The E-3D Sentry is built by Boeing and is based on the extremely successful 707 airliner. It has been extensively modified to equip it for the AEW role by the addition of a long range surveillance radar, which is housed in the black radome on top of the aircraft, a suite of modern secure communications systems including digital data links, electronic support measures (ESM) equipment and comprehensive IFF identification systems. The engines have been changed to more powerful CFM-56s and a refuelling probe has been added so that the E-3D is capable of air-to-air refuelling from any NATO tanker.
