Project 21900 and Project 21900M icebreakers (also referred as LK-16) are a series of five Russian icebreakers. Two project 21900 icebreakers (Moskva and Sankt-Peterburg) were built at Baltic Shipyard in Saint Petersburg in 2008 and three project 21900M icebreakers were built at Vyborg Shipyard in Vyborg and at Arctech Helsinki Shipyard in Helsinki. Two of the new vessels (Vladivostok and Murmansk) were entered service in 2015 and the last one (Novorossiysk) in 2016. The construction of the 21900M class icebreakers was conducted under the Federal Target Programme "Development of the Transport System of Russia (2010 – 2015)".
The main tasks of the project 21900/21900M class vessels are icebreaking and assisting of heavy-tonnage vessels in ice, towing of vessels and other floating structures both in ice and in open water. The vessels will also be used for fire fighting on floating objects and other facilities, assisting vessels in distress in ice and open water and cargo transportation.
According to Sergey Shishkin, head of RS Classification Division, the new project 21900M class ships features an improved design when compared to the older project 21900 class icebreakers. The newer project 21900М vessels have higher performance characteristics taking into consideration the service experience of previous icebreaker projects when ensuring icebreaker escort during winter navigation in the Gulf of Finland. Project 21900M has been classified by the Russian Maritime Register of Shipping (RMRS) as the ice class, Icebreaker6. The maximum icebreaking capability of 21900/21900M class vessels is 1.5 m. The vessels are intended for the Baltic Sea and the Northern Sea Route along the Russian Arctic coast.
The first Project 21900 icebreaker, Moskva, was delivered on 11 December 2008. She was the first Russian non-nuclear icebreaker built on a domestic shipyard in 32 years. Prior to this, all large diesel-powered icebreakers had been built in Finland while the shipyards in the Soviet Union produced only a series of smaller port icebreakers.
