 An earlier vessel, also named Charles Martel, was laid down in 1884 and cancelled under the tenure of Admiral Théophile Aube. The vessel, along with a sister ship named Brennus, was a modified version of the Marceau-class ironclad battleships. After Aube's retirement, the plans for the ships were entirely redesigned, though the later pair of ships are sometimes conflated with the earlier, cancelled designs. This may be due to the fact that both of the ships named Brennus were built in the same shipyard, and material assembled for the first vessel was used in the construction of the second. The two pairs of ships were, nevertheless, distinct vessels.
