Design
The 138.6 mm / 40 Model 1923 gun was proposed for arming the French counter-carriers by the chief of the Technical Department of the Naval General Staff, General Engineer M. Antonet. Believing that the 130-mm Model 1919 guns used on the first series of French Jaguar-type counter-bombers did not provide decisive fire superiority, he put forward the idea of moving to a larger caliber.
Being a very powerful artillery system, it had an absolutely inadequate rate of fire for its tactical purpose due to the use of a piston shutter . In addition, in an attempt to provide significant range without the use of balancing devices, the designers placed the trunnions of the guns at a height of 1.5 meters, which made loading very difficult, despite the presence of a spring reloader. The calculations experienced particular difficulties at low elevation angles, when the breech of the gun was at the level of their shoulders.
