HMS Ardrossan (J131)

HMS Ardrossan was a Bangor-class minesweepers built for the Royal Navy during the Second World War.

Design and description
The Bangor class was designed as a small minesweeper that could be easily built in large numbers by civilian shipyards; as steam turbines were difficult to manufacture, the ships were designed to accept a wide variety of engines. Ardrossan displaced 656 LT at standard load and 820 LT at deep load. The ship had an overall length of 174 ft, a beam of 28 ft and a draught of 10 ft. The ship's complement consisted of 60 officers and ratings.

She was powered by two Metrovick-Curtis geared steam turbines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2000 shp and gave a maximum speed of 16 kn. Ardrossan carried a maximum of 160 LT of fuel oil that gave her a range of 2800 nmi at 10 kn.

The turbine-powered Bangors were armed with a 3 in anti-aircraft gun and a single QF 2-pounder (4 cm) AA gun. In some ships the 2-pounder was replaced a single or twin 20 mm Oerlikon AA gun, while most ships were fitted with four additional single Oerlikon mounts over the course of the war. For escort work, her minesweeping gear could be exchanged for around 40 depth charges.

Construction and career
Ardrossan was built by Blyth Shipbuilding Company, at Blyth, Northumberland and launched on 22 July 1941. Thus far she has been the only ship of the Royal Navy named after the Scottish town of Ardrossan. She had a relatively quiet wartime career and was sold on 1 January 1948 for breaking up. She arrived at the breaker's yard at Thornaby-on-Tees on 19 August 1948.
