105 Mm Gun T5E1
The 105mm L/65 T5 was an American rifled anti-tank gun developed in 1945. The T5E1 was the main armament for several American WWII heavy tanks designs, including the T29 Heavy Tank. Development The project to develop a tank gun of 105mm (4.1 in) in caliber was first started during WWII in order to compete with increasing heavily armored German tanks. After the invasion of Europe, the Ordnance Department believed there would be a need for heavily armored tanks equipped with powerful armament to break through fortified areas. They proposed that existing M6 heavy tank prototypes be up-armored and mount the new 105mm T5E1. These modified T1E1s with the T5E1 gun in enlarged turrets (taken from the proposed T29 project) were designated M6A2E1. The M6A2E1 project did not proceed when Eisenhower rejected its use in Europe on August 18, 1944, but two M6A2E1s – without the increased armor – were used to test the armament and gun for the upcoming T29 Heavy Tank. The first model ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Tank Gun
A tank gun is the main armament of a tank. Modern tank guns are high-velocity, large-caliber artilleries capable of firing kinetic energy penetrators, high-explosive anti-tank, and cannon-launched guided projectiles. Anti-aircraft guns can also be mounted to tanks. As the tank's primary armament, they are almost always employed in a direct fire mode to defeat a variety of ground targets at all ranges, including dug-in infantry, lightly armored vehicles, and especially other heavily armored tanks. They must provide accuracy, range, penetration, and rapid fire in a package that is as compact and lightweight as possible, to allow mounting in the cramped confines of an armored gun turret. Tank guns generally use self-contained ammunition, allowing rapid loading (or use of an autoloader). They often display a bulge in the barrel, which is a bore evacuator, or a device on the muzzle, which is a muzzle brake. History World War I The first tanks were used to break through trench def ...

Shell (projectile)
A shell, in a military context, is a projectile whose payload contains an explosive, incendiary, or other chemical filling. Originally it was called a bombshell, but "shell" has come to be unambiguous in a military context. Modern usage sometimes includes large solid kinetic projectiles that is properly termed shot. Solid shot may contain a pyrotechnic compound if a tracer or spotting charge is used. All explosive- and incendiary-filled projectiles, particularly for mortars, were originally called ''grenades'', derived from the French word for pomegranate, so called because of the similarity of shape and that the multi-seeded fruit resembles the powder-filled, fragmentizing bomb. Words cognate with ''grenade'' are still used for an artillery or mortar projectile in some European languages. Shells are usually large-caliber projectiles fired by artillery, armored fighting vehicles (e.g. tanks, assault guns, and mortar carriers), warships, and autocannons. The shape ...

Armor-piercing Shell
Armour-piercing ammunition (AP) is a type of projectile designed to penetrate either body armour or vehicle armour. From the 1860s to 1950s, a major application of armour-piercing projectiles was to defeat the thick armour carried on many warships and cause damage to their lightly-armoured interiors. From the 1920s onwards, armour-piercing weapons were required for anti-tank warfare. AP rounds smaller than 20 mm are intended for lightly-armoured targets such as body armour, bulletproof glass, and lightly-armoured vehicles. As tank armour improved during World War II, anti-vehicle rounds began to use a smaller but dense penetrating body within a larger shell, firing at very high muzzle velocity. Modern penetrators are long rods of dense material like tungsten or depleted uranium (DU) that further improve the terminal ballistics. History The late 1850s saw the development of the ironclad warship, which carried wrought iron armour of considerable thickness. This armo ...

120 Mm M1 Gun
The 120 mm Gun M1 was the United States Army's standard super-heavy anti-aircraft gun during World War II and the Korean War, complementing the smaller and more mobile M2 90 mm gun in service. Its maximum altitude was about , which earned it the nickname ''stratosphere gun''. The M1 gun was used by the Army for air defense from 1944 to 1960. The 120 served primarily in static defensive roles, although it had been designed to be mobile. It became obsolete with the development of anti-aircraft missiles and was phased out after 1954. History The Army first worked on a 120 mm gun after the end of World War I, with a prototype being presented in 1924. The system was considered far too heavy and expensive to be useful, and the project slowed, although it was never canceled outright. In 1938, the Army reviewed its needs for newer AA systems and decided to order new systems for both the heavy and super-heavy role. The former was filled by the new M1 90 mm gun, which replaced ...

