The original 75 mm SA 50 gun was loaded by an automatic loading system fed by two six-round magazines located in on either side of the automatic loader in the turret's bustle.

The turret is set to the rear of the vehicle and holds the commander and gunner. It features an uncommon two-part FL-10 oscillating turret, where the gun is fixed to the turret and the entire upper turret changes elevation. The compact chassis had torsion bar suspension with five road-wheels and two return rollers the engine runs the length of the tank on the right side, with the driver on the left. The tank was designed at the Atelier de Construction d'Issy-les-Moulineaux (AMX) in 1946 to meet a requirement for an air-portable vehicle to support paratroopers.
