The F-35 is the most expensive weapons program in human history at $1.7 trillion over its lifetime. It is also the lens through which every modern defense procurement story must be understood — cost overruns, contractor lock-in, and the politics of keeping the program alive.

In a typical competitive market, price and efficiency drive the sale. In defense, governments often deal with 'sole-source' contracts. This means the government enters a long-term agreement with a single manufacturer, such as Lockheed Martin for the F-35, because there are few other companies capable of building such complex technology. Once a project begins, 'contractor lock-in' can occur—a situation where the government becomes so reliant on a specific company’s expertise and infrastructure that switching providers becomes prohibitively expensive or technically impossible, even if costs continue to rise.
These occur when a project costs more than initially budgeted. The F-35 program faced various technical hurdles, design adjustments, and software integration complexities that pushed development timelines further out and budgets higher. Because these projects are funded by taxpayer dollars, transparency is vital. However, the sheer scale of the F-35 makes it difficult for the average citizen to track where every dollar goes. When a program is declared 'too big to fail,' it often continues to receive funding despite delays, creating a cycle of escalating investment.
The F-35 program has components manufactured in almost every state in the U.S. By spreading production across many congressional districts, contractors ensure that members of Congress have a vested interest in the program’s survival. If a representative’s constituents are employed at a factory that builds wings or landing gear for the fighter jet, that representative is far less likely to vote to cut funding for the program, regardless of its performance or cost issues. This makes defense spending as much a local economic issue as it is a national security one.
It illustrates how long-term military commitments can dominate federal budgets, leaving less room for other public investments. For citizens and taxpayers, the lesson is clear: understanding how procurement works is essential to understanding the national budget. As technology evolves and warfare shifts toward cyber and autonomous systems, the government will face the same dilemmas again—balancing the need for advanced national security capabilities with the responsible management of public resources.
