Summary

The 100 mm D-10 Gun is a Soviet tank gun based off the BS-3 Field Gun of the same caliber. It was issued late in the war in 1944 on the SU-100 tank destroyers, to which it performed very favorably against the German tanks of World War II. After the war, the D-10 gun was tested on a tank mount, fitted onto the T-34 and T-44, but these proved a failure due to the impracticality of the large gun in the small turrets. When the next generation of tank was developed in the form of the T-54, it was equipped with the D-10 gun, to which it continues to use to this day.

History

Development

In the later half of World War II, the Soviet T-34 tank was becoming under gunned by the better German tanks such as the Panther and Tiger tanks. The T-34 was thus upgraded with the 85 mm gun. While this upgrade was implemented, the current tank destroyer SU-85 was put obsolete due to the lack of firepower advantage. Thus, Fyodor F. Petrov's design bureau at Artillery Factory No.9 was assigned to develop a 100 mm gun superior to the 85 mm gun. The design bureau took a S-34 naval gun and modified it for mounting on an armored fighting vehicle. The gun was designated the D-10 gun.

Service

The D-10 was first used on the SU-100 tank destroyer by adapting the SU-85 into holding the D-10 gun. The D-10 in this mounting was called the D-10S (S for samokhodnaya, or "self-propelled"). Late in the war, the 100 mm cannon was tested on a various of different tanks for its use as a tank armament. The T-34 was adapted to hold the 100 mm gun in a various of configuration in an attempt to increase its firepower, but the restrictive turret size and turret ring made this an impractical application of the gun. The next tank tested for the gun was the T-44. The adaption was seen as successful, but the improving tank technology and development at the time meant that the adaption was not mass-produced and will instead be used on the next Soviet tank in service. This led to the next Soviet tank, the T-54, into mounting the D-10, now designated the D-10T (T fortankovaya, or "tank").

In 1955, the D-10 underwent a modernization with upgrades implemented in the design, becoming the D-10TG. A vertical stabilizer was added to the gun and a bore evacuator was also installed to vent out the propellant gases. Another upgrade is the D-10T2S that has a two-plane gun stabilization system that equipped the later tank models produced in 1979. Today, the D-10 gun continue to see use in naval and tank mounts in various countries, staying relevant with evolving fire control systems and other mechanics.
