The Japanese Ministry of Defense (MoD) plans to upgrade 68 Boeing-Mitsubishi F-15J Eagle fighter aircraft through the Japan Super Interceptor (JSI) programme, it confirmed on 4 February.

The MoD also said that the estimated life-cycle costs of the 68 Japan Air Self-Defense Force (JASDF) aircraft over 30 years – including the upgrade – will amount to JPY646.5 billion (USD5.6 billion).

An MoD document said the upgrade includes the integration of long-range stand-off missiles, radars that can lock multiple targets simultaneously, an increased munitions payload, and enhanced electronic warfare capability.

According to Japan's 2021 defence white paper, the JASDF operated, as of March 2021, a total of 201 single-seat F-15Js and twin-seat F-15DJs. The MoD has previously upgraded the combat capabilities of 102 of these aircraft: 68 F-15Js and 34 F-15DJs.

The remaining 99 aircraft are to be replaced by 147 Lockheed Martin F-35 fighter aircraft – 105 F-35As and 42 F-35Bs – during the coming decade.
