The world's first raster HUD system was developed by Marconi-Elliott Avionics in 1973 for the A-7 Corsair. The system was called TRAM (Target Recognition Attack Multisensor) and electronically combined the display of a low light level or infra-red sensor in the HUD system with the HUD symbols such that the pilot was given night vision.
Another application was to display a radar display. Symbology was added to the raster by means of a complex dual Vidicon, CRT scan converter which required a large number of preset adjustments. The HUD operated in a normal high brightness symbology mode in daylight with a raster display at night thus providing a 24 hour capability. The FLIR in the A-7 system had a zoom capability of about 11:1 and was used in identification of target ships from medium altitude.
Around 65 of these TRAM the systems were made and they saw service in Vietnam. This unit has Serial Number HXP0008 and was manufactured around 1973.
