Changes

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 incorporates 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.
