Alternate Title: NSDM 340: U.S. Port Security Program
In National Security Decision Memorandum (NSDM) 340 President Ford "has approved the following statement of policy on U.S. port security, which supersedes National Security Decision Memorandum No. 82 dated September 1, 1970, and previous issuances of national security statements on this subject. 1) National security interests require that measures be taken for the protection of vessels, harbors, ports and waterfront facilities of the United States from threats of espionage, sabotage, intelligence collection operations directed against sensitive U.S. defense facilities from foreign vessels, and related subversive activities including the introduction into the United States of persons or materials in the pursuance of such activities. It is also in our national interests that entries of vessels of certain nations, as specified below, into U.S. ports be permitted only in reciprocity for the admission of U.S. vessels to ports of those countries or in reciprocity for other considerations."
