Chinese Authorities Reportedly Take Custody of Diverted F-35 Stealth Fighter Components in Hong Kong

A commercial UPS shipment transporting two unserviceable Australian F-35 stealth fighter components—a cockpit canopy and a weapons-bay door—was unexpectedly diverted to Hong Kong via South Korea instead of reaching its intended destination in the United States. Chinese authorities subsequently took possession of the parts, which feature radar-absorbing stealth coatings, and have not returned them. The incident has triggered joint investigations by the U.S. Department of Defense, Australian authorities, and manufacturer Lockheed Martin to determine how the logistics failure occurred, while highlighting ongoing vulnerabilities in global defense supply chain tracking.

// Background

The F-35 Lightning II is a fifth-generation stealth multi-role combat aircraft developed by Lockheed Martin, with access strictly controlled by Washington for select allies including Australia. The global supply chain relies on shared international spare parts pools. Historical tracking and security issues have surrounded the program: a 2023 U.S. Government Accountability Office report revealed that contractors had lost track of over one million spare parts worth approximately $85 million, with fewer than 2% reviewed by the DoD. Additionally, Chinese cyber actors previously targeted the F-35 program, including recorded breaches in 2007 and 2012, while foreign sales have faced strict scrutiny to avoid technological compromise.

// Key Developments

• A shipment containing an F-35 cockpit canopy and weapons-bay door en route from Australia to the U.S. was diverted to Hong Kong after stopping in South Korea.
• Chinese authorities reportedly took possession of the components, which remain unreturned.
• Both parts are coated with radar-absorbing material designed to minimize radar signatures and enhance stealth capabilities.
• The Pentagon's F-35 Joint Program Office, Lockheed Martin, and Australian defense officials are investigating the diversion and attempting to retrieve the equipment.
• Australian Defense Minister Richard Marles downplayed risks, characterizing the unserviceable parts as not sensitive, despite conflicting concerns regarding exposure of low-observable technology.
• The incident underscores existing scrutiny over F-35 supply chain oversight, recalling a 2023 GAO report noting over one million untracked F-35 spare parts.
