The E-3 Sentry Airborne Warning and Control System (AWACS) serves as a critical force multiplier for US military operations worldwide.

It provides commanders with real-time situational awareness, command, and control for air operations.

The aircraft has been in US air defense since 1977. Built on a modified Boeing 707 airframe, it is equipped with a distinctive large radar dome.

The dome measures 30 feet (9.1 meters) in diameter and six feet (1.8 meters) thick. It sits 11 feet (3.33 meters) above the fuselage on two struts.

The radar enables surveillance from Earth's surface up into the stratosphere.It works over land or water with a range exceeding 250 miles (375.5km).

The system can detect and track low-flying airborne targets.

Onboard computer subsystems gather broad battlefield information. This includes position and tracking data on friendly and enemy aircraft and ships.

This intelligence can be transmitted to command centers, ships, or senior leadership in real time.

AWACS extends the radar coverage of US Army Patriot missile systems and Air Force fighter jets. These platforms have more limited radar ranges on their own.

By sharing long-range radar data, the Sentry helps other systems "see" farther. This improves early warning and response capabilities.

Battlefield coordination

The E-3 excels in rapidly changing combat environments.

It serves as a flying command center that can adjust radar positioning to cover evolving battlefields and coordinate operations from hasty or austere airfields.

AWACS strengthens coordination across military branches and partner nations.

It uses Link 16 communications to connect ships, aircraft, and ground stations across the battlespace.

The Sentry can serve as air traffic control, direct friendly fighters, assist Carrier Strike Groups in launching aircraft, and coordinate search and rescue operations using helicopters.

It also communicates with land-based air defense systems to identify friend or foe in real time during combat operations.

The E-3 Sentry has proven it can respond quickly to crises worldwide. It supports military operations across different theaters and environments.

Deployed globally, including in NATO missions, AWACS provides critical air command and control wherever needed.

This is especially valuable in fast-moving or remote environments where traditional ground-based systems cannot reach.
