Australian Defence Minister Richard Marles has confirmed that a shipment of F-35 fighter jet components sent to the United States for repair was accidentally misrouted to Hong Kong during transit, with key parts remaining missing.
Australia is working alongside the US administration and defense contractor Lockheed Martin to investigate how the military cargo veered off course and reached the Chinese special administrative region.
The incident was first reported by news outlet POLITICO on September 18. According to reports, a group of F-35 components shipped from Australia to the United States by a subcontractor handling transit on behalf of Lockheed Martin went off course during shipment and arrived in Hong Kong. Authorities have not yet clarified why or how the parts were redirected.
Among the misrouted items was an F-35 cockpit canopy coated with radar-absorbing material, which is reported to still be missing. The coating is a key feature that contributes to reducing the aircraft's radar visibility and maintaining its stealth capabilities during flight.
The F-35 Lightning II, manufactured by Bethesda-based aerospace company Lockheed Martin, is a fifth-generation stealth multirole fighter jet operated by the US military and international allies, including the Royal Australian Air Force. Its low radar visibility design relies on advanced composite materials and specialized coatings to prevent detection by enemy air defense systems.
Australian review and responsibility
Marles stated that the Australian government is reviewing its own internal processes regarding the event, while stating that he does not believe the missing components were sensitive in nature. He said no sensitive parts were involved and expressed confidence that Australia's contributions to the global F-35 program are being managed securely on its side.
Marles added that ultimate responsibility for managing the shipment rests with the United States and the program's prime contractor, Lockheed Martin.
The F-35 Joint Program Office within the Pentagon described the lost items as out-of-service F-35 Lightning II components. US authorities stated that they are working with defense industry partners to retrieve the parts, investigate the incident, and implement new security protocols to prevent a similar situation from recurring.
The F-35 Joint Program Office operates within the Pentagon, the Arlington, Virginia headquarters of the US Department of Defense, overseeing procurement and fleet support across international partner nations. Equipment logistics are governed by standards established by the US Department of Defense and its Defense Logistics Agency.
Lockheed Martin and security concerns
Lockheed Martin stated that it will not disclose shipment details due to security reasons. The contractor stated that it complied with rules set by the US Department of Defense and the Defense Logistics Agency, adding that the components were considered unusable and presented a low risk for potential misuse.
Despite those assurances, the arrival of the components in Hong Kong has revived security concerns over sensitive F-35 technologies falling into Chinese hands. Hong Kong is a special administrative region of China, where US officials have long maintained caution over the possibility of Beijing gaining access to technological data regarding advanced American weapon systems.
The low radar visibility design and advanced hardware of the F-35 are among its primary advantages on the battlefield. Acquiring components or technical details could assist a potential rival in gaining a better understanding of the aircraft's detection and countermeasure systems.
