As of June 30, 2016, Destroyers, Light Cruisers, Torpedo Cruisers and Training Cruisers can now perform a preemptive Anti-Submarine Attack on enemy submarines. [[Isuzu#Second Upgrade|Isuzu Kai Ni]] can do preemptive attacks unconditionally; other light cruisers as well as destroyers, torpedo cruisers and training cruisers need to have an equipped sonar in addition to 100 nominal ASW (counting equipment stat adjustments but not improvement through [[Akashi's Improvement Arsenal]]).
