Type 67 Model 30 Rocket Artillery ( 67式30型ロケット弾発射機)
The Type 67 The Model 30 was a Japanese rocket artillery rocket that was intended to destroy enemy landings on Japanese territory. 48 rocket launchers of this type were built, which were used until 1992.
History
In 1955, a year after the formation of the Japanese Self-Defense Forces, discussions began on how to defend the country against the amphibious landing of hostile forces on the home islands. It was decided that long-range artillery, preferably rocket artillery, was needed for defence. It was decided to produce their own long-range missile and not to export such weapons from America or Europe. In August of the same year, research on long-range missiles began.In May 1956, research began on small liquid-propellant rockets. In addition, the Equipment Planning Committee began work on long-range missiles in 1956. In 1959 a mock-up of the rocket was ready, and then the first prototype was ready in 1960. In 1962 the rocket was ready, along with the launcher on which it was to be mounted (only the launcher without the vehicle), the tests were planned for 1965.Unfortunately, due to problems at the proving ground, the tests were postponed to 1968. In June 1968, after tests, the launchers and the loading system were unified. It was decided that it would be a mobile system mounted on a Hino Motors ZC-series truck. On October 3, 1968, the system was introduced to the JGSDF under the name Type 67 Model 30.This launcher was used by the 1st Special Division (第1特科団) ,125th and 126th Missile Battalions from 1968 to 1992.
Structure description
68 Type 30 rocket grenade on the cargo bed of a Hino Motors ZC-series truck. It is equipped with a double launcher. The launcher has a launch rail protruding above the driver’s seat with the cargo box as a fulcrum, and the end of the rail protruding from the rear of the vehicle body. The angle of elevation of the starting rail can be adjusted, but it does not have a horizontal rotation mechanism. Therefore, the rocket is only projected forward and upwards.

Specifications
Type 67 Type 30 Rocket Launcher

Length: 8.24 m
Wingspan: 2.44 m
Height: 3.35 m
Gross Weight: 12t
Engine: Hino Motors DS30 6-cylinder liquid-cooled inline diesel engine (power: 160 hp)
Top speed: 70km/h
Crew: 4 people
Production: Hino Motors (body), Japan Steel Works (launcher)

Type 68 Type 30 Missile

Length: 4.5 m
Diameter: 337mm

Summary
The Type 67 Model 30 rocket launcher would be a very interesting vehicle for the Japanese tech tree. It is a combination of mobility (70 km/h) and powerful firepower (227 kg warhead), but at the price of weak armor (none). You could say it’s a Katsusha with Sturmtiger missiles, which is a very interesting vehicle for Japan. This would be a very nice premium addition for Japan. I encourage you to discuss in the comments and share your own knowledge on this topic.
Finally, I apologize for the linguistic and logical errors because unfortunately English is not my main language and I had to use google translator.

+1 because funny but I’m pretty sure it’d be nearly useless due to the fact that it can’t aim anywhere near 0 degrees.

Neither can the Russian equivalents in game, so they got a feature where the vehicle can lower the front and “dig in”

Doesn’t seem practical, but would be an interesting event reward.

Says the truck had 6 cylinder inline diesel engine with 160hp output.

I have retrieved some extra data from official specifications of the vehicle and related equipment.

Launcher
There are two variants: the original Type 67 and the Type 67 (B). The B variant was introduced one year after the original. As far as I know, the only difference is the minimum elevation angle.

Horizontal guidance: -16°/+16° [1,2]
Vertical Guidance: 12.5° – 55° for the original Type 67 [1], 6.5° – 55° for the B variant [2]
Slope Compensation: over 5° [1,2]
It has a set of hydraulic jacks, that enable it to compensate for slope.

Optics
Some of the items listed below were not mounted on board.

Type 61 quadrant JM1 [1,2]
- Limit: 0 mil – 1600 mil [9]
- Main scale interval: 10 mil [9]
- Vernier range: 0 – 10 mil [9]
- Vernier interval: 0.2 mil [9]
JM12A7C panoramic telescope [1,2]
Likely licensed M12A7C panoramic telescope, based on the naming convention.
JM25 panoramic telescope mount [1,2]
Likely licensed M25 panoramic telescope mount.
JM1A2 Aiming post [1,2]
Likely licensed M1A2 aiming post.

Mobility
The launcher uses Type 56 4-ton 6x6 Cargo Truck chassis. The truck also had two variants, but it is likely that the B variant was used for the rocket launcher, since the Type 56 (B) was introduced in 1957.

Maximum speed: over 70 km/h [1,2]; over 65 km/h [3,4]. (likely dependent on cargo weight)
Maximum slope: over 35%[1,2]; over 40% with speeds above 3 km/h [3,4].
Minimum turning radius: less than 11.5 m [3, 4].
Maximum output: over 141.0 HP [3]; over 1410 ps [4]. (probably a typo for 141.0)
Minimum RPM without load: under 400 rpm [3].
Maximum RPM: 2550–2600 rpm [3], 2500 – 2600 rpm [4]

Main transmission gear ratio:

gear	ratio
1st	5.107 [4]
2nd	3.083 [4]
3rd	1.722 [4]
4th	1 [4]
Reverse	6.489 [4]

Transfer gearbox:

gear	ratio
high	0.862 [4]
low	1.403 [4]

Final drive:

ratio
7.559 [4]

Rocket
The rocket uses a spin motor for stabilization, ignited 2.5 seconds before launch [5]. Combined with the relatively long and sturdy launch rail, this system should provide relatively good accuracy for this type of vehicle.

Spin motor propellant: 2.6±0.1 kg [5]
Main motor propellant: 190.0±0.5 kg [5]

Loader Vehicle

Capacity: 6 rounds [7,8]
Maximum speed: 70 km/h [7,8]

Discussion
There are the original Type 67 and B variant. The B variant has a lower minimum elevation, which should reduce the minimum firing distance. I believe the B variant would be more suitable for implementation, as the original’s minimum range may be too long given its long maximum range and presumably high initial velocity.

The launcher is equipped with three hydraulic jacks that can tilt the vehicle to compensate for slope. This effectively reduces the minimum elevation to about 1.5°, which would make a significant difference. However, I am not sure how this should be implemented in the game. A controlling system similar to hydraulic suspension would work, but the jacks should not be operable while the vehicle is moving.

Regarding ammunition: currently the game only gives 4 rounds including the ammo box, which feels too low. Since the real launcher was designed to be accompanied by a 6-round-capacity loader vehicle, the ammo box should be larger to reflect this. I suggest 2 × (2 + 6) = 16 rounds (2 on the launcher, 14 in the ammo box).

The transfer gearbox effectively doubles the number of the gears.

Summary
I have gathered additional information from official specifications. I hope this helps Gaijin with the implementation of this vehicle.

+1 Hopefully we get TT artillery for all trees

Thanks for the great information

shoot at the building infront. probaly just like the RBT-5 or use the Katyusha strategy by sending the rocket to capture point shooting from spawn and you will guarantee atleast 1 kill.
