The United States has arrested a retired Air Force pilot accused of providing unauthorized training to Chinese military members. According to a statement from the US Department of Justice, 65-year-old Gerald Brown was detained in Indiana after returning from China, where he had been staying since December 2023. Authorities allege that Brown conspired with foreign nationals to train Chinese Air Force pilots in operating combat aircraft without the required State Department license.

Brown served 24 years in the US Air Force, leading sensitive nuclear weapons units, flying combat missions, and working as a fighter pilot and simulator instructor. After retiring in 1996, he worked as a cargo pilot and later as a defense contractor, training pilots on A-10 and F-35 aircraft. Investigators say he began discussions in August 2023 with Chinese citizen Stephen Su Bin, who previously served a prison sentence in the US for espionage, before traveling to China to begin training in December.

An FBI counterintelligence official said the arrest serves as a warning that the agency will hold accountable anyone who collaborates with adversaries to endanger US national security.
