Sky Mine
this form of explosive weapon was developed during the last decades of the Old Republic. Sky mines were deployed in orbit by a delivery ship, then activated. They were given rough targetting parameters, often with transponder code masks, and then hunted down their targets. They had excellent maneuverability, and chased after their target until they ran out of fuel or were destroyed. Since sky mines were mobile, and could lock onto a target of their own volition, starfighter squadrons had to have their missions coordinated with the parameters used to program the mines.
