138.6mm / 50 Model 1934 - 138 mm naval artillery gun designed and manufactured in France . Was in service with the French Navy . It became the development of a 138.6 mm / 50 Model 1929 naval gun. Intended for the arming of the counterminers of the new generation. These tools were equipped with counter-bearers of the Mogador type . It was also supposed to equip counter-bearers of the Kleber type with these guns, but they were not laid in connection with the outbreak of the Second World War .

Construction
According to its design, Model 1934 cannon basically repeated Model 1929 . They had the same barrel, a monoblock with a length of 50 calibers and a semi-automatic wedge gate . The differences between the weapons consisted only in the loading mechanisms and the type of the gun installation [2] . Model 1929 had a manual loading, and the Model 1934 combined, in which the projectile was charged mechanically, and the sleeve was sent manually. In fact, the loading system on the Mogador type turned out to be technically underdeveloped and unreliable. It was supposed to achieve a rate of fire of 14 rounds per minute per barrel, but then it was first lowered to 12 rounds per minute and then to 10, which corresponded to the Model 1929 rate of fire. In practice, the long-term rate of fire initially did not exceed 3–5 shots per minute, and only after strenuous training of the calculations and fine-tuning the mechanisms was it possible to achieve a long-term rate of 8 shots per minute, and for a short time — 10 shots per minute [3] .
Ammunition
The guns fired shells of two types - armor - piercing , weighing 40.6 kg and high-explosive , weighing 40.2 kg. The weight of the propellant charge was 12 kg, as in the previous model. The armor-piercing projectile contained 2.3 kg of explosive . The armor penetration reached 151 mm of armor at a distance of 27 cables (5000 m), 81 mm at a distance of 54 cables (10,000 m) and 57 mm at a distance of 80 cables (14,816 m). Thus, 138.6 mm projectiles were dangerous even for cruisers [4] .
