This is the Military Missile, an enhanced hardened missile.
Faster, more accurate, and costlier than the "hardhead", when ECM'd the mil missile seeks out priority targets, namely Thargoid warships and known pirate vessels.
If it fails to find priority targets in the vacinity, then it defaults to standard hardhead behaviour, self-destructing or chasing down it's origional target.

Countermeasures: ECM, AMS, fleeing on injectors.
