Missing F-35 Stealth Fighter Components Diverted to Hong Kong Spark U.S. Security Probe
A shipment of F-35 fighter jet components, including a stealth cockpit canopy, was diverted from Australia to Hong Kong, raising fears of Chinese access to classified U.S. technology.
A sensitive shipment of F-35 stealth fighter components, en route from Australia to the United States for repairs, was unexpectedly diverted to Hong Kong and disappeared, raising concerns that China may gain access to classified U.S. military technology, Politico reported on Friday. According to three sources familiar with the matter, the shipment originated in Australia and was scheduled to arrive in the United States. However, for reasons still unclear, it was diverted during transit and reached Hong Kong. It remains uncertain who currently holds the components or whether they have already been transferred to Chinese authorities.
The shipment was handled by a third-party intermediary for Lockheed Martin, the manufacturer of the F-35. The Pentagon confirmed that some components are missing. The F-35 Joint Program Office stated that it is aware of an issue involving a shipment of non-serviceable F-35 Lightning II components and is working with U.S. authorities and industry partners to recover the items, investigate the incident, and implement safeguards to prevent similar occurrences.
The Missing Canopy and Potential Technology Exposure
Two sources told Politico that the shipment included an aircraft cockpit canopy. The canopy is not merely a transparent shield protecting the pilot, but a critical component of the F-35 stealth architecture. It is coated with a thin, radar-absorbent material designed to minimize the aircraft's radar cross-section and evade enemy radar systems.
Physical access to the canopy could allow a rival nation to examine its materials and manufacturing techniques, compare them with existing intelligence data, and potentially attempt reverse engineering. It is no secret that China aggressively targets F-35 technology through electronic espionage and other means.
Congressional Briefings and Supply Chain Vulnerabilities
The undisclosed incident triggered a series of briefings for members of key national security committees in Congress. Representatives from the State Department and the Pentagon conducted the initial briefing in June, with additional briefings scheduled for the coming weeks. The transfer of military hardware to Hong Kong has drawn intense scrutiny in Washington amid tightening Beijing control over the territory.
The F-35 global supply chain relies on facilities across multiple nations for manufacturing, transport, and maintenance. Australia hosts maintenance hubs, but none are currently capable of repairing F-35 canopies, necessitating shipment to the United States. The incident compounds prior supply chain criticisms, including a 2023 Government Accountability Office report revealing that over a million F-35 spare parts had gone missing over a five-year period.
