How far can it shoot accurately?
Excellent question, at sea level the atmosphere is pretty dense.
About a hundred miles.
I’m sure they are developing the new tables. Projectile tables are developed for each round developed. They actually going into such detail that they take the earth’s rotation into account which creates a slight curve in the projectiles pattern as well as the current and anticipated ship’s motion. Just using the most basic tables a battleship could place a projectile accurately over the horizon within meters. Most of the 5” and 76mm guns from the 70s on were similarly accurate though without the additonal range. I would guess - and it’s a guess- that they will be able to place it within 20meters of target on a ballistic course depending on weather. The thing is I hear they are already thinking about how to add smart guidance or mrv capability to them ... oof don’t want to be downrange of that.
