"Mesudiye" was poorly maintained for most of her career, including a twenty-year long period between the Russo-Turkish War in 1877–1878 and the Greco-Turkish War of 1897. As a result, she was in very poor condition by the late 1890s, which prompted a major reconstruction of her into a pre-dreadnought design type vessel in Genoa. The ship's armament was overhauled, though the gun turrets that were to have mounted guns never received the weapons. A new propulsion system was also installed, which significantly improved performance.
