The BR. 20 “Cicogna” (“Stork”) was designed by Celestino Rosatelli (BR = Bomber Rosatelli) to a 1934 specification for a twin-engine medium bomber for the RA. Although barely in service with the Regia Aeronautica in 1937, the Fiat BR. 20 was pressed into combat service with Spanish Nationalist forces in the summer of 1937 which is where it saw the majority of its combat service. Deployed to counter the growth of the Republican Air Force, the type also saw action when Mussolini invaded southern France.
