WASHINGTON (Sept. 18, 2026) — The Pentagon is investigating how a shipment of unserviceable F-35 Lightning II components traveling from Australia to the United States for repairs was rerouted across the Pacific to Hong Kong and is now unaccounted for, raising concern that sensitive stealth-related hardware could be studied by China.

According to reporting by Politico — carried and confirmed in outline by the Washington Examiner, Aviacionline, and other outlets Friday — the shipment included one of the jet’s acrylic cockpit canopies, which incorporates radar-absorbent / stealth coating available only to the United States and its F-35 partners. An intermediary transporting the parts on behalf of manufacturer Lockheed Martin diverted the load; it remains unclear why the route changed or who controls the components now.

The Pentagon’s F-35 Joint Program Office told Politico it was “aware of a shipment issue of unserviceable F-35 Lightning II components” and is working with U.S. authorities and industry partners “to retrieve these components, investigate the incident, and place safeguards to avoid a future occurrence.” Lockheed said its teams “handle every shipment with the utmost diligence and safeguards to ensure the integrity of the F-35 program and the security of our allied partners.”

Congress briefed; China access not confirmed

State Department and Pentagon officials first briefed congressional national-security staff on the episode in June, with further briefings expected, people familiar with the matter told Politico. Lawmakers are pressing for a fuller accounting of how classified program hardware left the planned repair pipeline.

No outlet has confirmed that Chinese authorities or contractors obtained the parts, or that the diversion was a coordinated intelligence operation. The Chinese Embassy told Times Now it was not familiar with the incident; the State Department declined comment. Military-aviation analyst J.J. Gertler (former House Armed Services staff / CRS) told reporters that China has long sought F-35 data through cyber espionage and other means, and that a physical component could help an adversary “verify, refine, or audit” information already collected digitally.

The episode lands on a logistics network already flagged by oversight: a 2023 Government Accountability Office report found more than 1 million F-35 spare parts had gone missing over five years and said DoD could not fully review losses worth tens of millions of dollars because Lockheed controlled key data — a separate accountability problem from Friday’s Hong Kong diversion, but one that underscores how hard it is to track unserviceable parts across a multinational repair chain.

This investigation is distinct from the separate September story on a possible $24.3 billion Saudi F-35 sale package; Friday’s reporting is about missing repair-bound components, not a foreign military sale.
