The Ivan Susanin class is a group of icebreaker patrol ships operated by the Russian maritime border guard. The Soviet designation is Project 97P. The ships are also known as the Aysberg-class patrol icebreakers.

Design

These ships are modified versions of the  Dobrynya Nikitich-class civilian icebreaker. They are armed with a twin 76 mm (3 in) gun mounting forward and two AK-630 guns aft as well as having a helicopter pad and surveillance radar. The two 30 mm guns are controlled by two SP-521 Kolonka-2 ring sight fire control directors.

Ships

Eight ships were built between 1972 and 1981 by the Admiralty Shipyard in Leningrad. Four have been retired and four remain operational as of 2018.
