The Russians are slowly building up their modern frigate fleets. They are working on three separate classes for their main fleets (Not including the Caspian Flotilla that has a separate corvette).
Admiral Gorshkov 417 FFG, 5,500 tons full load
(1 commissioned, 2nd fitting out, 3rd building)
12-15 vessels planned for Northern and Pacific Fleets to replace the sovs and Krivaks .
Admiral Grigorovich 745 FFG, 4,050 tons fuill load
(1 commissioning, 2nd fitting pout, 3rd building)
6 planned for Black Sea Fleet
Steregushchy 530 FFG 2,200 tons full load.
(5 commissioned, 1 fitting put, 2 more building)
8 planned for Baltic fleet
They have built commissioned 7 vessels, have three fitting pout, and four building. This makes 14 FFGs commissioned, fitting out or building altogether, which is pretty good for the Russians given their circumstances...but thney are not without problems with various systems.
