Well i went and remade the Kushan Team so you no longer have modules except for Sensor modules and Fire Control towers, however the AI no longer works. Anyways here is the break down, Fighter drive leads to Fighter Chassis which leads to Bomber and cloaked fighter research to unlock those ships. Corvette Drive unlocks repair, which leads to corvette chassis, that unlocks salvage corvettes, which leads to Heavy Corvette upgrade, Multi Gun research and mine laying tech. Frigate Drive unlocks Support frigates, leads to frigate Chassis which gives you assault Frigates, that leads to Ion cannon tech and drone tech. Now Frigate Drive also leads to Super Capital Ship drive as well as cloak gen and grav gens and gives you destroyers, leads to super capital chassis research and unlocks carriers, Missile Technology and Heavy Gun Research. Hope that helped explains how stuff now works for the kushan.
Good.
