SMS Loreley was an aviso of the Prussian Navy built in the late 1850s. Built as a paddle steamer, since the Prussian naval command was not convinced of the reliability of screw propellers, she was the first Prussian warship to be fitted with a domestically-produced marine steam engine. The ship carried a light armament of two 12-pound guns and had a top speed of 10.5 knots (19.4 km/h; 12.1 mph). Loreley was intended to serve as the flagship of the gunboat flotillas that formed the bulk of the Prussian fleet in the 1850s.
After entering service, the ship was sent to the Italian Peninsula in 1861 to protect Prussians and other German nationals during the Second Italian War of Independence, part of the unification of Italy. She thereafter went to Greece, the Ottoman Empire, and then to Romania before being recalled to Prussia in 1862. She served in her intended role during the Second Schleswig War, serving as the command ship for five flotillas of gunboats based in the Baltic Sea. She saw action against the Danish Navy during the war at the Battle of Jasmund, where she received a single hit that killed one man. After the war, she was decommissioned and saw little activity for the rest of the decade, by which time she was in poor condition.
Loreley was extensively rebuilt between 1869 and 1873, thereafter serving in the North Sea until 1879, when she was sent to the Ottoman Empire to serve as Germany's station ship in Constantinople. She remained there for nearly two decades to protect German interests during periods of unrest in the country. Worn out by 1896, she was struck from the naval register in August and sold in September. Her ultimate fate is unknown.
General characteristics
Following the sale of the two Nix-class avisos in 1855, the Prussian Navy had no smaller steam-driven warships; the aviso Grille, built the following year, was initially intended to serve as a royal yacht and carried no armament. The navy decided it needed a vessel that could serve as a flagship and scout for the small gunboats that formed the bulk of Prussia's small fleet. The Technical Department of the Admiralty drew up plans in 1857 for a paddle steamer that could serve in that role. At the time, naval designers had not settled on the use of screw propellers on warships, and the Prussian designers still had reservations about adopting the new technology. They also eschewed iron for the hull in favor of traditional wood planking.[1]
Loreley was 43.34 m (142 ft 2 in) long at the waterline and 47.08 m (154 ft 6 in) long overall. She had a beam of 6.6 m (21 ft 8 in) and a draft of 2.5 m (8 ft 2 in) forward and 3.02 m (9.9 ft) aft. As designed, she displaced 430 t (420 long tons) and at full load, her displacement increased to 470 t (460 long tons). Her hull was constructed with transverse wooden frames and was carvel-built; to protect from biofouling, the wooden hull planks were sheathed in copper. The hull was divided into seven watertight compartments. Her freeboard amounted to 4.9 m (16 ft 1 in).[2]
Loreley was thoroughly rebuilt between 1869 and 1873;[3] the reconstruction was so extensive, she is sometimes considered a different vessel.[4] Her original wooden hull was rebuilt with iron frames, though she retained the wooden outer planking, still sheathed in copper. Displacement fell slightly, to 395 t (389 long tons) as designed and 450 t (440 long tons) at full load. She was also shortened slightly, with a waterline length of 42.84 m (140 ft 7 in) and an overall length of 46.6 m (152 ft 11 in). Beam remained the same, but her draft increased slightly to 2.51 m (8 ft 3 in) forward and 3.05 m (10 ft) aft.[2]
Steering was controlled with a single rudder; Loreley was a mediocre sea boat and she was difficult to turn. She lost little speed in a head sea, though a beam sea caused considerable loss of speed. The ship had a crew of four officers and sixty-one enlisted men, though the latter figure was later reduced to fifty-three after the reconstruction. She carried two small boats of unrecorded type.[5]
Machinery
Loreley was propelled by a single oscillating, 2-cylinder marine steam engine manufactured by the machine shop operated by the Seehandlungsgesellschaft, the royal merchant shipping organization. This made her the first Prussian warship to be fitted with a domestically-produced engine, as all previous vessels, including those built in Prussia, used British propulsion systems. The engine drove a pair of paddle wheels, one on either side of the ship, that were 5.36 m (17 ft 7 in) in diameter and were fitted with twenty-four paddles per wheel. Steam for the engine was provided by a single coal-fired trunk boiler that was ducted into a single funnel just aft of the wheels. The boiler was built by AG Vulcan, Stettin. Her propulsion system was rated to produce 350 metric horsepower (345 ihp), for a top speed of 10.5 knots (19.4 km/h; 12.1 mph); steaming endurance figures have not survived for her original configuration. To supplement the steam engine, she was fitted as a gaff-rigged schooner, though they contributed little to her performance. Her sailing rig had a total area of 310 m2 (3,300 sq ft), though this was later reduced to 200 m2 (2,200 sq ft).[2][6]
The ship initially retained her original propulsion system during her reconstruction, but in 1879, she received new boilers that were built by the Kaiserliche Werft (Imperial Shipyard) in Wilhelmshaven. As reconstructed, her top speed fell to 9.1 knots (16.9 km/h; 10.5 mph). She carried 34 t (33 long tons) of coal, which provided a cruising radius of 450 nautical miles (830 km; 520 mi) at a speed of 9 knots.[2]
Armament
Loreley carried an initial armament of two long-barreled 12-pounder guns in individual carriages. These were supplied with a total of 240 shells. After emerging from her refit in 1873, she carried a single 12.5 cm (4.9 in) 23-caliber (cal.) breechloading hoop gun that was supplied with 142 shells. It had a range of 5,200 m (17,100 ft). In addition, she received a pair of 8 cm (3.1 in) 23-cal. breechloading guns with a total of 190 shells.[5]
