in july 2004, the saint petersburg-based baltic shipyard won an international tender for the construction of two 16-megawatt diesel-electric icebreakers for rosmorport, a state-owned company established in 2003 to manage russia's port infrastructure and operate its fleet of diesel-powered icebreakers. although the shipyard had built five "arktika"-class nuclear-powered icebreakers in 1975–1992 and had the sixth under construction at the time, these would be the first non-nuclear icebreakers built on a russian shipyard in over three decades and the first new icebreakers ordered following the dissolution of the soviet union.
