The evolution of night vision equipment for aviators began with the U.S. Army in early 1982, when the Army modified its AN/PVS-5 infantry goggle to enable use by helicopter pilots. However, the infantry goggle proved to be ineffective for aviation. It later was replaced by the successful AN/AVS-6 Aviator's Night Vision Imaging System (ANVIS), which has been in production since 1985. The most widely fielded aviation night vision goggle (NVG), ITT's ANVIS saw extensive use by helicopter pilots during Operation Just Cause (1989) and Desert Storm (1991). Soon thereafter, ITT designed and introduced NVGs specifically for military pilots of fixed-wing aircraft, the move which first established ITT as the leader in aviation night vision.
Gen 3 Pinnacle" Tube Development
The story of the Pinnacle began in 1997 when the Army Night Vision Program office awarded two cost-share contracts to ITT and to Litton Electro-Optical Systems, now part of Northrop Grumman, to develop the next generation ofin image intensification devices, Gen 4 in military parlance.
