. The first screw-driven aviso followed in 1856: the French-built. Another paddle steamer,, was laid down in 1858, the first vessel of the type built in a German shipyard. Many of these vessels served as yachts for the royal and later imperial family. During the Second Schleswig War, Loreley and Preussischer Adler saw action at the Battles of Jasmind and Heligoland, respectively.
At the start of the Franco-Prussian War in 1870, the Prussians purchased and requisitioned. Grille engaged French forces in the Baltic during the war, but the rest of the fleet's avisos saw little activity in the conflict., the first torpedo-armed aviso to be built for what was now the German Imperial Navy, was also the last major warship to be built abroad for the Imperial German fleet. The 1880s saw a significant aviso construction program that included the two s,, the two s, and the two s. The latter two classes were disappointments in service owing to their small size, insufficient speed, and in the case of the Meteors, excessive vibration from their engines., the last vessel of the type to be built for the Imperial fleet, was completed in 1895. The Germans thereafter built light cruisers that fulfilled the roles occupied by the avisos; the first of these, the, combined the best features of Hela with those of contemporary unprotected cruisers. Hela was, herself, sunk in September 1914 during World War I; the other vessels still in service saw little active use during the war and were all broken up afterward.
One final vessel,, was built in the mid-1930s for use as a yacht for Adolf Hitler. During World War II, she was used as a minelayer, training ship, and later as a stationary headquarters ship in Norway before being seized by Britain. She was then sold to a private owner after the war and was ultimately scrapped in 1951.

''Preussischer Adler''
Preussischer Adler was an iron-hulled paddle steamer originally built for the Prussian postal service to operate on the packet route between Prussia and Russia in the mid-1840s. At the time, the Prussian Navy was an anemic force consisting of a handful of small sailing vessels and cannon-armed yawls. The ship was requisitioned early in her career during the First Schleswig War to defend the Prussian coast from the more powerful Danish Navy that imposed a blockade on Prussia's and the other German states' ports. She took part in a short battle with the Danish brig, the first engagement involving the Prussian fleet. She returned to commercial duties after the war and served in that capacity uneventfully until 1862, when the expansion of the Prussian Eastern Railway rendered her superfluous. Purchased by the Prussian Navy, she was in the Mediterranean Sea with a pair of gunboats on the eve of the Second Schleswig War. The ships were recalled to Prussia but arrived after the outbreak of war. They joined a pair of Austrian screw frigates to attack the Danish blockade squadron in the Battle of Heligoland, though the Austrians bore the brunt of Danish fire. She served as the flagship of Prussian vessels in the Baltic Sea during the Franco-Prussian War of 1870–1871, but saw no action. Reduced to subsidiary duties in 1872, including as a training ship and fisheries protection vessel, she was ultimately decommissioned in April 1877 and sunk as a target two years later in June 1879.''Nix'' class
The two Nix-class avisos were ordered in the immediate aftermath of the First Schleswig War as part of a program intended to strengthen the Prussian fleet. Prince Adalbert of Prussia, one of the leading advocates for a larger navy, initially sought to have the ships built in Prussia, but domestic shipbuilders had little experience with steam ships, and so contracted with a British firm to build the vessels in 1850. The ships' careers in Prussian service proved to be short and uneventful, apart from repeated boiler fires aboard Nix. The Prussians were not satisfied with the ships, in part a result of Nixs fires and general unfamiliarity with operating steamships. They sold the vessels to Britain in exchange for the sail frigate in 1855; Nix and Salamander became HMS Weser and Recruit, respectively. The former saw action during the Crimean War at the Battle of Kinburn later that year, but both ships thereafter saw little use in the Royal Navy. Both were out of service by the mid-1860s, with Recruit being sold for scrap in 1869 and Weser following her to the breaker's yard in 1873.''Grille''
Grille was ordered in 1855 as part of Adalbert's fleet expansion program; she was the first steam ship to use screw propellers rather than the paddle wheels of earlier vessels. She was initially unarmed, being used as a royal yacht until the outbreak of the Second Schleswig War. She sortied on 16 April with Adalbert aboard to attack the Danish blockade squadron in the Baltic that resulted in an inconclusive encounter with the Danish ship of the line and the steam frigate. She next engaged the steam frigate on 24 April. She sortied twice more by early May, but on both occasions encountered far superior Danish forces and withdrew without attacking.Grille served as a yacht after the war, taking Crown Prince Friedrich to the opening ceremonies for the Suez Canal in 1867. During the Franco-Prussian War, she once again served in the Baltic, and she engaged a French blockade squadron on 17 July, interrupting French plans to attack Swinemünde. Grille remained in service through the early 1910s, serving in a variety of roles, including as a fleet scout, a tender, and as a training vessel. She ended her career as a tender for the cruiser as part of the training establishment for the Mürwik Naval School. Decommissioned for the last time in 1918, she was the longest-serving vessel of the Imperial Navy, having been on active service for sixty-two years. She was then sold for scrap in 1920.
