This hand-carved Boeing E-3A Sentry Wood Model Airplane in New Collector Series is a mahogany wood display model airplane, done by highly experienced craftsmen, a work of art hand-painted with great concern for details and accuracy.

The E-3 Sentry is a modified Boeing 707-320B Advanced commercial airframe. Modifications included a rotating radar dome, single-point ground, and air refueling points, and a bail-out chute.

The unpressurized dome is 30 feet (9.1 m) in diameter, six feet (1.8 m) thick at the center, and is held 14 feet (4.2 m) above the fuselage by two struts. It is tilted down six degrees to reduce drag on take-off, and while flying endurance speed (which is corrected electronically by both the radar and SSR antenna phase shifters). The dome uses both bleed-air and cooling doors to maintain ambient temperature. The hydraulically rotated antenna system permits the Westinghouse AN/APY-1 and later Hughes Aircraft AN/APY-2 passive electronically scanned array radar system to provide surveillance from the Earth's surface up into the stratosphere, over land or water.

Other major subsystems in the E-3 are navigation, communications and computers (data processing). Consoles display computer-processed data in graphic and tabular format on video screens. Console operators perform surveillance, identification, weapons control, battle management and communications functions.
