Sea Frontier
Sea Frontiers were established by the United States Navy from 1 July 1941 during World War II as areas of defense against enemy vessels, especially submarines, along the American coasts. Sea Frontiers generally started at the shore of the United States and extended outwards into the sea for a nominal distance of two hundred miles.
The commander of a Sea Frontier had control and responsibility for convoys within its defined area, had its own vessels for convoy use or other uses as determined by the commander, and worked closely with the U.S. Army Air Force in the defense of the frontier. Usually, offices of the U.S. Navy and U.S. Army Air Force officers assigned to the frontier, had their offices side by side in order to create effective two-way communications and expedited reaction to reports of enemy presence.
In addition to providing escorts for convoys within its frontier, the frontier was responsible for sea-air rescue, harbor defense, shipping lane patrol, minesweeping, and air operations.
Sea Frontiers were intended for wartime use, but many continued on for some years after the end of World War II.
In addition to the Sea Frontiers under the cognizance of U.S. military authorities, the Canadian Coastal Zone was the responsibility of the Royal Canadian Navy. This formation was very active since the majority of trans-Atlantic convoys originated or terminated in Canadian waters.
