Pentagon Investigating Diversion of F-35 Fighter Jet Parts to China

A confirmed diversion of classified U.S. Weapons components to a strategic adversary raises questions about supply chain oversight within the Department of Defense procurement system.

The Pentagon is actively investigating how a shipment of F-35 fighter jet components was diverted from its intended destination and reportedly ended up in China's possession, according to CBS News, which first reported the story on September 24, 2026, citing an earlier Bloomberg News report.

U.S. Officials confirmed the investigation is ongoing and said the government is working to retrieve the parts. The specific components involved, their quantity, and the point at which the diversion occurred have not been publicly disclosed by the Department of Defense as of the date of this report.

The F-35 Lightning II is manufactured by Lockheed Martin under a series of contracts with the U.S. Department of Defense. According to USASpending.gov, Lockheed Martin has received more than $60 billion in F-35-related prime contract awards since the program's inception. The aircraft is considered one of the most technologically sensitive platforms in the U.S. Military inventory, incorporating stealth materials, sensor fusion systems, and proprietary avionics.

The F-35 program operates under a multi-tier supply chain involving hundreds of domestic and international subcontractors. The program's Joint Program Office, housed within the Office of the Secretary of Defense, is responsible for acquisition oversight. Which node in that supply chain allowed the diversion to occur is not yet publicly known. The Defense Contract Audit Agency or the Defense Criminal Investigative Service would be the bodies most likely to generate public records identifying the breach point.

Export of F-35 components is governed by the International Traffic in Arms Regulations, administered by the State Department's Directorate of Defense Trade Controls. Unauthorized transfer of controlled defense articles to a foreign national or government is a federal criminal offense under 22 U.S.C. Section 2778. Whether any criminal referral has been made is unknown at this time.

China is designated a strategic competitor under the 2022 National Defense Strategy, a document published by the Department of Defense. U.S. Law, specifically the National Defense Authorization Act for Fiscal Year 2019, restricts certain technology transfers to China through amendments to the Export Control Reform Act. Whether those statutes are directly applicable to the parts in question depends on their specific classification, which has not been publicly released.

The House Armed Services Committee and the Senate Armed Services Committee both hold oversight jurisdiction over Defense Department procurement and security. As of publication, neither committee has issued a public statement or announced a hearing related to this incident. Committee hearing schedules are published on congress.gov.

This is not the first reported instance of defense supply chain compromise involving China. A 2019 Department of Justice press release documented the conviction of a U.S. Navy contractor for exporting submarine-related technical data to China. The current case involves a different platform and, based on available reporting, a different mechanism of diversion.

The Pentagon has not released a formal statement identifying the specific parts, the contractor responsible for the shipment, the carrier, or the customs and logistics records that would document the chain of custody. Those records, if made public or subpoenaed by Congress, would be the primary document set needed to establish accountability.

Several questions remain unanswered by publicly available information: which specific subcontractor shipped the components, whether the diversion was the result of theft, fraud, or administrative error, whether foreign nationals with authorized access were involved, and at what stage of the supply chain the breach occurred. The Defense Contract Management Agency's shipment verification records and U.S. Customs and Border Protection export declarations would be the documents most likely to answer those questions.

This story will be updated as the Department of Defense releases additional information or as congressional oversight activity generates public records.
