A China-born US researcher pleaded guilty today to stealing trade secret technologies developed for use by the U.S. government.

As per the US Department of Justice, the stolen trade secrets were related to technologies used to detect nuclear missile launches, track ballistic and hypersonic missiles, and allow U.S. fighter planes to detect and evade heat-seeking missiles.

Chenguang Gong, 59, of San Jose, pleaded guilty to one count of theft of trade secrets.

He remains free on $1.75 million bond.

According to his plea agreement, Gong – a dual citizen of the United States and China – transferred more than 3,600 files from a Los Angeles-area research and development company where he worked – identified in court documents as the victim company – to personal storage devices during his brief tenure with the company last year.

The files Gong transferred include blueprints for sophisticated infrared sensors designed for use in space-based systems to detect nuclear missile launches and track ballistic and hypersonic missiles, as well as blueprints for sensors designed to enable U.S. military aircraft to detect incoming heat-seeking missiles and take countermeasures, including by jamming the missiles’ infrared tracking ability. Some of these files were later found on storage devices seized from Gong’s temporary residence in Thousand Oaks.

In January 2023, the victim company hired Gong as an application-specific integrated circuit design manager responsible for the design, development and verification of its infrared sensors.

 Beginning on approximately March 30, 2023, and continuing until his termination on April 26, 2023, Gong transferred thousands of files from his work laptop to three personal storage devices, including more than 1,800 files after he had accepted a job at one of the victim company’s main competitors, read a statement issued by the US State Department.

Many of the files Gong transferred contained proprietary and trade secret information related to the development and design of a readout integrated circuit that allows space-based systems to detect missile launches and track ballistic and hypersonic missiles and a readout integrated circuit that allows aircraft to track incoming threats in low visibility environments.

Gong also transferred files containing trade secrets relating to the development of “next generation” sensors capable of detecting low observable targets while demonstrating increased survivability in space, as well as the blueprints for the mechanical assemblies used to house and cryogenically cool the victim company’s sensors, the US Department of Justice said.

Law enforcement also discovered that, between approximately 2014 and 2022, while employed at several major technology companies in the United States, Gong submitted numerous applications to ‘Talent Programs’ administered by the People’s Republic of China (PRC).

The PRC government has established these talent programs as a means to identify individuals who have expert skills, abilities, and knowledge of advanced sciences and technologies in order to access and utilize those skills and knowledge in transforming the PRC’s economy, including its military capabilities.

According to his plea agreement, the intended economic loss from Gong’s criminal conduct exceeds $3.5 million.

U.S. District Judge John F. Walter scheduled sentencing for Sept. 29, at which time Gong faces a statutory maximum penalty of 10 years in prison.
