The application of advanced avionics software in the F/A-22 is key to the Raptor's revolutionary performance advantage over any other fighter. In the air-to-air arena, the stealthy F/A-22 will be virtually unseen on radar, while its sophisticated array of sensors and advanced radar will allow it to reach out and strike adversary aircraft undetected from long range. The advanced software package will also enhance the Raptor's ability to deliver precision air-to-surface weapons on target, day or night, in any weather. [U.S. Air Force photo]
