Silicon Valley Engineer Pleads Guilty to Stealing Missile Detection Data for China

A dual U.S.-China citizen and former Silicon Valley engineer has pleaded guilty to stealing critical military technology secrets designed to protect American national security interests. 

Chenguang Gong, 59, of San Jose, admitted to transferring over 3,600 classified files containing advanced missile detection and defense technologies to personal storage devices, with intentions to benefit the Chinese government through their talent recruitment programs.

Key Takeaways
1. Engineer Chenguang Gong pleaded guilty to stealing 3,600+ classified missile defense files for China.
2. Stolen blueprints included advanced infrared sensors and integrated circuits.
3. Gong participated in Chinese talent programs for 8 years, faces 10 years in prison.

US Missile Tech Stolen for China

The stolen technology represents some of America’s most sophisticated defense capabilities, centering on application-specific integrated circuits (ASICs) and readout integrated circuits (ROICs) designed for critical military applications. 

These proprietary systems include blueprints for infrared sensors engineered for space-based missile detection platforms capable of identifying nuclear missile launches and tracking both ballistic and hypersonic missiles. 

The technology also encompasses advanced sensor designs that enable U.S. military aircraft to detect incoming heat-seeking missiles and deploy electronic countermeasures, including sophisticated jamming systems that disrupt the missiles’ infrared tracking capabilities.

During his brief tenure from January to April 2023 at a Los Angeles-area research and development company, Gong systematically transferred files containing trade secrets worth hundreds of millions of dollars. 

The stolen blueprints included specifications for mechanical assemblies used to house and cryogenically cool infrared sensors, as well as “next generation” sensor technologies capable of detecting low observable targets while maintaining enhanced survivability in space environments. 

Many files were clearly marked with security classifications including “PROPRIETARY INFORMATION,” “FOR OFFICIAL USE ONLY,” and “EXPORT CONTROLLED”.

Investigation revealed Gong’s extensive participation in China’s talent recruitment programs spanning from 2014 to 2022. 

He submitted multiple applications proposing to develop high-performance analog-to-digital converters (ADCs) and low-light image sensors for military applications, specifically emphasizing their use in radar systems and missile navigation platforms. 

In his proposals, Gong explicitly acknowledged that these ADCs “directly determine the accuracy and range of radar systems” and are essential components in “missile navigation systems”.

Law enforcement discovered that Gong traveled to China multiple times seeking funding for these projects, despite working for American military contractors. 

The intended economic loss from his criminal conduct exceeds $3.5 million, with Gong facing a maximum penalty of 10 years in prison at his September sentencing.
