Pentagon Probes Diversion of Australian F-35 Parts to Hong Kong

F-35 Components Diverted to Hong Kong

The Pentagon is investigating how components from an Australian-operated F-35 fighter jet were unexpectedly diverted to Hong Kong while being shipped to the United States. The F-35 Joint Program Office confirmed a “shipment issue” involving unserviceable parts and said it is working with U.S. authorities and industry partners to recover them.

“We are actively working with U.S. authorities and industry partners to retrieve these components, investigate the incident, and place safeguards to avoid a future occurrence,” the office said.

The shipment was being transported by an intermediary on behalf of F-35 manufacturer Lockheed Martin. It is unclear why the cargo was rerouted or who currently possesses the equipment.

Canopy and Weapons-Bay Door Reported Missing

The shipment originated in Australia and was headed to the United States for repair or possible disposal. Bloomberg reported that it contained a cockpit canopy and a weapons-bay door and that China had obtained the components. Other reporting confirmed the canopy but did not establish the present location or ownership of the parts.

The canopy covers the cockpit and, according to people familiar with congressional briefings, incorporates stealth technology available only to the United States and its allies. Physical access could allow an adversary to examine the component and compare it with previously obtained technical information.

Australian Defense Minister Richard Marles confirmed that the components ended up in Hong Kong but rejected suggestions that they were sensitive.

“My understanding is that there is a sense of comfort, and we’re not talking about sensitive equipment here or sensitive parts,” Marles said. He added that Australia was working with the United States and Lockheed Martin, while responsibility for managing the incident rested with those parties.

Congressional Inquiry Underway

The diversion has prompted an inquiry on Capitol Hill and briefings for staff on national security committees. State Department and Pentagon officials first briefed congressional staff in June, with additional sessions expected.

China’s Foreign Ministry said it was unaware of the incident. The Hong Kong government declined to comment on a specific case, and Lockheed Martin did not immediately respond to a request for comment.

Hong Kong is a special administrative region of China. Beijing has tightened its control over the territory in recent years, including through national security laws. Hong Kong does not maintain its own military or conduct independent diplomacy.

Security Concerns

The F-35 Lightning II is a fifth-generation fighter incorporating stealth coatings, advanced radar, sensors, and networking systems designed to share information with allied aircraft and ground forces. More than 1,200 have been produced, and 19 countries have placed orders, according to the Congressional Research Service.

China has previously been accused of seeking information about the aircraft. A 2013 Defense Science Board report alleged that Chinese cyberattacks accessed data from multiple Pentagon programs, including the Joint Strike Fighter.

J.J. Gertler, a former House Armed Services Committee staff member and military aviation analyst, said possession of an actual component could provide information beyond stolen specifications. A physical part, he said, could help verify or refine data already obtained through electronic espionage.
