Brazilian cruiser Almirante Tamandaré (1890)

Almirante Tamandaré was a protected cruiser operated by the Brazilian Navy from 1897 to 1915. The construction of the cruiser was the result of Brazil's effort to develop a large steel ship, but the country had no experience with this type of ship, and the project resulted in an unreliable vessel.

The ship measured 95.92 meters in maximum length, 14.43 meters in beam, 7.06 meters in depth, 6.02 meters in maximum draft, and displaced 4,537 tons, which made it the largest warship built in Brazil to this day. The main battery consisted of ten 152 mm cannons. Propulsion consisted of masts and steam engines. After construction, in 1890, it remained anchored in Rio de Janeiro due to navigability problems. Even before being commissioned, it was taken over by rebels during the Navy Revolt (1893–1894), and used against the federal government.

Navigability problems prevented the ship from carrying out commissions, and it only carried out two or three in its entire career. The likely first trip would have been to Santa Catarina, still under rebel control. The second was in 1908, when it traveled to Bahia. On this trip, the crew was unable to control the vessel, leaving it adrift and subsequently running aground near Morro de São Paulo. It was only after being rescued by cruisers that the vessel was able to return to Rio de Janeiro. After this trip, it was permanently anchored in the Port of Rio de Janeiro, serving as a naval school for midshipmen and cabin boys until 1914. The navy decommissioned it on 27 December 1915, and it was sent for dismantling in 1920.
