CV-1 was named after Samuel Pierpont Langley (1834-1906). Born in Roxbury, Mass., he became a distinguished American astronomer, physicist, and pioneer in the development of heavier-than-air craft. In 1865 he was assistant in the Harvard Observatory, and the following year an assistant professor of mathematics at the Naval Academy. In 1878, as director of the Allegheny Observatory, he devised the bolometer—a radiant-heat detector that is sensitive to differences in temperature of one hundred-thousandth of a degree Celsius (0.00001 C)—and other scientific apparatus. In 1881 he organized a successful expedition to Mount Whitney, Calif. Professor Langley was honored by degrees from Oxford, Cambridge, Princeton, Yale, among other universities. He died in Aiken, S.C.

At Norfolk Navy Yard during the conversion process, 9 May 1921. An extra deck called the Superstructure Deck has been added on top of the Poop Deck aft for officer's accomodation. The original derricks have been replaced with towers to support the flight deck. The funnel has been relocated to a sponson on the portside.

Landing aboard Langley.

Bradley Ingram comments:

"I think I have identified one of the aircraft on the page for the USS Langley (CV-1). I believe that NS020140 is a Loening OL-4 observation aircraft. Based on the style of exhausts, it could be an OL-2, OL-4 or an OL-6, from the shape of the cutouts under the engine, it could be an OL-4, or an OL-6, and from the shape of the wing floats, I think that the aircraft shown is an OL-4."

"According to American Combat Planes by Ray Wagner, the first of the six OL-4s were delivered to the Navy in April 1926, which gives an early cutoff date for when the photo was taken. Unfortunately, I don't have any better information to date the photograph."

At anchor, crew manning the rail.

Darren Large notes: "Gonaives, Haiti, March–April 1927. Foremost plane is a Douglas T2D-1."

The single engine, two-crew land biplane was built by Chance-Vought for Army use. The Navy adopted the plane and it was the first aircraft to fly off an aircraft carrier.

Darren Large, however, believes this is a Martin MO-1 observation plane recovering aboard, probably off San Diego, circa 1925.

Other aircraft are Vought VE-7s of Fighting Squadron Two (VF-2), including Bureau #s A5936 (marked "2-F-9") and A5938 (marked "2-F-8"). The ship's boats are stowed along the hangar sides.

USS Langley (CV-1) in a view taken while at North Island, San Diego, California, in 1924. Note mast on flight deck, just forward of the two funnels on the port side. Also note USS Ortolan (AM-45) in background, alongside the pier visible just above Langley's mast. The similar type ship just ahead of Ortolan appears to be attached to an aviation unit, as indicated by the barely-visible star insignia on the bow.

Darren Large notes: "The absence of the three portholes on the funnel sponson means this is circa 1925."

USS Langley (CV-1) barely underway in calm waters, January 1925, location unknown (somewhere in the Pacific), with a Vought VE-7 about to land amidst a flock of birds.

A safety net is rigged aft, below flight-deck level, and the funnels are lowered. The calm waters and the fact the carrier is making little way suggest a negligible wind-over-deck; however, the flight deck presents no obstacles for the pilot to be wary of.

USS Langley (CV-1) docked at the carrier pier at Naval Air Station, North Island, San Diego, California, with a Douglas DT-2 airplane taking off from her flight deck. This photo may have been taken during catapult tests in 1925.

Believed to have been taken at Pearl Harbor.

Closeup of view above. Her bridge, unaltered since her days as a collier, can be seen forward, below the flight deck and just aft of one of her 5" guns.

Darren Large comments: "[This is] [i]n either 1925 or 1926 because her first posting in Pearl was April through September 1925. In Jan 1927 at Mare Island, the Disbursing Office was fitted to where the original starboard side exhaust vent was. As this is absent in the photo, it is probably 1925, possibly early 1926."

USS Langley underway, circa 1926.

USS Langley (CV-1) with Vought VE-7 aircraft on deck, at anchor off Culebra Island, Puerto Rico, on 18 March 1926. In the background are 4 four-stack destroyers and a Tennessee (BB-43/44)-class battleship on the left, and two New Mexico (BB-40/42)-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.

Ships of the U.S. Fleet pictured at anchor at Guantanamo Bay, Cuba, during winter exercises in 1927 (Fleet Problem VII, March 1927?).

The "center" row has Mississippi (BB-41), then Langley (CV-1), Oklahoma (BB-37), Pennsylvania (BB-38) and Arizona (BB-39) in that order. The next row to the left has Idaho (BB-42), then New Mexico (BB-40), followed by three of the Tennessee/Colorado class (hard to pick out distinguishing features in this photo), with Nevada (BB-36) as tail-end-Charlie. Further to the left are another Tennessee/Colorado class BB and a Memphis (formerly Tennessee) class armored cruiser. Two unidentified Omaha class cruisers are in the foreground. There are at least 17 destroyers, and two submarine tenders in the foreground with about 10 smaller and two large submarines. (Thanks to Richard Jensen for the identifications.)

Also identifiable (bottom, right) is USS Mahan, by then converted to a minelayer and redesignated DM-7, but still wearing her old DD hull number (102).

The peninsula in the right foreground is South Toro Cay, where the drydock is still visible that was begun in 1904, but cancelled two years later.

With USS West Virginia (BB-48) and the Brooklyn Bridge in the background, the loaded, narrow flight deck of the airplane carrier USS Langley (CV‑1) is moored at the Brooklyn Navy Yard in May 1927. Langley had suffered a generator explosion and was in the process of being repaired after having been towed to the Navy Yard. The planes are Boeing FB-5's and Curtiss TS-1's.

"The Langley was warped by six tugs to her berth at League Island just before sundown after an uneventful voyage from the Canal Zone. The ship has brought back a detachment of 134 Marines released from service in Nicaragua. Six sea planes were on her broad upper deck when she entered port."

USS Langley (CV-1) is seen at anchor at an unknown date/location. Ship's boats are at her port side and some of her boilers are lit. Langley was converted from the collier USS Jupiter (AC-3) to an aircraft carrier at the Norfolk Naval Shipyard.
