USS Langley (CVL-1919-22 (1910))
Once the advent of the aircraft carrier type ships came into the navies of the
world, the different types of ships that could be used as the basis for ships to
carry aircraft were ready to be explored. It was known to the US Navy of the
experiments of the Royal Navy with various sized ships being converted,
battleships, cruisers, ex-liners and merchant ships. Where the Royal Navy had
plenty of ships that could be converted, the US Navy did not have the same
quantity of ships under construction they could choose from. Looking through the
inventory of available vessels, the two Memphis class cruisers, with the Pacific
Fleet, could be used as the US Navies first foray into the world of naval
aviation. Sent to Pacific coast yards, the two ships were to be converted to
aircraft carriers.
The conversion of the two ships Langley and Missoula was carried out in
different phases. First phase was to fit just a flight deck on the ships so that
trials with wheeled aircraft could be carried out and shown to be effective to
those who counted. Second phase was to strip the ship from bow to stern fit a
hangar for storing the aircraft to be carried in. Refitting the flight deck at
the new higher level. Fitting the new funnel arrangement with the new bridge
superstructure forward of them. Next was the reworking of the bow so that
spray would deflect away from the aircraft taking off. The fitting of the
armament (which changed regularly over the next 20 years).
Further improvements to the ships were made on a regular basis as new equipment was
thought of, designed and built. Arrestor wires, catapults, all were added as
they came into service.
