Project history

Design of "River" class frigate was developed in 1941 when it became clear, that for service in Atlantic escorts larger than "Flower" class corvettes are required. Significantly increased dimensions have allowed to improve seaworthiness and habitability, to place additional armament and to fit twin-shaft machinery (actually doubled machinery of "Flower" class corvettes) and to increase speed to 20kts. 5 ships received more powerful turbine machinery. Originally known as "twin-screw corvettes", "River" class ships, as well as their predecessors, were created under merchant standards, but their hulls had lines more habitual for a warship, L/B ratio was increased from 6 to 8. Thus the building technology, as well as  corvettes, as much as possible adapted for usage on the yards which do not have experience of naval shipbuilding. First 24 British-built ships, besides ASW armament, were equipped with the minesweeps. On the subsequent ships it was absent, and fuel stowage has been increased from 440 to 646ts of oil due to rejection of anti-roll tanks. Ships of 2nd group were built in Canada under British order, 10 from them intended for transfer to US Navy which during this period felt the big requirement in escorts. However by the moment of completing of frigates intended to USN they have appeared not necessary, as in the USA own program of building of the similar ships has been developed. Only 2 were transferred really to USN, remaining 8 (Barle, Cuckmere, Evenlode, Findhorn, Inver, Lossie, Parret and Schiel) were transferred to Royal Navy by lend-lease. The remaining 25 Canadian-built ships became a part of RCN.
