Design and description

The Halcyon class designed as a replacement for the preceding Hunt class and varied in size and propulsion. Halcyon displaced 815 long tons (828 t) at standard load and 1,370 long tons (1,390 t) at deep load. The ship had an overall length of 245 feet 9 inches (74.9 m), a beam of 33 feet 6 inches (10.2 m) and a draught of 8 feet 3 inches (2.5 m).

She was powered by two vertical compound-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 1,770 shaft horsepower (1,320 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). Halcyon carried a maximum of 243 long tons (247 t) of fuel oil that gave her a range of 7,200 nautical miles (13,300 km; 8,300 mi) at 10 knots (19 km/h; 12 mph). The ship's complement consisted of 80 officers and ratings.

Halcyon was armed with two QF 4-inch (10.2 cm) guns; the forward gun was in a high-angle mount while the aft gun was in a low-angle mount. She was also equipped with eight .303-inch (7.7 mm) machine guns. Later in her career, the rear 4-inch gun mount was removed as were most of the .303 machine guns, one quadruple mount for Vickers .50 machine guns was added as were up to four single or twin mounts for 20 mm Oerlikon anti-aircraft guns. For escort work, her minesweeping gear could be exchanged for around 40 depth charges.

Construction and career

Halcyon was built by John Brown Shipbuilding & Engineering Company Ltd., at Clydebank, in Scotland. She was laid down on 27 March 1933 and launched on 20 December of the same year. She was commissioned on 18 April 1934.

During the Second World War, Halcyon served as the lead ship in the 1st Minesweeper Flotilla and saw service during the Arctic convoys, including Convoy PQ-17 in 1942. She also saw service during Operation Neptune, the naval component of Operation Overlord (D-Day, 1944). Halcyon was sold for scrapping at Milford Haven on 19 April 1950 after 16 years service with the Royal Navy.
