T2 Tank
The T2 Medium Tank was an American design that replaced three prototype medium tank designs started in the 1920s for an experiment conducted by the United States Army. The T2 tank never saw combat nor left prototype stages and due to lack of funds was not mass-produced with only one built in 1930 by Rock Island Arsenal. Its legacy, however, was the M2 light tank, developed into the M2 medium, and onto the M3 Lee and M4 Sherman medium tanks. Design Following the testing of the Medium Tank M1921 two new medium tank projects were approved in 1926, one of which was for a lighter 15 ton tank design. The first design, armed with a gun in the hull front and a smaller gun in the turret, did not progress due to lack of funding and instead the Light Tank T1E1 was used as a basis. The design of the T2 was largely inspired by the British Vickers Medium Mark II and was later developed into the M2 light tank. When the T2 Medium Tank was built, its weight had to be reduced drastically b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

T1 Light Tank
The Light Tank, T1 was a United States Army light tank of the late 1920s and early 1930s that was only built in prototype form. The tank was an Army design built by James Cunningham, Son and Company. Introduced in 1927, it was developed up through 1932 as a series of modified versions (T1E1, T1E2, T1E3, T1E4, T1E5, and T1E6). The tank was never mass-produced, nor was it ever used in combat. Design and variants Most versions of the T1 series of light tanks shared the same basic layout, with the engine mounted in the front and the turret, transmission and final drive all located in the rear. The exceptions were the T1E4 and T1E6, which moved the turret to the middle, the engine to the rear, and the transmission and final drive to the front, a configuration similar to later tanks. All T1 versions had a manually traversed turret armed with a 37 mm () main gun and a coaxially mounted .30 caliber (7.62 mm) M1919 Browning machine gun, and all carried a crew of two: a comman ...

Interwar Tanks Of The United States
In the history of the 20th century, the interwar period lasted from 11 November 1918 to 1 September 1939 (20 years, 9 months, 21 days), the end of the First World War to the beginning of the Second World War. The interwar period was relatively short, yet featured many significant social, political, and economic changes throughout the world. Petroleum-based energy production and associated mechanisation led to the prosperous Roaring Twenties, a time of both social mobility and economic mobility for the middle class. Automobiles, electric lighting, radio, and more became common among populations in the developed world. The indulgences of the era subsequently were followed by the Great Depression, an unprecedented worldwide economic downturn that severely damaged many of the world's largest economies. Politically, the era coincided with the rise of communism, starting in Russia with the October Revolution and Russian Civil War, at the end of World War I, and ended with the rise o ...

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vickers Medium Mark II
The Vickers Medium Mark II was a British tank built by Vickers in the Inter-war period. The Medium Mark II, derived from the Vickers Medium Mark I, was developed to replace the last of the Medium Mark Cs still in use. Production and rebuilding ran from 1925 until 1934. The tank was phased out of service from 1939, replaced by the Cruiser Mk I. It featured several improvements over the Vickers Mark I: a higher superstructure with the driver's visor on top of it instead of in front of it; an improved suspension protected by armour skirts; and Rackham clutches, providing a primitive form of mechanical servo-control. Due to a slightly higher weight its rated speed was somewhat slower than that of the Medium Mark I, at compared to . Design The Mark II used the same chassis, suspension and transmission as the Medium Mark I but had a new superstructure. The Mark II was equipped with a 47 mm 3 pdr gun and four machine guns in the turret. The back of the turret had a slope so that ...

Medium Tank M1921
The Medium Tank M1921 was a medium tank built in the United States in the inter-war period. In design, it was similar to earlier WW1 era tanks. United States Army engineers worked on the design of the tank, with some influence from British designs of the period, and from the earlier war experience. One example was produced. The tank was an early example of a turreted US tank, less usual at the time, with the turret housing the main gun, with the tank also possessing two machine guns for defence. Development The United States Army developed the tank with the idea that the US could produce a locally produced tank, and not rely on British or French technology, who were some of the main producers and exporters of tanks at the time. The tank was produced at the Rock Island Arsenal. The biggest problem was the engine, which was meant to provide horsepower of at 1,200 rpm, but in fact generated less than that. The engine was later replaced with a Liberty L-12 engine, and then a later a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M4 Sherman
} The M4 Sherman, officially Medium Tank, M4, was the most widely used medium tank by the Military history of the United States during World War II, United States and Allies of World War II, 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 Armoured_fighting_vehicle, armored fighting vehicles including self-propelled artillery, Tank_destroyer, tank destroyers, and Armoured_recovery_vehicle, armored recovery vehicles. Tens of thousands were distributed through the Lend-Lease program to the British Empire#Second World War, British Commonwealth and Soviet Union. The tank was named by the British after the American Civil War General William Tecumseh Sherman. The M4 Sherman evolved from the M3 Lee, M3 Medium Tank, which for speed of development had its main armament in a side sponson mount. The M4 retained much of the previous mechanical design, but moved the 75_mm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M3 Lee
The M3 Lee, officially Medium Tank, M3, was an American medium tank used during World War II. The turret was produced in two forms, one for US needs and one modified to British requirements to place the radio next to the commander. In British Commonwealth service, the tank was called by two names: tanks employing US pattern turrets were called "Lee," named after Confederate general Robert E. Lee, while those with British pattern turrets were known as "Grant," named after Union general Ulysses S. Grant. Design commenced in July 1940, and the first M3s were operational in late 1941. The US Army needed a medium tank armed with a 75mm gun and, coupled with the United Kingdom's immediate demand for 3,650 medium tanks, the Lee began production by late 1940. The design was a compromise meant to produce a tank as soon as possible. The M3 had considerable firepower and good armor, but had serious drawbacks in its general design and shape, including a high silhouette, an archaic sponson ...
