Aldea was one of six vessels in its class to serve Chile. The class was ordered from the United Kingdom and delivered in 1928 and 1929. Like its sister shipsRiquelme and Videla, it was also equipped for duties as a minesweeper. The vessels had a displacement of 1,430 long tons (1,453 t) at full load and were armed with three 4.7 in (120 mm)/45 and one 3 in (76 mm)/40 DP gun, as well as six 21-inch (533 mm) torpedo tubes. The ships could make 35 knots (65 km/h; 40 mph), but their light build proved unsuitable for the harsh southern waters off Chile's coast.
