The Boeing Joint Helmet Mounted Cueing System (JHMCS) combines a magnetic head tracker with a display projected onto the pilot's visor, giving the pilot a targeting device that can be used to aim sensors and weapons wherever the pilot is looking.
With JHMCS, the pilot can aim the radar, air-to-air missiles, infrared sensors and air-to-ground weapons merely by observing the target through the helmet's visor and pressing a switch on the flight controls. Additionally, the pilot can view any desired data (airspeed, altitude, target range, etc.) while "heads-up," eliminating the need to look into the cockpit during visual air combat.
The High Off-Boresight Seeker (HOBS) consists of the new JHMCS and the new AIM-9X high off-boresight air-to-air missile.
The AIM-9X is an advanced short-range dogfight weapon that can intercept airborne targets located at high off-boresight lines-of-sight relative to the shooter, providing a weapon with a short-range intercept envelope significantly larger than any air-to-air weapon in use today.
The HOBS system (the combination of JHMCS and AIM-9X) results in a weapon that can attack and destroy nearly any airborne enemy seen by the pilot. Additionally, this weapon can be employed without maneuvering the aircraft, minimizing the time spent in the threat environment.
The JHMCS will be deployed on the F-15, F-16, F/A-18, and F-22 aircraft. The system started flight testing in late 2001. The U.S. Department of Defense awarded Boeing an $86 million contract for the first full-rate production lot of JHMCS on June 11, 2004.
