CNWDI stands for "Critical Nuclear Weapons Design Information." It is a classification level used in the United States to protect highly sensitive information and technical data regarding the design, testing, and maintenance of nuclear weapons.
CNWDI is the highest level of classification within the Nuclear Weapons Security program, and its primary purpose is to prevent unauthorized access and dissemination of information that could potentially compromise the security and integrity of the nation's nuclear weapons systems.
Under CNWDI classification, information related to the physics, engineering, specifications, performance characteristics, and operational procedures of nuclear weapons is considered highly confidential. This includes data on the design and construction of fissile materials, explosive components, and other critical systems within a nuclear weapon.
Access to CNWDI information is restricted to a select group of individuals who have been granted the appropriate security clearance and possess a "need-to-know" the information for their authorized duties. Stringent security measures, including physical access controls and robust cybersecurity protocols, are put in place to safeguard CNWDI materials from unauthorized disclosure.
The CNWDI classification plays a vital role in ensuring the safety, security, and effectiveness of the United States' nuclear arsenal. It is instrumental in preventing proliferation and maintaining a deterrent capability against potential adversaries, as well as protecting the knowledge and expertise of nuclear weapons development from falling into the wrong hands.
