The U.S. Air Force has selected Rockwell Collins for the Engineering, Manufacturing and Development (EMD) phase of the KC-135 Block 45 cockpit upgrade program, under which the company will add the next-generation autopilot, flight director, radar altimeter and electronic engine instrument display to the flight deck. Two prototype aircraft will be modified during the EMD phase to establish the production baseline for 415 additional KC-135 aircraft expected to receive the Block 45 upgrade, Rockwell Collins said. In addition, Rockwell Collins is upgrading the aircraft’s Communication/Navigation/Surveillance and Air Traffic Management (CNS/ATM). Rockwell Collins has modified and delivered more than 300 GATM equipped KC-135 aircraft to date.
