USS Langley (CV-1) with Vought VE-7 aircraft on deck. In the background are 4 four-stack destroyers and a Tennessee-class battleship on the left and two New Mexico-class battleships (center and right). The original photo was labeled "Harbinger" to show symbolically how the unimposing Langley was the first of a line of ships which eventually drove the battleship from its primary place into the background. Circa 1923.
