Knowledge 1: Jurmo-class landing craft
The Jurmo-class landing craft is a type of military transport in use by the Finnish Navy. The manufacturer Marine Alutech designates it as Watercat M12. [SEP] Knowledge 2: Finnish Navy
When the Winter War broke out the Finnish Navy moved to occupy the de-militarized Åland Islands and to protect merchant shipping. In the first month of the war, battles between Soviet ships and Finnish coastal batteries were fought at Hanko, Finland, Utö and Koivisto. At Koivisto and Hanko, the batteries forced Soviet battleships to retire with damage. Finnish efforts to use submarines ("Vesikko" and "Saukko") to sink Soviet capital ships failed. In December 1939 the ice became so thick that only the ice-breakers could still move. The two coastal defence ships were moved to the harbour in Turku where they were used to strengthen the air-defences of the city. They remained there for the rest of the war.
