Introduction

The AAT-52 is a machine gun of French origin. It was developed in the early 1950’s to replace the various weapons in different calibers in service up to that point. The name AAT-52 stands for Arme Automatique Transformable Modèle 1952, which translates to transformable automatic weapon, model 1952. This refers to its use as a general purpose machine gun, being both carried by infantry, used on tripods and fitted to vehicles.

Design

The AAT-52 has a peculiar design using a lever-delayed blowback mechanism. A telescoping metal buttstock is fitted as well as metal pistol grip with plastic grip plates. The barrel can be easily changed, with a light barrel available for infantry use and a heavy barrel for mounted use. The light barrel is fitted with bipod and carrying handle.

Firepower

The AAT-52 fires the 7.5x54mm French round from interconnectable 50 round belts. The AAT-NF1 is a modified version to cater the 7.62x51mm NATO round using US M13 links. The rate of fire is rather high with a cyclic rate of fire of 900 rpm. The effective range from the bipod is 600 meters. This increases to 1 km when mounted on a tripod or vehicle.

Users

The main user of the AAT-52 was France, using it in the infantry role as well as mounted on various vehicles and aircraft. With the adoption of NATO ammunition the AAT-52 was converted to 7.62x51mm NATO. Large quantities in both calibers have been exported to nations with close ties to France. In French service the AAT-NF1 is being replaced by the Minimi in the infantry role and by the MAG for vehicle use.
