Former US F-35 fighter pilot arrested for training Chinese air force 

A former United States Air Force officer and “elite fighter pilot” has been arrested and accused of betraying his country for illegally providing training to Chinese military pilots.

The US Department of Justice said ex-Air Force Major Gerald Brown, once known by his pilot’s call sign “Runner”, was arrested on Wednesday in Indiana and charged with a criminal complaint for providing and conspiring to provide defence services to Chinese pilots without authorisation.

Brown, 65, a former F-35 Lightning II instructor pilot with decades of experience in the Air Force, “allegedly betrayed his country by training Chinese pilots to fight against those he swore to protect”, Roman Rozhavsky, assistant director at the FBI’s Counterintelligence and Espionage Division, said in a statement.

“The Chinese government continues to exploit the expertise of current and former members of the US armed forces to modernise China’s military capabilities. This arrest serves as a warning,” Rozhavsky said.

US Attorney Jeanine Ferris Pirro for the District of Columbia said Brown “and anyone conspiring against our Nation” will be held accountable for their actions.

According to the Justice Department, Brown served in the US Air Force for 24 years, had led combat missions and was responsible for commanding “sensitive units”, including those involved in nuclear weapons delivery systems.

After leaving the US military in 1996, Brown worked as a commercial cargo pilot before working as a defence contractor training US pilots to fly F-35 and A-10 warplanes.

Brown is alleged to have travelled to China in December 2023 to begin his work training Chinese pilots, and he remained in the country until returning to the US in early February 2026.

His contract to train Chinese pilots was negotiated by Stephen Su Bin, a Chinese national who in 2016 pleaded guilty and was sentenced to four years in prison for conspiring to hack a defence contractor in the US to steal military secrets for China, according to the Justice Department.

The department said Brown faces charges similar to those levelled against former US Marine Corps pilot Daniel Duggan, who was arrested in Australia in 2022 and is currently fighting his extradition back to the US, where he faces prosecution for violating the US Arms Export Control Act for providing pilot training to the Chinese armed forces.

Duggan appeared in an Australian court in October 2025 to appeal against his extradition, which was approved in December 2024 by Australia’s then Attorney General Mark Dreyfus.

Duggan, 57, a naturalised Australian citizen, was arrested by Australian police in 2022 shortly after returning from China, where he had lived since 2014.

According to the Reuters news agency. Duggan’s lawyer, Christopher Parkin, told the court that his client’s extradition to the US was “uncharted territory” for Australia.

He argued that his client’s conduct was not an offence in Australia at the time or when the US requested extradition, and so did not meet the requirement for dual criminality in Australia’s extradition treaty with the US.

The governments of Australia, Canada, New Zealand, the United Kingdom and the US published a notice in 2024 warning current and former members of their armed forces that China was seeking to recruit them and other NATO military personnel in order to harness Western military expertise and bolster its own capabilities.

“The insight the PLA [People’s Liberation Army] gains from Western military talent threatens the safety of the targeted recruits, their fellow service members, and US and allied security,” the notice stated.

“Those providing unauthorized training or expertise services to a foreign military can face civil and criminal penalties,” it added.
