Pentagon Probes Diversion of F-35 Stealth Fighter Components to Hong Kong

United States defense authorities are investigating how sensitive components belonging to an F-35 stealth fighter jet were diverted through South Korea to Hong Kong, where Chinese authorities have taken possession of the hardware. The shipment, managed by United Parcel Service in late May, contained a cockpit canopy and a weapons-bay door originating from an Australian military aircraft sent to the US for inspection and possible repair or disposal.

Bae Systems Australia previously established an F-35 regional warehouse facility in New South Wales to support aircraft in the region. Meanwhile, the United States incurred millions in non-recurring engineering expenses to adjust supply chain networks.

The intercepted equipment was manufactured by Lockheed Martin Corp. and coated with specialized radar-absorbing material designed to minimize radar detection. While the exact reason behind the detour through South Korea and Hong Kong remains unclear, the Chinese government has retained custody of the components without returning them, triggering intense scrutiny across Washington as high-level diplomatic talks commenced.

Disclosure of the incident coincided with the arrival of Chinese President Xi Jinping in Washington for a state visit hosted by President Donald Trump. Lawmakers on multiple congressional panels, including the House Foreign Affairs and Armed Services committees alongside the Senate Armed Services airland subcommittee, have initiated inquiries into how classified military hardware fell into foreign hands.

Senator Elissa Slotkin criticized the timing during a media appearance, noting the contradiction between welcoming a foreign leader and losing custody of advanced military assets to an acknowledged strategic competitor. Congressional investigators are examining supply-chain vulnerabilities, while the Pentagon stated it is actively collaborating with industry partners to retrieve the components and prevent future breaches.

Defense officials and prime contractors have offered differing perspectives regarding the sensitivity of the diverted hardware. A spokesperson for Lockheed Martin in Australia stated that the components in question were unserviceable and deemed to be at low risk for intelligence exploitation.

Australian Defense Minister Richard Marles acknowledged that the jet parts ended up in Hong Kong but maintained that the missing items did not constitute sensitive equipment. In contrast, independent defense analysts emphasize that any physical access to radar-absorbing coatings and structural assemblies provides potential engineering insights into fifth-generation fighter technology.

Transport provider UPS disclosed the incident to the State Department Directorate of Defense Trade Controls out of an abundance of caution, though company representatives declined public comment. Australian defense officials confirmed they are reviewing local handling procedures while emphasizing confidence in their engagement with the broader multinational program.

The F-35 Joint Program Office confirmed that it is working alongside US authorities to establish enhanced safeguards. During a closed Senate Armed Services Committee hearing, program officials expressed confidence that diplomatic and investigative channels would eventually secure the return of the components.
