Florida man convicted on all 12 counts in $1 million Russia export scheme

A Florida resident and Russian national was convicted on all 12 counts in a scheme to illegally export nearly $1 million in aircraft parts to Russia and its state-owned airline, according to the Department of Justice.

Alexander Mamonov, 62, was found guilty by a federal jury in the Southern District of Florida, the DOJ said. The charges included conspiracy to violate the Export Control Reform Act, illegal export of controlled items, conspiracy to commit smuggling, smuggling of goods, submitting false export information, and conspiracy to commit money laundering, according to the department.

“This guilty verdict – on all counts – shows the United States government’s resolute commitment to upholding our export-control laws and to prosecuting those who violate them,” Assistant Attorney General for National Security John A. Eisenberg said, according to the DOJ.

FBI Counterintelligence and Espionage Division Assistant Director Roman Rozhavsky said Mamonov lied to U.S. suppliers about the destination of the parts, and called the conviction a warning to others who might attempt to smuggle American technology to adversaries, according to the FBI.

U.S. Attorney Jason A. Reding Quiñones for the Southern District of Florida said the defendant used false shipping destinations and financial transactions to try to circumvent U.S. sanctions and export controls, and vowed continued prosecution of those who use the district or U.S. financial systems to threaten national security, according to his office.

U.S. District Court Judge Kathleen M. Williams has scheduled sentencing for Nov. 20, the DOJ said.

Mamonov was charged by indictment in April 2025 alongside Ignat Vakorin of Russia, who remains a fugitive, according to the department.

According to court documents and testimony cited by the DOJ, Mamonov is a former Aeroflot employee who relocated from Russia to South Florida. After Russia’s 2022 invasion of Ukraine prompted the Commerce Department to tighten export restrictions and bar Aeroflot from receiving U.S.-origin goods, Mamonov conspired with Vakorin to acquire and ship more than $900,000 in aircraft parts to Russia and Aeroflot, misleading suppliers into believing the parts were headed to the United Arab Emirates and China, the DOJ said.

The case was investigated by the FBI’s Miami Field Office with assistance from the Commerce Department’s Bureau of Industry and Security, according to the department. Assistant U.S. Attorney Sean Paul Cronin and National Security Division Trial Attorney Brett Ruff are prosecuting the case, the DOJ said.
