Project history

In 1927 Chilean Government has concluded with Thornycroft the contract on building of 6 destroyers in cost on 230.000£ for each. The design was developed on the basis of constructed by the same builder British destroyer Amazon, but differed by decreased dimensions, machinery capacity and absence of gun No4. Instead Serrano, Orella and Hyatt were equipped for minelaying, and Aldea, Requelme and Videla for minesweeping. On trials all destroyers on 1-1.5kts exceeded contract speed (for example, Orella reached 35.9kts). All ships were arranged for service in various climatic conditions, from high latitudes to tropics, but because of weak hull construction have been recognised by unsuitable for service in Antarctic because of what in this region it was necessary to use older ships of Almirante Lynch class.    Serrano and Orella arrived to Chile 22.2.1929, remaining in September of the same year.
