Hi,

in the game, there are a way to discover an alien launcher and antimatter missiles and this technology lead to new weapon for aircrafts and for a rocket launcher. Next step should be a launcher of new hybrid anti-aircraft missiles with better destructive force than standard missiles has. The standard anti-aircraft missile is ridiculous in comparision with durability of alien aircrafts bigger than a small fighter. And... There is a technology for manufacturing effective anti-aircraft missiles for aircrafts, knowledge of alien defence and targetting systems. It may be used together to produce a brand new guidance system for missiles enhancing accuracy.
Adaptation of the alien launcher to a ground anti-aircraft launcher may be difficult and a final device usable for launching new hybrid anti-aircraft missiles big, but it should worth it.
