A bill to amend title 18, United States Code, to provide the death penalty for civilian espionage.

Amends the Federal criminal code to provide the death penalty for civilian espionage that directly concerns specified weaponry or communication systems or information. States that no person may be sentenced to death under this Act unless the jury (or judge if the accused waives a jury) finds (in a separate sentencing proceeding): (1) at least one aggravating factor to exist; and (2) that any extenuating or mitigating circumstances are substantially outweighed by aggravating circumstances. Sets forth the aggravating factors to be considered, including the knowing endangerment of national security.
