3-inch M1902 field gun
The M1902, ''a.k.a. M1905'' 3-inch gun (76.2mm) was the U.S. Army’s first steel, rifled, breech loading, quick-firing field gun.
==Design==
The features of rifling, breech loading and springs to absorb the gun's recoil and quickly return it to the firing position combined to improve the range, accuracy, and rate of fire of the gun, allowing it to be used more effectively in operations with infantry. These new capabilities allowed the gun to provide accurate indirect fire on targets not in a direct line of sight, which provided crucial firepower for infantry attacks. It was also one of the first artillery guns to have an armored shield to protect the crew from small arms fire. The gun fired Shrapnel or Explosive Shells that weighed 15 pounds (6.8 kilograms).〔(M1902 3 Inch Field Gun )〕 This was of a heavier poundage than the older guns, in its role, could cope with (the use of steel provided this benefit) meaning that the M1902 could fire a shell (when taking note of the use of tighter rifling) at a greater muzzle velocity at a greater accuracy than any other field gun of American origin to that point. It had a muzzle velocity of with an effective range of , and a maximum range of . The maximum rate of fire was 15 rounds per minute.
This was not the same weapon as the 3-inch M1902 seacoast gun, which was designed by Bethlehem Steel and was mounted in fixed defenses.
