The Canon de 130 mm Modèle 1924 was a medium-caliber naval gun used as the primary armament on a number of French destroyers during World War II.

The Canon de 130 mm Modèle 1924 had an autofretted built-up barrel and a Welin breech block. Useful life expectancy was 900 effective full charges (EFC) per barrel. These guns were carried in low-angle single turrets on destroyers. They had an automatic spring rammer, but loading was difficult at elevations over 15°.^[1]

Ammunition was of a separate loading QF type. It was the same as that used by the earlier Canon de 130 mm Modèle 1919. The cartridge case was 674 millimetres (26.5 in) long, and together with the 7.73 kilograms (17.0 lb) propellant charge weighed 17.5 kilograms (39 lb).

The gun was able to fire:

• Semi Armour-Piercing - 32 kg (71 lb)
• High Explosive - 34.85 kg (76.8 lb)
• Illumination - Unknown^[2]