''Loreley''
With Grille serving as a yacht in the 1850s, the navy decided it needed another aviso to serve as a flagship for the gunboat flotillas defending the country's Baltic coast. The designers reverted to paddle wheels and a wooden hull, as they were not convinced by the long-term utility of iron hulls or screw propulsion. The ship went to the Mediterranean in 1860 to protect Prussian nationals in Italy during the Second Italian War of Independence. She served in her intended role during the Second Schleswig War, and saw action at the Battle of Jasmund against the Danish blockade squadron in March 1864, where she was hit only once. She was decommissioned after the war and saw no further service for the rest of the decade.In poor condition by the late 1860s, Loreley was heavily rebuilt in 1869–1873, leading some historians to treat the vessel as two different ships. In 1879, the ship was sent to Constantinople, the capital of the Ottoman Empire, to serve as the station ship there, a right enjoyed by all of the European Great Powers after the Crimean War. She served there for the rest of her career. During this period, she helped to protect German interests in Egypt during the 'Urabi revolt in 1882, conducted training cruises in the Mediterranean, and sent men ashore in 1895 to protect Germans from domestic unrest in the Ottoman Empire. Worn out by 1896, she was decommissioned and sold later that year, but her ultimate fate is unknown.
''Falke''
Falke was originally built as a speculative project by her British constructors, who intended to sell the vessel to the Confederate States Navy for use as a blockade runner during the American Civil War. By the time work on the vessel was completed, however, the war was over, leaving the shipyard without a buyer. A private shipowner in the Netherlands purchased the vessel, renamed it Heinrich Heister, and left it idle in Rotterdam for the next five years. She was purchased by what was now the North German Federal Navy in August 1870, shortly after the outbreak of the Franco-Prussian War, but she was accidentally rammed by the turret ship shortly after entering service as Falke, causing serious damage that ended her wartime career. She operated with the fleet through the 1870s, but suffered repeated machinery breakdowns, thereafter serving as a tender for the Marinestation der Nordsee in the early 1880s. Later in the decade, she was used for fisheries protection before being decommissioned in 1888, struck from the naval register in 1890, and sold for scrap in 1892.''Pommerania''
Pommerania was built for the Prussian postal service as a packet steamer, though the exact nature of her design and construction is uncertain. The navy's chief designer prepared the plans for the ship and the navy subsidized construction costs, which led the naval historians Hans Hildebrand, Albert Röhr, and Hans-Otto Steinmetz to suggest that the navy wanted to have a steamship it could requisition when needed but would not have to maintain. The navy brought the ship into commission during the Franco-Prussian War but crew shortages delayed conversion until after the war. She was used for fishing surveys in 1871 and 1872, with this work providing the scientific basis for the German Fisheries Act passed in 1874. She went to the Mediterranean with the ironclad training squadron in 1876 in response to the murder of a German diplomat in Salonika. She remained in the region after the outbreak of the Russo-Turkish War of 1877–1878, staying in Constantinople with Loreley. After returning to Germany, she served as a tender to the Marinestation der Nordsee from 1881 to 1884, thereafter seeing service as a fisheries protection vessel and survey ship. Decommissioned in 1889 and struck in 1890, she was sold to a shipping company, converted into a sailing schooner, and renamed Adler. She was lost in a storm on her maiden voyage on 20 January 1894.''Zieten''
Beginning in 1869, the North German Federal Navy, under the direction of Albrecht von Stosch, began to consider the new self-propelled Whitehead torpedoes; Stosch authorized construction of a new aviso to test the weapons in 1873. Laid down at the Thames Iron Works, Zieten was the last major warship of the Imperial German fleet to be built overseas. Zieten proved to be highly influential, as experiments with the new torpedoes not only led to further construction of torpedo-armed warships, but also inspired similar vessels in the French, Italian, and Austro-Hungarian fleets. The Austro-Hungarian chief construction, Josef von Romako, based his design of the s directly on that of Zieten.Future admiral Otto von Diederichs served aboard the ship during her first year in service, which involved tests of the bow torpedo tubes that demonstrated that the bow tube, located in the hull below the waterline, was not satisfactory; Diederichs arranged for the tube to be moved to a swivel mount on the deck. Another future admiral, Alfred von Tirpitz, took command of the vessel in 1878; during training exercises in 1880, Tirpitz arranged a demonstration of the vessel's effectiveness by sinking the old paddle steamer. She went to the Mediterranean during the 'Urabi revolt in 1882 along with several other vessels. She saw limited service in the 1890s, including as a fisheries vessel until the start of World War I in 1914, after which point she was used as a guard ship. She was ultimately sold for scrap in 1921.
