HMS Onyx (J221) was a steam turbine-powered Algerine-class minesweeper during the Second World War.

Design and description

The turbine-powered ships displaced 850 long tons (860 t) at standard load and 1,125 long tons (1,143 t) at deep load. The ships measured 225 feet (68.6 m) long overall with a beam of 35 feet 6 inches (10.8 m). The turbine group had a draught of 11 feet (3.4 m). The ships' complement consisted of 85 officers and ratings. [1]

The ships had two Parsons geared steam turbines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,000 indicated horsepower (1,500 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). They carried a maximum of 660 long tons (671 t) of fuel oil that gave them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 10 knots (19 km/h; 12 mph). [1]

The Algerine class was armed with a QF 4 in (102 mm) Mk V anti-aircraft gun [2] and four twin-gun mounts for Oerlikon 20 mm cannon. The latter guns were in short supply when the first ships were being completed and they often got a proportion of single mounts. By 1944, single-barrel Bofors 40 mm mounts began replacing the twin 20 mm mounts on a one for one basis. All of the ships were fitted for four throwers and two rails for depth charges. [1]

Construction and career

The ship was ordered on 15 November 1940 at the Harland & Wolff at Belfast, Northern Ireland. She was laid down on 24 November 1941 and launched on 27 October 1942. The ship was commissioned on 26 March 1943. [3]

On 5 April 1967, she was put on the disposal list and sold to BISCO for scrap.
