The Cape Canaveral Light is a historic lighthouse on the east coast of the U.S. state of Florida. The light was established in 1848 to warn ships of the dangerous shoals that lie off its coast. It is located inside the Cape Canaveral Air Force Station and managed by the 45th Space Wing of the U.S. Air Force with the assistance of the Cape Canaveral Lighthouse Foundation. It is the only fully operational lighthouse that is owned by the United States Air Force. The current lighthouse tower was first erected and lit in 1868 then relocated further inland between 1893-1894. It was originally equipped with a first-order Fresnel lens that was automated in 1967 and then retired from the tower in 1993. ==History== The Cape Canaveral lighthouse was erected to warn mariners of the outlying shoals off its coast. Broken ground and shoals extend northward and northeastward of the lighthouse terminating in the Hetzel and Ohio shoals, which have a depth of and respectively. Hetzel Shoal is located about NE of the lighthouse and Ohio Shoals about southward of Hetzel. In a heavy sea these shoals are marked by breakers, but with smooth sea there is nothing to indicate their locality.〔United States Coast and Geodetic Survey (1922). ("U.S. Coast Pilot: Atlantic Coast Section D" ), pg. 122. Government Printing Office, Washington.〕 The land is usually not visible from off these outer shoals. Located closer to the land are the Chester, Bull and Southeast shoals, which are about off the coast of the cape.〔〔United States Coast and Geodetic Survey (1900).
