An F-35 cockpit canopy and a weapons-bay door shipped by UPS from Australia to the United States in late May were diverted to Hong Kong following a stopover in South Korea.
Chinese officials took possession of the components, which feature radar-absorbent materials, while Beijing's Foreign Ministry stated it was unaware of the situation.
At least two congressional committees initiated investigations, with Senator Elissa Slotkin criticizing the incident as Chinese President Xi Jinping arrived for a state visit.
Australian Defense Minister Richard Marles and the Pentagon noted the parts were unserviceable items sent for repair or disposal, while the F-35 Joint Program Office coordinates recovery efforts.
A commercial freight delivery transporting key components from an Australian F-35 stealth fighter ended up in Hong Kong, where Chinese authorities took possession of the equipment. The shipment, handled by United States logistics firm UPS, departed Australia in late May destined for American facilities for technical inspection, repair, or destruction. The cargo aircraft made a scheduled stopover in South Korea before being unexpectedly routed to Hong Kong for reasons that remain under investigation. Chinese officials retained the hardware, while the Chinese Foreign Ministry in Beijing claimed it had no knowledge of the shipment and the Chinese Embassy declined to provide comment.
The seized shipment contains two distinct aircraft parts manufactured by prime contractor Lockheed Martin: a cockpit canopy and an internal weapons-bay door. Both components incorporate specialized radar-absorbent materials engineered to minimize radar cross-section and preserve the aircraft's stealth capabilities. The canopy features a thin transparent layer that allows pilot visibility while scattering radar signals, while the internal bay door maintains outer fuselage stealth contours around weapons compartments. The Pentagon and Lockheed Martin described both items as unserviceable components carrying low security risk. However, Michael Shoebridge, director of Strategic Analysis Australia, noted that foreign intelligence services could study the physical alloys and coatings to identify radar detection vulnerabilities or reverse-engineer manufacturing processes.
The public emergence of the logistics failure coincided with Chinese President Xi Jinping landing at Joint Base Andrews on Wednesday for a state visit with President Donald Trump. At least two congressional committees in Washington initiated formal inquiries into how defense equipment entered Chinese territory during commercial transit. Lawmakers voiced concern over the transfer, pointing to the timing of the diplomatic reception.
“The Chinese have their hands on some of our most sensitive technology and we are rolling out the red carpet for their president.”
Slotkin, speaking to Bloomberg, stated that China remains an active military and intelligence adversary seeking data on Western hardware, though she noted she had not received classified briefings on the matter.
The Pentagon, the F-35 Joint Program Office, and Australian defense authorities launched parallel reviews to trace the shipping error and recover the hardware. More than 1,200 F-35 aircraft operate globally across partner militaries, including Australia, the United States, and allied purchasers such as Poland, which ordered 32 jets. Australian Defense Minister Richard Marles confirmed the delivery to Hong Kong during a press briefing on Tuesday, while seeking to reassure allies regarding the nature of the lost parts.
“My understanding is that there is a sense of comfort, and we're not talking about sensitive equipment here or sensitive parts. Ultimately, though, this is an issue which is going to be managed by the United States and by Lockheed in terms of what has occurred.”
The F-35 Joint Program Office stated that American officials are working with industry partners to retrieve the parts and introduce stricter logistical safeguards to prevent similar diversions in the future.
