The
Boeing E-3 Sentry, commonly known as
AWACS, is an
airborne early warning and control (AEW&C) aircraft developed by
Boeing as the prime contractor. Derived from the
Boeing 707, it provides all-weather surveillance, command, control, and communications, and is used by the
United States Air Force,
NATO,
Royal Air Force,
French Air Force, and
Royal Saudi Air Force. The E-3 is distinguished by the distinctive rotating radar dome above the fuselage. Production ended in 1992 after 68 aircraft had been built.
