Air Force wants Raytheon and Northrop Grumman to compete for a contract to upgrade the Boeing F-15E Strike Eagle radar system with an active electronically scanned array, according to Flight International. Raytheon upgraded 18 of USAF’s F-15Cs with the APG-63 and recently won a contract to upgrade Navy F/A-18E/F aircraft. Currently, USAF is considering whether to add AESA radar to Air National Guard F-15Cs to aid them in homeland defense against cruise missiles. (DR, 9/19/05)
