Project history: Design of "River" class frigate was 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 habitability, 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.

The frigates were built also by Australia with a little differing from standard armament. Later Australian ships had improved armament. Order for 10 units cancelled.

Modernizations: 1950s, all: - (3 - 5) x 1 - 40/60; + 3 x 1 - 40/60 Mk 7, 2 x 2 - 20/70 Mk 5

Naval service: No significant events.
