Boeing E 3A Sentry AWACS Airborne Radar Aircraft

The Boeing E 3A Sentry is one of the most recognizable airborne early warning and command aircraft ever built. Known globally as AWACS, it serves as an airborne command post, radar sensor, and battle manager. Its rotating radar dome and long endurance allow commanders to see far beyond ground based sensors, track hundreds of targets, and direct air operations in real time. For the United States and its allies, the E 3A remains a core element of air dominance.

Manufacturer

The E 3A Sentry is manufactured by Boeing Defense, Space and Security. It is based on the Boeing 707 commercial airframe and was developed during the Cold War to counter large scale air threats. The aircraft entered US Air Force service in the late 1970s and was later adopted by NATO and several allied air forces.

Speed and Range

Powered by four turbofan engines, the E 3A cruises at high subsonic speed and can remain on station for extended periods. With aerial refueling, missions can last well beyond ten hours. Its AN APY radar can detect and track aircraft and surface targets at ranges exceeding 400 kilometers, depending on conditions and target size.

Cost / Price

The original unit cost of the E 3A was approximately 270 million USD in historical dollars. Modern sustainment costs are high due to age, fuel consumption, and maintenance demands. Despite this, the aircraft continues to deliver strong operational value until replacement platforms fully mature.
