"Maritime Commerce Security Plan establishes a comprehensive plan to secure the maritime supply chain. The Maritime Commerce Security Plan was developed in conjunction with the other component plans of the National Strategy for Maritime Security. In particular, the development of the Maritime Transportation System Security Plan and the Maritime Infrastructure Recovery Plan was closely coordinated with this plan. The Maritime Transportation System Security Plan addresses the security of the maritime transportation system as a system including vessels, facilities and ports that contribute so greatly to cargo security and, in this way, complements this plan."
