Pros and cons

Pros:

• Good muzzle velocity
• Acceptable rate of fire
• Good vertical guidance

Cons:

• Below-average damage output
• No gun shield

History

The 75/50 Modèle 1922 was a french gun designed during the dawn of the interwar period specifically to provide light French warships with the medium-range anti-air capability.

It was able to elevate -10° down or up to 90° up, being able to engage targets directly above the ship. It had a theoretical rate of fire of up to 15 rounds per minute (one each 4 seconds), but during trials it achieved an average rate of fire of 8 rounds per minute. Guns weighted a total of 1.07 tone.

The Gun used two types of shells:

• OEA Modèle 1925 - time-fused anti-air shell able to engage enemy airplanes up to 7500 meters altitude when firing 90° up. Shell had a total mass of 12.01 kg with 5.93 kg explosive filler, fired with a single BM5 propellant bag (2.18 kg)
• OEcl Modèle 1923 - Illumination rounds
• Practice - these were used for sea trials, salutes and warning shots
