The helmet-mounted Cueing System Joint (JHMCS) is a modification of the HGU-55 / P helmet that features a display screen, projected Heads-Up (HUD) to weapons and sensors to the target signal. This system improves the effectiveness of new pre-listening, both in-air and air-ground missions. In combat, a pilot must align the aircraft to shoot at a target. JHMCS allows the pilot to see just a target to shoot. This system projects visual targeting and performance information for aircraft in the back of the helmet visor, which allows the pilot to control this information without interrupting his field of vision through the cockpit. The system uses a magnetic transmitter fixed to the pilot's seat and a magnetic field probe mounted on the helmet to define helmet pointing positioning. A Helmet Vehicle Interface (HVI) interacts with the aircraft system bus to provide signal generation for the helmet display. This provides a significant improvement for the guidance and commitment of combat.
The system will be used in JHMCS FA-18C/D/E/F, F-15C / D, F-22 and F-16 Block 40/50, with a design that is 95 percent common to the four platforms. When used in conjunction with AIM-9X missile, an effective pilot can designate and kill targets in a cone of more than 80 degrees either side of the nose of the aircraft or high out of sight (HOB).
A joint mission needs JHMCS Declaration was signed in January 1994 with a decision to enter Milestone II EMD in December 1996. An evaluation of Navy Operations (OA) was launched in August 1999 and was completed in February 2000, resulting in the initial low rate production (LRIP) approval in May 2000. A joint OA signed in August 2000 and a decision support LRIP-2 on May 01. A-3 LRIP decision is scheduled for April 2002 after completion of initial operational test and evaluation (IOT & E) with a production decision on the rating for August 2002. The system is scheduled to reach IOC for the F/A-18E/F and F-15C in FY03, the F-16 for FY04.
