GAO: 17,000 F-35 Parts Worth Up to $2.5B Not Recorded in Pentagon Logistics System
The ELMS-to-contractor interface gap is the load-bearing problem: until Lockheed Martin and Pratt & Whitney feed real-time data into the government's system, every audit will find the same discrepancies regardless of how many remediation cycles the F-35 Joint Program Office runs.
If the subcontractor visibility gap is also unresolved — the GAO notes prime contractors are not always aware of inventories held by their subcontractors — then the $31 billion pool has no single authoritative record anywhere in the supply chain.
The F-35 Joint Program Office is running a $31 billion spare parts pool across the Air Force, Navy, Marine Corps, and international customers with inventory data that is at minimum three months stale, because ELMS does not interface in real-time with Lockheed Martin's or Pratt & Whitney's property management systems.
With the Air Force awarding Lockheed Martin a $1.6 billion spare parts contract in July, new parts are entering a system that cannot confirm where existing ones are — including over 1 million parts that went missing between 2018 and 2022 whose status the F-35 Joint Program Office still does not know as of March 2026.
The next GAO follow-up cycle will show whether the July contract award required any accountability remediation as a condition.
Did the Air Force's July 2026 $1.6 billion spare parts contract with Lockheed Martin include any contractual requirement to resolve the ELMS interface gap or reconcile the missing 1 million-plus parts from 2018–2022, or was it awarded against the same unresolved accountability baseline?
