MAS AAT-52 (Arme Automatique Transformable Modele 1952)

History

The AAT-52 ("Arme Automatique Transformable Modele 1952") was introduced in 1952 as the standardized General Purpose Machine Gun (GPMG) for the French Army and its colonial forces around the world. During the First Indochina War, France's growing combat experience with various foreign-born machine guns inspired design work, resulting in the need for a French-made solution of equivalent form and function to simplify logistics, supply and training.

The design of the new GPMG fell into the long-held attention of the Manufacture d-Armes de Sain-Etienne (MAS), and the AAT-52 series was born, which continues (albeit limited) service in the modern French army. During its long life cycle, it has also been adopted by Belgium, Central African Republic, Cote d'Ivoire, Ireland, Madagascar, Morocco, Niger, Somalia and more.

As originally designed, the AAT-52 was fitted for the French 7.5x54mm rifle cartridge, although Western conversion to a single NATO-sized 7.62x51mm rifle cartridge modified the AAT-52 design, resulting in the AA 7.62mm designation "NF-1". These soon replaced the manufacture of the 7.5mm type.

Although the muzzle velocity of the new cartridge was slightly reduced, the machine gun was now more standardized in shape and conformed to general NATO standards.

Although the AAT-52 is constructed around a lever-delayed recoil action, the design of this weapon remains largely traditional, representing a departure from the world norm of military machine guns. Feeding through a 50-round belt system had some influence on the German MG42 series during World War II. The AAT-52 has a rate of fire of 900 rounds per minute, a muzzle velocity of 830 meters per second, and an effective range of up to 600 meters.

By default, the maximum range is 3,200 meters, aimed via iron sights, enhanced by the use of optional optics for precise long-range shooting. The barrel is air-cooled, placing the onus on the shooter to overheat the barrel to prevent warping and breakage due to high temperatures from prolonged continuous shooting. The total weight of the system is almost 9.75kg and the overall length is 1,080mm (barrel length is 600mm).

A carrying handle is usually installed behind the barrel and helps with barrel changes. The weapon is managed using a traditional pistol grip with a ring trigger unit.

As a GPMG, the AAT-52 was eventually deployed in a variety of forms to meet battlefield needs. As a light machine gun, it is equipped with a collapsible bipod mounted under the barrel, and a light barrel assembly to reduce carry weight. A monopod can also be mounted under the stock behind the pistol grip for extra support when firing from the prone position. A heavy tripod and heavy barrel combination can quickly turn the AAT-52 into a defensive stationary machine gun.

Machine guns can also be used as vehicle weapons, as a coaxial system mounted on tank turrets (including the French LeClerc MBT) and similar armored vehicles, on trunnion brackets on open-top light armored vehicles such as armored vehicles, and on trunnions mounted on attack aircraft (Fouga Magister) and helicopters.

To date, the AAT-52 has been used in many notable conflicts, including the First Indochina War (1946-1954), the Algerian War (1954-1962), the Suez Crisis (1956) and the Gulf War (1991) . ), the Bosnian War (1992-1995), the Afghanistan War (since 2001) and the Libyan Uprising (2011). The modern French army has since replaced its inventory of AAT-52 guns with other solutions, including the Belgian FN MAG GPMG series on gunship transports and the Belgian FN Minimi for squad support.

The weapon has seen modern combat operations in recent operations involving French and local forces in Mali.

MAC-58 is proposed. A 50 BMG chambered machine gun version of the AAT-52 family, which was evaluated but never produced because it had to compete on the world stage with the excellent and historic American Browning M2 heavy machine gun, which has been embedded in dozens of armies in the world.
