Introduction

高角砲の対空射撃用の高射装置です。
高射機と高射射撃盤を組み合わせ、高角砲の有効な対空射撃をサポートします。
やや、旧式ではありますが、主力の戦艦や巡洋艦などに搭載されました。

This is the high-angle guns' director.
The director and its firing dish together locate a target and find its best-fit firing angle.
...somewhat. This one is obsolete, and its primary function is already built-in on battleships, cruisers, etc.

Anti-Aircraft Fire Directors (AAFD) are quipable in RE.

They provide a good Anti-Air boost, and are required to trigger some AACI.
They are notably used to provide AA and accuracy when improved .

Trivia

Note: while not directly referenced by name, the formal definition of the director is an fire-control system (FCS) (火器管制装置). Slightly different from radar in that the FCS/director finds a possible point in which the bullet will arrive at. As demonstrated on wikiwiki:
> Radar: "The enemy is over here!~ Here is contact!~"
> FCS: "Um, the enemy has exposed themselves, so I think this shot angle is good!~"
