The SAB AB-20 was a large four engine twin boom French bomber built in the early 1930s as a development of the Dyle et Bacalan DB-70 airliner. It featured a lifting body of thick airfoil section between the inner engines. It was later modified for the attack role; a second aircraft, the AB-21, had different engines and cleaner aerodynamics but no more were built.
