Japan is now set to procure forty-two F-35A Joint Strike Fighters, with the first four aircraft ordered just last month. It is continuing development of the indigenous F-3 fighter project to replace the F-15, under the assumption that future first-line American fighters will be off limits. Meanwhile, F-15J and F-2 fighters are receiving upgrades to boost their air-to-air capability.
To provide early-warning capabilities, as well as command and control, Japan has a fleet of America-sourced aircraft. Japan has four E-767 airborne warning and control system aircraft, and thirteen E-2C Hawkeye airborne early-warning aircraft. The JASDF is set to acquire the latest E-2D Hawkeyes to help deal with the growing number of air intercepts.
