Model 94 Japanese 37mm Anti-Tank Gun


This Japanese Model 94 37mm Anti-Tank Gun is displayed at the "Purple Heart Park" on Hwy. 32 in Fertile, Minn. This was an anti-tank gun developed by the Imperial Japanese Army and used in combat during World War II. The Type 94 number was designated for the year the gun was accepted, 2594 in the Japanese imperial year calendar, or 1934 in the Gregorian calendar. The Model 94, 37mm Anti-Tank guns were typically assigned in groups of four to combat infantry regiments. Each weapon was manned by a squad of 11 personnel, and was kept in contact with the regimental headquarters (typically up to 300 meters) away by field telephone or messenger runners. The Army claimed a penetration capability of 20 mm of armor at a distance of 1000 meters, and penetration of up to 40 mm at shorter distances. However, it appears unlikely that this performance was achieved in actual combat, as the Army Technical Bureau continued to experiment with ways to increase muzzle velocity through 1941. The Model 94, 37mm Anti-Tank gun was effective against the Soviet's light armor in the Nomonhan Incident of 1939, but was considered obsolete against more advanced Allied tanks, such as the M4 Sherman by the start of the Pacific War. However, it remained in service on most fronts in World War II for lack of a better replacement.
