WASHINGTON — A nuclear engineer for the U.S. Navy and his wife have been charged with trying to share some of the United States’ most closely held techniques on submarine technology with a different state, according to court files unsealed on Sunday.

The engineer, Jonathan Toebbe, was accused of attempting to market facts on the nuclear propulsion program of U.S. Virginia-course attack submarines — the technologies at the coronary heart of a not long ago announced offer with Britain and Australia.

Nuclear propulsion is amongst the most carefully held info by the U.S. Navy for the reason that the reactors are fueled by remarkably enriched uranium, which can also be converted to bomb fuel for nuclear weapons. Making compact, protected naval reactors is also a challenging engineering process. Right until the offer with Australia, the United States experienced shared the technologies with only Britain, starting off in 1958.

According to the court paperwork, the investigation into the Toebbes began in December 2020, when the F.B.I. obtained a bundle that experienced been sent to yet another country with operational manuals, specialized details and an give to build a covert romantic relationship.

Brokers then set up another dead fall in Pennsylvania and a third in Virginia, in which they claimed Mr. Toebbe deposited an SD card concealed in a package of chewing gum.

Whilst functioning at the Bettis Atomic Power Laboratory, a small-recognised government research facility in West Mifflin, Pa., Mr. Toebbe would have experienced accessibility to the documents that he is accused of passing to the undercover F.B.I. officer.

A lot of of the details of the exchanges had been redacted in the court docket documents, but there was a reference to scaled drawings and servicing aspects.
