Introduction
呉海軍工廠砲熕部が極秘開発した世界最大最強級の戦艦主砲、その改良改修型です。
敵主力戦艦に対してアウトレンジが可能な「大和」型戦艦搭載用主砲を、各種戦訓を採り入れて改修強化しました。
「大和」「武蔵」への装備、さらに「15.5cm三連装副砲改」との複合装備によって、本兵装はその真価を発揮します。
An improved variant of the largest and most powerful ship guns ever built, which were developed in secret at Kure Naval Yard Gunnery Division.
This strengthening and improvement incorporate the various lessons learned from the main batteries installed on the Yamato-class battleships, which could outrange the enemy's main battleships. The true value of this weapon shines when equipped together with the 15.5cm Triple Gun Mount Kai (Secondary) aboard the Yamato and Musashi.
