The Boeing E-3 Sentry is an American military airborne warning and control system (AWACS) aircraft that provides all-weather surveillance, command, control and communications, to the United States, United Kingdom, France, Saudi Arabia, and NATO air defense forces. Production ended in 1992 after 68 had been built.
The E-3 as equipped in USAF and NATO service can fly without refueling for 8 hours or 4000 miles, whilst newer examples in British, French and Saudi service, equipped with CFM56-2 engines can fly for 10 hours or 5000 miles without refuelling. Its range and on-station time can be increased through inflight refueling and the use of an on-board crew rest area. The range and loiter time can be used to alter the flight plan as required for operation reasons.
