the demanding mine clearance operation. The operation lasted until 1950. There were many casualties among the clearance crews. The Cold War era The war time fleet was replaced in the 1950s and 1960s. Due to Finland's neutrality she tried to balance her purchases of equipment between the two blocs and also tried to produce its own vessels. A (Matti Kurki) for training purposes, two fast patrol boats (Vasama 1 and Vasama 2) and four s were bought from the UK, two s ( and ) and four Osa II-class fast attack craft (s) were obtained from the Soviet Union. Some of the vessels, such as two s ( and ) and the Nuoli-class fast attack craft were produced domestically. The Paris peace talks in 1947 resulted in a treaty that limited the offensive capability of the Finnish military. For the navy, this meant a limitation to a fleet of no more than 10,000 tons and 4,500 personnel. As for the weaponry, torpedoes, submarines, mines and missiles were forbidden. The restrictions were eased in the 1960s and missiles and mines were allowed. The torpedo restriction was not either fully exercised as the Riga-class frigates were equipped with torpedoes and a number of torpedo boats were manufactured as gunboats that could quickly be converted to carry torpedoes. Torpedoes were re-introduced in 2018. The Cold War limitations are no longer in place (they were nullified with the breakup of the Soviet Union), but the size of the navy has still remained roughly the same size (with the exception of tonnage). Current status In the late 1990s, the Finnish Navy was developing a new missile squadron called Laivue 2000 (). At first it was supposed to consist of two Hamina-class missile boats (already built at this date) and four hovercraft. The Navy experimented with one prototype hovercraft, but announced in 2003 that the Tuuli class would not enter active operations and that no more of them would be built. Instead two new Hamina-class missile boats were built, and the extra weaponry from the hovercraft were installed on the Hämeenmaa-class minelayers. The cable layer and pollution control vessel were replaced in 2011 by a new multipurpose vessel built by the Uudenkaupungin Työvene shipyard. A new icebreaking oil spill response vessel was named on 8 March 2011. The 1979-built minelayer was decommissioned in 2013, after which the minelayer Hämeenmaa took over the role of flagship of
