<P> Naval Nuclear Propulsion Information (NNPI) is a category of intellectual capital defined by the United States Navy to be "classified or unclassified information concerning the design, arrangement, development, manufacture, testing, operation, administration, training, maintenance, and repair of the propulsion plants of naval nuclear - powered ships and prototypes, including the associated shipboard and shore - based nuclear support facilities ..." </P> <P> Not all NNPI is classified information . 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 carried out by the Navy can be useful to industry . Unclassified information is therefore marked with the acronym "U-NNPI", but is still restricted as NOFORN . </P>
