A California woman has been sentenced to more than four years in federal prison for illegally exporting U.S. military gear to China including jet fighter engines and a drone aircraft.

Court records show a Miami federal judge imposed the sentence Friday on 45-year-old Wenxia Man of San Diego. A jury convicted her in June of conspiring to export and actually exporting military equipment without the proper license.

Federal prosecutors say evidence in the case showed Man worked with a person in China to export engines used in F-135, F-22 and F-16 fighter jets as well as an MQ-9 Reaper drone aircraft capable of firing Hellfire missiles.

Man allegedly told an undercover Homeland Security Investigations agent she worked with a spy who helped the Chinese military copy items from other countries.
