Wei, also known as Patrick Wei, was arrested in August 2023 while reporting for duty on the USS Essex, having previously served as a machinist's mate with access to sensitive military data. His recruitment by a Chinese intelligence agent began in February 2022, during his citizenship process, initially by posing as a naval enthusiast. Evidence presented at the trial included various communications with his handler, who was referred to as "Big Brother Andy," showcasing Wei's deliberate efforts to maintain secrecy and accept payments through encrypted methods.

Compromising sensitive military information, Wei transmitted images and insights from the USS Essex, earning over $12,000 over 18 months in return. Notably, a text exchange with his mother revealed his awareness of the seriousness of his actions, as he sarcastically compared his espionage work to other Chinese individuals in the US Navy who sought legitimate employment. Wei's sentencing is scheduled for December 1, where he may face life in prison.

His arrest coincided with that of Petty Officer Wenheng Zhao, who had been previously convicted for providing sensitive operational details to a Chinese intelligence officer, demonstrating a troubling trend within the Navy.

The Wei case not only exemplifies the threats posed by espionage but also raises critical questions about security protocols and the potential vulnerabilities within the military.
