E-3 Sentry AWACS Aircraft

Full Specifications

E-3 Sentry AWACS Airborne Early Warning System

The E-3 Sentry AWACS aircraft remains one of the most recognizable airborne command and control platforms in modern warfare. Built around a modified commercial airframe, it provides long-range surveillance, battle management, and airspace coordination. Its defining feature is the rotating radar dome mounted above the fuselage, enabling 360-degree coverage to detect and track aircraft, missiles, and surface targets over vast distances.

Designed during the Cold War, the E-3 continues to support U.S. and allied operations, offering real-time situational awareness and command capabilities in complex, multi-domain environments.

Manufacturer

The E-3 Sentry is produced by Boeing, with its radar and mission systems developed by Northrop Grumman. Originating in the United States, the aircraft is based on the Boeing 707 platform and has undergone multiple upgrades to remain operationally relevant.

Speed and Range

The aircraft has a maximum speed of approximately 530 mph (Mach 0.8) and a range exceeding 8,000 km without refueling. With aerial refueling, endurance can extend beyond 20 hours, allowing persistent surveillance over contested regions. Its high-altitude operation enhances radar coverage, making it a key asset for early warning and airspace control.

Cost/Price

The estimated unit cost of an E-3 Sentry is around $270 million, depending on configuration and upgrades. Lifecycle costs are significantly higher due to maintenance of aging airframes and complex electronic systems.
