Project history

Bangor class minesweepers have appeared as alternative to Halcyon class ships which, according to Admiralty, because of relatively large dimensions did not approach for a mass building. Deciding about creation on base of Halcyon 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 diesel engine 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 VTE, and again in two variants: with compact high-speed (a rotational speed of shafts was almost same, as well as at 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 has completed for their Navy.

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, instead of it more light 76mm AA gun was installed. Nevertheless, stability of Bangors, especially diesel variant, was considered in Britain as insufficient.

Modernizations

1943 - 1944, all early ships had 1 x 1 - 40/39 2pdr QF Mk VIII and / or (1 - 3) x 1 - 20/70 Oerlikon Mk II/IV as close range AA.
