Ships hunting a Kirov would be unavailable for North Atlantic convoys, attacks on Soviet bastions, Mediterranean operations, or other preferred NATO tasks. Even a very large alliance enters war with finite forces. Units in major refit, damaged ships, and vessels committed beyond recall do not contribute to the immediate battle. Soviet planners could place a conspicuous raider where it attracted escorts before hostilities began, although they could not control every source of NATO unavailability. As Western fleet numbers declined late in the Cold War, diverting a few worked-up destroyers, submarines, aircraft, or a carrier group could have an increasingly disproportionate effect.

Why available ships matter more than headline fleet size
A diversion works against the ships that are worked up, undamaged, nearby, and callable at the start of a war, not against a navy's paper total.
