[edit] History

This gun, known as the "three-incher", (трёхдюймовка) was developed by Putilovski Works in Saint-Petersburg at 1902. The lead designers were L. A. Bishlyak, K. M. Sokolovskiy and K. I. Lipnitskiy. It incorporates many new features for that time - carriage with recoil devices, traverse and elevation tracking mechanisms, precision sight for direct and indirect firing, manual interrupted screw breech and single-piece ammunition loading.

For simplifying the mass production process designers used in gun construction cheap types of carbonized steel without or with minimal using rare and expensive nickel-, manganese- or chromium-added types of steel.

The gun has fragmentary, shrapnel and cannister ammunition. More specialized types of projectiles included smoke, incendiary and chemical ones. Many ammunition pieces were French originated.

[edit] Employment

M1902 divisional guns were the mainstay of Russian Empire artillery and were accepted well by the army. Their characteristics were at the same level with similar 75-mm French and German guns. These guns were used in the battles of Russo-Japanese War and World War I. After the collapse of the Russian Empire in 1917 M1902 guns were employed by different factions: bolshevist Red Army, monarchist or counter-revolution White Guard, nationalist forces in Russian-minority areas, national armies of Poland and Finland and simply anarchists and bandits through all vast territories of former imperial Russia.

In some episodes the gun saw its first anti-tank usage. White Guard and intervening forces of Entente Cordiale used small number of tanks, primarily French Renault FT-17s and British Mk Vs and Whippets. M1902 gun with high muzzle velocity was quite effective weapon against targets with only anti-bullet armour protection. In 1920 Polish-Soviet War M1902 guns were again used against Polish FT-17s.

[edit] Interwar development

Poland and Soviet Union modernized their M1902 guns after the end of World War I. Polish designers made their enhancements in 1926, resulting the wz. 02/26 gun, which was rechambered for firing 75mm shells. USSR continued mass production of M1902 gun until 1931 when it was replaced by its enhanced M1902/30 variant. For Soviet modernization see 76.2-mm divisional gun M1902/30. Both variants were utilized at the early stages of World War II.
