The gun was successfully employed in the late stages of World War II,and remained in service into the 1950s, being replaced in Soviet service by the T-12 antitank gun and the 85 mm antitank gun D-48 in 1955. The BS-3 was also sold to a number of other countries and in some of these countries the gun is still in service. A number of BS-3 pieces are still stored in Russian Army arsenals.

[edit] History

The BS-3 was based on a B-34 naval gun. The development team was led by V. G. Grabin.

The gun was employed by light artillery brigades of tank armies (20 pieces along with 48 ZiS-3) and by corps artillery.

In the Second World War the BS-3 was successfully used as a powerful anti-tank gun. It was capable of defeating any contemporary tank at long range. The gun was also used as a field gun. Less powerful than the 122 mm A-19,the BS-3 was more mobile and had a higher rate of fire.
