If they can get the range of this weapon accurately out to 200 miles, then it is a game changer. At that point, it is time to bring back Battleships. Montana class with railguns instead of 16 inchers.
Even 7000fps 200 miles is quite a stretch and since the rounds are kenetic, there won’t be a lot of penetration power left. There has to be more to this than i’m seeing.
Second time have seen Montana class, there is no such thing as a Montana class battleship
Bring back Monitors—armed with rail Guns. Cheaper than A Battleship and just as deadly because they are accurate.
