O-I Super- and Ultra-heavy Tanks.  Both types of tanks were still in active service in 1940, and additional vehicles and spare parts were obtained after the Japanese occupation of French Indochina. â¦ At the time of this request, the biggest tank in Japan was the modest Type 95 Heavy Tank. âO-Iâ was the chosen designation for a series of proposed super-heavy tanks to be used by the Japanese in the Pacific War. , The Type 1 was an early IJN experimental design that led to the Type 2 Ka-Mi, which was based on the Type 95 Ha-Go light tank.  Eventually, an 88 mm gun (based on the Type 99 88 mm AA Gun) was planned for the turret; a secondary weapon of a front hull-mounted Type 1 37 mm tank gun was fitted in the position normally taken by a machine gun. , The Type 4 medium tank Chi-To (四式中戦車 チト, Yonshiki chūsensha Chi-To) was one of several new medium and heavy tanks developed by the Imperial Japanese Army towards the end of World War II. âO-Iâ was the chosen designation for a series of proposed super-heavy tanks to be used by the Japanese in the Pacific War. A team of engineers of the Technical Bureau participated in the development, including a young army officer, Major Tomio Hara. Adolf Hitler was a proponent of "war winning" weapons and supported projects like the 188 tonne Maus, and even larger 1,000 tonne Landkreuzer P. 1000 Ratte. The gun was a 105mm with a relatively short barreled gun. However, the newer tanks were not available as these countries had difficulties supplying them to their own armored forces, and the only available model was the older Renault FT. The Japanese reluctantly imported the Renault FT tanks. According to Hara, the first tank on the agenda was to develop a medium main battle tank.  The tank had a Type 97 heavy tank machine gun mounted in the hull and a ball mount on the side of the turret for a second one. The Japanese super-tank of WWII, it would have had a crew of 11 & weighed 100 tons.  Another variant known as the Type 2 Ke-To light tank, began production in 1944. On 22 December 1941 the Type 95 light tank earned the distinction of being the first tank to engage in tank vs tank combat with US manned American tanks (M3 Stuart light tanks in the Philippines) during World War II; and the only enemy tanks to have ever landed on North American soil during any war. However, the development of the Type 4 Chi-To was delayed, and a "stopgap tank" was needed. Nevertheless, the Japanese must have still seen some value in the multi-turret tank concept for their O-I tanks and continued in their design. Only one prototype was built.  The designation is also known as the Type 89 "I-Go" and sometimes transliterated "Yi-Go". The model is placed in a small diorama with 3 figures. 0.1 Super Heavy Tank Military Modelcraft International | August 2019. This set is the O-I in full color using Green, Tan and Reddish Brown parts. General Suzuki (chief of the Technical Bureau) protested at the Ministry of War decision to purchase foreign designs, which ultimately led to that decision being reversed. A special committee of the Imperial General Staff (Daihonei) worked on the feasibility of indigenous design and development of Japanese armor. , The Type 3 Chi-Nu medium tank was urgently developed to counter the American M4 Sherman medium tank. In 1939 Japanese officials began studying super heavy tanks based on the multi-turret design that was popular during the 1930s. , Even though the Hino Motors "Chi-Ni Model A" prototype was accepted after field trials as the new Type 98 light tank, series production did not begin until 1942. , Type 95 Ha-Go tanks served during the Battle of Khalkhin Gol (Nomonhan) against the Soviet Red Army in 1939, against the British Army in Burma and India, and throughout the Pacific Theater during World War II. The low priority given tanks, along with the raw material shortages meant that the Type 3 did not enter production until 1944.

The weight of the initial prototype and its low speed did not impress the Imperial Japanese Army General Staff Office, so a new requirement was issued for a lighter tank, with a nominal 10-short-ton (9.1-metric-ton) weight. The Japanese O-I experimental super heavy tank had three turrets and weighed 120 tons, more than any of the German Tiger tanks, but less than the 188 ton Maus or rival 140 ton E-100.. The newer tank proved to be superior to the Type 97 in design, speed and armor protection. One thing I noticed looking at the kit instructions is if you want to model the kit with the outboard track assembly in the towing configuration you will need to box in each side. IX Type 4 Heavy. The O-I (Oi-sensha) was a super-heavy tank prototype designed by the Imperial Japanese Army during the Second Sino-Japanese War after the Battles of Nomonhan in 1939. , In addition, the terrain of Southeast Asia and the islands of the Pacific were in general not suited to armored warfare, being largely tropical rainforests. This means adding more armour would not increase protection to any significant degree, and thus current development is instead focused on a combination of remaining undetected, interfering with tracking and active counter-measures to neutralize the enemy weapon systems.  A total of 104 Type 98s are known to have been built: 1 in 1941, 24 in 1942 and 79 in 1943. "Ultra Heavy Tank": Modification of the O-I Super Heavy Tank with four turrets.

In March 1927, the IJA also bought a Vickers Medium C to use for design study. The first had 2 12 cylinder BMW marine engines, with a not functionally cooling system.  As with many innovative weapons projects launched by Japan in the final months of World War II, production could not advance due to material shortages, and the loss of Japan's industrial infrastructure to the allied bombing of Japan. Aside from the invasion of Malaya, and the Philippines, large-scale Japanese use of tanks was limited during the early years of the war and therefore development of newer designs were not given high priority as the Japanese strategy shifted to a "defensive orientation" after the 1941-42 victories. The Type 95 weighed 7.4 tons and had three crewmen. Since mobility was more important than protection, and the tanks already developed were successful, work on the project was stopped.

With their defeat by the Soviet Union at Nomonhan in 1939, the Japanese began to rethink their tank designs and doctrine, although their emphasis would continue to remain on supporting the infantry. The Japanese Maus.  Following the production of their first tanks, the British "Flying Elephant" was designed as a tank that would be resistant to artillery fire. A larger tank design was urgently needed. However, due to the recent HESH nerf, I am unsure whether Type-60 is still a viable option. By 1944, total production of tanks and AFV's had fallen to 925 and for 1945, only 256 were produced. II Ashigaru Te-Ke.
