July 28, 1975: US Congress Approves Ugrade of Diego Garcia Base
US Congress passes a bill allowing the Department of Defense to upgrade the communications facility at Diego Garcia to a “naval support” base. The US will lengthen the island’s runway from 8,000 to 12,000 feet, increase the available petroleum, oils, and lubricants storage, and dredge its harbor, among other improvements.
