This section contains a codification of functions. It sets forth in general language the primary responsibilities of the Coast Guard: enforcement of all Federal laws on waters to which they have application, safety of life and property at sea, aiding navigation, and readiness to function with the Navy. Having been created in 1915 by the consolidation of the Revenue Cutter Service and the Life Saving Service, the Coast Guard has gradually been given additional duties and responsibilities, such as the assignment of law enforcement powers on the high seas and navigable waters in 1936, the transfer of the Lighthouse Service in 1939, and the transfer of the Bureau of Marine Inspection and Navigation in 1942. Existing along with these other duties has been that of maintaining a state of readiness as a specialized service prepared for active participation with the Navy in time of war. These various interdependent functions of the Service have not been expressed collectively in any statute heretofore, but it is believed desirable to do so in this revision in order to have outlined in general terms in one section the broad scope of the functions of the Coast Guard. 81st Congress, House Report No. 557.
