Intended to equip the French Navy, only a single prototype was completed before the German invasion of France stopped production.

The Potez-CAMS 141 was designed by Chantiers Aéro-Maritimes de la Seine (or CAMS, which since 1933 had been part of Potez) to meet a 1935 French Navy specification for a long range marine reconnaissance flying boat to replace obsolete aircraft such as the Breguet Bizerte, competing against the Latécoère 611 and Breguet 730.

[2] Additional large orders for Potez-CAMS 141s were placed shortly after the start of the war, with delivery expected from June 1940, but these orders were cut back owing to changing priorities and the realisation that the loss rate of long range flying boats was very low.

[1] No production aircraft had been completed by the time of the Armistice in June 1940, with Antarès being evacuated to Port Lyautey in Morocco.
