The Boeing 757 flying testbed for the Lockheed Martin/Boeing F-22 Raptor has been delivered to Seattle, where the aircraft will be based. The Raptor will be fitted with the Northrop Grumman APG-77 phased-array radar later this year. It will also be fitted with a sensor wing on the crown of the fuselage, which will house electronic-warfare, communications, navigation and identification sensors. The wing will be installed in August 1998, with full-scale avionics testing due to begin in the fourth quarter of 1998.
