One big issue I have with missile launchers:  They all shoot at the same thing.   

I have a massive ship teaming with missile launchers.  I get attacked by 20 tiny ships.   The big ship will attack the little ships in order.  

Switch to the real world.  The Apache can attack 16 different targets at the same time while tracking 128.  

These are missiles, fire and forget has been a mainstay of them for decades now. 

Even WWII didn't have to just shoot at one ship until it was destroyed.  Just about all of them could attack two targets with its big guns.  Though far less effective, each turret could operate with out fire control and attack a ship for every target.
