The corbeta ARA Uruguay, built in England, is the largest ship afloat of its age in the Armada de la República Argentina, with more than 140 years passed since its commissioning in September 1874. The last of the legendary squadron of President Sarmiento, the Uruguay took part in revolutions, ransoms, expeditions, rescues, and was even floating headquarters of the Navy School. During its operational history 1874–1926 the Uruguay has served as a gunboat, school ship, expedition support ship, Antarctic rescue ship, fisheries base supply ship, and hydrographic survey vessel, and is now a museum ship in Buenos Aires. This ship may be the oldest in South America having been built in 1874 at Laird Bros. shipyard of Birkenhead, England, at a cost of £32,000. This ship is rigged to a barque sailplan. The ship's steel hull is sheathed in teak.
The ship's namesake is an earlier Argentine Navy schooner, a seven-gun combatant in the Battle of Juncal, 1827.
