The first two ships will serve the Russian Navy, while the third and fourth will serve the Border Guards.
The Russian icebreakers carry many more weapons than the Norwegian Svalbard class or the Canadian Harry DeWolf class. Its main role is to patrol in the Arctic, that's why they are specially designed to operate in arctic climates. The ship can get through ice up to 1.5m in thick.
The boat has a crew of 48, although it can carry up to 47 extra troops.
As for the weapons, the Ivan Papanin class features an AK-176MA 76mm naval gun and one vertical launcher of 8 shells that can shoot the Kalibr cruise missiles. The launcher can shoot the 3M14 cruise missiles against land targets at a maximum distance of 1,500km. Last, the 3M54 is also an available anti-ship cruise missiles option that has a maximum range of 440-660km and can be equipped with nuclear warheads.
There's also enough space for a military helicopter like the Ka-27 or the Ka-32.
The icebreakers are so big that feature two Raptors high-speed patrol boats. These boats can operate in different roles like rescue, transport, patrol, and more.
Last, let us inform you that Ivan Papanin class icebreakers are not nuclear but work with a diesel-electric propulsion system with two Kolomna 28-9DG diesel engines.
