The Boeing E-767 is an Airborne Warning and Control System (AWACS) aircraft that was designed in response to the Japan Air Self-Defense Force's requirements.

On September 6, 1976, Soviet Air Forces pilot Viktor Belenko successfully defected to the West, flying his MiG-25 'Foxbat' to Hakodate, Japan.

[2] The E-2C was put into service with the Airborne Early Warning Group (AEWG) at JASDF Misawa Air Base in January 1987.

In addition, Japanese aerospace companies are responsible for 15% of the airframe production for the 767, meaning some of the money would indirectly return to Japan.

In the second stage, the aircraft were modified to carry AWACS equipment by the US and Japanese contractors, supervised by the U.S. government under Foreign Military Sales rules.

[4] The mission electronics equipment are installed in forward cabin to balance the weight with the rotodome mounted above the aft fuselage.

The E-767 is powered by two General Electric CF6-80C2B6FA high bypass turbofan engines, generating 273.6 kN (61,500 pounds) thrust each.

The Foreign Military Sale was contracted through the Electronic Systems Center at Hanscom Air Force Base, Massachusetts.

RSIP increases the AWACS aircraft's radar sensitivity, allowing it to detect and track smaller targets.

It also improves the radar's existing computer with a new high-reliability multi-processor and rewrites the software to facilitate future maintenance and enhancements.

On May 10, 2000, all four E-767s were put into service with Airborne Early Warning Group (AEWG) 601st Squadron at JASDF Hamamatsu Air Base.
