A naturalized U.S. citizen from China who worked for 10 years for a Raytheon Corporation subsidiary as an electrical engineer has pleaded guilty to a federal arms exportation charge.
Wei Sun pleaded guilty Friday in U.S. District Court in Tucson, where Raytheon Missile Systems has a large defense plant that produces missiles.
In a plea agreement with prosecutors, the 48-year-old Sun acknowledged taking a Raytheon laptop to China on a 2018 personal trip and acknowledged that it contained sensitive missile material.
An indictment charging Sun did not allege he actually shared any of the information but merely taking sensitive weapons files out of the country without permission violates federal law on arms exports.
Sentencing was set for April 28.
