The raised position of the radome enables the detection of targets and launching of missiles while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The AN/APG-78 is capable of simultaneously tracking 128 targets and engaging the 16 most dangerous ones, and can initiate an attack within 30 seconds, while passing data on the other targets to other Longbow Apaches via data link. The data link is housed in a radio modem integrated with the sensor suite allows data to be shared with ground units and other D-models; allowing them to fire on targets detected by a single helicopter.
