The Riga class was the NATO reporting name for class of frigates
built for the Soviet Navy in the 1950s. The Soviet designation for these ships
was Storozhevoi Korabl (escort ship) Project 50 Gornostay (Ermine stoat).
The class introduced high pressure steam turbines and new radars into Soviet service.
The bridge, gun turrets, and magazines were covered in 8 mm armour. The main armament
comprised three single dual-purpose 100 mm guns with remote power control and
a single Yakor fire control system. They had conventional weaponry consisting
of three standard antiaircraft / mixed turrets complemented by dual 37mm mounts,
an anti-ship 533-mm torpedo tubes, and one MBU-200 ASW rocket launcher. The machinery
comprised two TV-9 steam turbines with two boilers.
There was a modernisation
programme in the late 1950s early 1960s. This included fitting anti-submarine
rocket launchers (RBU-2500) new radar and adding permanent ballast for improved
The Project 50 Riga class was a rather simplistic and straight
forward design. With their basic capabilities, moderate size and ease of operation,
they made perfect export vessels for smaller navies where such ships could easily
fill the multi-purpose role, taking the place of large minesweepers and actual
destroyers. A total of 68 ships were built by Nikolayev yards (20 ships), Komsomolsk-on-Amur
(7 ships) and Kaliningrad (41 ships), distributed among the four fleets.
