Description

The barrel, with a weight of 83.3 t (82.0 long tons; 91.8 short tons), came from the battle-cruisers of the Borodino-class, which were never completed.

The armour piercing shells, with a weight of 747 kg (1,647 lb), flew up to 31 km (19 mi), with a speed of 731 m/s (2,398 ft/s). Later versions, with a weight of 512.5 kg (1,130 lb), flew up to 44.4 km (27.6 mi), with a speed of 950 m/s (3,117 ft/s). High explosive shells, with a weight of 473 kg (1,043 lb) reached up to 65 km (40 mi). ^[1] 3 charges were used.

In transport-configuration the height was 5.35 m (18 ft). Transition to firing-configuration took one to three hours, where lifting up the gun took 23 minutes.

A rate of fire of 45 rounds per day could be attained ^[1]

The gun also could be installed on a firing platform.

Three guns each were in service with the 6th Railwaybattery of the Pacific Fleet and the 11th Battery of the Baltic Fleet.
