Hamidiye was a unique ironclad warship built for the Ottoman Navy in the 1870s, the last vessel of the type completed for the Ottomans. She was a central battery ship, mounting most of her armament in a central casemate. The ship, built by the Ottoman Imperial Arsenal took nearly twenty years to complete; she was laid down in December 1874, launched in 1885, and completed in 1894. Due to her lengthy construction period, she was already obsolete by the time she was launched. Her poor handling and low quality armor contributed to a short career, spent almost entirely as a stationary training ship. She was briefly activated in 1897 during the Greco-Turkish War, but she was already in bad condition just three years after she entered service, as was the rest of the ancient Ottoman fleet. The Ottomans embarked on a reconstruction program after the incident humiliated the government, but Hamidiye was in too poor a state by 1903 to warrant rebuilding, and she was accordingly decommissioned that year, placed for sale in 1909, and sold to ship breakers in 1913.
Characteristics
In 1861, Abdülaziz became sultan of the Ottoman Empire, and thereafter began a construction program to strengthen the Ottoman Navy, which had incurred heavy losses during the Crimean War of 1853–1856. He ordered several ironclad warships from shipyards in Britain and France, though the program was limited by the Ottoman Empire's limited finances. Hamidiye was one of a handful of ironclads to be ordered from the Ottoman Imperial Arsenal; her design was based on preceding, British-built Mesudiye-class central battery ships, albeit reduced in scale to the size of the earlier Osmaniye class. In addition, a protected rudder was incorporated into the hull.[1][2] She was the last ironclad to be built for the Ottoman Navy; two Peyk-i Şeref-class ironclads were ordered from Britain after Hamidiye, but both ships were purchased by the Royal Navy before completion.[3] She was also the last central battery ship to be completed, though the German Oldenburg was begun after Hamidiye, she was completed before Hamidiye entered service.[4] Lastly, she was the final ironclad of any type to carry muzzle-loading guns.[2]
Hamidiye was 87.6 m (287 ft 5 in) long between perpendiculars and 89 m (292 ft) long overall. She had a beam of 16.9 m (55 ft 5 in) and a draft of 7.5 m (24 ft 7 in). Her hull was constructed with iron, and displaced 6,594 metric tons (6,490 long tons) normally. She had a crew of 350 officers and enlisted men as completed.[5][6] The ship was fitted with three pole masts, and the foremast carried a single searchlight. She was equipped with torpedo nets, but the wooden booms were carried aboard the ship, rather than attached to the sides of the hull, and the nets were kept ashore.[7]
The ship was powered by a single horizontal, two-cylinder compound steam engine manufactured by Maudslay, which drove one screw propeller. This engine had originally been intended for the frigate Selimiye, but had never been installed. The very lengthy construction time for the ship left the engine idle in the dockyard for some twelve years, during which time numerous components were stripped for use in other projects, so that by 1883, it had to be completely rebuilt. Steam was provided by four coal-fired box boilers manufactured by the Imperial Arsenal, which were trunked into a single funnel amidships. The engine was rated at 6,800 indicated horsepower (5,100 kW) and produced a top speed of 13 knots (24 km/h; 15 mph) on sea trials. Hamidiye carried 600 t (590 long tons; 660 short tons) of coal. A supplementary sailing rig with three masts was also fitted.[6][8][9]
Hamidiye was designed to be armed with a main battery of ten 240 mm (9.4 in) 35-caliber breechloading guns manufactured by Krupp in a central casemate, firing through gun ports. These were to be supported by four 150 mm (5.9 in) 35-cal. Krupp breechloading guns and two 57 mm (2.2 in) Hotchkiss guns, the latter for defense against torpedo boats, along with two 450 mm (17.7 in) torpedo tubes. By the time she had been completed, however, she was armed with four 228 mm (9 in) muzzleloading Armstrong guns and ten of the 150 mm Krupp guns. The Armstrong guns were placed in each corner of the casemate, which allowed them a fairly wide arc of fire and limited capability for two of the guns to fire either directly ahead or astern. Six of the 150 mm guns were carried in the casemate on the broadside, three guns per side, and the remaining four were placed on the upper deck, two in the bow and two at the stern. The anti-torpedo boat battery was strengthened with the addition of six 37 mm (1.5 in) guns. The two 450 mm torpedo tubes were retained in deck-mounted launchers.[3][10][9]
The ship was protected with wrought iron armor plate that was manufactured at the Imperial Arsenal where the ship was built. She had a complete armored belt at the waterline, which extended 2 meters (6 ft 2 in) above the waterline and 2 meters (5 ft) below. The belt was 229 millimeters (9 in) thick, and tapered down to 127 mm (5 in) at either end of the ship. The casemate battery was protected with 178 mm (7 in) iron plate. The conning tower also had 178 mm thick sides on 280 mm (11 in) of cypress backing. Hamidiye's armor proved to be poor quality, being described in Conway's All the World's Fighting Ships as "very spongy and flaky".[5][9]
