Almirante Brown was a heavy cruiser in service with the Argentine Navy. The ship was named in honour of Admiral Guillermo Brown, the Father of the Argentine Navy.
Almirante Brown was built by Odero in Genoa (Italy), laid down 27 November 1927, launched on 11 August 1929, and completed 11 July 1931. Her total displacement was 6,800 tons. The ship was broadly similar to the Italian but was armed with three twin gun turrets as against four twin 8inches guns. Another important difference was the repositioning of the boilers, which gave the ship a single funnel. On trials the cruiser reached its contracted speed of 32kn. As completed the ship had a short funnel but it was subsequently raised. During the Second World War the ship finally received the catapult which had been included in the original design. The catapult and crane were carried on the centreline between the funnel and mainmast, with two Grumman floatplanes. When built six twin anti-aircraft guns were mounted at forecastle deck level but these were later replaced by twin Bofors guns.
Almirante Brown was decommissioned on 27 June 1961 and sold for breaking up in Italy in 1962.
