History
History
The Breda Model 31 was a license built copy of the French Hotchkiss M1929 machine gun. Breda acquired a production license in 1929, but it did not enter production until 1931. The Model 31 was often mounted on single and twin mounts aboard surface ships and on a disappearing twin mount aboard submarines. The Model 31 was intended to provide close-range air defense, but like its counterparts in other nations, these small-caliber guns were found incapable of defending against low-level torpedo-bombers or high altitude level-bomber attacks because their bullets were too light and short ranged. Although a reliable gun with good performance, it was later replaced by the Breda 20/65 Mod. 1935.
