Book excerpt: Seabees and Superforts begins by describing the miracle of construction by the 6th Naval Construction Brigade, building the airfields, roads, and harbor necessary to land and support 400 B-29s for the air campaign against Japan. It then tells the story of how those B-29s were used to bomb Japan and aerial mining to blockade Japan's harbors. It ends with the story of the Manhattan Project on Tinian, receiving, assembling, and delivering the bombs to Hiroshima and Nagasaki.
