T92 Howitzer Motor Carriage
The 240 mm Howitzer Motor Carriage T92 was a self-propelled howitzer developed by the United States during World War II. The same mounting with the 8-inch Gun M1 was developed as the T93. Neither was built in significant numbers and the war ended before they could be used in combat. History The towed 240 mm M1 howitzer was difficult to use due to its weight. Experience with the 155mm howitzer on the M4 chassis suggested it might be possible to mount it on the Heavy Tank T26E3 (which was formally named "Heavy Tank M26 Pershing" in March 1945) chassis, and that the 8-inch gun could also be mounted as part of a planned "Heavy Combat Team" using the same chassis. The latter was given the designation T93 Gun Motor Carriage. The chassis needed to be lengthened with addition of an extra road wheel, to give seven each side. The drive sprocket was also moved to the front. A limited production run ("limited procurement") of four pilot vehicles was ordered in March 1945, and the ...

Torsion Beam Suspension
The twist-beam rear suspension (also torsion-beam axle, deformable torsion beam or compound crank) is a type of automobile suspension based on a large H or C-shaped member. The front of the H attaches to the body via rubber bushings, and the rear of the H carries each stub-axle assembly, on each side of the car. The cross beam of the H holds the two trailing arms together, and provides the roll stiffness of the suspension, by twisting as the two trailing arms move vertically, relative to each other. Functioning The coil springs usually bear on a pad alongside the stub-axle. Often the shock is colinear with the spring forming a coil-over. In many cases the damper is also used as a restraint strap to stop the arm descending so far that the coil spring falls out through being completely unloaded. This location gives a high motion ratio compared with most suspensions, improving performance. The longitudinal location of the cross beam controls important parameters of the suspen ...

Ford GAA Engine
The Ford GAA engine is an American all-aluminum 32-valve DOHC 60-degree liquid-cooled V8 internal combustion engine with a flat plane crankshaft designed and produced by the Ford Motor Company before and during World War II. It features twin Stromberg NA-Y5-G carburetors,Berndt, p.190. dual magnetos and twin spark plugs making up a full dual ignition system, and crossflow induction. It displaces and puts out well over of torque from idle to 2,200 rpm. The factory-rated net output was at 2,600 rpm. The GAA powered several models and derivatives of the M4A3 Sherman medium tank. Development Immediately preceding World War II, Ford developed an aircraft engine similar to the Rolls-Royce Merlin. It was a 60 degree V-12 of 1,650 cubic inch displacement with cylinder bore and stroke matching the Merlin aviation engine, using an aluminum block and head; dual overhead camshafts, and four valves per cylinder. The intention of this design was to help Ford break into the anticipated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M26 Pershing
The M26 Pershing was a heavy tank/ medium tank of the United States Army. It was used in the last months of World War II during the Invasion of Germany and extensively during the Korean War. The tank was named after General of the Armies John J. Pershing, who led the American Expeditionary Force in Europe in World War I. The M26 was intended as a replacement of the M4 Sherman, but a prolonged development period meant that only a small number saw combat in Europe. Based on the criteria of firepower, mobility, and protection, US historian R. P. Hunnicutt ranked the Pershing behind the German Tiger II heavy tank, but ahead of the Tiger I heavy and Panther medium tanks. It was withdrawn in 1951 in favor of its improved derivative, the M46 Patton, which had a more powerful and reliable engine and advanced suspension. The lineage of the M26 continued with the M47 Patton, and was reflected in the new designs of the later M48 Patton and M60 Patton. Production history Development ...

Operation Downfall
Operation Downfall was the proposed Allied plan for the invasion of the Japanese home islands near the end of World War II. The planned operation was canceled when Japan surrendered following the atomic bombings of Hiroshima and Nagasaki, the Soviet declaration of war, and the invasion of Manchuria. The operation had two parts: Operation Olympic and Operation Coronet. Set to begin in November 1945, Operation Olympic was intended to capture the southern third of the southernmost main Japanese island, Kyūshū, with the recently captured island of Okinawa to be used as a staging area. In early 1946 would come Operation Coronet, the planned invasion of the Kantō Plain, near Tokyo, on the main Japanese island of Honshu. Airbases on Kyūshū captured in Operation Olympic would allow land-based air support for Operation Coronet. If Downfall had taken place, it would have been the largest amphibious operation in history, surpassing D-Day. Japan's geography made this invasion pl ...

Surrender Of Japan
The surrender of the Empire of Japan in World War II was announced by Emperor Hirohito on 15 August and formally signed on 2 September 1945, bringing the war's hostilities to a close. By the end of July 1945, the Imperial Japanese Navy (IJN) had become incapable of conducting major operations and an Allied invasion of Japan was imminent. Together with the United Kingdom and China, the United States called for the unconditional surrender of the Japanese armed forces in the Potsdam Declaration on 26 July 1945—the alternative being "prompt and utter destruction". While publicly stating their intent to fight on to the bitter end, Japan's leaders (the Supreme Council for the Direction of the War, also known as the "Big Six") were privately making entreaties to the publicly neutral Soviet Union to mediate peace on terms more favorable to the Japanese. While maintaining a sufficient level of diplomatic engagement with the Japanese to give them the impression they might be wi ...

Detroit Arsenal Tank Plant
Detroit Arsenal (DTA), formerly Detroit Arsenal Tank Plant (DATP) was the first manufacturing plant ever built for the mass production of tanks in the United States. Established in 1940 under Chrysler, the plant was owned by the U.S. government until 1996. It was designed by architect Albert Kahn. The building was designed originally as a "dual production facility", so that it could make armaments and be turned into peaceful production at war's end. Notwithstanding its name, the site was located in Warren, Michigan, Detroit's most populous suburb. History Chrysler's construction effort at the plant in 1941 was one of the fastest on record. The first tanks rumbled out of the plant before its complete construction. During World War II, the Detroit Arsenal Tank Plant built a quarter of the 89,568 tanks produced in the U.S. overall. The plant made M3 Lee tanks while the buildings were still being raised and switched to M4 Sherman tanks in 1942. The Korean War boosted production f ...

M110 Howitzer
The 8 inch (203 mm) M110 self-propelled howitzer is an American-made self-propelled artillery system consisting of an M115 203 mm howitzer installed on a purpose-built chassis. Before its retirement from US service, it was the largest available self-propelled howitzer in the United States Army's inventory; it continues in service with the armed forces of other countries, to which it was exported. Missions include general support, counter-battery fire, and suppression of enemy air defense systems. Description According to the operator's manual, the M110's typical rate of fire was three rounds per two minutes when operated at maximum speed, and one round per two minutes with sustained fire. The M110 featured a hydraulically operated rammer to automatically chamber the 200+ pound projectile. These rammers were prone to breakdown and generally slowed operation of the gun because the rammers required crews to completely lower the massive barrel before using it. Well trained ...
