The Aeromarine 39 was an American two-seat training seaplane ordered by the US
Navy in 1917 and built by the Aeromarine Plane and Motor Company of Keyport, New
Jersey. Of conventional biplane configuration and construction, the aircraft was
designed so that its pontoons could be speedily detached and replaced with
wheeled undercarriage for shore operations.

Fifty of the original design (later referred to as the 39A) were produced,
featuring twin floats and powered by a Hall-Scott A-7 engine. A redesign
followed, increasing the wingspan to create more lift for water take-offs. This
became known as the 39B. Other changes included a change to a single pontoon
with outrigger floats, an enlarged vertical tail, and a change of powerplant to
the Curtiss OXX.

On October 26, 1922 Godfrey DeCourcelles Chevalier landed a 39B on a moving
ship, USS Langley, the first time this had been achieved on an American aircraft
carrier. Trials of underway carrier takeoffs and landings continued through 1922
and 1923.
