Almirante Barroso was a cruiser operated by the Imperial Brazilian Navy and later the Brazilian Navy from 1882 to 1893. Its name is a tribute to Brazilian admiral Francisco Manuel Barroso da Silva, the Baron of Amazonas. Its construction began in 1880 at the Rio de Janeiro Navy Arsenal, being launched into the sea in 1882. The ship was a demonstration of the potential of the Brazilian naval industry at the time, built with a combination of wood and steel.

Almirante Barroso had a displacement of 2,050 tons and a speed of 13 knots. Its armament included Whitworth cannons, Nordenfelt machine guns, and a Kropatshek portable weapon system. The construction of the ship was a substantial investment, totaling 1.4 billion réis.

After its incorporation into the Evolutions Squadron in 1884, Almirante Barroso participated in instructional commissions and trips around the world, reinforcing the modernization of the Imperial Brazilian Navy. However, the vessel faced a relatively tense moment during the fall of the Brazilian monarchy in 1889, when August Leopold, the Imperial Prince of Brazil, on board the ship during a circumnavigation trip, found himself involved in the political transition.

The ship then continued its circumnavigation journey which culminated in its return to Rio de Janeiro in 1890, after a 301-day voyage around the world. Almirante Barroso was shipwrecked in 1893 on a coral reef in the Red Sea. Despite rescue efforts, the ship could not be saved, resulting in its loss. Years later, divers claimed to have found its remains, but were unable to prove the origins of the shipwreck.

The ship's technical specifications were: displacement of 2,050 tons, total length of 71.25 m (233.8 ft), a length between perpendiculars of 64.05 m (210.1 ft), a width of 11.33 m (37.2 ft), a depth of 10.97 m (36.0 ft) and an average draft of 6.4 m (21 ft). The ship's engine, designed under the plans and supervision of lieutenant captain and naval engineer Manuel Alves Barbosa, had an effective power of 2,200 hp that allowed the vessel to reach a speed of 12[1] or 13[2] knots.[1] In addition to the machines, the cruiser also had sails as a means of propulsion, being rigged as a corvette with a surface area of 1,625 m2 (17,490 sq ft).[3]

The ship was equipped with two Admiralty-type boilers. In addition, it had a propeller and a chimney. The construction cost of this warship was substantial, totaling 1.4 billion réis.[1] The ship's artillery included six 70-pounder Whitworth naval guns mounted on rifled Levasseur carriages, arranged en barbette. In addition, the ship was equipped with a bow gun, four 25 mm Nordenfelt machine guns and six 11 mm machine guns of the same type. Later, the ship's portable armament was upgraded with the Kropatshek system.[1] Its crew consisted of 285 officers and enlisted men.[2] In general, Almirante Barroso was already outdated in the decade prior to its construction,[4] despite representing an evolution of the Brazilian naval industry in the construction of this type of vessel since the period before the Paraguayan War (1864–1870).[5]

Construction

Almirante Barroso was the second ship in the Brazilian Navy to bear this name. It is a tribute to admiral Francisco Manuel Barroso da Silva, the first and only Baron of Amazonas.[3] The other vessels that paid homage to the Brazilian hero were the ironclad Barroso (1865), the cruiser Almirante Barroso (C-1) (1895), the light cruiser Barroso (C-11) (1951) and the corvette Barroso (2008).[6] The iron used in its construction was produced by the São José do Ipanema Factory.[7]

The ship's keel was laid at the Rio de Janeiro Navy Arsenal on 1 March 1880. The launch event, which took place on 17 April 1882, was a celebration attended by emperor Pedro II, the Baron of Amazonas himself, state ministers, local authorities and a crowd of people. Christened with pomp, the ship carried out its armament display on 19 July 1882 and received its badge number 22. The ship, of mixed construction, incorporating wood and steel, was a demonstration of the potential and ingenuity of the Brazilian naval industry and force at the time.[1]
