CDR SALAMANDER: Yes, a gun on top of a gun, and more of them, is your solution. “Not that there is anything wrong with a good 30mm chain gun. Those will fit in places where 50 mm and larger guns just can’t squeeze in. We also love ‘ole Ma-Deuce. In the military version of a Turducken, what if we mounted a .50 cal on top of a 30mm?”
When the war starts, we always wind up adding guns to our ships that they should have had already. Especially antiaircraft guns. Which this time around will probably be antidrone guns.
