Design and description

A British design, the Bangor-class minesweepers were smaller than the preceding Halcyon-class minesweepers in British service, but larger than the Fundy class in Canadian service. [3] [4] They came in two versions powered by different engines; those with a diesel engines and those with vertical triple-expansion steam engines. [3] Ungava was of the latter design and was larger than her diesel-engined cousins. Ungava was 180 feet (54.9 m) long overall, had a beam of 28 feet 6 inches (8.7 m) and a draught of 9 feet 9 inches (3.0 m). [3] [4] The minesweeper had a displacement of 672 long tons (683 t). She had a complement of 6 officers and 77 enlisted. [4]

Ungava 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). The minesweeper could carry a maximum of 150 long tons (152 t) of fuel oil. [3]

Ungava was armed with a single quick-firing (QF) 4-inch (102 mm)/40 caliber Mk IV gun mounted forward. [3] [lower-alpha 1] For anti-aircraft purposes, the minesweeper was equipped with one QF 2-pounder Mark VIII and two single-mounted QF 20 mm Oerlikon guns. [3] [4] As a convoy escort, Ungava was deployed with deployed with 40 depth charges launched from two depth charge throwers and four chutes. [3] [5]

Service history

Ungava was ordered as part of the 1939–40 shipbuilding programme. The vessel's keel was laid down on 24 April 1940 by North Vancouver Ship Repairs Ltd. at North Vancouver and the minesweeper was launched on 9 October 1940. She was commissioned into the Royal Canadian Navy on 5 September 1941 at Vancouver. [6]

After working up, Ungava was assigned to Halifax Force. She remained with the unit until May 1943 when she was ordered to join Gaspe Force, escorting convoys through the Saint Lawrence River. Later that year in December, she transferred back to Halifax Force and served with that unit for another five months. In May 1944 she transferred to Sydney Force, spending the rest of the year with that unit before returning to Halifax Force in February 1945. [6]

Ungava served with the Halifax Force until April 1945, when she underwent a refit at Liverpool which lasted until May 1945. After returning from workups, she was used for miscellaneous duties along the eastern coast until being paid off on 3 April 1946. [6] She was sold to T. Harris of Barber, New Jersey to be broken up in 1947. [7] [8]
