The New Orleans class of protected cruisers of the United States Navy consisted of two ships which were building for the Brazilian Navy at Elswick, near Newcastle Upon Tyne, England, by Armstrong Whitworth. The Brazilian Navy had ordered four Elswick cruisers, but had already sold the first ship during construction to Chile as Ministro Zenteno. One ship was delivered to Brazil, named Almirante Barroso. The third ship was fitting out as Amazonas, and the fourth was on order as Almirante Abreu.
Yashima was a Fuji-class pre-dreadnought battleship built for the Imperial Japanese Navy (IJN) in the 1890s. As Japan lacked the industrial capacity to construct such vessels, the ship was designed and built in the United Kingdom. She participated in the early stages of the Russo-Japanese War of 1904–1905, including the Battle of Port Arthur on the second day of the war. Yashima was involved in subsequent operations until she struck two mines off Port Arthur in May 1904. The ship did not sink immediately, but capsized while under tow later that day. The Japanese were able to keep her loss a secret from the Russians for over a year.
Shikishima (敷島) was the lead ship of her class of two pre-dreadnought battleships built for the Imperial Japanese Navy by British shipyards in the late 1890s. During the Russo-Japanese War of 1904–1905, the ship fought in the Battles of Port Arthur, the Yellow Sea and Tsushima and was lightly damaged in the latter action, although shells prematurely exploded in her main guns in the latter two engagements. Shikishima remained in home waters during World War I. She was reclassified as a coastal defence ship in 1921 and served as a training ship for the rest of her career. The ship was disarmed and hulked in 1923 and finally broken up for scrap in 1948.
The Eclipse-class cruisers were a class of nine second-class protected cruisers constructed for the Royal Navy in the mid-1890s.
The Swiftsure class was a group of two British pre-dreadnought battleships. Originally ordered by Chile as the Constitución class during a period of high tension with Argentina, they were intended to defeat a pair of armoured cruisers ordered by the latter country and were optimized for this role. This meant that they were smaller and more lightly armed than most battleships of the time. They were purchased by the United Kingdom in 1903 prior to their completion to prevent their purchase by the Russian Empire as tensions were rising between them and the Japanese Empire, a British ally. Completed the following year, Swiftsure and Triumph had roughly similar careers for the first decade of their service careers. They were initially assigned to the Home Fleet and Channel Fleets before being transferred to the Mediterranean Fleet in 1909. Both ships rejoined the Home Fleet in 1912 and were transferred abroad in 1913, Swiftsure to the East Indies Station as its flagship, and Triumph to the China Station.
The Highflyer-class cruisers were a group of three second-class protected cruisers built for the Royal Navy in the late 1890s.
The Blake class was a pair of first-class protected cruisers, the first of their rank in the Royal Navy, designed in the late 1880s and built around 1890.
HMS Adventure was the name ship of her class of two scout cruisers built for the Royal Navy during the first decade of the 20th century. For two years after being completed in 1905, the ship was in reserve. She was commissioned in mid-1907 as a flotilla leader in the Home Fleet. When the First World War began in August 1914, she was assigned to patrol the English Channel. In mid-1915 Adventure was transferred to Irish waters to serve as the flagship there. In early 1918, the ship escorted convoys to Gibraltar before being transferred to the Mediterranean at the end of the war. She returned home in mid-1919 and was paid off. Adventure was sold for scrap in early 1920.
HMS Attentive was one of two Adventure-class scout cruisers built for the Royal Navy during the first decade of the 20th century. Completed in 1905 the ship was placed in reserve until she was commissioned in 1907 as part of the Home Fleet. She then spent the next seven years moving on and off of active service in British waters. The ship sank one destroyer and damaged two others in collisions. Attentive was assigned to coastal defence duties when the First World War began in 1914, and spent most of the war assigned to the Dover Patrol. She played a minor role in the Zeebrugge Raid in early 1918 and was then assigned to escort convoys to Gibraltar. The ship was sent to the White Sea later in the year to support the unsuccessful North Russia intervention in the Russian Civil War. Attentive paid off at the end of 1918 and was sold for scrap in 1920.
USS Isla de Cuba was a Isla de Luzón-class protected cruiser of the United States Navy captured from the Spanish Navy during the Spanish–American War. Originally named Isla de Cuba for the Spanish colony of Cuba, the ship was ordered from the British shipbuilding company Sir W.G. Armstrong Mitchell & Company in January 1886 and laid down on 25 February 1886. The ship was launched on 11 December 1886 and completed in 1887. The vessel fought in the Rif War before being assigned to Spain's fleet in the Philippines. When the Spanish fleet in the Philippines was attacked by the United States Navy during the Battle of Manila Bay, Isla de Cuba was scuttled to prevent capture. However, the Americans raised the ship and commissioned her into the United States Navy in 1900 and assigned to the Asiatic Station, keeping the same name. In US service, the ship, rerated as a gunboat, was used to suppress the Philippine Revolution. The vessel was taken out of American service in 1904, becoming a school ship. In 1912, the US sold the ship to Venezuela which renamed her Mariscal Sucre. The ship was scrapped in 1940.
There have been at least three vessels that have served with the Brazilian Navy named Almirante Barroso, after Francisco Manuel Barroso, Baron of Amazonas:
Almirante Latorre, named after Juan José Latorre, was a super-dreadnought battleship built for the Chilean Navy. It was the first of a planned two-ship class that would respond to earlier warship purchases by other South American countries. Construction began at Elswick, Newcastle upon Tyne soon after the ship was ordered in November 1911, and was approaching completion when it was bought by the United Kingdom's Royal Navy for use in the First World War. Commissioned in September 1915, it served in the Grand Fleet as HMS Canada for the duration of the war and saw action during the Battle of Jutland.
The Almirante Latorre class consisted of two super-dreadnought battleships designed by the British company Armstrong Whitworth for the Chilean Navy. They were intended to be Chile's entries to the South American dreadnought race, but both were purchased by the Royal Navy prior to completion for use in the First World War. Only one, Almirante Latorre (HMS Canada), was finished as a battleship; Almirante Cochrane (HMS Eagle), was converted to an aircraft carrier. Under their Chilean names, they honored Admirals (Almirantes) Juan José Latorre and Thomas Cochrane; they took their British names from what was then a dominion of Canada and a traditional ship name in the Royal Navy.
A naval arms race among Argentina, Brazil, and Chile—the wealthiest and most powerful countries in South America—began in the early twentieth century when the Brazilian government ordered three dreadnoughts, formidable battleships whose capabilities far outstripped older vessels in the world's navies.
O'Higgins was a Chilean armoured cruiser. O'Higgins was built by the British shipbuilder Armstrong to the design of Philip Watts, and served with the Chilean Navy between 1898 and 1933.
Esmeralda was developed as a custom design by naval architect Philip Watts for the Chilean Navy during the Argentine–Chilean naval arms race.
In the late nineteenth and early twentieth centuries, the South American nations of Argentina and Chile engaged in an expensive naval arms race to ensure the other would not gain supremacy in the Southern Cone.
ARA Buenos Aires was a protected cruiser of the Argentine Navy. It was built by the British shipyard of Armstrong Mitchell and Co, being launched in 1895 and completing in 1896. Buenos Aires continued in use until 1932.
The Almirante Grau class was a class of two scout cruisers built for the Peruvian Navy between 1905 and 1907. Both ships remained in service until 1958.
The Chilean cruiser Esmeralda was the first protected cruiser, a ship type named for the arched armored deck that protected vital areas like propulsion machinery and ammunition magazines.
