Introduction
初の実用艦載電探です。
対空用ですが、対水上電探としても使用可能です。
13号電探と混載することも可能で、基本的にこの21号は大型艦に搭載されました。
The Type 22 radar was one of the first radars to be used aboard warships. Primarily tasked as for air search, it can also be used for surface search. While this can be used in conjunction with the Type 13, the Type 21 is basically used aboard larger warships.
