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.
