Hunter

Hunter-class strike craft have parasite transmitters which can be sent to a vessel to latch on. The transmitters then stick to the vessel, reporting its movements via hyperspace messaging. They can only be removed when a vessel returns to shipyard for repairs. Sending a few of these into battles can quickly provide great amounts of information on crafts' whereabouts. Wary enemy commanders will be forced to keep affected vessels away from the rest of their fleet unless they do not care if significant information about their fleet is thus leaked to enemy intelligence.
