The Bréguet 14 was a French biplane bomber and reconnaissance aircraft of World War I. It was built in very large numbers and production continued for many years after the end of the war.
Apart from its widespread usage, the Bréguet 14 is known for being among the first mass-produced aircraft to use large amounts of metal, rather than wood, in its structure. This allowed the airframe to be lighter than a wooden airframe of the same strength, in turn making the aircraft relatively fast and agile for its size; in combat it was able to outrun many contemporary fighters. The Bréguet 14's strong construction allowed it to sustain considerable damage, in addition to being easy to handle and possessing favourable performance. The type has often been considered to have been one of the best aircraft of the war.
