John Murray Rowe, a 67-year-old former defense contractor from South Dakota, has been sentenced to 10 years and 6 months in prison for attempting to disclose classified information about U.S. Air Force systems to the Russian government.

According to the Department of Justice, Rowe pleaded guilty to one count of attempted delivery of national defense information to a foreign government and three counts of willful communication of national defense information. The sentence also includes three years of supervised release and a $25,000 fine.

Rowe, who held various security clearances during his nearly four-decade career as a test engineer, was terminated from his position after exhibiting what officials described as “concerning inquiries and statements about Russia and sensitive information.” This development follows earlier reports that Rowe had committed several security violations.

In March 2020, Rowe initiated contact with an individual he believed to be a Russian agent—in fact, an undercover FBI operative. Reports indicate that during this meeting, Rowe disclosed classified information about electronic countermeasure systems used by U.S. military fighter jets.

This case raises important questions about the vulnerability of classified information and the effectiveness of security protocols within defense contracting firms. The evidence suggests that over eight months, Rowe exchanged more than 300 emails with the purported Russian agent, demonstrating a willingness to work against U.S. interests.

While the defense may point to Rowe’s long service and potential personal grievances, prosecutors emphasize the deliberate and repeated nature of his actions. Assistant Attorney General John A. Eisenberg stated, “The Justice Department will hold accountable those who disregard country and conscience at the expense of our Nation’s security.”

This situation underscores the ongoing challenges faced by U.S. counterintelligence efforts. FBI Assistant Director Roman Rozhavsky noted the Bureau’s commitment to bringing such cases to justice, saying, “Anyone tempted to violate their oath to safeguard classified information should understand the severe consequences.”
