context_page_description: SMS Tegetthoff was an ironclad warship of the Austro-Hungarian Navy. She was built by the Stabilimento Tecnico Triestino shipyard in Trieste, between April 1876 and October 1881. She was armed with a main battery of six 28 cm guns mounted in a central-battery. The ship had a limited career, and did not see action. In 1897, she was reduced to a guard ship in Pola, and in 1912 she was renamed Mars. She served as a training ship after 1917, and after the end of World War I, she was surrendered as a war prize to Italy, which sold her for scrapping in 1920.
context_section_description: Tegetthoff was 89.39 meters (293.3 ft) long at the waterline and 92.46 m (303.3 ft) long overall. She had a beam of 21.78 m (71.5 ft) and a draft of 7.57 m (24.8 ft) and she displaced 7,431 long tons (7,550 t). Tegetthoff was the first ship in the Austrian Navy to be built with an all-steel hull, which allowed for a considerable savings in weight. The ship's crew numbered 525 officers and men, though after her reconstruction in the mid-1890s, this number was increased to between 568 and 575. The main armored belt and the casemate for the main battery guns were protected with 356 mm (14 in) thick armor plate, and the end bulkheads of the armored citadel were 254 to 305 mm (10 to 12 in) thick. The conning tower had sides that were 127 to 178 mm (5 to 7 in) thick.
  As built, the ship was powered by a single 2-cylinder, vertical compound steam engine that was rated at 6,706 indicated horsepower (5,001 kW). This gave Tegetthoff a top speed of 13.97 knots (25.87 km/h; 16.08 mph) on trials. After her reconstruction in the early 1890s, her propulsion system was replaced with a pair of 3-cylinder triple expansion engines built by the German firm Schichau-Werke. These were rated at 8,160 ihp (6,080 kW), for a top speed of 15.32 kn (28.37 km/h; 17.63 mph) on trials. After the refit, she was equipped with eight Scotch marine boilers. She was initially fitted with a sailing rig, though this was removed during the modernization, and two heavy fighting masts were installed in its place.
