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 is maturing to a point where sustainment issues, often overlooked in development, are becoming critical and widely reported, exacerbated by a damning Government Accountability Office report.
The F-35 is a cornerstone of modern Western air power, making its low readiness a major strategic vulnerability and a critical indicator of broader issues within the defence industrial base.
The awareness of systemic sustainment issues fundamentally shifts the conversation from F-35 procurement to its long-term operational viability, potentially forcing significant policy and investment changes for sustainment over new production.
- · Defence sustainment companies
- · Rival fighter jet programs (e.g., NGAD)
- · Software and AI solutions for maintenance logistics
- · F-35 program office
- · Lockheed Martin (if sustainment contracts are not secured/improved)
- · US and allied air forces
The F-35 fleet's low mission capability directly reduces operational readiness for key strategic defence objectives.
Increased pressure to divert procurement funds towards sustainment and modernization of existing aircraft, impacting future defence spending priorities.
Allies reliant on F-35 capabilities may seek alternative defence partnerships or accelerated development of indigenous solutions, leading to shifts in geopolitical alliances and defence industrial strategies.
