Silicon Valley engineer admits theft of US missile tech secrets

A San Jose engineer, Chenguang Gong, pleaded guilty to downloading more than 3,600 files containing trade secrets—including infrared countermeasure sensor designs and radiation-hardened space camera schematics—from his employers and storing them on personal USB and external drives; the documents are valued in the hundreds of millions and the theft raised national security concerns because of ties to Chinese talent programs and potential transfer to a foreign government, leading to FBI investigation and criminal charges.
