Mod «Type 1 47mm Anti-Tank Gun» for Ravenfield (Build 19)

The Type 1 47 mm anti-tank gun (一式機動四十七粍速射砲) was an anti-tank gun developed by the Imperial Japanese Army, and used in combat during World War II.

This cannon was introduced to combat service only in 1941, with the intent of it replacing the Type 94 37 mm (1.5 in) anti-tank gun. It was very effective for its role, with American personnel calling it "an excellent weapon, with mechanized carriage and a high muzzle-velocity" that "proved most effective in combat", though it was not always available in sufficient numbers.

It had a high rate of fire and with AP shells was capable of perforating the front armor of the M4A6 (a slightly more heavily armored variant of the M4 medium tank at 800 yards (730 m), though standard doctrine was to wait until tanks got closer if possible to ensure good shot placement.

A variant known as the Type 1 47 mm tank gun was used as the main armament of the Type 97 Shinhoto Chi-Ha, Type 1 Chi-He, Type 3 Ka-Chi, and Type 5 Ke-Ho tanks.
