Armament

SMS Greif was an aviso built for the German Kaiserliche Marine (Imperial Navy) in the mid-1880s, the only ship of her class. Designed at a time where torpedoes had become effective weapons and spurred the development of the Jeune École, Greif was intended to guard the capital ships of the fleet against torpedo boat attacks. For this role, she carried a battery of 10.5 cm (4.1 in) and 3.7 cm (1.5 in) guns, unlike other German avisos of the period, which also carried 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.

General characteristics

By the 1880s, the development of torpedoes and torpedo boats had produced a weapons system that could effectively challenge powerful ironclad warships. This led to the development in France of the Jeune École doctrine that emphasized the use of cheap torpedo boats and cruisers instead of expensive ironclads. As other navies, including Germany's, began to adopt the strategy, German planners saw the need for small warships capable of defending the fleet against attacking torpedo boats. The naval command called for a top speed of 19 knots (35 km/h; 22 mph), which would allow the vessel to also operate as a scout for the fleet. To keep weight limited, the armament was to consist of a pair of 10.5 cm (4.1 in) guns.[1][2] The ship proved to be a disappointment in service and she spent little time as a front-line combat unit.[3]

Greif was 99.5 meters (326 ft) long at the waterline and 102.6 m (337 ft) long overall. She had a beam of 9.75 m (32 ft) and a draft of 4.22 m (13.8 ft) forward and 4.34 m (14.2 ft) aft. The ship was designed to displace 2,050 metric tons (2,020 long tons; 2,260 short tons), and at full loading, she displaced 2,266 t (2,230 long tons; 2,498 short tons). Her hull was constructed with transverse steel frames and it contained twelve watertight compartments.[4] Unlike the other avisos and cruiser-type vessels built for the German fleet at the time, Greif carried no armor protection.[5]

Greif was a mediocre sea boat and was moderately handy. She pitched slightly but rolled significantly more. Her transverse metacentric height was 0.48 m (1 ft 7 in). The ship had a crew of seven officers and 163 enlisted men, though the latter later increased to 178. Greif carried several smaller boats, including one picket boat, two cutters, one yawl, and one dinghy.[4]

Machinery

Greif's propulsion system consisted of two horizontal 2-cylinder double expansion engines built by AG Germania, which drove a pair of four-bladed screw propellers that were 4 m (13 ft) wide in diameter. Steam for the engines was provided by six cylindrical, double-ended, coal-fired fire-tube boilers split in three boiler rooms. Each boiler room was ducted into its own funnel. In 1906, she was reequipped with eight new cylindrical boilers in two boiler rooms, which slightly improved her performance. She was equipped with a pair of generators for electrical power; they had a combined output of 20 kilowatts (27 hp) at 67 volts. Steering was controlled with a single rudder.[4]

The ship's propulsion system was rated at 5,400 metric horsepower (5,300 ihp) for a top speed of 18 knots (33 km/h; 21 mph). On trials, Greif reached 5,431 metric horsepower (5,357 ihp) and 18.2 knots (33.7 km/h; 20.9 mph). With the new boilers, her engines could reach 5,795 metric horsepower (5,716 ihp) and 19.1 knots (35.4 km/h; 22.0 mph) on speed trials. She could carry up to 350 t (340 long tons; 390 short tons) of coal, which provided a range of approximately 2,180 nautical miles (4,040 km; 2,510 mi) at a cruising speed of 12 knots (22 km/h; 14 mph). After her refit, she could carry 436 t (429 long tons; 481 short tons) of coal, which increased her range to 3,960 nmi (7,330 km; 4,560 mi) at 10 knots (19 km/h; 12 mph).[4]

Armament

Unlike the other avisos built by the German navy, which carried torpedo tubes as their primary armament, Greif was armed only with guns.[6] As built, the ship was armed with a main battery of two 10.5 cm (4.1 in) K L/35 guns placed in individual pivot mounts. She carried a secondary battery of ten 3.7 cm (1.5 in) Hotchkiss revolver cannon, also in individual pivot mounts. In 1906, the ship was rearmed with eight 8.8 cm (3.5 in) SK L/35 guns in single mounts and six revolver cannon. Later in her career, two of the 8.8 cm guns and two revolver cannon were removed.[4][7]
