E-3 AWACS OVERVIEW

The E-3 Airborne Warning and Control System (AWACS) represents the world's standard for airborne early warning systems.

E-3 fills the needs of both airborne surveillance and command and control (C2) functions for tactical and air defense forces. It provides a highly mobile, survivable surveillance and C2 platform.

The E-3 offers superior surveillance capabilities. Equipped with a "look-down" radar, the AWACS can separate airborne targets from the ground and sea clutter returns that confuse other present-day radars. AWACS' radar

Its radar "eye" has a 360-degree view of the horizon, and at operating altitudes can "see" more than 320 kilometers (200 miles). It also can detect and track both air and sea targets simultaneously.

In service since 1977, AWACS has earned the reputation as an international keeper of the peace in operation with the U.S. Air Force, NATO, United Kingdom, France and Saudi Arabia.

The E-3 Role

In its tactical role, the E-3 provides quick-reaction surveillance and C2 necessary E-3 AWACS to manage both tactical and defensive fighter forces. The E-3 can detect and track hostile aircraft operating at low altitudes over all terrain, and can identify and control friendly aircraft in the same airspace. The AWACS' mobility allows rapid deployment in any military action, regardless of intensity.

In its strategic defense role, the E-3 provides the means to detect, identify, track and intercept airborne threats.

Characteristics

The basic E-3 aircraft is a militarized version of the Boeing 707-320B commercial jetliner airframe. It is distinguished by the addition of a large, rotating rotodome containing its radar Boeing 707 antenna and identification friend-or-foe (IFF) and data-link fighter-control (TADIL-C) antennas.

Its mission system includes surveillance radar, navigation, communications, data processing, identification and display equipment. The heart of the information processing network is an airborne version of the IBM command and control multiprocessing computer.

U.S. and NATO E-3s are powered by four TF-33, 21,000-pound-thrust jet engines. E-3s for Saudi Arabia, the United Kingdom and France are powered by four, higher-performance CFM-56 engines. The new engines allow operation at higher altitudes, extending the horizon for radar surveillance.
