IJN 15.5cm/60 Triple Mount

The IJN 15.5cm triple mount is the primary weapon of several Japanese light Cruisers, when the Mogami recieved its upgrade from these guns, the batch that were removed from it were modified and installed on the Yamato Class Battleships, as a temporary secondary armament until a dedicated turret design could be produced, due to the fact that this dedicated gun was never completed and with little to no documentation that survived the war, the Yamato-Class are now more visually recognized with these 15.5cm gun mounts instead.

3.5th Gen FT-Reload

Essentially the same as the 3.5th generation Independent Firing Sequence Reload Feature that was featured on my 38cm SK C/34 gun, but shortened to just FT Reload.

This feature is an automatically functioning system that makes for a realistic gun reloading sequence where the gun first depresses/elevates to the designated Loading Angle (7° for this one) before initiating the reload timer, upon being "loaded" the gun immediately returns to where the user originally pointed the gun.
