Project 22220 icebreaker, sometimes referred as LK-60Ya ((ロシア語:ЛК-60Я)), is a class of three nuclear-powered icebreakers under construction at Baltic Shipyard in Russia. The first ship, ''Arktika'' (''Арктика'' - Arctic), was laid down in November 2013 and is expected to enter service in 2017. When completed the ship will become the world's biggest and the most powerful icebreaker surpassing the current leader, which is the Russian icebreaker 50 Years of Victory. 〔http://www.ship-technology.com/projects/arctic-project-22220-lk-60-nuclear-icebreaker/〕 Project 22220 class ships will have an overall length of 173m and breadth of 34m. The design draught is 10.5m and a minimal operating draught is 8.55m. The dual-draft design will enable ships to operate in both arctic waters and mouths of polar rivers. Project 22220 ships have a displacement of 33,540t.〔http://www.rosatom.ru/en/presscentre/news/006c2300442f03c0bf2abffbf29b353a〕 Project 22220 ships will be equipped with two RITM-200 nuclear reactors, with a thermal capacity of 175MW each. The propulsion power of this class of ships will be 60MW which is why this class is sometimes referred as LK-60. Project 22220 has been classified by the Russian Maritime Register of Shipping (RMRS) as the ice class, ''Icebreaker9''. The maximum icebreaking capability of 22220 class vessels is 2.8 m. The vessels are intended for the Northern Sea Route along the Russian Arctic coast. The 2nd ship of this class, the ''Sibir'' - (''Сибирь'' - Siberia), was laid down on 26 May 2015 at Baltic Shipyard. 〔http://en.portnews.ru/news/200357/〕 In may 2015 it was also reported that Russia had made a principal decision on the development of the conceptual design for the new nuclear-powered icebreaker. According to Sergey Kirienko, Director General of State Atomic Energy Corporation Rosatom, the new icebreaker could move across the Arctic ice of any thickness up to 4.5 m. The new icebreaker will reportedly have the propulsion power of 110MW. 〔http://en.portnews.ru/news/200352/〕 If build this new icebreaker would be almost twice as powerful as the icebreakers of the project 22220. == List of project 22220 icebreakers == ==References== 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Project 22220 nuclear-powered icebreaker」の詳細全文を読む スポンサード リンク
