Introduction

初期の実用艦載電探、その改良型です。
対空用ですが、対水上電探としても使用可能です。
小型艦艇では小型でとりまわしの良い13号電探が普及していきましたが、本装備は航空巡洋艦「最上」や秋月型などに搭載運用された21号電探、そのif熟成改良型です。

An improved version of an early ship-borne radar.
Although it was designed for anti-air, it can also be used as a surface radar.
Though the smaller and easier to handle Type 13 RADAR was more widely used amongst small ships, the Type 21 RADAR was installed on the aviation cruiser "Mogami" and the Akizuki-class, with this model being a what-if upgrade of that RADAR.
