Armaments
Main armament
This gun shouldn't be confused with the one on the Chi-Ha Short Gun, while said Chi-Ha has a short gun meant for transport ships on anti submarine & close range fire range, the 12cm/45 10th Year was used as coastal emplacements and outfitted on early Japanese cruisers. It offers a high velocity gun to fling HE over the map with quite an ease.

Usage in battles
Describe the tactics of playing in the vehicle, the features of using vehicles in the team and advice on tactics. Refrain from creating a "guide" - do not impose a single point of view but instead give the reader food for thought. Describe the most dangerous enemies and give recommendations on fighting them. If necessary, note the specifics of the game in different modes (AB, RB, SB).
Pros and cons
Pros:
- High shell velocity
- Quick reload for a gun of its size
- The C.P.(BF) combines the penetration of APHE and the splash-damage capability of HE. The explosion of a non-penetrating hit to a cupola can wreck the roof armor of a tank
- Versatile Chi-Ha chassis
- Quite fast (up to 44 km/h | 39 km/h), allowing it to get to certain spots in time
- Great turning ability in low gear
- Lovely climbing ability, Good to get in sniper locations
Cons:
- Gun shield is small and thin, doesn't provide too much cover
- Only one crew member is inside the tank
- Vehicle can be destroyed due low caliber MG fire even with full crew
- Two loader crew in the back of the tank have no direct cover
- 10 shells max
- Ammunition is very exposed, one lucky shot can destroy the vehicle
- Shells might have some trouble penetrating the front armor of some tanks, especially in uptiers
History
As the Chi-Ha was very structurally sound and is able to withstand high amounts of additional weights while maintaining stable stress-levels and speed. This made it a great testbed for heavier weapons and equipment.
- Design
One of these additions/variants was a Japanese Navy Construction Headquarters refit of the Chi-Ha to carry the 12 cm/45 10th Year naval cannon at the end of the war. Information of the development of the Chi-Ha Long Gun is scarce but what is certain is that they were to be constructed in defence of the homeland in-case of the highly probable American invasion, target allied armour and reposition after being shown.
Very slight changes took place with the most notable being the addition of a muzzle brake. The Chi-Ha would be simply used as a moving platform and hence all the default equipment from turret, hull machine gun, radio equipment and other interior pieces were stripped in exchange for ammo storage. The 12cm cannon was bolted on the hull and used similarly to the Archer in practice, firing from the rear to maintain recoil levels while firing.
The crew consisted out of 5 people; the driver, tank commander, two gun crew, and an ammunition carrier. The cannon could elevate 20° and decline to -10°. Operating the cannon wasn't an easy task either due to the set-up of the gun on the plain back of the Chi-Ha. On top of the fire rate of 2 shells per minute, this would take a massive toll once in actual combat.
- Usage
The first test took place in April of 1945 on mobility and firing. 30 shots were fired at varying distances with upgraded cannon sights, with the longest shot during the test being around 3 km. No discrete information about penetration capabilities were recorded or made it to the post-war reports.
While production plans were approved, no further vehicles beyond the prototype were recorded as being built or near completion by the end of the war.
The prototype recorded by the US was found with the Yokosuka 15th unit and is the only footage on said vehicle.
Devblog
This curious prototype of a self-propelled gun was discovered in the territory of the Yokosuka naval base after Imperial Japan surrendered in WWII. The 120mm naval gun was installed on a turntable mounted to the chassis of a Type 97 Chi-Ha medium tank. It was obvious, that the self-propelled gun was assembled in a rush - the high losses of Japan in the final stages of WWII and a shortage of military production forced the army and naval commands to look for any way to protect the island metropolia of the Empire from the threat of an Allied landing.
The self-propelled gun did not have any protection, the large calibre of the cannon and the weak platform of the medium tank presupposed firing mainly direct fire and in the rather limited arcs of forward and backward to avoid overturning due to the heavy recoil. Despite all these shortcomings, such vehicles were supposed to go into series for rapid deployment in dangerous sectors of the coastal defense line for the Japanese islands and firing at a line-of-sight distance at approaching enemy forces.
