  • 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;

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.

E-2D Advanced Hawkeye

The E-2D Advanced Hawkeye is a game changer in how the Navy will conduct battle management command and control. By serving as the «digital quarterback» to sweep ahead of strike, manage the mission, and keep our net-centric carrier battle groups out of harms way, the E-2D Advanced Hawkeye is the key to advancing the mission, no matter what it may be. The E-2D gives the warfighter expanded battlespace awareness, especially in the area of information operations delivering battle management, theater air and missile defense, and multiple sensor fusion capabilities in an airborne system.

Hardware with system characteristics that provides:

  • Substantial target processing capacity (>3,000 reports per second)
  • Three highly automated and common operator stations
  • High-capacity, flat-panel color high-resolution displays
  • Extensive video type selection (radar and identification friend/foe)
  • HF/VHF/UHF and satellite communications systems
  • Extensive data link capabilities
  • Inertial navigational system and global positioning system navigation and in-flight alignment
  • Integrated and centralized diagnostic system
  • Glass Cockpit allows software reconfigurable flight/mission displays
  • Cockpit – 4th tactical operator
  • Open architecture ensures rapid technology upgrades and customized configuration options
The Hawkeye provides all-weather airborne early warning, airborne battle management and command and control functions for the Carrier Strike Group and Joint Force Commander
