Espionage Case Overview
A former Navy sailor from San Diego has received a sentence of over 16 years in prison for espionage after being found guilty of leaking classified military information to China. Jinchao Wei, 25, originally from China and a machinist mate on the USS Essex, was convicted in August on multiple charges including espionage and conspiracy.
The Justice Department reported that Wei was recruited in February 2022 via social media by a Chinese intelligence officer posing as a naval enthusiast affiliated with the state-owned China Shipbuilding Industry Corporation. Despite receiving warnings from acquaintances and harboring his own doubts about the situation, Wei shifted their communications to an encrypted messaging platform and began sharing sensitive data.
From March 2022 until his arrest in August 2023, Wei transmitted images and videos of the USS Essex, revealed the locations of various Navy vessels, and detailed the ship’s defensive systems. He also provided thousands of pages of technical documents stolen from restricted Navy databases, which included at least 30 manuals covering critical systems such as power management and damage control.
Wei held a security clearance that allowed him access to national defense information regarding the Essex’s weaponry and operational systems. Over an 18-month period, he received more than $12,000 for this classified information. Additionally, Chinese intelligence financed travel arrangements for both him and his mother to China.
During the trial, retired Navy officials testified that the leaked information could enable China’s People’s Liberation Army to better understand U.S. amphibious assault ships’ operations and potentially advance their own naval capabilities. This data could also enhance China’s ability to target American warships amid rising tensions concerning Taiwan.
Deputy Attorney General Todd Blanche remarked that Wei had “betrayed his country” while compromising U.S. national security. Prosecutors had requested a sentence of 22 years due to the severity of his actions.
In a handwritten letter addressed to the judge, Wei expressed regret over his decisions, describing himself as “stupid, naïve and careless.” His mother mentioned in her pre-sentencing letter that he relocated from China to Wisconsin in 2016 and embraced Christianity while incarcerated. At the time of his service, Wei held an E4 rank.
