Type 1 Chi-He
The was an improved version of the Type 97 Chi-Ha medium tanks of the Imperial Japanese Army in World War II. It had a more powerful main gun, engine and thicker armor. It was the first Japanese tank to have a communication radio as standard equipment. Production of the tank did not begin until 1943, due to the higher priority of steel allocated to the Imperial Navy for warship construction. A total of 170 units were built. All of the tanks produced were allocated for the defense of the Japanese home islands, against the anticipated Allied Invasion. History and development After 1941, the Imperial Japanese Army quickly realized that its 1930s designed medium tank, the Type 97 Chi-Ha, was inferior to the 1940s generation of Allied armor, such as the M4 Sherman. Since the Type 97’s low-velocity 57 mm main gun was designed for infantry support in 1938, it could not penetrate the 1940s generation of Allied armor, whereas its own thin armor made the Type 97 vulnerable to m ...

Medium Tank
A medium tank is a classification of tanks, particularly prevalent during World War II which represented a compromise between the mobility oriented light tanks and the armour and armament oriented heavy tanks. A medium tank's classification is not actually based on weight, but off of tactical usage and intended purpose; for instance the German Panzerkampfwagen V Panther medium tank has a mass similar to contemporary Allied heavy tanks. The most widely produced, cost effective and successful tanks of World War II (the German Panzer IV, the Soviet T-34, and the American M4 Sherman) were all medium tank designs. Many of the medium tank lines became what are called main battle tanks in most countries. History The first tanks to carry the name "Medium" appeared in the First World War with the British Medium Mark A Whippet. It was smaller, lighter and faster than the British heavy tanks of the time and only carried machine guns. The medium tank doctrine came into use in the interwa ...

Self-propelled Gun
Self-propelled artillery (also called locomotive artillery) is artillery equipped with its own propulsion system to move toward its firing position. Within the terminology are the self-propelled gun, self-propelled howitzer, self-propelled mortar, and rocket artillery. They are high mobility vehicles, usually based on continuous tracks carrying either a large field gun, howitzer, mortar, or some form of rocket/missile launcher. They are usually used for long-range indirect bombardment support on the battlefield. In the past, self-propelled artillery has included direct-fire vehicles, such as assault guns and anti-tank guns (tank destroyers). These have been armoured vehicles, the former providing close fire-support for infantry and the latter acting as specialized anti-tank vehicles. Modern self-propelled artillery vehicles often mount their main gun in a turret on a tracked chassis so they superficially resemble tanks. However they are generally lightly armoured which ...

Type 3 75 Mm Tank Gun
The Type 3 75 mm tank gun was used as the main armament of the Imperial Japanese Army Type 3 Chi-Nu medium tank. It was one of the largest guns ever to be fitted on a World War II Japanese tank. Design and use The Type 3 had a caliber of , barrel length of (L/38). As fitted to the Type 3 Chi-Nu medium tank, elevation was from -10 to +25 degrees. Firing a shell at a muzzle velocity of it gave an armor penetration of at and at . It shot a 6.6 kilogram projectile. This gun was based on the Japanese Type 90 field gun which in turn was loosely based on the French Schneider et Cie ''Canon de 85 mle 1927''. The Type 3 gun was license-built by the Osaka Arsenal. The Type 3 Chi-Nu, in which the gun was mounted, was the most powerful tank in regular series production for the Imperial Japanese Army during World War II. The Type 3 Chi-Nu was developed to cope with the M4 Sherman. By 1943, the low priority given to tank production meant that the Type 3 did not actually enter productio ...

Gun Turret
A gun turret (or simply turret) is a mounting platform from which weapons can be fired that affords protection, visibility and ability to turn and aim. A modern gun turret is generally a rotatable weapon mount that houses the crew or mechanism of a projectile-firing weapon and at the same time lets the weapon be aimed and fired in some degree of azimuth and elevation (cone of fire). Description Rotating gun turrets protect the weapon and its crew as they rotate. When this meaning of the word "turret" started being used at the beginning of the 1860s, turrets were normally cylindrical. Barbettes were an alternative to turrets; with a barbette the protection was fixed, and the weapon and crew were on a rotating platform inside the barbette. In the 1890s, armoured hoods (also known as "gun houses") were added to barbettes; these rotated with the platform (hence the term "hooded barbette"). By the early 20th Century, these hoods were known as turrets. Modern warships have gu ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Suspension (vehicle)
Suspension is the system of tires, tire air, springs, shock absorbers and linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/ handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. It is important for the suspension to keep the road wheel in contact with the road surface as much as possible, because all the road or ground forces acting on the vehicle do so through the contact patches of the tires. The suspension also protects the vehicle itself and any cargo or luggage from damage and wear. The design of front and rear suspension of a car may be different. History An early form of suspension on ox-drawn carts had the platform swing on iron chains attached to the wheeled frame of the carriage. This system remained the basis for most suspension systems until the turn of the 19th century, although the iron cha ...

Type 3 Chi-Nu
was a medium tank of the Imperial Japanese Army in World War II. Like the Type 1 Chi-He, this tank was an improved version of the Type 97 Chi-Ha. It incorporated a Type 3 75 mm tank gun, one of the largest Japanese tank guns during the war. The Chi-Nu did not see combat during the war. All produced units were retained for the defense of the Japanese Homeland in anticipation of an Allied invasion. History and development At the outbreak of the Pacific War, the Type 97 Chi-Ha medium tank and Type 95 Ha-Go light tank designs comprised the mainstay of the armored units of the Imperial Japanese Army. As the war progressed, these tanks started to face significant challenges posed by Allied tanks. In the Burma and Philippines Campaigns, the firepower of the 57 mm cannon mounted on the Type 97 was proven to be insufficient against Allied tanks. The Imperial Japanese Army therefore developed the Type 1 47 mm tank gun, which used a lighter high-explosive round with greater armo ...

Signal Flag
Flag signals can mean any of various methods of using flags or pennants to send signals. Flags may have individual significance as signals, or two or more flags may be manipulated so that their relative positions convey symbols. Flag signals allowed communication at a distance before the invention of radio and are still used especially in connection with ships. Flaghoist signalling Flaghoist signalling is one or more flags (or pennants) simultaneously flying from a fixed halyard, and generally any method of signaling by such means. Each of the flags has a distinct shape and color combination. Each flag or combination of flags has a preassigned meaning or "code". The International Code of Signals defines a standard set of flags and associated alphabet suitable for international use, as well as a set of standard codes. Flaghoist is also used in boat racing, to warn of impending severe weather, and other specialized applications. Maritime flag signalling has a long history, espe ...

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Type 3 Ka-Chi
The was an amphibious medium tank developed by the Imperial Japanese Navy in World War II. The Type 3 Ka-Chi was based on an extensively modified Imperial Japanese Army Type 1 Chi-He medium tank (it had 2 more road-wheels and two more return rollers on each side) and was a larger and more capable version of the earlier Type 2 Ka-Mi amphibious tank. History and development The success of the Type 2 Ka-Mi design pleased the planners in the Imperial Japanese Navy General Staff, and it was determined that a larger version with stronger armor and armament would be useful in future amphibious warfare operations. The Type 3 Ka-Chi prototype was completed in late 1943 and the first units entered service that same year. However, only 12 to 19 Type 3 Ka-Chi's were built from 1943 to 1945. The main priorities of the Japanese Navy were in warship and aircraft production, and lacking in any definite plans for additional amphibious operations, production of the Type 3 Ka-Chi remained a very l ...
