What is the term for a Department of Defense category of TOP SECRET Restricted Data or SECRET Restricted Data that reveals the theory of operation or design of components of a thermonuclear or fission bomb, warhead, demolition munition, or test device?

• A. Critical Nuclear Weapon Design Information (CNWDI)
• B. Critical Program Information (CPI)
• C. Critical Technology
• D. Cybersecurity

Answer: (A)

This term specifically names a narrowly defined security category for information about nuclear weapons. Critical Nuclear Weapon Design Information covers the theory of operation and the design details of components inside thermonuclear or fission bombs, warheads, demolition munitions, or test devices. Because revealing this level of detailed design could directly enable the construction or enhancement of nuclear weapons, it is safeguarded at TOP SECRET Restricted Data or SECRET Restricted Data levels and subject to strict handling and access controls.

The other terms do not fit this precise scope. Critical Program Information refers to sensitive details about a weapons program's vulnerabilities or key aspects of its execution, not the essential design details of the weapons themselves. Critical Technology is a broader label used to flag important technologies but not specifically tied to nuclear weapon design information. Cybersecurity focuses on protecting information systems and does not pertain to the design theory or components of nuclear weapons.
