Atelier de Construction de Puteaux

The Atelier de Construction de Puteaux (APX) (English translation: "Puteaux Construction Workshops") was a state arsenal belonging to the French Army. It was located at 8, quai national in Puteaux.

History

Atelier de Construction de Puteaux was in charge of making ammunition and carrying out tests. The factories also produced small and medium-sized equipment (firearms and knives), while the so-called “manufacturing” workshops produced larger equipment (artillery pieces).

Atelier de Construction de Puteaux disappeared after the Second World War, being transferred to Satory and merged with Ateliers de construction d'Issy-les-Moulineaux (AMX), which specialized in the construction of tanks and other armored vehicles.

Atelier de Construction de Puteaux had two responsibilities:

To design new weapons for the French Army. It specialized in small arms and medium caliber weapons and their accessories: such as machine guns, cannon, tank turrets, Telescopic sights for rifles, missiles etc.

And for serial production of those weapons, alone or concurrently with other factories.
