military-aircraft-e-3

The E-3 is a costly machine, yet as an airborne warning and control system it is a very cost effective "force multiplier". First flown in the EC-137D prototype, the Westinghouse APY-1 s surveillance radar is mounted with its antenna in the large rotor dome above the rear fuselage to search to a radius of 250 miles. The airframe is based on the model 707-320B civil transport, and the first of 24 core E-3A Sentries entered service in March 1977. The next 10 aircraft were completed as standard E-3A Sentries, as were NATO's aircraft. Older aircraft have been upgraded, and the operators can monitor all air activities within radar range and control the efforts of friendly air units. In-flight refueling capability boosts endurance most use fully
