Charles Martel was a pre-dreadnought battleship of the French Navy built in the 1890s. Completed in 1897, she was a member of a group of five broadly similar battleships ordered as part of the French response to a major British naval construction program. The five ships were built to the same basic design parameters, though the individual architects were allowed to deviate from each other in other details. Like her half-sisters—, , , and —she was armed with a main battery of two guns and two guns. The ship had a top speed of . Charles Martel spent her active career in the Escadre de la Méditerranée (Mediterranean Squadron) of the French fleet, first in the active squadron, and later in the Escadre de réserve (Reserve Squadron). She regularly participated in fleet maneuvers, and in the 1901 exercises, the submarine hit her with a training torpedo. Charles Martel spent just five years in the active squadron, having been surpassed by more modern battleships during a period of rapid developments in naval technology. She spent the years 1902–1914 mostly in reserve, and the navy decommissioned the vessel in early 1914, hulking her and converting her into a barracks ship. After the outbreak of World War I in August, her guns were removed for use on the front and she briefly served as a prison ship. Charles Martel was condemned in 1919 and was sold for scrap the following year. Design In 1889, the British Royal Navy passed the Naval Defence Act that resulted in the construction of the eight s; this major expansion of naval power led the French government to pass its reply, the Statut Naval (Naval Law) of 1890. The law called for a total of twenty-four "cuirasses d'escadre" (squadron battleships) and a host of other vessels, including coastal defense battleships, cruisers, and torpedo boats. The first stage of the program was to be a group of four squadron battleships that were built to different designs but met the same basic characteristics, including armor, armament, and displacement. The naval high command issued the basic requirements on 24 December 1889; displacement would not exceed , the primary armament was to consist of and guns, the belt armor should be , and the ships should maintain a top speed of . The secondary battery was to be either or caliber, with as many guns fitted as space would allow. The basic
