Russian maritime agency Rosmorrechflot has sued state-owned United Shipbuilding Corporation (USC) over a delayed icebreaker.

The agency wants RUB 667m ($10.21m) for the late arrival of the Victor Chernomyrdin, the Kommersant daily said.

It was built at USC's Baltic Shipyard and originally set for delivery at the end of 2015 at a price of RUB 7.94bn.

Due to the devaluation of rouble, this was extended to 2017-2018 and the cost of the project increased by RUB 1.5bn.
