One unread email, one lost F-35 part: how China got US stealth secrets

A misdirected air freight shipment handed Beijing an unexpected windfall: components belonging to an Australian F-35 stealth fighter ended up in China. Fresh reporting traces the chain of mistakes back to a single email that may never have reached the right inbox.


The shipment left Australia in late May 2026 with the United States as its destination. It never arrived in San Francisco. The parts — a cockpit canopy and weapons-bay doors coated with radar-absorbing material — were taken over by China, most likely as the result of an error. In June the Pentagon tried to get them back, and in September Congress was briefed on the details. Politico brought the case into the open that same month, and journalists at Bloomberg later established further specifics.

According to Bloomberg’s findings, a message from the freight company DSV, acting on behalf of Lockheed Martin Corp., the manufacturer of the F-35, informed UPS that the components could not be carried through certain countries in order to preserve compliance with the American International Traffic in Arms Regulations (ITAR).

A shortcut that led to Hong Kong

The cargo was originally meant to travel from Australia to San Francisco by way of South Korea and Taiwan, both of which are US defense partners. The consignment fell behind schedule and was mistakenly routed through Hong Kong instead, in an attempt to accelerate the delivery.

The DSV email flagged the ITAR designation as required under US rules. Bloomberg reports that the message may have been sent through a different IT system than the one in use by the UPS agent handling the shipment — a gap that could explain why the warning failed to stop the rerouting.

The previously undisclosed details of the diverted shipment were presented by Pentagon officials on 29 September, during a meeting that ran for roughly an hour with staff members of the House Foreign Affairs Committee and the House Armed Services Committee.

Investigations and a supply-chain review

The newly reported facts cast the episode in a sharper light. They raise the possibility that a sequence of blunders unintentionally allowed China to obtain access to some of the most sensitive military technologies the United States possesses.

The affair turned out to be compromising for the Pentagon and for Lockheed Martin. It prompted both the Pentagon and the State Department to launch investigations.

American legislators were also alarmed by the incident and demanded a review of the global supply chain for US weaponry, so that a similar failure cannot happen again. The case has become a test of how carefully restricted defense components are tracked once they leave the hands of the armed forces that own them.

The F-35 is the most advanced combat aircraft in the world and the most expensive US armament program in history, which is why even a single misplaced shipment of its parts attracts scrutiny at the highest levels in Washington.
