As proven in Desert Storm, it is the premier air battle command and control aircraft in the world today. It contains a radar subsystem that permits surveillance from the Earth's surface up into the stratosphere, over land or water. The radar combined with an identification friend or foe subsystem can look down to detect, identify and track enemy and friendly low-flying aircraft by eliminating ground clutter returns that confuse other radar systems.
Consoles display computer-processed data in graphic and tabular format on video screens.
Console operators perform surveillance, identification, weapons control, battle management and communications functions. The radar and computer subsystems on the E-3 Sentry can gather and present broad and detailed battlefield information. Data is collected as events occur. This includes position and tracking information on enemy aircraft and ships, and location and status of friendly aircraft and naval vessels. The information can be sent to major command and control centers in rear areas or aboard ships.
