Which agency is primarily responsible for maritime security assessments?

The U.S. Coast Guard is the primary agency responsible for maritime security assessments, as it plays a crucial role in maintaining the safety and security of American waterways and ports. This encompasses a variety of activities, including monitoring and enforcing laws related to maritime security, conducting security assessments to identify vulnerabilities, and implementing strategies to mitigate risks. The Coast Guard is tasked with safeguarding the nation's maritime interests against threats such as terrorism, smuggling, and other illegal activities.

The agency's expertise in marine operations and law enforcement makes it uniquely qualified to assess security needs in the maritime domain. This includes collaborating with other federal, state, and local agencies to develop comprehensive maritime security plans, conduct inspections, and ensure compliance with security regulations established under legislation such as the Maritime Transportation Security Act.

While the other agencies listed have specific roles related to transportation, environmental protection, and maritime administration, they do not possess the comprehensive mandate and operational capabilities that the Coast Guard has in assessing and managing maritime security.
