The guns on the railway transporter. French 305-mm cannons M 1893 / 96, M 1906 and M 1906 / 10
When using ballistic-tipped shells, the firing range reached 30,9 km. Since the loads arising from the order of fire were much greater than those of 274-millimeter cannons, the main conveyor beam was strengthened, and the five-axle railway carts were replaced with six-axle ones. The rest of the construction of the conveyor remained unchanged.
The tests carried out confirmed the suitability of the conveyor thus upgraded for the installation of high-powered guns. This enabled Schneider to design artillery rail installations with 305-mm naval guns M 1906 and M 1906 / 10, with a barrel length 46,5 caliber. The 1906 M gun was developed at the beginning of the 20th century for the last French battleship of the Danton class, and the 1906 M / 10 M gun for the lean Bart dreadnought. For firing, the same projectiles were used as for the 1893 / 96 M gun, however, the initial speed was 859 m / s, the firing range was 30,8 km. When using 315-kilogram high-explosive projectile having a ballistic tip, the firing range increased to 34 km. This made it possible to hit important targets even in the deep rear of the enemy.
It is noteworthy that the 1906 М and 1906 / 10 М were developed for installation in the newest machines having rollback along the axis of the bore, but they had to be used on rather primitive carriages-conveyors, in which the recoil energy was extinguished after the recoil of the entire artillery installation. It should also be noted that a large mass of guns (about 54 tons) led to a significant increase in the mass of artillery rail installations (up to 208 tons), and the increased dimensions of the gun caused the maximum elevation angle to be limited to + 35 degrees.
Performance characteristics of guns M 1893 / 96 and M 1906:
Caliber - 305 mm
Barrel length - 41,9 gauges / 46,5 gauges;
The largest angle of elevation is 39,5 degrees / 38,0 degrees;
Angle of horizontal fire - 0 hail .;
Weight in the fighting position - 208000 kg;
The mass of the high-explosive projectile - 348,0 kg;
The initial velocity of the projectile - 795 m / s / 859 m / s;
The greatest range of shooting - 27500 m / 30800 m.
