Pentagon’s $31B Vanish Act?

A federal watchdog says the Pentagon cannot reliably account for about 26 million F-35 parts worth $31 billion, and thousands are missing from its records.

Story Snapshot

Government Accountability Office found weak controls over a $31 billion F-35 parts inventory.
More than 17,000 parts, valued around $1.3 billion, were missing from records as of March 2026.
Auditors say program offices lack clear procedures, trained staff, and reliable systems.
Earlier gaps from 2023 still left over 1 million parts worth $85 million unresolved.

GAO says oversight gaps put billions in parts at risk

The Government Accountability Office reported that the F-35 program manages about 26 million parts, worth about $31 billion, across more than 700 sites. Auditors said the Department of Defense lacks procedures to ensure accurate records and sound financial reporting for these parts. The F-35 Joint Program Office still does not have a mature, fully working property program. It has not provided program-specific instructions or training to the officers who must track government property.

GAO’s latest review said this problem is not only on paper. As of March 2026, more than 17,000 parts were missing from the F-35 inventory system. Those parts were valued at about $1.3 billion based on available data, with possible higher totals when full costs are added, according to outside reporting on the GAO findings. GAO stressed that poor records hurt accountability and weaken the Pentagon’s financial statements for this flagship program.

Earlier alarms and lingering gaps in the global spares pool

In 2023, GAO found the F-35 office could not provide total cost, quantity, and location data for government-owned spare parts held at many facilities worldwide. The office relied on contractor records rather than its own complete system. That report flagged that the government did not oversee or account for parts at non-prime contractor locations. Later coverage noted more than 1 million parts worth over $85 million from the 2023 review still lacked clear status by March 2026.

These findings fit a broader pattern of Defense Department inventory problems. GAO has for years documented bad records, weak physical counts, and slow investigations of discrepancies across several services. The F-35 case shows how gaps grow at the seams between government ownership and contractor custody across many sites and systems. That fragmentation can block fixes, even when leaders say they are adding reforms and better tools. The cost is trust, readiness, and basic stewardship of taxpayer dollars.

Program’s promised fixes and what remains unknown

The F-35 program office and Lockheed Martin say new systems will improve tracking. They point to a logistics dashboard and analytics meant to give real-time visibility into parts, spot anomalies, and drive faster orders. They also cite a plan to pair aircraft production with parts buying to stabilize supply and improve readiness. Those claims describe intent and tools, but they do not refute GAO’s concrete findings about missing procedures, weak training, and unreliable records today.

GAO’s numbers require careful reading. The $31 billion figure is the total value of the F-35 parts inventory, not the amount proven lost. The more than 17,000 parts listed as missing reflect gaps in the inventory system; some items may later be found or have incomplete cost data reported. Still, auditors say the current controls cannot ensure that records match reality across hundreds of locations. Until that changes, both conservatives and liberals have reason to worry that the system favors contractors and bureaucracy over taxpayers and troops.
