Meteor-class aviso

The Imperial Navy began building small avisos in the 1880s to serve in the main fleet in German waters. These vessels were intended to support the battle line, as scouts for the fleet, as flotilla leaders for the fleet's torpedo boats, and as a screen against enemy torpedo boats. Unlike the contemporary German unprotected cruisers, their designs emphasized offensive capability and high speed rather than a long cruising radius. In 1888, the German naval command decided that future avisos should be focused solely on defense against hostile torpedo boats. Compared to the earlier Wacht-class avisos, the Meteor design was slightly smaller and displaced around 25 percent less than the earlier vessels. The primary alterations included a more powerful propulsion system, a new gun armament of quick-firing guns, and slightly thicker armor plating.[1][2]

Meteor and Comet proved to be failures in service. They suffered from severe vibration and their small size rendered them poor sea boats; these defects significantly curtailed their careers, and they spent most of their existence in reserve.[2][3] The Meteor class was the second to last aviso design produced by the Imperial Navy, followed only by Hela; by the 1890s, German naval designers had taken the best characteristics of the avisos and the contemporary unprotected cruisers and combined them in the Gazelle class of light cruisers, the first vessels of that type of warship.[1]

General characteristics and machinery

Meteor during her short active career

Meteor and Comet were 79.86 meters (262 ft 0 in) long at the waterline and 79.86 m (262 ft 0 in) long overall. They had a beam of 9.56 m (31 ft 4 in) and a maximum draft of 3.68 m (12 ft 1 in) forward. Meteor displaced 961 metric tons (946 long tons) as designed and up to 1,078 t (1,061 long tons) at full combat load, while Comet was slightly heavier, at 992 t (976 long tons) and 1,117 t (1,099 long tons), respectively. Their hulls were constructed from transverse steel frames. Meteor was initially fitted with a single pole mainmast, while Comet had the pole mainmast along with a smaller mast further aft for wireless telegraphy. In 1901–1902, Meteor was fitted with the second mast as well.[4]

The Meteor-class ships had a crew of 7 officers and 108 enlisted men. The ships carried several smaller boats, including one yawl, one dinghy, and one cutter. They were poor sea boats; they were very unstable in anything but calm weather. They also vibrated excessively due to severe cavitation, particularly at high speeds. Both ships were, however, very maneuverable vessels. Their metacentric height was .41 m (1 ft 4 in).[4][5]

Their propulsion system consisted of two vertical 3-cylinder triple expansion engines that drove a pair of 2.8 m (9 ft 2 in) wide, three-bladed screw propellers. Steam for the engines was provided by four coal-fired locomotive boilers that were trunked into two funnels on the centerline. The ships were equipped with a pair of electric generators with a combined output of 20 to 24 kilowatts (27 to 32 hp) at 67 volts. Steering was controlled by a single rudder.[4]

The ships' propulsion system varied slightly in performance. Meteor's engines were rated at 4,500 metric horsepower (4,400 ihp) for a top speed of 19 knots (35 km/h; 22 mph), though she exceeded both figures on sea trials, reaching a speed of 20 knots (37 km/h; 23 mph). Comet's engines were rated for 5,000 metric horsepower (4,900 ihp) and 19.5 kn (36.1 km/h; 22.4 mph), which she did not exceed on her trials. Both ships had a range of approximately 960 nautical miles (1,780 km; 1,100 mi) at 9 kn (17 km/h; 10 mph).[4]

Comet in port, date unknown

After Meteor entered service, the problems with her design became apparent; attempts to remedy the defects and sea trials to determine the efforts' effectiveness occupied much of the ship's first two years in service. This period also saw the ship take part in training exercises with the rest of the German fleet. By 1893, Comet had also entered service, and she also underwent ultimately ineffective modifications following her initial trials. Meteor was employed as a fisheries protection vessel in 1895–1896, though she proved unsuited to the task, owing to her small size, which limited the amount of coal she could store and thus the amount of time she could remain on patrol in Germany's coastal waters. As a result, she was withdrawn from that service in late 1896.[6]

Comet never saw an extended period of active service; her only periods in commission were to conduct trials after alterations were made to the ship. She, too, was laid up in 1896; both ships were reclassified as light cruisers in 1899 and then reduced to harbor guard ships in 1904. Both were struck from the naval register in 1911, with Meteor becoming a barracks ship in Kiel and Comet being converted into a storage hulk for naval mines. Meteor and Comet were sold for scrapping in 1919 and 1921, respectively.[2][3][4]
