HMS Bradfield was a Hunt-class minesweeper built for the Royal Navy during World War I, although she was not completed during the war. The ship was sold out of service in 1920.

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

Bradfield, the first ship of her name in the Royal Navy, was built by the Ayrshire Dockyard Company at their shipyard in Irvine, North Ayrshire. The ship was launched on 14 May 1919. She was sold in October 1920 and renamed Champavati. ^[4]
