Twin Screw Fast Frigate ordered on 19th January 1943 from Charles Hill of Bristol and laid down on 29th September 1943 as Yard No 453 (Admiralty Job No 453). The ship was launched on 25th March 1944 by Mrs G Luckwell, wife of the Yard Manager, and was the first RN ship to carry this name. She -was completed on 25th June 1944 in 274 days which was faster than the time taken for the prototype LOCH FADA built by John Brown at Clydebank. This new type of frigate had been adopted by the civil community of Edmonton then in the County of Middlesex and now part of the Greater London Borough of Enfield after a WARSHIP WEEK National Savings campaign in March 1942. Although this shipyard had previously built FLOWER Class Corvettes and RIVER Class Frigates this ship was the first of this Class builtt in Bristol and using more extensive prefabrication. See General Information.
