[edit] History

Development of the class started in 1963. Five hull designs and over thirty propulsion variants were looked at during development. At the time, the electronics of the vessels were state of the art and attracted international attention. Both vessels were built by Wärtsilä's Hietalahti shipyard in Helsinki. In 1985-86 both ships were refitted, with the entire fire-control and communications systems being updated. FNS Karjala is as of 2002 berthed at the maritime museum Forum Marinum in Turku as a museum ship next to Suomen Joutsen. FNS Turunmaa has been stripped of armaments and serves as a flotating machine shop and training ship for Satakunta Polytechnics. Neither vessel is currently owned by the Finnish Navy.
