Project history

Bangor class minesweepers were designed as alternative to Halcyon class ships which, according to Admiralty, because of relatively large dimensions did not suited for a mass building. Deciding about designing the smaller minesweeper have accepted in 1938. Designing was conducted quickly and already in the beginning of next year design in two variants has been approved: with diesels and with turbines. In the spring of 1939 order for first 10 ships was placed. With the beginning of hostilities mass building of Bangor class started. Many small private yards have been attracted in fulfilment of this program. Foreseeing difficulties which could be at the last in the absence of experience of building of ships with turbine or diesels, Admiralty have developed the design of Bangor with VTEs, and again in two variants: with compact high-speed (a rotational speed of shafts was almost the same, as well as on diesel-engined ship) and with more bulky, but habitual, slow-speed VTE. Last variant also became the most mass: British, Canadian and Indian yards have built 67 units, 4 more sister ships, laid down in Hong Kong, were captured by Japanese and completed for their Navy.

Except the ships with slow-speed VTE, 26 turbine-engined, 14 diesel-engined and only 2 minesweepers with high-speed VTE were built.

Conceived as the pure minesweepers carrying under the design only 4 DCs, Bangor at a completion phase have received the strengthened anti-submarine armament. Because of the overload which have arisen thus it was necessary to refuse from provided by the design 102mm gun, more light 76mm AA gun was installed instead. Nevertheless, stability of Bangors, especially diesel variant, was considered in Britain as insufficient.

From 50 VTE ships, built in Canada, 12 were ordered by RN, but half from them have transferred to Canadian fleet.

Modernizations

1943 - 1944, RN ships: - 1 x 4 - 12.7/62; + (1 - 3) x 1 - 20/70 Oerlikon Mk II/IV

1943 - 1944, RCN ships: + (1 - 3) x 1 - 20/70 Oerlikon Mk II/IV

Naval service

Esquimalt was sunk by German submarine U190 near Halifax 16.4.1945. All RCN ships were reclassified as coastal escorts in 1953.
