In an air-to-air role, the JHMCS (Joint Helmet Mounted Cueing System), combined with the AIM-9X missile, form the High-Off-BoreSight (HOBS) system. HOBS is an airborne weapon-interception system that enables pilots to accurately direct, or "cue," onboard weapons against enemy aircraft merely by pointing their heads at the targets to guide the weapons, while performing high-g aircraft maneuvers that may be required to complete the attack. In an air-to-ground role, the JHMCS is used in conjunction with targeting sensors (radar, FLIR, etc.) and "smart weapons" to accurately and precisely attack surface targets. In all roles, the JHMCS provides the pilot with aircraft performance, targeting, weaponry and threat warning information, regardless of where the pilot is looking, significantly enhancing pilot situation awareness throughout the mission. In a dual-seat aircraft, each crewmember can wear a JHMCS helmet, perform operations independent of each other, and have continuous awareness of where the other crewmember is looking.
