The State Department has made a determination approving a possible Foreign Military Sale to Japan for E-2D Advanced Hawkeye Airborne Early Warning and Control Aircraft and associated equipment, parts and logistical support for an estimated cost of $1.7 billion. The Defense Security Cooperation Agency (DSCA) delivered the required certification notifying Congress of this possible sale on Jun 1, 2015.

The Government of Japan has requested a possible sale of:
- four (4) Northrop Grumman E-2D Advanced Hawkeye (AHE) Airborne Early Warning and Control (AEW&C) aircraft;
- ten (10) Rolls-Royce T56-A-427A engines (8 installed and 2 spares);
- eight (8) Multifunction Information Distribution System Low Volume Terminals (MIDS-LVT);
- four (4) Lockheed Martin APY-9 Radars;
- modifications;
- spare and repair parts;
- support equipment;
- publications and technical documentation;
- personnel training and training equipment;
- ferry services;
- aerial refueling support;
- S. Government and contractor logistics;
- engineering and technical support services;
- other related elements of logistics and program support.
The estimated cost is $1.7 billion.

This proposed sale will contribute to the foreign policy and national security of the United States. Japan is one of the major political and economic powers in East Asia and the Western Pacific and a key partner of the United States in ensuring peace and stability in that region. It is vital to the U.S. national interest to assist Japan in developing and maintaining a strong and ready self-defense capability. This proposed sale is consistent with U.S. foreign policy and national security objectives and the 1960 Treaty of Mutual Cooperation and Security.
The proposed sale of E-2D AHE aircraft will improve Japan’s ability to effectively provide homeland defense utilizing an AEW&C capability. 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. Japan will have no difficulty absorbing these aircraft into its armed forces.
The proposed sale of these aircraft and support will not alter the basic military balance in the Pacific region.
The principal contractor will be Northrop Grumman Corporation Aerospace Systems in Melbourne, Florida. The acquisition and integration of all systems will be managed by the U.S. Navy’s Naval Air Systems Command (NAVAIR). There are no known offset agreements proposed in connection with this potential sale.
