In the light of growing Chinese incursions into Japanese airspace, the Japan Air Self-Defense Force has established a new permanent squadron of Northrop Grumman Hawkeye airborne early-warning aircraft on the island of Okinawa. The ministry of defense has also broken ground for a new radar site on Japan’s westernmost island, Yonaguni.
Japan–United States relations
Faced with China’s increasingly assertive military posture, as well as a continuing ballistic missile threat from North Korea, Japan plans to spend more on defense, boosting its air and maritime forces. The plan commits to buying 28 Lockheed Martin F-35 Lightning II combat aircraft, 17 Bell-Boeing MV-22 Osprey tiltrotors, and three Northrop Grumman Global Hawk UAVs over the next five years. The Japan Air Self-Defense Force (JASDF) will also upgrade existing fleets of F-2 and F-15 fighters.
