O-I
O-I was the name given to a proposed series of Japanese super-heavy tanks, to be used in the Pacific Theater. The vehicle was planned to be very heavy and have a crew of 11. The complete history of the O-I is unknown, due to the “obscure” nature of the project and the limited documentation known to have survived post-war. History and development After the Battles of Khalkhin Gol against the Soviet Union in 1939, Japan tried to improve their tank designs using lessons learned from this battle. Many Japanese tanks such as the Type 95 Ha-Go light tank and the Type 97 Chi-Ha medium tanks were proven to be insufficient to counter Soviet armored forces. A larger tank design was urgently needed. A super heavy tank project was proposed directly in response to the Japanese defeat at Khalkhin Gol. In early 1940, Hideo Iwakuro, a colonel with the Army Ministry of Japan (陸軍省 Rikugun-shō) ordered the Army Engineering Division to develop a new super heavy tank. Colonel Iwakuro indi ...

Super-heavy Tank
A super-heavy tank or super heavy tank is any tank that is notably beyond the standard of the class heavy tank in either size or weight relative to contemporary vehicles. Programs have been initiated on several occasions with the aim of creating an extremely resilient vehicle for penetrating enemy formations without fear of being destroyed in combat; however, only a few examples were built, and there is little evidence of any super heavy tank having seen combat. Examples were designed in the First and Second World Wars, along with a few during the Cold War. History First World War left, Model of the Flying Elephant design The first super-heavy tank was designed by the Russian naval engineer Vasily Mendeleyev who worked on the project from 1911 to 1915. The tank was envisioned to be invulnerable to almost all contemporary threats but remained on paper due to its high construction cost. Following the production of their first tanks, the British "Flying Elephant" was desig ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Empire Of Japan
The also known as the Japanese Empire or Imperial Japan, was a historical nation-state and great power that existed from the Meiji Restoration in 1868 until the enactment of the post-World War II 1947 constitution and subsequent formation of modern Japan. It encompassed the Japanese archipelago and several colonies, protectorates, mandates, and other territories. Under the slogans of and following the Boshin War and restoration of power to the Emperor from the Shogun, Japan underwent a period of industrialization and militarization, the Meiji Restoration, which is often regarded as the fastest modernisation of any country to date. All of these aspects contributed to Japan's emergence as a great power and the establishment of a colonial empire following the First Sino-Japanese War, the Boxer Rebellion, the Russo-Japanese War, and World War I. Economic and political turmoil in the 1920s, including the Great Depression, led to the rise of militarism, nationa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Type 5 Chi-Ri
The ("Imperial Year 2605 Medium Tank Model 9") was a medium tank developed by the Imperial Japanese Army in World War II. It was intended to be a heavier, more powerful version of Japan's prototype Type 4 Chi-To medium tank. Only one incomplete prototype was built. History and development Based on battlefield information from the Eastern Front, the Department of Army Weaponry published a report demanding a shift of tank design focus from infantry-support tanks to tanks specialised for anti-tank missions. The Army's requirements for the new medium tank were an increase of weight from 20 tonnes to 35 tonnes and an armour upgrade from 50 mm to 75 mm. The new tank would be mounted with a new 75 mm tank gun instead of the previous 57 mm tank gun. Production focus would also prioritise quality over quantity. The new medium tank was designated as Type 5 Medium Tank Chi-Ri (五式中戦車 チリ). A single unarmed prototype of the Type 5 Chi-Ri was completed by May ...

Iroha
The is a Japanese poem. Originally the poem was attributed to the founder of the Shingon Esoteric sect of Buddhism in Japan, Kūkai, but more modern research has found the date of composition to be later in the Heian period (794–1179). The first record of its existence dates from 1079. It is famous because it is a perfect pangram, containing each character of the Japanese syllabary exactly once. Because of this, it is also used as an ordering for the syllabary, in the same way as the ''A'', ''B'', ''C'', ''D''... sequence of the Latin alphabet. Text The first appearance of the Iroha, in was in seven lines: six with seven morae each, and one with five. It was also written in man'yōgana. 以呂波耳本部止 千利奴流乎和加 餘多連曽津祢那 良牟有為能於久 耶万計不己衣天 阿佐伎喩女美之 恵比毛勢須 Structurally, however, the poem follows the standard 7–5 pattern of Japanese poetry (with one hypometric line), and in modern times it is g ...

Hideo Iwakuro
was a major general in the Imperial Japanese Army during World War II. He is also known as one of the founders of the Kyoto Sangyo University. Biography Early career Iwakuro was born on Kurahashi-jima in the Inland Sea (then part of Aki County, Hiroshima prefecture). Although he grew up on the island neighboring Etajima (where the Imperial Japanese Naval Academy was located), Iwakuro had no interest in a naval career, and was sent for schooling to a military academy in Nagoya. He graduated from the 30th class of the Imperial Japanese Army Academy in 1918, and was assigned to the 16th Infantry Regiment, based at Shibata city in the Hokuetsu region of Japan. In September 1920, Iwakuro's regiment was assigned as part of the Japanese expeditionary force participating in the Siberian Intervention, and Iwakuro participated in numerous combat missions against Bolshevik partisans.

Type 95 Heavy Tank
The Type 95 heavy tank was the final result of Japanese multi-turreted tank design, and was in commission during the time period between World War I and World War II. Modeled on German and Italian tank designs, this tank featured 3 turrets. The main armament being a 70 mm cannon in a central turret, with its secondary front turret mounting a 37 mm gun and a 6.5 mm machine gun in the rear turret. Four prototypes were produced in 1934. History After World War I, major powers around the world quickly adopted the revolutionary design of French Renault FT light tank. One of the most successful features on the Renault FT was a 360 degree rotating turret. While developing new single-turreted tanks more closely based on the Renault FT, many countries, including Japan, also experimented with the possibility of multi-turreted designs.

Type 97 Chi-Ha
The was a medium tank used by the Imperial Japanese Army during the Second Sino-Japanese War, the Battles of Khalkhin Gol against the Soviet Union, and the Second World War. It was the most widely produced Japanese medium tank of World War II. The 57 mm main gun, designed for infantry support, was a carry over from the Type 89 I-Go medium tank. The suspension was derived from the Type 95 Ha-Go light tank, but used six road wheels instead of four. The 170 hp Mitsubishi air cooled diesel engine was a capable tank engine in 1938. The Type 97's low silhouette and semicircular radio antenna on the turret distinguished the tank from its contemporaries. After 1941, the tank was less effective than most Allied tank designs. In 1942, a new version of the Chi-Ha was produced with a larger three-man turret, and a high-velocity Type 1 47 mm tank gun. It was designated the Type 97-Kai or Type 97 ''Shinhōtō Chi-Ha'' ( ja, 新砲塔チハ; "New turret Chi-Ha"). History and devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
