The Type 94 37 mm quick-firing gun (九四式三十七粍速射砲, Kyūyon-shiki sanjyūnana-miri sokushahō) was an

imperial year calendar, or 1934 in the Gregorian calendar.[4]

History and development

The Type 94 37-mm AT gun was introduced in 1936. The design originated as an improvement to the

imperial year 2594 = western year 1934) designation. Approximately 3,400 units were produced.[6] It later was developed into the Type 1 37 mm anti-tank gun
.

Design

A Type 94 gun in the Military Historical Museum of Artillery, Engineers and Signal Corps in Saint Petersburg, Russia.

As with many Japanese designs, it had a very low profile and was intended to be operated from a

breech had a semi-automatic cartridge case ejection system to improve reloading time. When the shell was loaded, the rear of the cartridge case tripped a catch closing the breechblock. The recoil action of firing opened the breech and extracted the cartridge case.[7]

The carriage was equipped with either wooden spoked or perforated steel wheels, and the whole assembly could be broken down into four pack loads each weighing less than 100 kilograms to permit transport in four horse loads. Sighting was by a straight telescopic sight. The gun could fire either

Combat record

National World War II Museum

The Type 94 37mm AT 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. With the standard AP shell, it could penetrate 1.7 inches (43 mm) of armor at 500 yards (460 meters).[8] The Army Technical Bureau continued to experiment with ways to increase muzzle velocity through 1941.[9]

The Type 94 37mm AT gun was effective against

Type 1 47 mm Anti-Tank Gun
was put into service starting in early 1942, and was intended to replace it, but was never available in large enough numbers to do so completely.
