A shipment of F-35 parts en route from Australia to the US for repairs was rerouted mid-Pacific and turned up in China's Hong Kong instead, Politico reported Friday, September 18, 2026, per Anadolu Agency's account of that reporting. The diversion has triggered a congressional inquiry into how it happened and who has the parts now. Among the shipment's contents was an F-35 canopy - the cockpit enclosure, which incorporates stealth technology available only to the US and its allies. The parts were being transported by an intermediary for F-35 manufacturer Lockheed Martin. It remains unclear why the shipment was diverted or who currently possesses the missing components.
Congress has been getting briefed on it since June
State Department and Pentagon officials began briefing congressional staff on key national security committees in June. Further briefings are expected. The Pentagon's F-35 Joint Program Office confirmed it is "aware of a shipment issue of unserviceable F-35 Lightning II components" and said it is working with US authorities and industry partners "to retrieve these components, investigate the incident, and place safeguards to avoid a future occurrence."
A canopy is small, but it is not nothing
The F-35's canopy carries a coating that is part of what makes the jet's radar signature what it is. Hong Kong is a Chinese special administrative region, so the diversion put the equipment within Beijing's reach even without anyone proving how it got there. J.J. Gertler, a former House Armed Services Committee staff member, told Politico: "It's no secret that China has been aggressively trying to get F-35 data through electronic espionage, among other means. But even if they already had specifications or other data about the part, possessing a real one can give them even more to go on and can verify or refine whatever they already had learned."
The F-35 is the aircraft NATO's eastern flank is betting on
The Netherlands and Denmark already fly F-35 squadrons, and Poland, Belgium, and Finland are mid-buildout on their own fleets - the jet is the backbone of the alliance's answer to Russian air power along its eastern border. A leak that helps an adversary refine countermeasures against the F-35's stealth signature is a problem for exactly the airspace AirVeto tracks, not a separate one - whatever compromises the jet's radar profile compromises the plane the region is counting on to hold that airspace.
