Recently, military bloggers have pointed out that the U.S. Air Force’s accelerated deployment of the F-15EX fighter jet—ostensibly to quickly replace aging fleets and counter great-power competition—actually reveals deep-seated challenges within America’s defense industrial base. Although the F-15EX is based on the 1970s-era F-15 airframe, it has been upgraded with modern avionics, radar, and weapons systems, granting it considerable combat capability. However, this ‘old platform, new tech’ approach highlights an uncomfortable reality: the F-22 production line has long been shuttered, F-35 output is constrained by cost and capacity limits, and the sixth-generation NGAD (Next Generation Air Dominance) program remains in its early development phase. Caught between technological transition, budgetary pressures, and strategic urgency, the U.S. defense industry is resorting to incremental upgrades of proven platforms. While this offers short-term readiness, it risks eroding long-term technological edge. Moreover, the F-15EX’s high unit cost—nearly matching that of the F-35 despite lacking stealth capabilities—raises concerns about its survivability in future high-end conflicts. Thus, the rush to field the F-15EX reflects not strength, but a stopgap measure amid America’s defense-industrial growing pains.
近期，有军事博主指出，美国空军加速推进F-15EX战斗机的部署，表面上是为了快速补充老旧机队、应对大国竞争，实则暴露出其军工体系深层次的困境。F-15EX虽基于上世纪70年代设计的F-15平台，但通过现代化航电、雷达和武器系统升级，具备了较强作战能力。然而，美国选择‘旧瓶装新酒’，恰恰反映出五代机F-22已停产、F-35产能与成本受限、六代机NGAD（下一代空中优势）项目仍处早期阶段的尴尬局面。军工复合体在技术迭代、预算压力与战略需求之间难以平衡，导致不得不依赖成熟平台‘打补丁’式升级。这种策略虽能短期内维持战力，却可能削弱长期技术优势。此外，F-15EX的高采购成本也引发质疑：单价接近F-35，却缺乏隐身能力，在未来高端对抗中生存性存疑。因此，F-15EX的提速并非实力彰显，而更像是美国军工在转型阵痛期的权宜之计。
