Design and description

Main article: Algerine-class minesweeper

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

Service in the Royal Navy

The ship was ordered on 15 November 1940 at the Harland & Wolff at Belfast, Ireland. She was laid down on 21 July 1941 and launched on 27 May 1942. She was commissioned on 9 September 1942. ^[3]

Service in the Belgian Navy

Cadmus was renamed Georges Lecointe (after Belgian polar explorer Georges Lecointe) and was commissioned on 31 January 1950. ^[4]

In 1959, she was decommissioned by the Navy and on 24 April 1960, she was sold to J. Desmedt Burcht Belgium. Her scrapping process started on 19 May. ^[4]
