Japanese Artillery.,
Continuing with the Japanese defences, here are their fixed artillery weapons.

Type 91 105mm

During the 1920 the Japanese Army Technical Bureau bought several French Canon de 105 mle 1913 Schneider howitzers for evaluation purposes, impressed with the design a further 300 were ordered from Schneider. In 1931 a locally produced Japanese version was put into production as the Type 91 and became the standard Japanese Army light howitzer with over a 1,000 produced during the war.

Type 96 150mm
Type96_150mm.jpg
During the mid 1920 the Japanese started work on a new 150mm howitzer to replace the Type 4 15cm (model 1915). Development lasted for over a decade and went through several stages, the design was finally accepted in 1936 but some changes were still needed and mass production didn't start until 1937. The Type 96's protracted development proved to be beneficial as the end result was considered to be one of the most modern and effective howitzers of WW2. One the Type 96's main features was the ability to fire at an elevation of 65°, but this was only possible when a pit was dug beneath the breech.

Type 4 40cm

Type4_40cm.jpg
The development of a heavy spin stabilised rocket mortar was started in 1942 to replace the Type 98 32cm Spigot Mortar. The first prototypes used a large steel launch tube but this proved to be overly complex and a simpler triangular frame with wooden rails was designed. Mass production started in late summer 1943 and by early 1944 several Rocket Battalions had been formed and equipped with this new weapon. The Type 4 was used in combat for the first time during the Battle of Luzon where over a 1,000 were fired, it was also used during the fighting on Iwo Jima and Okinawa. Many launchers and rockets were also stockpiled in Japan for the expected invasion.

Japanese Anti-Aircraft Guns.,

Following on from the last news post here are the Japanese Anti-Air defences, which range from one of the smallest to the biggest AA gun ever used.

To see more information and photos of these guns click on the images to go to their Wiki pages.

Type 96 25mm
Type96_25mm.jpg
In 1935 the Japanese were looking for a new light naval anti-aircraft weapon to replace their Vickers 40mm guns. A group of officers & engineers traveled to France to inspect the 25mm Hotchkiss design, several were bought back to Japan & tested at Yokosuka Navy Yard as the Type 94/95. Soon after a license was agreed & mass production started in Japan as the Type 96. It became the standard Japanese light anti-aircraft weapon with nearly 33,000 built by the end of the war.

Type 99 88mm
Type99_88mm.jpg
Following the battle of Nanking in December 1937 the Japanese captured several German 88mm SK c/30 anti-Air guns that had been bought by the Chinese Kuomintang army. After examining them they realized that they were superior to their own anti-Air guns so work stared on reverse engineering the design & in 1939 a copy of it was put into production as the Type 99. Because of their superiority most were kept on the Japanese home islands to defend vital areas against the Allied air raids.

Type 5 150mm
Type5_150mm.jpg
The Type 5 15cm is the largest anti-aircraft gun ever deployed in combat. Developed from the earlier Type 3 12cm which was designed specifically to counter the Boeing B-29 Superfortress, however it was soon found that the B-29 could fly even higher then the Type 3's effective range so an even bigger gun was needed. Development proceeded quickly & a prototype was soon ready but with Japan's infrastructure destroyed & limited resources only two were built before the end of the war. The two guns were deployed to Kugayama in the outskirts of Tokyo, in their first engagement on 1 August 1945 they successfully shot down two B-29s. Seeing the threat from these new weapons the USAF avoided flying near Kugayama for the rest of the war, so even though they were only used once they still defended Tokyo as an effective deterrence.

Japanese Anti-Tank guns,

Today's news post focuses on Japanese Anti-Tank defences, which range from the inadequate, the opportunistic and the mighty.   

To see more information and photos of these guns click on the images to go to their Wiki pages.

Type 1 47mm
Type1_47mm.jpg

Work on Japan's first indigenous anti-tank gun design started in 1937 with several experimental prototypes built, none were put into production though because of inadequate performance. Following the defeat of Japanese forces to the Soviets During the Nomonhan Incident in 1939 interest in a new anti-tank gun resurfaced. Work on the design continued over the next few years and was finally completed in 1941 and standardised as the Type 1 47mm, production started in 1942 and it was deployed into service during 1943. By then the Allies had introduced newer tank designs witch the Type 1 was unable to effectively defeat, however with no other anti-tank guns available it continued to be used until the end of the war.

Available Pre & Early war.

