Design and description

The Aberdare sub-class were enlarged versions of the original Hunt-class ships with a more powerful armament. The ships displaced 750 long tons (760 t) at normal load^[1] and 930 long tons (940 t) at full load.^[2] They measured 231 feet (70.4 m) long overall with a beam of 28 feet 6 inches (8.7 m) and a draught of 7 feet 6 inches (2.3 m). The ships' complement consisted of 74 officers and ratings.^[1]

The ships had two vertical triple-expansion steam engines, each driving one shaft using steam provided by two Yarrow boilers. The engines produced a total of 2,200 indicated horsepower (1,600 kW) and gave a maximum speed of 16 knots (30 km/h; 18 mph). They carried a maximum of 185 long tons (188 t) of coal^[1] which gave them a range of 1,500 nautical miles (2,800 km; 1,700 mi) at 15 knots (28 km/h; 17 mph).^[3]

The Aberdare sub-class was armed with a quick-firing (QF) four-inch (102 mm) gun forward of the bridge and a QF twelve-pounder (3-inch (76.2 mm)) anti-aircraft gun aft.^[1] Some ships were fitted with QF six-pounder (2.2-inch (57 mm)) Hotchkiss guns or QF three-pounder (1.5-inch (37 mm)) Hotchkiss guns in lieu of the twelve-pounder.^[3]

Construction and career

Wem, the first ship of her name in the Royal Navy, was laid down with the name of Walmer by William Simons & Company at their shipyard in Renfrew, Scotland. The ship was renamed on 25 June 1918 and launched on 12 September 1919. She was sold to The Cutch SN Co. on 22 April 1921 and renamed Deshalpur. The ship was broken up about 1927.^[4]
