The no.3 twin gun is an upgraded version of the 20.3cm 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 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.
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).
- Most main guns come with "Hidden Fit Bonuses/Penalties", especially larger ones.
