Design
Main article: Project 97 icebreaker
Soviet Navy Project 97P icebreaking patrol vessel Ivan Susanin in 1985

These ships are modified versions of the Project 97 icebreakers. They are armed with a twin 76 mm (3 in) AK-726 gun mounting forward and two 30 mm AK-630 close-in weapon systems aft as well as having a helipad and surveillance radar. The twin 76 mm AK-726 gun are controlled by MR-105 Turel ("Hawk Screech") fire-control radar. On the Soviet Navy icebreaking patrol vessels Ivan Susanin and Ruslan armament was removed.[1]
