F-35 program chief warns fleet has outgrown its support system amid record-low readiness

The hearing comes on the heels of a Government Accountability Office report this month that found just one in four F-35s were fully mission capable.
The F-35 program has matured to a significant fleet size, and recent GAO reports are highlighting chronic and systemic readiness issues that have been building over time.
This exposes a critical gap in Western military readiness, particularly concerning a flagship defense asset, impacting global power projection and alliance capabilities.
The focus will shift from F-35 production numbers to sustainment and support infrastructure, potentially diverting resources and introducing new strategic defense priorities.
- · Defense logistics and sustainment companies
- · Competitors to the F-35 program (e.g., other fighter jets, drone programs)
- · Governments investing in diversified defense platforms
- · Lockheed Martin (F-35 prime contractor)
- · Air forces heavily reliant on the F-35
- · Defense budgets without adequate sustainment allocation
Increased scrutiny and funding allocation towards F-35 logistics and maintenance will become paramount.
Nations may reassess their F-35 acquisition plans or explore alternative fighter capabilities and drone integration.
This could accelerate the broader adoption of defense-tech recapitalization, moving towards more modular, software-defined, and autonomously supported systems.
