The Lioré et Olivier LeO 12 was a night bomber built in France in 1924. It was a large biplane of conventional design with three-bay equal-span wings and twin engines mounted in nacelles on struts in the interplane gap. The independent main undercarriage units were faired in long trouser-style spats. Construction throughout was mainly duralumin skinned in fabric. The pilot's cockpit was open and there was a second cockpit amidships for a gunner.
