The simulation uses 18.1-inch guns to separate a ballistic maximum at roughly 45 degrees from the shorter range available when the mount can elevate only to 30 degrees. A gun's calibre and theoretical maximum do not describe the range available under the game's firing solution. The permitted elevation sets the practical limit in this trial. The displayed range therefore reflects a 30-degree constraint, while the historical gun could reach farther at 45 degrees.

Gun elevation changes Yamato's practical range
A Yamato-style design shows why theoretical gun range and the range available at a ship's permitted elevation are not the same thing.
