English: An E-3D Sentry aircraft and crew conducting a training mission over northern England on the 15th of December 2010.

The E-3D Sentry aircraft are operated by No8 Sqn of the RAF (Royal Air Force) in the airborne surveillance and command-and-control role. Whilst 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 seperate, 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. This mission allowed vital training to be conducted, keeping the crew operationally ready.
