The Atle class comprises five icebreakers built for the Swedish and Finnish Transport Agency. The two Finnish ships, Urho and Sisu, are sometimes considered a separate class, but all are operationally identical.[1]
The ships were built by Wärtsilä Helsinki Shipyard in Finland and entered service in the mid to late 1970s.[1] The maneuvering system, incorporating dual rudders and dual bow propellers, represented significant technical innovation. They are also notable for their high level of crew comfort (for their time), to a point where Urho has served the Finnish government as a VIP transport.
