Convicted felon charged with illegal export of rocket technology to South Korea

FORT LAUDERDALE, Fla. - A New Jersey resident, Juwan Yun, a/k/a "Jw Yun," 69, was arrested and charged with attempting to export and exporting RD-180 rocket propulsion system and technology to the Republic of South Korea without a license as a result of a U.S. Immigration and Customs Enforcement (ICE) investigation with the U.S. Department of Defense (DOD) and NASA Office of the Inspector General (OIG).

Yun was arrested by ICE special agents in Fort Lauderdale and charged in a six-count indictment with attempting to export defense articles without a license and brokering defense articles designated on the U.S. Munitions List (USML) and the Missile Technology Control Regime Annex, without first having registered and obtained a license from the U.S. Department of State, Directorate of Defense Trade Controls, in violation of the Arms Export Control Act (AECA), the Missile Technology Control Regime, and the International Trafficking in Arms Regulations (ITAR). If convicted of all charges, Yun faces up to 60 years in prison.

The indictment alleges that as early as December 2008, Yun tried to acquire RD 180 rocket propulsion systems, engines and related technology for subsequent sale and delivery to the Republic of South Korea. These items are classified as defense articles under the USML.

According to an affidavit previously filed with the court in support of the criminal complaint, Yun was previously convicted of a conspiracy to export Sarin gas, in violation of the Arms Export Control Act and was sentenced to 39 months in prison. As a result of this conviction, Yun was debarred by the Department of State, Directorate of Defense Trade Controls and is prohibited from engaging in any export or brokering activities involving defense articles.

U.S. Attorney R. Alexander Acosta commended the investigative efforts of ICE's Office of Investigations, DOD's Defense Criminal Investigative Service, and NASA OIG's Office of Criminal Investigations.
