A contract for the construction of two Project 23550 multipurpose icebreakers was awarded by the Russian Ministry of Defence to Admiralty Shipyards in April 2016.
Construction on the lead vessel in the class, Ivan Papanin, began in September 2016 and the keel-laying ceremony was held in April 2017. The ship is expected to be delivered to the Russian Navy by 2021.
Mission capabilities of Ivan Papanin-class icebreakers
The Ivan Papanin-class Arctic patrol vessels are ideal for missions such as monitoring and protection of Russian Arctic waters, rescue, escorting of ships in polar waters, transportation of special equipment, towing of ships in the port of detention, and maintenance and support for service vessels.
The ships can also be used to offer protection for vessels operating in polar waters from air, sea and coastal targets.
Design and features
The Ivan Papanin-class polar icebreakers will be built with a strengthened and reinforced hull to enable them to move through sea ice. Each vessel will have a length of approximately 110m and width of 20m.
With a displacement of 8,500t, the vessels will be able to accommodate up to 60 crew members with an option to carry an additional 50 members.
A flight deck and hangar will be fitted on the main deck towards the stern to support the operations of a single Ka-27PS anti-submarine helicopter, a Ka-27PL search-and-rescue helicopter or an unmanned aerial vehicle.
The vessel will house two high-speed patrol boats of type Raptor (Project 03160)-class of the Russian Navy. Located on the starboard side of the ship, the boats can be used to conduct a variety of tasks such as search-and-rescue, anti-terrorism, patrolling and anti-sabotage.
The bridge section will be situated amidships, providing operators with an unobstructed view of the sea. A fire control system and range of radars and communication antennae will be placed on top of the bridge structure to provide safe navigation of the vessel.
Armament of Project 23550-class icebreakers
The Russian Navy’s Project 23550-class polar icebreaker ships will be armed with one AK-176MA automatic naval gun system developed by JSC CRI Burevestnik.
Mounted on the bow, the artillery gun will provide defence against sea, air and shore-based targets at a distance of up to 15.7km. It has a rate of fire between 120 and 131 rounds a minute.
The armament also includes four Kalibr-NK anti-ship / anti-submarine / land-attack subsonic cruise missiles, which will be launched from two quadruple canister missile launch systems located at the stern of the ship.
Propulsion and performance
Each vessel in the Ivan Papanin-class will be powered by two electric motors rated at 4,080hp each. It will also be equipped with two bow thrusters and azipods to perform safe manoeuvres at sea.
It will have a speed of up to 16k and range of up to 6,000 miles. It will be able to operate in the Arctic zone for up to 60 days.
The icebreaker vessels will be capable of moving and navigating through 1.5m-thick sea ice crusts.
