The M1919 Browning is a .30 caliber medium machine gun that was widely used during the 20th century. It was used as a light infantry, coaxial, mounted, aircraft, and anti-aircraft machine gun by the U.S. and many other countries, especially during World War II, the Korean War, and the Vietnam War...

Development

The birth of these weapons came from the desire to have better machine-guns to face a new generation of enemy aircraft, with their higher performance and better armor. Breda based their designs on Browning machine-guns, adapted for Italian exigences, in particular with the change of cartridges from 7.62×63mm to 7.7×56R and from 12.7×99 to 12.7×81mm. The latter especially weakened the weapon and the goal of a lighter machine-gun with a high rate of fire was a failure. In any case, the completed gun saw competition from similar projects produced by the powerful industrial group Fiat, which proposed new weapons designed by its subsidiary factory, SAFAT (Società Anonima-Fabbricazione Armi Torino). But Breda/Browning weapons proved superior, the heaviest Browning machine-gun was five kilograms lighter than the Fiat-SAFAT. Despite attempts by Fiat to sell their design, the Regia Aeronautica

 (Air Force) selected Breda for the contract. Fiat still did not surrender and launched a lawsuit aimed at Breda. But Fiat lost their case and the court ordered it to pay the trial expenses as well. After this failure, Senator Giovanni Agnelli was so irritated that he decided to exit the small arms industry for the next twenty years, selling SAFAT to Breda itself. Fiat's predominance in machine-guns ended, the rise of Breda began. (It was then an almost minuscule factory in Brescia.)

Comparison

The muzzle velocity of the Breda 12.7 mm was less than other .50 caliber machine-guns because its ammunition was 12.7×81 mm and not 12.7×99 mm or 12.7×108 mm. The Breda's muzzle energy was only 10,000 joules compared to the 16,000–17,000 joules of other cartridges. The Breda guns were reliable, but they had the worst power-weight ratio of all machine-guns mounted on World War II aircraft. In comparison, the Japanese Ho-103 had a similar 12.7×81mm round, but the gun was 6–7 kg lighter and had a rate of fire of 800–900 rounds per minute with a 34.2 gram projectile. The Japanese gun's rate of fire was at least 20% better, but it was still reliable. Isotta-Fraschini

 Scotti tried to improve the Breda's performance, but it could still not match the Japanese weapon's better rate of fire or reliability. Despite the availability of high-explosive ammunition, Italian pilots preferred the armor-piercing and incendiary rounds to the weak destructive capability of a mere 0.8 grams of explosive. It is untrue that other countries did not adopt high explosive 12.7–13.2 mm caliber rounds. Almost all did so, but they rated this ammunition too weak to justify its cost, it also did little damage to metal structures. On top of this, they were not effective against armor. High-explosive rounds were only common with guns in a caliber of 20 mm or larger. British experts called the high explosive smaller caliber rounds "ridiculous". The US only tested a few examples of HE 12.7 mm ammunition.

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 Russians, Germans, Americans and Japanese had them in the Berezin

 in 1935. Nevertheless, thousands of Breda guns were built in the 1930s and 1940s, arming nearly every Italian fighter and bomber of that period. Many of these weapons were also adapted for the anti-aircraft role and remained in service until the 1970s as reserve weapons; even if all the aircraft that they equipped had been phased out by that time. The last heavy machine-gun used on Italian aircraft was the Browning M3, as used on the Fiat G.91R.
