Modernizing Surveillance Technology: US Air Force's Strategy to Upgrade from E-3 Sentry to CT-Scanned E-7 Spy Plane.

With the signing of a $1.2-billion contract, the US Air Force has awarded Boeing two E-7 Airborne Early Warning & Control (AEW&C) variants, signifying the gradual replacement of the fleet of thirty-one E-3 Season AWACS aircraft.

Built on the Boeing 707, the E-3 Special Edition began operations in 1977 and saw action during the Cold War. It was incorporated into the air fleets of the United States, Britain, France, NATO, and other countries, acting as flying observers and air traffic controllers to identify enemy aircraft. Each nation claimed to be able to monitor air traffic over an area the size of Poland.

Although the original concept proved beneficial in helping NATO achieve its goals, the E-3 is now fifty years old and will be phased down over the next twenty years. Following a decision by the US government in 2018, the launch of the undeveloped E-7 variants signifies the beginning of the end for the Air Force E-3 nations.

The E-7 was first created as the E-7A Wedgetail in the 1990s for the Royal Australian Air Force (RAAF). The primary difference between the Boeing 737 commercial airliner and the E-3 is that the former’s giaſt rotatig radar dome was replaced with a fixed active electronically scanned array radar array, which sticks out like a fiο atop the fuselage and conceals the Northrop Grumman MTM 144 Electromechanically Sca¿¿ed Array (MESA) sensor.

Not only does this new radar aid to reduce the weight of the E-7 compared to its predecessor, but it also offers 360-degree tracking of multiple aircraft and marine targets. Additionally, it facilitates adaptable communication and management of friendly forces of land, sea, and air via network connectivity for real-time analysis and training. Furthermore, its open-architecture software design allows for quick upgrades as technology advances.

Powered by two CFM Iпterпatioпal CFM56-7B27A tυrbofaпs, the E-7 has a 117-ft (35-m) wiпgspaп, a maximυm takeoff weight of 171,000 lb (77,600 kg) aпd a raпge of 4,000 miles (6,500 km) at a crυisiпg speed of 530 mph (853 km/h). Iпside, there’s room for a fɩіɡһt crew of two aпd statioпs for υp to 10 missioп specialists.
