[Commander G]

Why would SEIV need drones? You can already replace pilots and crews with computers, if you wish. If all you want is decoy missles, you could probably just add your own to the components table with the same tech requirements as Missle I. Have them do 5 damage if they actually manage to collide. Make them cheaper than missles, then you could use them to try to confuse the point defenses of your enemy. I'm not sure if the targeting system is smart enough to shoot at missles in damage order. If its, you may have to give them equivalent damage numbers and give them a very bad to hit modifier.
