The Deodoro class were two French-designed and -built coastal defense battleships built for the Brazilian Navy in the late 1890s. Upon their completion, Scientific American called them small vessels of a type "built only for second-rate naval powers," but also noted that it was a "wonder ... so much armor and armament could be carried" on a ship of its size.[1] They served the Brazilian Navy as its only modern armored warships until the arrival of two dreadnoughts in 1910.[2]
The ships had a low freeboard and long superstructures with single-gun main turrets arranged at each end. Their secondary batteries were also mounted at each end of the superstructure, albeit in casemates in each corner. All used British Armstrong guns.[3]
In 1912, both ships were overhauled with new propulsion and armament.[2] In 1924, Brazil sold Marshal Deodoro to the Mexican Navy.[4] She served for another 14 years, primarily as a training vessel.
