Japan Looks to E-2D Hawkeye for Early Warning and Surveillance

June 4, 2019
Japan received its first delivery of an E-2D Advanced Hawkeye from Northrop Grumman earlier this year, which provides enhanced security and surveillance capabilities.

Japan has operated Northrop Grumman E-2C Hawkeye aircraft since 1983 and is the largest operator of such aircraft in the world outside of the United States. As a step up, the nation accepted the first E-2D Hawkeye aircraft from Northrop Grumman earlier this year as part of efforts to meet the needs for next-generation airborne early-warning systems.

As Jane Bishop, vice-president and integrated product team leader for manned airborne surveillance programs for Northrop Grumman, explained, “Northrop Grumman’s longstanding partnership with Japan is beginning a new chapter with the delivery of the first Japan E-2D. This aircraft provides a significant increase in early warning and surveillance capability to outpace Japan’s evolving security needs.”

Compared to the E-2C, the Northrop Grumman E-2D Hawkeye (see figure) provides a significant advance in radar technology, making it possible for the aircraft to track threats at extended ranges. The E-2D offers interoperability with next-generation aircraft systems and U.S. Navy allies to support regional security cooperation. To ensure long-term success of the Japan E-2D fleet, Northrop Grumman is providing continued support to JASDF in the areas of sustainment and maintenance, in coordination with several Japanese firms.
