RAF E-3D Sentry
The RAF operates the E-3D Sentry aircraft in the airborne surveillance and command-and-control role. While primarily procured as an airborne early warning aircraft, the E-3D has been extensively employed in the Airborne Warning and Control System (AWACS) role.
The Sentry's roles include air and sea surveillance, airborne command and control, and weapons control. The aircraft's mission systems can separate, manage and display targets individually on situation displays within the aircraft, or it can transmit the information to ground-based and ship-based units using a wide variety of digital data links. The E-3D also operates as an extensive communications platform.
