The 76.2 mm divisional gun model 1902 (Russian: 76-мм дивизионная пушка образца 1902 года) was a Russian light field gun used in the Russo-Japanese War, World War I, Russian Civil War and a number of interwar armed conflicts with participants from the former Russian Empire (Soviet Union, Poland, Finland, Estonia, etc.). Modernized versions of this gun were employed at the early stage of World War II.
This gun, known as the "three-incher", (трёхдюймовка) was developed by Putilovski Works in Saint-Petersburg in 1902. The lead designers were L. A. Bishlyak, K. M. Sokolovskiy and K. I. Lipnitskiy. It incorporated 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 the gun's construction cheap types of carbonized steel without or with minimal use of rare and expensive nickel-, manganese- or chromium-added types of steel. Early version had two seats for the crew on both sides of a barrel, from 1906 they were replaced with an armoured shield. The shield had a specific design: an outer shield, with a big rectangular opening, and a smaller, inner shield behind it. The upper and lower portion of the bigger shield were folding during transport.
