The US State Department has made a determination, approving a possible sale of Northrop Grumman E-2D Advanced Hawkeye (AHE) Airborne Early Warning and Control (AEW&C) aircraft to Japan.

In an announcement on 7 March, the State Department said that the estimated USD1.381 billion Foreign Military Sales (FMS) will cover five E-2D AHE aircraft. The department added that the Japanese government had requested the purchase of the aircraft.

The State Department said that the proposed sale will improve Japan's ability to improve its “homeland” defence through the augmentation of its AEW&C capabilities. “Japan will use the E-2D AHE aircraft to provide AEW&C situational awareness of air and naval activity in the Pacific region and to augment its existing E-2C Hawkeye AEW&C fleet,” the department added.

The principal contractor for the proposed sale was identified as Northrop Grumman Corporation Aerospace Systems, Melbourne, Florida. The State Department said that “there are no known offset agreements proposed in connection with this potential sale”.

The possible sale also includes 12 Rolls-Royce (formerly Allison) T56-A-427A engines (10 installed, two as spares), six Multifunction Information Distribution System Joint Tactical Radio System Terminals, five APY-9 Radars, five AN/AYK-27 Integrated Navigation Control and Display Systems, 12 LN-251 Embedded Global Positioning Systems/inertial navigation systems with Embedded Airborne Selective Availability Anti-Spoofing Module or M-Code Receiver, and six ALQ-217 Electronic Support Measures (ESM) systems.
