Ship project history: Design of "River" class frigate is developed in 1941 when it became clear, that for service in Atlantic escorts are required larger than "Flower" class corvettes. Significantly increased dimensions have allowed to improve seaworthiness and conditions of habitability of crew, to place additional armament and to fit twin-shaft machinery (actually doubled machinery of "Flower" class corvettes) and to increase speed to 20kts. An exception made 5 ships which have received more powerful turbine machinery.

Originally known as "twin-screw corvettes", "River" class ships, as well as their predecessors, created on standards of merchant shipbuilding, but their hulls had outlines more habitual for a warship, and its slenderness has 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 construction of combat ships.

First 24 British-built ships, besides anti-submarine armament, were equipped with the minesweeping equipment. On the subsequent ships it was absent, and fuel stowage has been increased from 440 to 646ts of oil.

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 are 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) have supplemented Royal Navy by lend-lease. The remaining 25 Canadian-built ships were a part of RCN.

Modernizations: 1943 - 1944, all survived: DC stowage increased up to 150.

1943 - 1944, all survived ships: - (4 - 6) x 1 - 20/70; + 6 x 2 - 20/70 Oerlikon Mk II/IV or (4 x 2 - 20/70 Oerlikon Mk II/IV, 2 x 1 - 20/70 Oerlikon Mk II/IV)

1945, most survived Canadian-built frigates: - 2 x 1 - 102/40; + 1 x 2 - 102/45 QF Mk XVI
