What does it do when one engineer just walks out the door with blueprints to America’s eyes in the sky? The recent guilty plea of Chenguang Gong, a dual citizen of the United States and China, gives us a rare, unvarnished glimpse into the machinery of high-level technology theft and the international competition for military dominance one in which infrared sensors and missile detection systems are as highly prized as gold.
Gong’s prosecution in the Central District of California is representative of the larger espionage threat to U.S. defense contractors. Gong was employed in January 2023 as an application-specific integrated circuit design manager and was tasked with creating and verifying advanced infrared sensors. Within weeks, he had downloaded more than 3,600 confidential documents many bearing the notation “proprietary” and “export controlled” from his work laptop onto personal devices. Federal prosecutors stated that “These files describe the methods, designs, techniques, processes, specifications, testing, and manufacture of these technologies and would be extremely damaging economically if obtained by the victim company’s competitors, and would be dangerous to U.S. national security if obtained by international actors.”
The purloined cache contained blueprints for space-based infrared sensors that form the U.S. military’s missile warning infrastructure. These sensors, forming the nucleus of the Space Based Infrared System, enable early warning of hypersonic, ballistic, and nuclear missile launchings. SBIRS uses a constellation of satellites in geosynchronous and highly elliptical orbits with scanning and staring infrared payloads to detect the minute heat signature of missile plumes against the frigid background of space. The most recent generation, the Overhead Persistent Infrared, takes it a step further with higher sensitivity, quicker revisit rates, and more sophisticated on-board processing, allowing the U.S. to “characterize battlespace and gather technical intelligence” with unparalleled accuracy Space Based Infrared System offers sophisticated space surveillance and missile warning.
But Gong’s pilferage went beyond orbital platforms. Among the documents were proposals for infrared warning sensors on missiles going to American fighter planes systems designed to recognize the characteristic signature of oncoming heat-seeking missiles and to activate countermeasures like flares or jamming. The design philosophy of these airborne sensors is founded upon distinguishing between real threats and background noise, by utilizing multi-spectral detection, real-time signal processing, and machine learning algorithms to reduce false alarms and maximize pilot survivability.
This violation did not take place in isolation. Gong’s career, which extends almost a decade, illustrates a consistent interaction with China’s “Talent Programs” specifically the Thousand Talents Program, a government-run program that seeks to attract overseas experts and transfer dual-use technology to China’s civilian and military domains. As the FBI has cautioned, the Chinese government attempts to lure scientists into bringing our knowledge and innovation back to China secretly, even if that means pilfering our proprietary information or breaking our export controls and conflict-of-interest policies The Thousand Talents Program, which began in 2008, is China’s most visible talent-recruitment program. Gong himself proposed to Chinese institutions the development of high-performance analog-to-digital converters and low-light image sensors technologies with clear utility for radar, nighttime vision, and missile guidance.
The case highlights the distinct challenge presented by China’s strategy of military-civil fusion, which programmatically erodes the distinction between civilian research and military use. This strategy, combined with intense talent recruitment and the requirement that participants “place China’s interests above their U.S. employers,” has driven a spate of intellectual property raids in key industries. The U.S. Department of Justice has described such programs as “a whole-of-state effort” to steal innovation, involving contracts that typically call for secrecy, dual affiliations, and the creation of “shadow labs” in China to copy and exploit U.S.-funded work.
The United States has, in turn, raised its legal and regulatory countermeasures. Export controls on top-level semiconductors and AI-enabling hardware have been tightened repeatedly since 2022, extending to the design software and manufacturing equipment necessary for next-generation devices. Both Trump and Biden administrations have employed the Foreign Direct Product Rule to stretch U.S. authority around the world in an effort to cut off China’s ability to access the best computational hardware. However, as recent events have attested, semiconductor chips are made by the millions and are small and easily hidden, and design software can very probably be transferred across borders undetected the imposition of export controls has served to cause China to double down on its current deeply subsidized development strategies.
The technical challenge is made even more formidable by the threat landscape shift within defense contractors themselves. Insider threats whether careless, malicious, or compromised now account for a significant share of breaches. According to the Verizon 2023 Data Breach Investigations Report, 74% of all breaches involve the human element, with insider incidents rising 44% since 2020 Insider threats have increased 44% since 2020 due to current market dynamics. Best practices today require real-time observation, behavioral analysis, and effective security awareness campaigns to detect and neutralize exfiltration before it turns into a national security emergency.
Gong’s prosecution is just the latest in a series of cases revealing the weaknesses of America’s innovation ecosystem. With the U.S. Attorney’s Office noted, the stolen sensor designs “would be dangerous to U.S. national security if obtained by international actors.” With sentencing scheduled for September and the potential for a decade in prison, the message is clear: the intersection of engineering, espionage, and export control is now a frontline in the global struggle for technological and military dominance.
