U.S. Navy Sailor Convicted of Selling Ship Secrets to China

A U.S. Navy sailor has been convicted of passing sensitive ship details to a Chinese intelligence officer, marking the latest case in a series of espionage incidents straining Washington–Beijing relations. The sailor, who sold manuals, images, and ship movement data for cash, now faces life imprisonment in what officials call a dangerous breach of naval security.

How the Espionage Unfolded

The U.S. Department of Justice said Wei was first contacted online in February 2022 by a Chinese intelligence officer who posed as a naval enthusiast linked to the China Shipbuilding Industry Corporation. Between March 2022 and August 2023, Wei provided images, ship location updates, and descriptions of mechanical issues aboard the USS Essex and other vessels at Naval Base San Diego.

One of his most serious leaks involved selling 30 technical and operational manuals on U.S. Navy systems, even though the documents carried export control warnings.

Legal and Strategic Fallout

Wei’s defense argued prosecutors exaggerated the sensitivity of the material. But the conviction highlights the U.S. Navy’s vulnerability to insider threats at a time when Washington is racing to counter China’s rapid naval expansion.

The Pentagon noted in its 2024 report to Congress that the PLA Navy’s modernization enables China to project power farther from its shores for longer periods, making leaks of operational data particularly damaging.

A Pattern of Espionage Cases

Wei’s conviction follows the case of Zhao Wenheng, another Navy sailor sentenced in 2024 to 27 months in prison for providing nonpublic details on Navy training, operations, and infrastructure in exchange for bribes.

Together, the cases underscore what U.S. officials describe as a “shadow war” of intelligence gathering between Washington and Beijing, with China tightening controls on online military content even as the U.S. seeks to curb leaks.
