F-35 Parts Diverted to Hong Kong Highlight Supply-Chain Gaps
By Drooid · · How we work
Core Incident
In late May 2026 a cockpit canopy and a weapons-bay door from an Australian-operated F-35A were being returned to the United States for possible repair or disposal. Both components were coated with radar-absorbing material. A freight-forwarder, DSV A/S, emailed UPS warning that the shipment was subject to U.S. International Traffic in Arms Regulations (ITAR) and could not transit certain countries. According to a Bloomberg investigation published on October 7 2026, a UPS employee failed to act on the warning, and the consignment was rerouted through Hong Kong to accelerate delivery. Chinese authorities subsequently took possession of the parts. The Pentagon briefed staff of the House Foreign Affairs and Armed Services committees on September 29 2026 about the diversion.
Background & Context
ITAR is designed to prevent sensitive U.S. defense technology from reaching adversaries. A Government Accountability Office (GAO) report released in June 2026 noted that the Department of Defense still could not fully account for components moving through the fighter’s global spare-parts network. An earlier May 2023 GAO review found that one prime contractor had recorded losses of more than one million spare parts valued at over $85 million since May 2018, with the F-35 Joint Program Office reviewing fewer than 2 percent of those losses. The same investigation identified more than 19,000 spare parts awaiting disposal instructions, some for as long as five years.
Data & Statistics
- Components involved: one cockpit canopy and one weapons-bay door, both with radar-absorbing coating.
- GAO 2023 loss figures: >1 million parts, >$85 million value, <2 % reviewed.
- Backlog: >19 000 parts awaiting disposal, some for up to five years.
Official Statements & Responses
- Australian Defence Minister Richard Marles (speaking at RAAF Base Edinburgh on September 22 2026) said Australia was examining its handling of the shipment but emphasized that responsibility for the broader investigation rested with the United States and Lockheed Martin.
- Pat Conroy, Defence Industry, declined to comment on specifics pending investigations.
- Erica Plath, deputy assistant secretary of defense for logistics, told congressional staff her team was assembling safeguards to prevent a repeat.
- State Department: A compliance official from the Directorate of Defense Trade Controls confirmed an ongoing investigation into the export-control breach.
Criticism & Opposition
- Senator Mark Warner (ranking Democrat, Senate Intelligence Committee) and Senator Tom Cotton (chair, Senate Armed Services Committee) have demanded a comprehensive supply-chain review.
- Senator Kevin Cramer (Armed Services Committee chair) asked whether China had a pre-existing plan to intercept the shipment.
Conflicting Reports & Gaps
The Pentagon’s characterization of the parts as “unserviceable” contrasts with GAO and expert concerns that the radar-absorbing coatings could reveal aspects of the aircraft’s low-observable technology. No public evidence confirms that China has extracted usable stealth data, and investigators have not disclosed where the parts are currently held. The investigation remains open, leaving the extent of any technical compromise unresolved.
What’s Next
The Pentagon, State Department, and Lockheed Martin continue joint investigations, while congressional committees pursue oversight hearings. Lawmakers have called for tighter ITAR enforcement and improved inventory tracking across the F-35 supply chain. The outcome of these reviews will shape future logistics protocols for the program.
