History of the Coast Guard

The Coast Guard has changed names several times over its 200+ year history, but it is largely the same organization as it was in 1790 as the Revenue Marine. Uniforms, culture, and professions are very similar to the Navy, but the mission is different. While the Navy ensures freedom of navigation internationally, the Coast Guard does so for our nation's coasts through vessel inspections, law enforcement, drug and migrant interdiction, maintenance of navigation aids, environmental protection and research, ice operations, and search-and-rescue. Sailors of the Navy and Coast Guard have a high respect for each other, knowing that one can do what the other cannot.
