context_page_description: SMS Árpád was a pre-dreadnought battleship built by the Austro-Hungarian Navy in the early 20th century. She was launched on 11 September 1901 as the second of three Habsburg-class battleships. Along with her sister ships, she participated at the bombardment of Ancona during World War I. Due to a shortage of coal, she was soon decommissioned after the bombardment of Ancona and used as harbor defense ship for the remainder of the war. After the war, all of the Habsburg-class battleships were ceded to Great Britain as war prizes. She was scrapped in Italy in 1921.
context_section_description: Árpád was the second of three battleships of her class. Her hull was laid down on 10 June 1899 at the Stabilimento Tecnico Triestino shipyard in Trieste. Following more than two years of construction, she was launched on 11 September 1901. After final fitting-out work was finished, Árpád was fully ready for service and commissioned into the Austro-Hungarian Navy on 15 June 1903.
  Like all ships of her class, Árpád was 113.11 m (371 ft 1 in) long at the waterline and was 114.55 m (375 ft 10 in) in overall length. She had a beam of 19.8 m (65 ft 0 in) and a draft of 7.5 m (24 ft 7 in). Freeboard was approximately 5.8 m (19 ft) forward and about 5.5 m (18 ft) aft. She also displaced 8,364 metric tons (8,232 long tons). Once construction on her had finished and she was commissioned into the Navy, Árpád had a crew of 638 officers and enlisted men.
  Árpád was powered by 2-shaft, 4-cylinder vertical triple expansion engines, which were supplied with steam by 16 Belleville boilers. Árpád's power output was rated at 14,307 indicated horsepower (10,669 kW), which produced a top speed of 19.65 knots (36.39 km/h; 22.61 mph).
  The hull for the ship was constructed from longitudinal and transverse steel frames, over which the outer hull plates were riveted into place. The hull incorporated a double bottom that ran for 63% of the ship's length. A series of watertight bulkheads also extended from the keel to the gun deck. All in all, there was a total of 174 watertight compartments in the ship. Árpád had a metacentric height of between .82 m (2.7 ft) and 1.02 m (3.3 ft). Bilge keels were mounted on either side of the hull to reduce rolling and prevent her from capsizing. Árpád had a flush main deck that was planked with wood, while the upper decks were covered with linoleum or corticine.
  Árpád had three 24 cm (9.4 in) L/40 guns, two mounted in a twin turret forward and one mounted in a single turret aft of the main superstructure. The C 97-type guns were manufactured by Krupp in Germany. The main guns fired at a rate of between three and four 215 kg (474 lb) armor-piercing (AP) shells per minute. Her secondary armament consisted of twelve 15 cm (5.9 in) SK L/40 guns in casemates. These guns could fire at 4–5 shells per minute. She was built with face-hardened chrome-nickel steel. The main armored belt was 220 mm (8.7 in) in the central portion of the ship, where the ammunition magazines, machinery spaces, and other critical areas were located. The belt tapered slightly to 180 mm (7.1 in) on either end of the central section.
