The Lütf-ü Celil class was a pair of ironclad warships built for the Ottoman Navy by a French shipyard in the late 1860s.

Originally ordered by the Eyalet of Egypt but confiscated by the Ottoman Empire while under construction, the class comprised the vessels Lütf-ü Celil and Hifz-ur Rahman.

In the early 1860s, the Eyalet of Egypt, a province of the Ottoman Empire, ordered several ironclad warships for its fleet as part of a rearmament program to again challenge the power of the central government—the last having been the Second Egyptian–Ottoman War twenty years earlier.

After lengthy negotiations, the crisis was resolved when the Egyptian ironclads, including Lütf-ü Celil and Hifz-ur Rahman, were transferred to the central government on 29 August 1868, among other concessions made by Egypt.

Above the main belt, a strake of armor 76 mm (3 in) thick protected the turret bases, magazines, and machinery spaces.

At the start of the war, Lütf-ü Celil and Hifz-ur Rahman were assigned to the Danube Squadron,[7] where they were tasked with preventing Russian forces from crossing the river.

[9][10] Hifz-ur Rahman later assisted in the defense of Sulina at the mouth of the Danube, and engaged Russian minelayers in an action on 9 November 1877 where she was lightly damaged.

She was refitted at the Imperial Arsenal in 1891–1894, but was nevertheless in poor condition by the outbreak of the Greco-Turkish War in February 1897, like the rest of the ancient Ottoman ironclad fleet.
