Design and description edit
The reciprocating group displaced 1,010–1,030 long tons (1,030–1,050 t) at standard load and 1,305–1,325 long tons (1,326–1,346 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). They had a draught of 12 feet 3 inches (3.7 m). The ships' complement consisted of 85 officers and ratings.[1]
The reciprocating ships had two vertical triple-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2,400 indicated horsepower (1,800 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 edit
Ossory was laid down by the Port Arthur Shipbuilding Co., Thunder Bay, Ontario, on 20 November 1943 and was launched on 3 October 1944.[3] She was completed on 29 September 1945.
Ossory commissioned too late for service in World War II, joining the 4th Minesweeping Flotilla in January 1946 and serving in the Fishery Protection Squadron from 1946–1947.[4] She was reduced to reserve at Portsmouth in 1948.[4]
Ossory was scrapped at Troon, Scotland from 4 March 1959.[5]
