The Blanchard Brd.1 was a French reconnaissance flying boat, to the 1923 STAé HB.3 specification, used by the French navy in the 1920s. It was a large biplane with two engines mounted in the gap between the wings, each engine driving a pusher propeller. In 1924, one Brd.1 was used to set several world altitude records for seaplanes.