Type 90 75mm
Type90_75mm.jpg

Designed in 1930 the Type 90 75mm was a field gun based on a French Schneider cannon, the design was an effective weapon but expensive and very complex to build and maintain. It was originally designed as a field gun/light artillery but during the later stages of the war the Type 90 was also successfully used as an anti-tank gun, being one of the few weapons that could effectively defeat the newer Allied tanks. In light of this the weapon was modified and used in the Ho-Ni and Chi-Nu tanks.

Available Mid & Late war.

Type 5 105mm
Type5_105mm.jpg

The Type 5 was an experimental anti-tank gun developed in 1945 during the closing stages of WW2, the Japanese had planned to use this weapon in the Type 5 Ho-Ri tank destroyer but the war ended before a prototype of the Ho-Ri was built.

Available Post war.

Japanese Amphibious Tanks,

You thought I was done with Japanese tanks!? Well think again because there are plenty more to come :p Japan was the only country during the war to operationally use mass produced tanks that were specifically designed to be amphibious. These tanks are now buildable in D-day, allowing Japan strike swiftly on both land and sea.

To see more information, diagrams and photos of these units click on the images to go to their Wiki pages.

SR I-Go
I_go.jpgI_go_w.jpg
The SR I-Go was the Imperial Japanese Army's second Amphibious tank design, the prototype was finished in 1934. It was a large box shaped vehicle separated into several watertight sections, this gave it the ability to stay afloat even if the hull had been penetrated in one or more places. Testing showed it was quite buoyant but it's 70hp engine was only able to propel it to a max speed of 9km/h after a long period of acceleration. The steering in water was also unreliable in anything other then calm waters. Because of these reasons development was stopped an work moved on to a new design.


SR Ro-Go
Ro_go.jpgRo_go_w.jpg
Following the failure of the SR I-Go work quickly moved onto a completely new design. It was a smaller more compact vehicle using a new Horstmann type suspension system, a boat shaped bow was used to increase acceleration and two propellers with rudders were used greatly increasing performance in water. A small amount were built in 1935 and sent to China, one of them was later captured in Manchuria by Soviet troops.

Type 2 Ka-Mi
Ka_mi.jpgKa_mi_w.jpg
The Type 2 Ka-Mi was he Imperial Japanese Navy's first amphibious tank. Based on the Imperial Japanese Army's Type 95 Ha-Go, it was heavily modified with a completely new welded hull with rubber seals making it watertight. Large hollow pontoons were attached to the front and rear to make it buoyant, the pontoons could be quickly detached by the crew from within the tank once it had reached land, sometimes they were kept attached to add an additional layer of armour but this reduced maneuverability. Production of the Ka-Mi started in 1942 after Japans initial amphibious attacks in the pacific. Soon after Japan was forced onto the defensive so the Ka-Mi was never used in it's original role, instead they were mainly used to support isolated garrison on small islands, often being dug into the ground and used as pillboxes.

Type 3 Ka-Chi
Ka_chi.jpgKa_chi_w.jpg
With the success of the Type 2 Ka-Mi the Imperial Japanese Navy started work on designing a larger vehicle with stronger armor and armament. To speed up development many parts from the new Type 1 Chi-He were used. Type 3 Ka-Chi entered service in late 1943 but by 1944 Japan was on the defensive and there were no planes for future amphibious assaults so production of the Ka-Chi was a very low priority, only 19 were built by the end of the war in 1945.

Type 4 Ka-Tsu
Ka_tsu.jpgKa_tsu_w.jpg
Experiences during the beginning of the war showed that landing craft were quite vulnerable to attack and were not suited to resupplying Japanese garrisons on smaller island that were cut off from supply. So in 1943 work started on an armored amphibious cargo tractor that could be transported by submarine to the besieged islands. The prototype was ready by the end of 1943 and was tested until March 1944. Soon after plans were made to use the Ka-Tsu to attack Allied ships anchored in atolls that were protected by the outer reefs. The Ka-Tsu however could simply drive over the reef and then back into the water on the other side to attack the now vulnerable ships. Several vehicles were modified and successfully tested but the war ended before the plan could be carried out.

Type 5 To-Ku
To_ku.jpgTo_ku_w.jpg
A further development of the Type 3 Ka-Chi, the To-Ku used an improved sloped armour layout to increase protection. The 47mm Type 1 cannon was moved from the turret to the hull and replaced with a 25mm Type 95 gun. The front pontoon was lowered so the 47mm cannon & the bow machine gun could be used while it was in water. Some sources state that a single prototype was completed before the war but no photographic evidence has been found.

I'm going to take a break from units for awhile and work on some new terrain and maps next, so look out for that in a week or two.
