WASHINGTON — A nuclear engineer for the U.S. Navy and his spouse have been charged with making an attempt to share a number of the United States’ most intently held secrets and techniques on submarine expertise with one other nation, in accordance to courtroom paperwork unsealed on Sunday.
The engineer, Jonathan Toebbe, was accused of making an attempt to promote info on the nuclear propulsion system of U.S. Virginia-class assault submarines — the expertise on the coronary heart of a not too long ago introduced take care of Britain and Australia.

While working on the Bettis Atomic Power Laboratory, a little-known authorities analysis facility in West Mifflin, Pa., Mr. Toebbe would have had entry to the paperwork that he’s accused of passing to the undercover F.B.I. officer.
Many of the main points of the exchanges had been redacted in the courtroom paperwork, however there was a reference to scaled drawings and upkeep particulars.
