| - The Rivadavia class was a two-ship group of battleships designed by the American Fore River Shipbuilding Company for the Argentine Navy (Armada de la República Argentina). Named Rivadavia and Moreno after important figures in Argentine history, they were Argentina's counter to Brazil's two Minas Geraes-class battleships. In 1904, Brazil scrapped a previous naval building program in favor of an order that included three warships of the new 'dreadnought' type, despite signs that such an action would spark a South American naval arms race. To counter this acquisition by a major rival, Argentina began seeking bids for at least two dreadnoughts in 1908. Over the next two years, multiple shipbuilders from five countries vied for the contracts, complemented by efforts from their respective governments. Argentina was able to play this hyper-competitive environment to its own advantage by rejecting all of the initial proposals and calling for new ones that required the best aspects of each. They then repeated this process, despite complaints from shipbuilders that their trade secrets were being given away. The contracts were awarded to the lowest bidder, Fore River, in early 1910. This move shocked the European bidders, but could largely be explained by the American steel trust's ability to produce steel at a much lower cost than any other country. During their construction, the Argentine battleships were frequently subject of rumors involving their sale to a foreign country, especially after the beginning of the First World War. Under diplomatic pressure not to sell, Argentina kept the two ships. Throughout their careers, Rivadavia and Moreno were based in Puerto Belgrano and served principally as training ships and diplomatic envoys. They were modernized in the United States in 1924 and 1925 and were inactive for much of the Second World War due to Argentina's neutrality. Struck from the navy lists on 1 February 1957, Rivadavia was scrapped in Italy beginning in 1959. Moreno was struck on 1 October 1956 and was towed to Japan in 1957 for scrapping in what was then the world's longest tow (96 days).
