The Douro class of destroyers included five ships used by the Portuguese Navy (Marinha Portuguesa) between 1933 and 1967 and two used by the Colombian Navy (Armada de la Repúbica de Colombia).
It is to note, that, in Portugal, this class of destroyers is usually referred to as the Vouga class, with the term Douro class being usually employed to designate the previous class of Portuguese destroyers also known as Guadiana class.
In 1930, the Portuguese navy drew up a 10 year shipbuilding programme to replace its aging fleet, with planned purchases including two cruisers, twelve destroyers and a number of submarines and sloops. The competition for the design for destroyers was won by Yarrow Shipbuilders beating bids from Thornycroft and Italian shipyards. An order was placed for four ships on 12 June 1931, with two ships, Vouga and Lima to be built by Yarrows in the UK and the remaining ships, Tejo and Douro to be built at Lisbon with machinery to be supplied by Yarrow. A fifth ship, Dão, again to be built in Lisbon using Yarrow-supplied machinery, was ordered on 18 January 1933.
Yarrow's design was based on Ambuscade, a prototype destroyer built for the Royal Navy in 1926. The ships were 323 feet (98.45 m) long overall and 307 feet (93.57 m) between perpendiculars, with a beam of 31 feet (9.45 m) and a draught of 11 feet (3.35 m). The ship displaced 1,219 long tons (1,239 t) standard and 1,563 long tons (1,588 t) full load. Three Yarrow boilers fitted with air pre-heaters and superheaters supplied steam at 400 pounds per square inch (2,800 kPa) to geared steam turbines, driving two propeller shafts and generating 33,000 shaft horsepower (25,000 kW), giving a speed of 36 knots (67 km/h; 41 mph). Sufficient fuel was carried to give a range of 5,400 nautical miles (10,000 km; 6,200 mi) at 15 knots (28 km/h; 17 mph).
