ARA Almirante Brown was a central battery ironclad of the Argentine Navy built in the 1880s by Samuda Brothers in London. Almirante Brown displaced 4,200 long tons (4,300 t) and had a top speed of 14 knots (26 km/h; 16 mph). The ship was protected by a belt of nine-inch (230 mm) steel-faced armor and she carried a main battery of eight breech-loading guns. She was among the first major warships in the world to use steel armor, and remained the largest vessel in the Argentine fleet for nearly two decades. Almirante Brown had a peaceful career in the fleet during the 1880s and 1890s. By the 1920s, she was reduced to a coastal defense ship, and remained in service until the early 1930s. She was stricken from the naval register in November 1932 and sold for scrapping.
Almirante Brown was 240 feet (73 m) long between perpendiculars, and had a beam of 50 ft (15 m) and a draft of 20 ft 6 in (6.25 m). She displaced up to 4,200 long tons (4,300 t) with a combat load. Her hull was steel-built, with a wood and zinc sheathing. The hull included a double bottom and a ram bow. She was fitted with two pole masts. The ship had a crew of 520 officers and men.
Her propulsion system consisted of two compound steam engines that drove a pair of propellers. Steam for the engines was provided by eight coal-fired, cylindrical water-tube boilers. The boilers were split into four separate, watertight boiler rooms, and both of the steam engines were in individual engine rooms. The engines were rated at 5,400 indicated horsepower (4,000 kW) and produced a top speed of 14 knots (26 km/h; 16 mph). Almirante Brown had the capacity to store up to 650 metric tons (640 long tons; 720 short tons) of coal for the boilers. In addition to her steam engines, Almirante Brown was fitted with a sailing rig for auxiliary cruising. The sail plan had an area of 10,000 square feet (930 m2).
