Sensor probes would basically be tiny satellites that would extend the users sensor range. These probes would be built in special probe factories. The probes would be the size of mines and could be carried by one crew member. They would be launched individually from a utility launcher . A few seconds after deployment the probe would deploy solar panels and act like a sensor. These could be used to spy on enemies or to monitor areas of space.
Been suggested before mate
Maybe there could be some sort of "spy probe" or "intelligence probe" that would be used to spy on enemies. This probe would turn invisible after deployment. The cloak would be lost and the probe destroyed if it was hit by a weapon.
