The AN/APG-78 “Longbow” is a short range, operating in Ka-Band millimeter-wave multimode surveillance and fire-control radar and target acquisition system.
The AN/APG-78 and a radar frequency interferometer are housed in a dome located above the main rotor. The radome's raised position enables target detection while the helicopter is behind obstacles (e.g. terrain, trees or buildings). The AN/APG-78 is capable of simultaneously tracking up to 128 targets and engaging up to 16 at once, an attack can be initiated within 30 seconds. A radio modem integrated with the sensor suite allows data to be shared with ground units and other Apaches; allowing them to fire on targets detected by a single helicopter.
The radar is fielded with the Apache AH-64 Attack Helicopter system in the US Army.
