Breda-SAFAT (Società Italiana Ernesto Breda per Costruzioni Meccaniche / Breda Meccanica Bresciana - Società Anonima Fabbrica Armi Torino) was an Italian weapons manufacturer of the 1930s and 1940s that designed and produced a range of machine-guns and cannon primarily for use in aircraft.

Based on the M1919 Browning machine gun, the Italian guns were chambered to fire indigenous ammunition with 7.7 mm (0.303 in) and 12.7 mm (0.500 in) calibres, predominantly ball, tracer for the 7.7mm, including high explosive incendiary tracer (HEI-T) (filled with 0.8 grams of PETN), or armour-piercing (AP) for the 12.7mm.

FIAT contested the decision but lost, resulting in the sale of SAFAT to Breda to form Breda-SAFAT.

[2] Thus, Italy lacked machine-guns with the critical qualities of light weight, a high rate of fire, good muzzle velocity, good projectile weight and reliability, while the Soviets, Germans, Americans and Japanese had 12.7 mm calibre automatic ordnance in the Berezin UB, MG 131, Browning M2, and Ho-103 respectively.

Late-war Italian aircraft began to adopt the "original" calibre German Mauser 20 mm (0.787 in) MG 151 cannon to give their aircraft parity in firepower with Allied fighters, with as many as three MG 151 fitted to Macchi MC.205, Fiat G.55 and Reggiane Re.2005—the third cannon firing through the propeller hub of the licence-built Daimler-Benz DB 605 engines (Fiat Tifone) inline inverted V12 engines used to power these aircraft—in addition to synchronized cowl-mounted 12.7mm Bredas-SAFATs.
