Project 22220 icebreaker
The first ship, ("Арктика" – Arctic), was laid down in November 2013 and is expected to enter service in 2019. Launched on 16 June 2016, the ship will be the world's largest and the most powerful icebreaker surpassing the "50 Let Pobedy".
The second ship of this class, "Sibir" – ("Сибирь" – Siberia), was laid down on 26 May 2015 at Baltic Shipyard. On 1 July 2016, the hull of "Sibir", one third of the ship and weighing 3,500 t, was shifted to the place of the launched "Arktika" icebreaker, where construction will be completed. The shift made place for the start of the construction of the hull of the icebreaker "Ural" – ("Урал" – Ural). Construction of the Ural started on 25 July 2016.
HMS Ontario (1780)
HMS "Ontario" was a British warship that sank in a storm in Lake Ontario on 31 October 1780, during the American Revolutionary War. She was a 22-gun snow, and, at in length, the largest British warship on the Great Lakes at the time. The shipwreck was discovered in 2008 by Jim Kennard and Dan Scoville. "Ontario" was found largely intact and very well preserved in the cold water. Scoville and Kennard assert that "the 80-foot sloop of war is the oldest shipwreck and the only fully intact British warship ever found in the Great Lakes."
