Helmet-mounted display

（重定向自JHMCS）

Scorpion HMCS mounted on a HGU-55/P helmet with a clear visor

A helmet-mounted display (HMD) is a device used in some modern aircraft, especially combat aircraft. HMDs project information similar to that of head-up displays (HUD) on an aircrew’s visor or reticle, thereby allowing them to obtain situation awareness and/or cue weapons systems to the direction his head is pointing. Applications which allow cuing of weapon systems are referred to as helmet-mounted sight and display (HMSD) or helmet-mounted sights (HMS). These devices were created first by South Africa, then the Soviet Union and followed by the United States.
