E-3 Sentry

An E-3 Airborne Warning and Control System aircraft from Tinker Air Force Base, Okla., flies a mission. The E-3 Sentry is modified Boeing 707/320 commercial airframe with a rotating radar dome. The dome is 30 feet in diameter, 6 feet thick and is held 11 feet above the fuselage by two struts. It contains a radar subsystem that permits surveillance from the Earth's surface up into the stratosphere, over land or water. The radar has a range of more than 200 miles for low-flying targets and farther for aerospace vehicles flying at medium to high altitudes. (U.S. Air Force photo by Tech. Sgt. John K. McDowell)
