My ship is ready to support your rebellion, Comr4de.
A heavy-powered missile frigate with relatively high maneuverability and three missile silos. ~13-second recharge time for each silo. So thats about 1 missile every 4 seconds.
I know, it's kind of ugly, but it's supposed to be as light as possible so it can avoid incoming missiles itself. High-efficiency design.
Keep in mind this is for killing capital ships and planetary bombardments or of stationary targets, and though the missiles are very fast they cannot hit tiny targets.
