Type 98 20 Mm AAG Tank
The Type 98 20 mm AAG (anti-air gun) tank was a Japanese self-propelled anti-aircraft gun using a twin Soki Type II 20 mm anti-air gun. They were combined with the chassis of the Type 98 Ke-Ni. The gun crew worked from a raised platform with a modest amount of protection from the sides - the twin 20 mm gun fired through a large gun shield gave further protection for the crew from that direction. In November 1941, development began on an anti-aircraft version of the Type 98 with a 20 mm AA gun. During development of the AA gun tank, the Imperial Japanese Army experimented with various configurations. Single gun variant An earlier produced single gun prototype was designated the ''Type 98 Ta-Se'' anti-aircraft tank, in November 1941. The name was taken from ''taikū'' ('anti-air') ''sensha'' ('tank'). It was equipped with a single converted Type 98 20 mm AA machine cannon in a circumferential turret. During trials, it was determined that the chassis used for the ... [...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] |
Bell Crank
A bellcrank is a type of crank that changes motion through an angle. The angle can be any angle from 0 to 360 degrees, but 90 degrees and 180 degrees are most common. The name comes from its first use, changing the vertical pull on a rope to a horizontal pull on the striker of a bell, used for calling staff in large houses or commercial establishments. Angles A typical 90 degree bellcrank consists of an "L" shaped crank pivoted where the two arms of the L meet. Moving rods (or cables or ropes) are attached to the ends of the L arms. When one is pulled, the L rotates around the pivot point, pulling on the other arm. A typical 180 degree bellcrank consists of a straight bar pivoted in the center. When one arm is pulled or pushed, the bar rotates around the pivot point, pulling or pushing on the other arm. Mechanical advantage Changing the length of the arms changes the mechanical advantage of the system. Many applications do not change the direction of motion but instead amplify a ...

Type 2 20 Mm AA Machine Cannon
The Type 2 20 mm AA machine cannon was a Japanese-designed anti-aircraft gun, based on the assembly of the German Flak 38. It entered service in 1942. Design Introduced in 1942, compared to the earlier Type 98 20 mm AA machine cannon, Type 2 20 mm had higher maximum rate of fire, could be elevated to 95 degrees and had a central fire-control system. The central fire-control system developed for the Type 2 could control and direct six of the guns at once. The gun was based on the German 2 cm Flak 30/38/Flakvierling. The Type 2 number was designated for the year the gun was accepted, 2602 in the Japanese imperial year calendar, or 1942 in the Gregorian calendar.War Department TM-E-30-480 ''Handbook on Japanese Military Forces'', September 1944, p. 400. Variant Two of the guns mounted together formed a variant known as the Type 2 20 mm twin AA machine cannon.

Self-propelled Anti-aircraft Gun
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir-S1). Platforms used include both trucks and heavier combat vehicles such as armored personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, missiles (generally mounted on similar turrets) have largely supplanted anti-aircraft guns, but they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Type 98 Ke-Ni
The or Type 98A Ke-Ni Ko (also known as Type 98 Chi-Ni light tank) was designed to replace the Imperial Japanese Army's Type 95 Ha-Go light tank, Japan's most numerous armored fighting vehicle during World War II. Although designed before World War II began, production did not start until 1942, with 104 being produced by the end of the war in the Pacific. History and development The Type 98 developed in 1938 was a light tank with the same weight as the earlier Type 95 Ha-Go, but with thicker armor. The first prototype was originally known as the "Chi-Ni Model A" and completed by Hino Motors. The second prototype was originally known as the "Chi-Ni Model B" (a/k/a the "Type 98B Ke-Ni Otsu") and completed by Mitsubishi. This second experimental model had a different suspension system with four larger road-wheels, similar to the US Christie suspension design. During field trials the "Model A" demonstrated superior performance, especially in off-road capabilities, so the Hino design ...

Gun Shield
A U.S. Marine manning an M240 machine gun equipped with a gun shield A gun shield is a flat (or sometimes curved) piece of armor designed to be mounted on a crew-served weapon such as a machine gun, automatic grenade launcher, or artillery piece. Military Some mounted machine guns and artillery pieces are equipped with metal armor plates to protect the gunners from small arms fire and shrapnel from explosions. They were fitted to some armored fighting vehicles and patrol boats during the Vietnam War. Gun shields fell out of widespread use after the Vietnam war, but they have seen a resurgence in popularity during the 1990s. Israeli military analysts began urging the use of gun shields, pointing to the grave risk to soldiers exposed to fire from automatic weapons. In particular, it was noted that many casualties were hit in areas not protected by body armor or a helmet, such as the neck or face. The U.S. began using gun shields during the 2000s-era wars in Iraq and Afghanista ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Japanese Army
The was the official ground-based armed force of the Empire of Japan from 1868 to 1945. It was controlled by the Imperial Japanese Army General Staff Office and the Ministry of the Army, both of which were nominally subordinate to the Emperor of Japan as supreme commander of the army and the Imperial Japanese Navy. Later an Inspectorate General of Aviation became the third agency with oversight of the army. During wartime or national emergencies, the nominal command functions of the emperor would be centralized in an Imperial General Headquarters (IGHQ), an ad hoc body consisting of the chief and vice chief of the Army General Staff, the Minister of the Army, the chief and vice chief of the Naval General Staff, the Inspector General of Aviation, and the Inspector General of Military Training. History Origins (1868–1871) In the mid-19th century, Japan had no unified national army and the country was made up of feudal domains (''han'') with the Tokugawa shogunate (''bakufu ...

Type 98 20 Mm AA Half-track Vehicle
The Type 98 20 mm AA half-track vehicle was an experimental Japanese self-propelled anti-aircraft gun. It had a single 20 mm Type 98 AA cannon mounted on the back section of a Type 98 four-ton half-track. The modified vehicle used was designated the Type 98 half-tracked prime mover Ko-Hi. The Type 98 Ko-Hi was first manufactured in 1938 by Isuzu. The Type 98 four-ton vehicles were "high speed" prime movers, capable of when loaded. Average transport time was 10 hours road time for .
