Chi-Nu Production Line
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 Mainland Japan, Japanese Homeland in anticipation of an Operation Downfall, 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 Campaign, Burma and Philippines campaign (1941–1942), Philippines Campaigns, the firepower of the 57 mm cannon mounted on the Type 97 was proven to be insufficient against Allied tanks.

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 on 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 ...

Burma Campaign
The Burma campaign was a series of battles fought in the British colony of British rule in Burma, Burma as part of the South-East Asian theatre of World War II. It primarily involved forces of the Allies of World War II, Allies (mainly from the British Empire and the Republic of China (1912–49), Republic of China, with support from the United States) against the invading forces of the Empire of Japan. Imperial Japan was supported by the Thailand in World War II, Thai Phayap Army, as well as two Collaboration with Imperial Japan, collaborationist independence movements and armies. Nominally independent puppet states were established in the conquered areas and some Saharat Thai Doem, territories were annexed by Thailand. In 1942 and 1943, the international Allied force in British Raj, British India launched Burma campaign (1942–1943), several failed offensives to retake lost territories. Burma campaign 1944, Fighting intensified in 1944, and British Empire forces peaked at a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Several factors, including the type of firearm, the cartridge, and the barrel length, determine the bullet's muzzle velocity. Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''super ...

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 gun-m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Suspension (vehicle)
Suspension is the system of tires, tire air, spring (device), springs, shock absorbers and Linkage (mechanical), linkages that connects a vehicle to its wheels and allows relative motion between the two. Suspension systems must support both road holding/Automobile handling, handling and ride quality, which are at odds with each other. The tuning of suspensions involves finding the right compromise. The suspension is crucial for maintaining consistent contact between the road wheel and the road surface, as all forces exerted on the vehicle by the road or ground are transmitted through the tires' contact patches. 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 unti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Air Raids On Japan
During the Pacific War, Allies of World War II, Allied forces conducted air raids on Japan from 1942 to 1945, causing extensive destruction to the country's cities and killing between 241,000 and 900,000 people. During the first years of the Pacific War these attacks were limited to the Doolittle Raid in April 1942 and small-scale raids on Japanese military positions in the Kuril Islands from mid-1943. Strategic bombing during World War II, Strategic bombing raids began in June 1944 and continued with increasing intensity until the end of the war in August 1945. Allied naval and land-based Tactical bombing, tactical air units also attacked Japan during 1945. The United States Army Air Forces campaign against Japan began in earnest in mid-1944 and intensified during the final months of the war. While plans for attacks on the Japanese home islands had been prepared prior to the Pacific War, these could not begin until the long-range Boeing B-29 Superfortress bomber was ready for c ...

Type 4 Chi-To Medium Tank
The ("Imperial Year 2604 Medium Tank Model 7") was one of several medium tanks developed by the Imperial Japanese Army towards the end of World War II. While by far the most advanced Japanese wartime tank to reach production, industrial and material shortages resulted in only a few chassis being manufactured and only two known to be completed. Neither of the completed Type 4 Chi-To tanks saw combat use. Design The Type 4 Chi-To was a thirty-ton medium tank of all-welded construction and had maximum armor thickness of on the frontal plates. The turret was an enlarged variant of the one used on the Type 3 Chi-Nu medium tank and it carried a crew of five. The tank was long, high, and wide. The main armament was a turret-mounted long-barreled (4.23 m) Type 5 75 mm tank gun capable of being elevated between -6.5 to +20 degrees. An muzzle velocity gave it an armor penetration of at .

M4 Sherman
The M4 Sherman, officially medium tank, M4, was the medium tank most widely used by the United States and Western Allies in World War II. The M4 Sherman proved to be reliable, relatively cheap to produce, and available in great numbers. It was also the basis of several other armored fighting vehicles including self-propelled artillery, tank destroyers, and armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Commonwealth, Soviet Union, and other Allied Nations. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman tank evolved from the M3 Lee, a medium tank developed by the United States during the early years of World War II. The M3, also known by its service names "Grant" and "Lee," was characterized by a unique design that featured the main armament mounted in a side sponson. The Grant variant, used by British forces, employed a lower-profile turret ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
