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. Originally known as "twin-screw corvettes", "River" class ships, as well as
their predecessors, created by
merchant standards, but their
hulls had lines more habitual for a warship, and its L/B
ratio 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 naval shipbuilding. Frigates of 3rd group were built in Canada for own
navy and differed from
earlier ships by replacement of two single-purpose 102mm/40 guns by one
twin 102mm/45 mount on a forecastle and 76mm gun aft (latter was
installed not on all
ships). Order for
20 more frigates of 3rd group was cancelled in December 1943 - January, 1944.
