Introduction

20.3cm連装砲の改良型、それが同3号連装砲です。
元々優秀な重巡洋艦用主砲をさらに改良。
55口径の極めて優れた重巡用主砲が完成しました。
優秀な砲ですが、経済性に難があり、少量の試作だけで量産はされていません。

The no.3 twin gun is an upgraded version of the 20.3 cm twin gun.
It is a further improved model of the excellent heavy cruiser main gun.
An extremely excellent heavy cruiser main gun with a length of 55[1] was made.
Although this gun is excellent, it wasn't able to be mass-produced due to economic trouble. So only a few prototypes were made.

Mechanics

Main Guns    are the main armament used by surface ships. Their main stats are the "firepower"   and "accuracy"  . They are notably required to trigger all Artillery Spotting attacks as well as some Night Cut-Ins, notably the "Double Attack" (DA).
