MIAMI, Oct. 20 (UPI) -- A South Korean-born businessman was sentenced Wednesday to 57 months in federal prison for illegally exporting rocket technology to his homeland.
Juwhan Yun pleaded guilty in May to acting as an arms broker for the Republic of Korea without the required license from the U.S. State Department. He was debarred from acting as an arms broker or exporter because of a 1989 conviction for conspiracy to export Sarin, a deadly nerve gas.
A federal judge in Miami also imposed three years supervised release after Yun completes his term.
The arms Yun allegedly exported included a 20mm gun, the M61Vulcan; Russian air defense systems and components; and parts for the SU-27 Russian fighter aircraft.
Before his 1989 conviction and sentence to 39 months in prison, Yun ran an arms exporting business, Komex International, in Newark, N.J., that did most of its legitimate business with South Korea. He was convicted of negotiating with an undercover agent to procure Sarin for Charles Caplan, a London-based exporter with a reputation for dealing with Iran and Libya.
