Hämeenmaa was a Finnish Riga class frigate. However the class was called the Hämeenmaa-class in Finland since the ship had some unique modifications (i.e. British submarine hunting equipment). The two 37 mm twin guns were also replaced with two 40 mm single AA guns in 1975.

Hämeenmaa was in Finnish Navy service between 1964-1987. The sister ship Uusimaa was decommissioned in 1979 and cannibalized for spare parts for the Hämeenmaa. Both ships had already served a few years in the Soviet Navy before sale to Finland.

Hämeenmaa was rebuilt into a minelayer in the 1980s. A communications central replaced the Hedgehog mounting. The torpedo tubes were removed. A bow twin 30 mm AK-230 was added. Hämeenmaa was decommissioned in 1987.
