Airborne Warning and Control System (AWACS)

Product Name: Airborne Warning and Control System (AWACS)

Product Description

Based on a Boeing 707-320B airframe, the E-3 airborne warning and control system (AWACS) provides surveillance, command-and-control (C2), and communications functions for tactical and defensive missions. In service since 1977, it is used by the U.S. Air Force, NATO, United Kingdom, France, and Saudi Arabia.

Tactical and Defensive Mission Capabilities

The E-3 provides quick-reaction surveillance and C2 management for tactical and defensive missions.

  • Detection, identification, tracking, and interception of hostile aircraft operating at low altitudes over all terrain
  • Identification and control of friendly aircraft in the same airspace as hostile aircraft

The AWACS Mission System

The E-3 AWACS combines the following mission-system components: surveillance radar (housed in a rotating dome), navigation, communications, data processing, identification equipment, display equipment, and an airborne version of the IBM command-and-control multiprocessing computer.

  • Look-down radar elements:
    • Look-down radar antenna
    • Identification friend-or-foe (IFF) antenna
    • Data-link fighter-control (TADIL0C) antenna
  • Look-down radar capabilities:
    • 360-degree view of the horizon
    • 200-mile range at operating altitudes
    • Separation of airborne targets from ground and sea clutter signal returns that confuse other radars
    • Simultaneous detection and tracking of air and sea targets

The Boeing 707-320B Airframe

The E-3 is a militarized Boeing 707-320B commercial jetliner.
