The Boeing E-3 Sentry, commonly known as AWACS, is an American airborne early warning and control (AEW&C) aircraft developed by Boeing.

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 (ROTODOME) above the fuselage.
Production ended in 1992 after 68 aircraft had been built.

In the mid-1960s, the US Air Force (USAF) was seeking an aircraft to replace its piston-engined Lockheed EC-121 Warning Star, which had been in service for over a decade.

After issuing preliminary development contracts to three companies, the USAF picked Boeing to construct two airframes to test Westinghouse Electric and Hughes’s competing radars.
Both radars used pulse-Doppler technology, with Westinghouse’s design emerging as the contract winner.
Testing on the first production E-3 began in October 1975.
