The Scotti 20/70 (Cannone-Mitragliera Scotti da 20/70) was a series of 20 mm (0.79 in) autocannons used by Italy during World War II, firing the 20x138mmB cartridge. While it was primarily used on the defense of airfields and other strategic positions, it was also mounted on ships and some submarines to make up for the shortage of its competitor, the Breda 20/65 mod.35.
