The USAF contracted Boeing, through the FMS (Foreign Military Sales) mechanism, to design and develop an integrated modernization package for Japan’s F-15J for USD 471.3 million.
Boeing’s planned modernization will be named the F-15MJ and will form the basis of the Japanese Japanese Japanese Super Interceptor, or F-15JSI, modernization program.
According to the original plans, the modernization to the F-15JSI standard will focus primarily on upgrading avionics to the latest levels. To this end, 98 F-15J will be upgraded with the AESA APG-82(v)1 radar, ADCP II advanced mission computers (according to their manufacturer, they are the most advanced in the world), new Rockwell Collins ARC-210 radios and the new Eagle Active/Passive Warning and Survivability System (EPAWSS).
This modernization program has been stalled for a couple of years due to unforeseen cost increases, and subsequent negotiations with Boeing and the U.S. Because of this issue, the F-15JSI project did not receive any funding in the 2020 and 2021 fiscal budgets. After reducing the cost of the program by removing some capabilities (e.g., the AGM-158 missile will not be integrated) and negotiated agreements, finally the FY2022 budget provided the necessary funding to modernize the Nippon Eagle.
The contract action also provides for Boeing to develop, test and deliver four weapon system trainers (simulators).
Work will be performed in St. Louis, Missouri, and is expected to be completed by Dec. 31, 2028.
