The Dewoitine D.1 was a French single-seat fighter aircraft of the 1920s, built by the French industrial company Dewoitine.

Béarn was an aircraft carrier converted from an incomplete Normandie-class battleship for the Marine nationale during the 1920s. Entering service in 1928, the navy intended to use her to develop tactics and techniques for carrier aviation. The only aircraft carrier France produced until after World War II, the ship played a minor role in early stages of the war, training in home waters and conducting pilot training.
