Having begun another Atlantic cruise on 22 March that would last until 24 November, Admiral Isakov participated in Exercise Laguna, tracking possible NATO submarine movements in the North Atlantic alongside Kresta I-class missile cruiser Sevastopol and her sister ship Admiral Makarov between 12 and 29 May. During the exercise, a NATO submarine was detected during the exercise, and the crew of her Ka-25 made their first night landing on a moving ship.
