Comparison with analogues
- Pak.(t)(Sf.) (47 mm) - The German (Czech) cannon has the longest barrel 47 mm in-game with far better accuracy but doesn't keep up in initial velocity and is filled with less HE filler.
- 20-K (45 mm) - Less velocity and penetration with more HE filler
- 47/32 mod.39 (47 mm) - Far less velocity and penetration with more HE filler
Usage in battles
Pros and cons
- Relatively high velocity
- Short barrel results in bad accuracy at longer ranges
With the service of the Type 94 (37 mm) in the early 1930s and the overall low amount of armour on the Sino-Japanese front, Japanese anti-tank development didn't get high priority but didn't stop the Army from experimenting to improve on the Type 94.
Improvement started on the shells, giving them more capacity and penetration characteristics. Afterward, development called for a new caliber anti-tank gun increasing it to 47 mm. By 1937 the prototype cannon was dubbed the 47 mm Type 97 Prototype Cannon and had a barrel length of 2515mm, an initial shell velocity of 730m/s, and a weight of 567kg. Multiple examinations took place from March testing the human towing and mobility of the gun carriage, In November the ballistics were tested.
In 1939 after the Nomonhan Incident (Battles of Khalkhin Gol), The Japanese weakness in tank forces was portrayed with the low velocity of the Chi-Ha's 57 mm getting out ranged by lightly armoured Soviet T-26 and BT-series. But the overall anti-tank effectiveness of the Type 94 (37 mm) field gun and Ha-Gos were sufficient enough to finish Soviet armour but still after a Japanese defeat, it provided Army High Command a valid reason to further develop improvements to anti-tank and tanks.
In September of 1939, development to increase anti-tank capability started. The development in 1941 moved to further developing the 47 mm Type 97 Prototype Cannon and a redesign took place. By July a trial production of the 47 mm Type 1 Mobile Trial Cannon began and by May 1942 production and formalized as the 47 mm Type 1 Mobile Cannon.
The changes over the 37 mm Type 94 and 47 mm Type 97 Prototype included a new suspension to the cannon and rubber tires instead of steel / wood making it towable by vehicles mobilizing Japan's cannon arsenal.
Parallel to improving the cannon, a tank gun variant was being developed to improve the Type 97 Chi-Ha, it simply used the same cannon with a slightly shorter barrel resulting in slightly less velocity and penetration with the same shells.
