Naval Nuclear Propulsion Information is a category of intellectual capital defined by the United States Navy to be "that information and/or hardware concerning the design, arrangement, development, manufacturing, testing, operation, administration, training, maintenance, and repair of the propulsion plants of Naval Nuclear Powered Ships including the associated shipboard and shore-based nuclear support facilities." It is not a classification category; while most NNPI is sensitive, the Navy recognizes that the public has an interest in environmental, safety, and health information, and that the basic research the Navy carries out can be useful to industry.