''Blitz'' class
The Blitz class were the first modern avisos built for the German fleet; they were the first German vessels of any type with steel hulls, and they abandoned traditional sailing rigs. They provided the basis for future developments that ultimately produced the light cruisers of the. The ships were initially armed with a gun and a torpedo tube, though their armament was improved in the early 1890s, including the addition of two more torpedo tubes.The ships had extensive careers, remaining in active service for more than thirty years. Blitz spent much of her career as a flotilla leader for torpedo boats, while Pfeil served with the training squadron and the main fleet. Pfeil was deployed to German East Africa in 1889 to suppress the Abushiri revolt, returning to Germany in 1890. Throughout the 1890s, the ships served with the fleet, conducting a yearly routine of exercises and training cruises. They served in a variety of additional roles during the 1890s and 1900s, including as tenders, fishery protection vessels, and training ships. They operated as dedicated tenders to the battle squadrons of the High Seas Fleet by the mid-1900s, filling that role through the start of World War I. Blitz took part in Operation Albion in the Baltic Sea in late 1917 and Pfeil was later used as a training ship for U-boat crews. Both ships were discarded in the early 1920s.
''Greif''
Greif was designed at a time where torpedoes had become effective weapons and spurred the development of the Jeune École, which held that cheap torpedo boats could destroy large, expensive battleships. She was intended to guard the capital ships of the fleet against torpedo boat attacks, and for this role, she carried a battery of and guns. Unlike other German avisos of the period, she carried no torpedo tubes. Greif was not a successful warship, however, and she spent much of her career laid up, out of service.Completed in 1887, Greif was not commissioned until 1889, though she remained in service with the fleet only until October 1890, when she was assigned with torpedo testing, a role she filled until 1894 when she was decommissioned. Recommissioned in May 1897, she served as a fleet scout for the next two years, thereafter being reduced to secondary roles once again, including as a training ship, before being decommissioned for the last time in September 1900. Greif was struck from the naval register in 1912, hulked in 1915 during World War I, and used as a mine storage hulk in 1917. After the war, she was sold to ship breakers in 1921 and dismantled in Hamburg.
''Wacht'' class
Following the appointment of General Leo von Caprivi as the German admiralty chief in 1883, the navy began to experiment more seriously with torpedo boats. Caprivi embraced some of the ideas of the Jeune École doctrine, mostly importantly the theory that cheap torpedo boats could be used for coastal defense instead of larger, more expensive ironclads. This strategy found favor in the Reichstag, which generally opposed expanding the naval budget. Caprivi ordered the next pair of avisos—the Wacht class—with characteristics that would allow them to operate offensively with the torpedo boat flotillas. Their high speed came at the expense of gun armament and size rather than the more balanced Blitz design. As a result, the Wachts were disappointments in service.The two ships spent most of their careers with the main fleet. Wacht went on a major cruise to the Mediterranean Sea in 1889. Jagd was the first ship to pass through the Kaiser Wilhelm Canal in 1895 before the canal officially opened. Badly worn out by mid-1901, Jagd was decommissioned in August. The following month, Wacht was accidentally rammed and sunk by the ironclad, though her entire crew was safely evacuated. Jagd was struck from the register in 1910 and used as a torpedo training platform until 1920, when she was sold for scrap.
''Meteor'' class
Unlike earlier avisos built for the fleet, which were designed to fill a variety of roles, the Meteor class was intended to protect the fleet's capital ships from torpedo boat attacks. They were armed with a battery of four quick-firing guns. Both vessels suffered from serious problems that rendered them unfit for service, namely poor seakeeping and excessive vibration of their propeller shafts. As a result, they saw little service, with Comets only periods in commission being to test what were unsuccessful attempts to correct the problems. Meteor had a somewhat more active career, serving with the fleet in 1893–1894 and then as a fishery protection ship in 1895–1896, but she, too, spent most of her existence laid up. Both vessels were decommissioned in 1896 and struck from the naval register in 1911. Meteor was then used as a barracks ship, while Comet became a storage hulk; the two ships were broken up in 1919 and 1921, respectively.''Hela''
Helas design was intended to correct many of the deficiencies in the Wacht and Meteor classes, mainly through an increase in size that would produce improved seaworthiness. She was also a knot faster, which increased her usefulness as a fleet scout. She nevertheless proved to be too weakly armed for fleet service, and the next cruising-type vessel to be built in Germany was the Gazelle class of light cruisers; they were the first vessels of that type to be built, and they incorporated the best aspects of Hela and the unprotected cruisers that had been built in the 1880s and 1890s.The ship served with the fleet from 1898 to 1902, and during this period, from mid-1900 to mid-1901, she was deployed as part of an expeditionary force sent to help suppress the Boxer Rebellion in Qing China. The naval command decided her armament was insufficient for front-line use, so she was extensively modernized between 1903 and 1910, thereafter serving as a tender until the outbreak of World War I. She was then assigned to support the patrols in the German Bight. She was present at the Battle of Helgoland Bight in August 1914 but was not directly engaged. The following month, she was torpedoed and sunk by the British submarine while steaming off Helgoland, though only two men were lost in the sinking.
