Added a B turret like that of the heavy cruiser Mogami. Although the space is limited, it won't break the cannons unless you turn them too fast.

Version 1: https://www.simpleplanes.com/a/uh230P/sector-of-fire-system

A XML rotator system that limits the sector of fire of the gun mounts, which can prevent the guns from hitting themselves...most of the time. The mounts rotates to a safe direction that is closest to the indicated one. At least two mounts can fire at the indicated direction. The system can be used on warships, where most of the guns can't fire in all directions.

AG 1,2,3 for activating the guns in the four mounts.
VTOL and Trim for controlling the mounts. (Please use VTOL SLOWLY.)

The mounts are replicas of the US naval gun mount MK 38( 5-in 38-cal D.P. twin mount).<It's wrong and the correct one is https://www.simpleplanes.com/a/sia9s8/MK-38-mod-1>

The sectors:
1:225~135
2:225~135
3:90~270
