BANGOR-Class Minesweeper fitted with Diesel propulsion machinery ordered on 6th July
1939 from Harland and Wolff and laid down at Govan. Glasgow as Job Number 1020 (Yard No. 1039) on 19th
September 1939 with sister ship to be named BLACKPOOL. She was launched 23rd
May 1940 and build was completed on 3rd February 1941. She was the 1st RN ship
to carry this name, which like others of the Class built in UK was that of a

community of Bangor, North Wales after a successful WARSHIP WEEK National
Savings campaign in March 1942.
