Ship types in DarkSpace are equivalent to classes in role-playing games. Scouts are more for players interested in speed and subterfuge. Stealth craft also attract fans of underhanded tactics. Interceptors provide defense for heavy battle cruisers. Engineering ships can set up defense platforms or sensor stations to supplement player controlled orbital battle platforms.
Bombers weaken planetary defenses so that transport ships can move in with ground troops.
As a result you're not actually going to be aiming or firing any of the weapons yourself. Real captains don't bother with that crap. While these guys are carrying out your orders you can move on to other more pressing considerations. Being a ship captain means letting subordinates carry out your orders. You can't do it all yourself.
