152-mm gun howitzer D-20 in the history of Soviet artillery

The D-20 artillery system was created by Soviet gunsmiths in 1955 and received an index of the Main Artillery Directorate 52-P-546. The gun was created in the postwar years in the OKB-9 under the leadership of F.F. Petrova. The new artillery system was supposed to replace the similar ML-20 weapons of the 1937 type that participated in the Second World War.

Main design features

The created tool was intended to destroy well-fortified objects and disguised targets at a distance of over 17 km. Possessing a high tilt angle of 58⁰, the D-20 cannon could conduct mounted howitzers with high-explosive, concrete-breaking and high-explosive fragmentation shells at hidden targets. A long barrel, a powerful carriage and a developed wheelbase made it possible to use a gun of this type in the front line as a weapon of direct support for the troops.

The gun is made according to the classical scheme: towed carriage with sliding beds, manual semi-automatic loading system. The 34-gauge long barrel significantly increased the ballistic characteristics of the system, making it a universal weapon of warfare. In the Soviet Union, the gun was produced from 1954. In parallel with this, the Soviet new howitzer D-20 was produced in various versions in China and Romania.

One of the most powerful artillery systems of the 20th century is the Soviet D-20 howitzer gun, model 1955.
