Defensive AA Fire Data

Revision as of 21:05, 21 July 2018

The most vital consumable against aircraft. It temporarily increases the damage of anti-aircraft guns as well as decreases the accuracy of enemy bombers. This means whatever target these bombers are attempting to hit will take significantly less damage. This consumable is available only on non-British cruisers from Tier VI and up and aircraft carriers from Tier VIII and up. Some late-hull American destroyers can also equip it in exchange for their Engine Boost  consumable. Cruisers equipped with Defensive AA Fire should always be escorting friendly ships when the threat of an air strike is present.

For aircraft carriers, this consumable lasts much longer but has fewer uses and a much longer cooldown. It is essential to prevent early sniping by an enemy aircraft carrier. While active, the effectiveness of the carriers' AA guns are increased by a factor of 1.25 for American carriers, and 1.75 for Japanese carriers. Unlike cruisers, this consumable does not affect all the AA guns on an aircraft carrier - only the 40mm AA guns will receive the benefit, with the exception of Shokaku (her 25mm AA guns receive the benefit instead, since she is not equipped with 40mm AA guns).

Note: Cruisers (other than British and Italian cruisers) can exchange this consumable for Hydroacoustic Search . Italian cruisers can mount both Defensive AA Fire and Hydroacoustic Search at the same time.
