NRP Lima was one of five Douro-class destroyer built for the Portuguese Navy during the 1930s. She remained in service until the early 1960s.

Design and description[edit]

The Douro-class ships were designed by the British shipbuilder Yarrow and were based on Ambuscade, a prototype destroyer built for the Royal Navy in 1926 by Yarrow.[1] They were 323 feet (98.45 m) long overall, with a beam of 31 feet (9.45 m) and a draught of 11 feet (3.35 m). The ships displaced 1,219 long tons (1,239 t) at standard load and 1,563 long tons (1,588 t) at full load.[2]

The Douros powered by two Parsons-Curtis geared steam turbines, each driving one propeller shaft using steam provided by three Yarrow boilers. The turbines, rated at 33,000 shaft horsepower (25,000 kW), were intended to give a maximum speed of 36 knots (67 km/h; 41 mph).[a] The destroyers carried enough fuel oil to give them a range of 5,400 nautical miles (10,000 km; 6,200 mi) at 15 knots (28 km/h; 17 mph).[2][4]

Armament was similar to contemporary Royal Navy destroyers, with a gun armament of four 4.7 in (120 mm) Vickers-Armstrong Mk G guns, and three 2-pounder (40 mm (1.6 in)) Mk VIII anti-aircraft guns. Two quadruple banks of 21-inch (533 mm) torpedo tubes were carried, while two depth charge throwers and 12 depth charges constituted the ships' anti-submarine armament. Up to 20 mines could be carried. The ships' complement consisted of 147 officers and men.[2]

Construction and career[edit]

The five destroyers carried out patrols to defend Portugal's neutrality during the Second World War. Their anti-aircraft armament was revised during 1942–1943, with the 40 mm guns and one of the banks of torpedo tubes replaced by six 20 mm cannon.[3][1] The ships were refitted by Yarrow from 1946 to 1949, with the machinery refurbished, anti-aircraft armament again revised to three Bofors 40 mm gun in powered mounts and three 20 mm cannon. Sonar and British Type 285 and Type 291 radars were fitted.[5]

Notes[edit]

  1. ^ Lima reached 36.36 knots (67.34 km/h; 41.84 mph) from 31,110 shaft horsepower (23,200 kW) during trials.[3]
