The E-3 Sentry is an airborne warning and control system, or AWACS, aircraft  with an integrated command and control battle management, or C2BM, surveillance, target detection, and tracking platform.  The aircraft provides an accurate, real-time picture of the battlespace to the Joint Air Operations Center. AWACS provides situational awareness of friendly, neutral and hostile activity, command and control of an area of responsibility, battle management of theater forces, all-altitude and all-weather surveillance of the battle space, and early warning of enemy actions during joint, allied, and coalition operations.
