Former Navy Sailor Sentenced for Espionage
Jingchao Wei, a 25-year-old former U.S. Navy sailor, was sentenced on Monday to 200 months in prison after he was found guilty of selling sensitive technical information about U.S. ships to Chinese intelligence.
Wei, who is originally from China and also goes by the name Patrick Wei, entered the Navy as a naturalized citizen. His troubles began when he reported for duty at Naval Base San Diego in August 2023. His assigned ship was the USS Essex, a Wasp-class amphibious assault ship known for its versatility and capability of supporting various aircraft.
While serving on the Essex as a machinist, Wei had access to classified information regarding advanced weapon systems and engines. His connections with Chinese intelligence began when agents posing as friendly naval enthusiasts approached him. The Justice Department highlighted that Wei likely realized he was engaging with spies, especially since one of them was associated with a Chinese state-owned shipbuilding company.
Shortly after Wei’s online interactions started, he informed colleagues about being in touch with a person who seemed “highly suspicious” and was probing him about naval maintenance cycles. If he had been deceived, it seems the period of confusion lasted only about eight days. A Chinese agent even offered him $500 for a tour of the Naval Base, to which Wei retorted that he wasn’t “an idiot” and considered the agent “obviously a lousy spy.”
It appears that Wei was quite aware of the risks involved; he moved his conversations with the agents to a secure messaging platform, suggesting that he had much more to offer than just a casual base tour.
The Justice Department reported that Wei sold photographs and videos related to the Essex and shared extensive operational insights about U.S. Navy surface ships, some of which were obtained from secure systems. Furthermore, he leaked information regarding the movements of other naval vessels.
Many of the documents Wei shared were marked with clear warnings about export controls, indicating he understood the legal implications of his actions. His online chats with his handler, whom he named “Big Brother Andy,” revealed an awareness of the need for secrecy. U.S. counterintelligence later confirmed that “Andy” was indeed a Chinese intelligence operative.
From March 2022 to August 2023, Wei received over $12,000 for his illegal activities, and “Andy” even promised him further rewards, including a trip to China for him and his mother.
After his arrest, Wei acknowledged that he was involved in espionage and took steps to hide his actions from both the Navy and law enforcement. He reportedly told the FBI agent involved in his arrest, “I’m extreme up.”
In August, Wei was indicted by a federal jury on several counts, including espionage, and was ultimately convicted on six of seven charges. His defense argued that his role was limited to low-level maintenance work but did not convince the jury.
Wei was dishonorably discharged from the Navy at the end of 2025 and received his sentence from a federal judge in San Diego this week.
Assistant Attorney General for National Security John A. Eisenberg criticized Wei for betraying the oath he took and jeopardizing national security by selling military secrets to Chinese agents.
Similarly, Deputy Attorney General Todd Blanche remarked that Wei’s actions represented a grave betrayal of his country.
Wei’s arrest coincided with that of another Chinese-American sailor, Petty Officer Wenheng Zhao, who was also convicted of providing classified military information to Chinese agents and is set to be sentenced to 27 months in prison in January 2024.
Following these events, Larissa L. Knapp from the FBI’s National Security Division issued a stark warning about China’s aggressive tactics aimed at undermining U.S. national security.
