The F-35 Joint Strike Fighter, known as the cornerstone of modern US airpower, has reached a significant milestone with its entry into full-rate production as of March 2024.
However, a recent Government Accountability Office (GAO) report released on May 16, 2024, highlights that the program continues to grapple with severe production delays and modernization issues that could affect its operational readiness and cost efficiency.
Full-Rate Production Achievement
Persistent challenges overshadow this achievement despite the F-35 program declaring full-rate production—a phase indicating satisfactory performance and reliability.
The program’s transition was marked by the completion of its testing simulator and the execution of final simulated tests designed to ensure the aircraft meets stringent operational requirements.
Continued Delivery Delays
The GAO report underscores a troubling trend in the program: continuous delays in the delivery of engines and aircraft.
In 2023, 100 percent of the engines supplied by Pratt & Whitney and 91 percent of the aircraft from Lockheed Martin were delivered later than scheduled.
These delays have been attributed to an amalgamation of manufacturing hiccups and parts shortages, which have worsened over recent years.

Modernization Stalls
As the Department of Defense (DoD) embarks on a comprehensive hardware and software modernization initiative known as Block 4, the F-35 faces another set of hurdles.
The program struggles to modernize its thermal management subsystems, which are essential for cooling the aircraft.
The GAO points out that the efforts to upgrade these systems are fraught with risks stemming from undefined requirements, immature technologies, and fluctuating cost estimates.
This has resulted in delays and potential cost overruns, jeopardizing the program’s long-term success.
Financial Implications
The financial stakes are high, with the DoD estimating that the costs to maintain and operate the planned 2,470 aircraft through 2088 will surpass $2 trillion.
This projection underscores the critical need for stringent management and oversight to prevent further escalations in costs, which could significantly burden taxpayers.
GAO’s Recommendations
Since 2001, the GAO has consistently reviewed the F-35 program, offering 54 recommendations to enhance its efficiency and effectiveness.
In May 2023, seven recommendations were specifically aimed at improving the Block 4 cost reporting and the program’s broader modernization efforts.
While some recommendations have been addressed, the report notes that many are yet to be fully implemented by the DoD, highlighting a gap in the adherence to oversight guidelines.
Congressional Oversight
Given these ongoing challenges, Congress has mandated statutory provisions for GAO to regularly review the F-35 program.
These provisions aim to ensure transparency and accountability in how the program is managed and evolved, providing lawmakers with the insights needed to make informed decisions about future funding and strategic direction.
Looking Forward
As the F-35 program continues to face these multifaceted challenges, the focus must now shift toward comprehensive solutions that address both immediate and long-term issues.
Effective management, timely implementation of recommended changes, and a clear strategic vision are essential to ensure that the F-35 can meet the future needs of the US military and maintain its edge in global airpower.
The coming years will be critical in determining whether the F-35 can overcome its current hurdles and fulfill its promise as a cornerstone of US military aviation, or if it will remain mired in delays and cost overruns that could compromise its potential.
With strategic adjustments and diligent oversight, there is hope that the program can navigate these turbulent waters and emerge stronger.
