Defensive AA Fire Data

The most vital consumable against aircraft, Defensive AA Fire temporarily increases the damage of anti-aircraft guns. This means bombers are much more likely to be shot down before or after dropping their payload. This consumable is available on non-British cruisers from Tier VI and up, on upgraded hulls for American destroyers from Tier V and up, and on alternate Russian destroyer branch Tier VIII and up. Ships equipped with Defensive AA Fire should escort friendly ships when the threat of an air strike is present.

As of 0.8.0 update, aircraft carriers no longer have access to this consumable.

Most cruisers can exchange this consumable for Hydroacoustic Search . Italian and American light cruisers have access to both Defensive AA Fire and Hydroacoustic Search simultaneously. American destroyers can exchange this consumable for Engine Boost .
