There are mistakes. There are lapses in judgment.

And then there is this.

A former United States Air Force fighter pilot — trained by America, trusted with its most advanced military capabilities — now stands accused of teaching Chinese military pilots how to fight against the very country he once swore to protect.

Gerald Eddie Brown Jr., call sign “Runner,” was arrested Wednesday in Jeffersonville, Indiana. Federal prosecutors say he provided — and conspired to provide — combat aircraft training to pilots in the Chinese Air Force, formally known as the People’s Liberation Army Air Force (PLAAF).

Here’s the FBI announcement detailing the arrest:

There is a word for this kind of betrayal.

The charge? Violating the Arms Export Control Act — a federal law that strictly regulates the export of U.S. defense services and military technology. The law requires government approval before Americans can share such expertise with foreign governments or nationals.

According to the Department of Justice, Brown is accused of providing and conspiring to provide defense services to Chinese military pilots without authorization.

“The United States Air Force trained Major Brown to be an elite fighter pilot and entrusted him with the defense of our Nation. He now stands charged with training Chinese military pilots,” Assistant Attorney General for National Security John A. Eisenberg said. “When U.S. persons – whether military or civilian – provide training to a foreign military, that activity is illegal unless they have a license from the State Department.”

Prosecutors allege that since “at least in or around August 2023,” Brown “willfully conspired” with foreign nationals and other U.S. persons to provide combat aircraft training to PRC pilots.

Brown served more than 24 years in the U.S. Air Force and left active duty in 1996 with the rank of major. He wasn’t a rookie. He was a former F-35 Lightning II instructor pilot with decades of experience flying U.S. military aircraft.

And yet, according to the criminal complaint, around August 2023 Brown used a co-conspirator to negotiate a contract with a Chinese national to train military pilots for the People’s Republic of China.

That Chinese national? Stephen Su Bin — who previously pled guilty to conspiring to steal sensitive U.S. military data from defense contractors. His company had been listed by the U.S. government as a known entity of the Chinese government.

Throughout negotiations, prosecutors say Brown “consistently stated his intent to train PRC military pilots in combat aircraft operations.”

“Now…. I have the chance to fly and instruct fighter pilots again!” Brown allegedly wrote in a message to his co-conspirator when he arrived in China in December 2023.

He remained in China until returning to the U.S. in early February 2026 — where he was promptly arrested.

Here’s his mugshot:

FBI officials didn’t mince words.

“Gerald Brown, a former F-35 Lightning II instructor pilot with decades of experience flying US military aircraft, allegedly betrayed his country by training Chinese pilots to fight against those he swore to protect,” said Roman Rozhavsky, assistant director of the FBI’s Counterintelligence and Espionage Division.

Rozhavsky warned, “The Chinese government continues to exploit the expertise of current and former members of the US armed forces to modernize China’s military capabilities. This arrest serves as a warning that the FBI and our partners will stop at nothing to hold accountable anyone who collaborates with our adversaries to harm our service members and jeopardize our national security.”

U.S. Attorney for the District of Columbia Jeanine Pirro added that Brown “betrayed the country” and “jeopardized the safety of our servicemembers and allies.”

The implications are staggering.

America invested decades into training this pilot. The knowledge he carried wasn’t theoretical — it was tactical. Real-world combat experience. Advanced aircraft maneuvering. Operational strategy.

And prosecutors say he handed it to Beijing.

If the allegations are proven true, this isn’t just a violation of export law. It’s a betrayal that could cost lives.

The question now isn’t whether this case is serious.

It’s how many more adversaries are trying to buy the expertise America spent decades building — and who else might be willing to sell it.
