HMS Bangor (J00)

Bangor Class Minesweepers were employed as Fleet (i.e. Open Water) minesweepers for the Royal Navy. Over a hundred were built, mainly between 1940 and 1942. The first two were launched on the same day (19 February 1940) at Belfast, Northern Ireland. Additional vessels were built during the war for the Royal Canadian Navy (RCN) and the Royal Indian Navy (RIN).

Their small size made them poor sea-boats, worse even than the Flower class corvettes; the diesel versions were the worst and the slow-speed reciprocating the best. Their shallow draft (9 feet, 2.7 m) made them unstable and their short, stubby hulls meant that they tended to bury their noses into head seas.

They were also very crowded, cramming up-to 90 ratings and six officers into a hull originally intended for a total of 40 officers and men.

[edit] Variants

The original intent of the Bangor class minesweeper design was to provide a coastal equivalent of the Halcyon class minesweeper but the realities brought to light by the start of the war caused a modification of the design before construction started.

The need for fast construction coupled with the limitations of engineering resources resulted in several variations existing based on the availability of propulsion machinery. They all had twin screws, but the machinery was a mix of steam turbine, slow-speed steam reciprocating, high-speed steam reciprocating and diesel. The diesel powered examples were about 20 feet (6 m) shorter than the rest as they had no need for boiler rooms. Displacement varied with propulsion machinery in the range 590 to 672 tons.

[edit] The current HMS Bangor

The Bangor class tradition continues in the modern Royal Navy with HMS Bangor (M109), the ninth of the Sandown class minehunters. She was built by Vosper Thornycroft UK Ltd at Woolston, Southampton. She was launched on the 16 April 1999 by Lady Lisa Spencer. She carries the battle honours of the old J00 from the Dieppe Raid in 1942, Normandy and the English Channel in 1944. She has since earned her own battle honour for operations at Al Faw in 2003.
