USS LANGLEY (CV-1) under reconstruction from the collier, USS JUPITER (AC-3), at Norfolk Navy Yard, Portsmouth, Virginia. She was the first US Navy ship built with turbo electric transmission propulsion. This system used steam to power a turbine connected to an electrical generator, to power the propeller motors and everything else on the ship. This allowed for greater fuel efficiency and had greater redundancies.
Note: boat storage yard ashore, and USS GEORGE E. BADGER (DD-196) in background.
Date: late 1921
