U.S Air Capabilities The debate around the F-15EX and the F-35

Abstract

This study aims to analyze the prospects of the F-15EX as a military modernization and procurement program. Since it consumes a relatively large portion of the Air Force budget, competing with other programs such as the F-35, this study proposes a comparative analysis between the two. For this, it draws on bureaucratic politics theory, defense economics, and neorealism concepts. This fundamentally descriptive and exploratory study primarily relies on recent data and official documents. The capabilities of the F-15EX are inferior to those of the F-35 despite its higher payload capacity and the ability to carry heavier supersonic weapons. The programs stand in direct budgetary competition. Is it worth investing in the F-15EX while other programs are also vying for the limited resources of the Air Force? Answering this question requires comparing the capabilities, complementarities, costs, and the true need for the program Although some argue that the F-15EX offers advantages regarding payload and specific mission profiles, this study contends that the program should receive none of its current budgetary priority. In an international system characterized by the relative distribution of power and resources, should the United States prioritize other objectives—such as the full production and deployment of the F-35, along with the development of the B-21 Spirit and the Sixth-Generation Fighter? The threat environment is evolving rapidly in the Pacific theater and in Europe.
