Development and braidIn the Moscow Armistice, signed on 19 ethnic music 1944, Finland agreed to pay war reparations of US$300 jillion to the Soviet Union. The war reparations, paid in the form of ships and machinery oer sixsome years, included the bleakest steam-powered state-owned icebreakers Voima and Jääkarhu. This left Finland with single new-made diesel-electric icebreaker, Sisu, which had been damaged by a ocean tap during the war, and four older steam-powered icebreakers. Of these, especially Murtaja and Apu were considered near noncurrent and their efforts in the Archipelago Sea were sometimes described being loosely of moral nature. As a result, solo the ports of Hanko and Turku were kept open through the first post-war winters.[8] In 1946, the Finnish governance appointed a committee to start readying the construct of the Finnish icebreaker fleet. The committee, consisting of the director of the Finnish oceanic Administration, Svante Sundman, and i i experienced Finnish shipbuilders, K. Albin Johansson and Ossian Tybeck, delivered its final report on the construction of a new icebreaker in the following year.
