F-35 Stealth Parts Diverted to Hong Kong Raise Security Concerns

Key points

• UPS was transporting F-35 components from Australia to the U.S. in late May when the shipment was diverted to Hong Kong.
• The diverted parts included a cockpit canopy and weapons bay door coated with radar-absorbing material to enhance stealth capabilities.
• Australian Defense Minister Richard Marles stated that no sensitive parts were in the missing shipment, but Australia is assisting the U.S. and Lockheed Martin in the investigation.
• The incident has prompted concerns from U.S. lawmakers about Chinese access to F-35 technology, particularly following a recent $24 billion sale of the aircraft to Saudi Arabia.
• Lockheed Martin, UPS, and the Pentagon did not immediately respond to requests for comment regarding the diversion.

Background

This incident follows earlier reports in September 2026 of F-35 components being diverted to Hong Kong during transit from Australia to the U.S., which triggered joint investigations by the Pentagon and Australian Defence Department. Previous coverage noted that while officials asserted the parts posed low risk, the incident raised concerns about Chinese access to sensitive military technology. The current report confirms the specific parts involved and the ongoing investigation, with additional context on the recent F-35 sale to Saudi Arabia and congressional concerns.

Why it matters

The diversion of F-35 components to Hong Kong highlights vulnerabilities in the supply chain for advanced military technology and raises concerns about potential Chinese access to stealth capabilities. The incident has prompted investigations by U.S. and Australian authorities and has drawn attention to the security implications of F-35 sales to countries like Saudi Arabia, where lawmakers have expressed concerns about technology reaching Chinese hands.

What to watch

The U.S. and Australian authorities, along with Lockheed Martin, are expected to continue investigating the diversion and work to recover the missing components. Congress may further scrutinize the security implications of F-35 sales, particularly to Saudi Arabia, and may push for stronger safeguards in the supply chain for advanced military technology.
