Virginia Class Submarine
Half of a peanut butter sandwich in a plastic bag was left at an agreed location in West Virginia by a Navy nuclear engineer. Inside the sandwich, wrapped in plastic, was a 16 GB memory card containing detailed secret information about the US Navy’s Virginia-class submarine reactors. In subsequent drops, more memory cards containing submarine secrets were left in a bandaid box and a chewing gum container at sites in Pennsylvania and Virginia.
The engineer, Jonathan Toebbe, and his wife, Diana Toebbe, thought that they were giving the information to a foreign country in exchange for cryptocurrency payments. Instead, the FBI had intercepted their correspondence and impersonated foreign agents.
