Alternate Title: NSD 57: U.S. Port Security Program
In National Security Directive (NSD) 57, President H.W. Bush directs that "measures be taken to control the access of foreign flag vessels to U.S. ports and internal waters. The objectives of this control are as follows: 1. Protect U.S. vessels, ports, harbors, and waterfront facilities from sabotage or other activities intended to hazard their safety. 2. Protect sensitive operations and U.S. defense facilities in waterfront areas from espionage and intelligence collection. 3. Protect U.S. national interests defined in terms of foreign policy considerations: Examples would include limiting port access for countries that sponsor international terrorism or as a reciprocal response to limitations in access for U.S. vessels. 4. Protect the exercise of U.S. maritime rights and high seas freedoms from international interference by specific vessels."
