ASW requirements support larger Soviet destroyers

A navy that places submarines at the center of its doctrine also takes the enemy submarine threat seriously. Gorshkov can use the range of required ASW weapons and equipment to justify larger surface ships. Soviet difficulties in miniaturizing circuits and computer components add to the problem, as some promising development paths prove unsuccessful. Only four Kildins enter service, and later frigates surpass them in capability. Their value lies in the weapons and operational experience they provide as the Soviet Navy builds a blue-water fleet.
