A US Navy nuclear engineer with access to military secrets has been charged with trying to pass information about the design of American nuclear-powered submarines to someone he thought was a representative of a foreign government but who turned out to be an undercover FBI agent, the Justice Department said on Sunday.

In a criminal complaint detailing espionage-related charges against Jonathan Toebbe, the government said he sold information for nearly the past year to a contact he believed represented a foreign power. That country was not named in the court documents.

Toebbe, 42, was arrested in West Virginia on Saturday along with his wife, Diana, 45, after he had placed a removable memory card at a prearranged “dead drop” in the state, according to the Justice Department.

The Federal Bureau of Investigation says the scheme began in April 2020 when Jonathan Toebbe sent a package of US Navy documents to a foreign government and wrote that he was interested in selling to that country operations manuals, performance reports and other sensitive information.

Authorities say he also provided instructions for how to conduct the furtive relationship, with a letter that said: “I apologise for this poor translation into your language. Please forward this letter to your military intelligence agency. I believe this information will be of great value to your nation. This is not a hoax.”