T30 Heavy Tank
The Heavy Tank T30 was a World War II American tank project developed to counter new German tanks, such as Tiger I, Tiger II, and tank destroyers, such as the ''Jagdtiger'', or Soviet heavy tanks, such as IS-1 or IS-2. The T30 was designed at the same time as the T29 Heavy Tank. Early tanks Plans for four pilot heavy tanks were put forward in 1944; two T29 with a 105 mm gun and two T30 with a 155 mm gun. The T30 pilot models were started in April 1945 and were delivered in 1947. Apart from modifications to fit the different engine, the chassis was the same as the T29. The gun fired separate loading (shell and charge) ammunition. The loader was assisted by a spring rammer. The T30 was fitted with one of the largest guns ever used on an American tank. The high, rounded edge, turret was needed to accommodate the standing loader and large gun mount. Even then the gun could only be loaded at limited elevations. It could carry a mixed assortment of 34 T35E1 HVAP (high-vel ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

155 Mm Gun T7
The 155mm L/41 T7 was an American rifled tank gun developed in 1945. The T7 was to be the main armament for the T30 Heavy Tank The Heavy Tank T30 was a World War II American tank project developed to counter new German tanks, such as Tiger I, Tiger II, and tank destroyers, such as the ''Jagdtiger'', or Soviet heavy tanks, such as IS-1 or IS-2. The T30 was designed at th ..., but only a handful were produced due to the T30 project being cancelled after trials in the late 1940s. The T7 used two-part separated ammunition like the 105mm T5E1 gun on the T29 Heavy Tank. It had a low velocity of only compared to the 120mm T53 on the T34 Heavy Tank (945 m/s) and the 105mm T5E1 on the T29 Heavy Tank (945 m/s). However, the 43 kg (95 lbs) High-Explosive shell was demonstrated to have a powerful demolition effect. Testing concluded before completion when the T30 project was cancelled in the late 1940s.

T28 Super Heavy Tank
The T28 Super Heavy Tank was an American heavily armored tank/self-propelled gun designed for the United States Army during World War II. It was originally designed to break through German defenses of the Siegfried Line, and was later considered as a possible participant in the planned invasion of the Japanese mainland. The near 100-ton vehicle was initially designated a heavy tank. It was re-designated as the 105 mm Gun Motor Carriage T95 in 1945, and then renamed in 1946 as the Super Heavy Tank T28. Only two prototypes were built before the project was terminated. Name Initially named Heavy Tank T28 when construction was authorized in 1944, the design did not fit in the usual categories of vehicles leading to reclassification.Hunnicutt p. 61 As it did not have its armament in a revolving turret, Ordnance requested a name change to 105 mm Gun Motor Carriage T95, the change becoming official in March 1945.Hunnicutt p. 62 However, due to its heavy armor and armament†...

Western Front (World War II)
The Western Front was a European theatre of World War II, military theatre of World War II encompassing Denmark, Norway, Luxembourg, Belgium, Netherlands, the Netherlands, the United Kingdom, France, and Germany. The Italian campaign (World War II), Italian front is considered a separate but related theater. The Western Front's 1944-1945 phase was officially deemed the European Theater of Operations, United States Army, European Theater by the United States, whereas Italy fell under the Mediterranean Theater of Operations, United States Army, Mediterranean Theater along with North Africa. The Western Front was marked by two phases of large-scale combat operations. The first phase saw the capitulation of Luxembourg, Netherlands, Belgium, and France during May and June 1940 after their defeat in the Low Countries and the northern half of France, and continued into an air war between Germany and Britain that climaxed with the Battle of Britain. The second phase consisted of large- ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

M6 Heavy Tank
The Heavy Tank M6 was an American heavy tank designed during World War II. The tank was produced in small numbers and never saw combat. Development Because of limited budgets for tank development in the interwar years, at the outbreak of World War II the United States Army possessed few tanks, though it had been keeping track of the use of tanks in Europe and Asia. Successful employment of armored units in 1939–40, mostly by the Germans, gave momentum to a number of US tank programs, including a heavy tank. The United States possessed a massive industrial infrastructure and large numbers of engineers that would allow for mass production of tanks. Following the Chief of Infantry recommendation from May 1940, the US Army Ordnance Corps started to work on a 50-ton heavy tank design. The project was approved in June and the vehicle received the designation Heavy Tank T1. Initially, a multi- turreted design was proposed, with two main turrets each armed with a low-velocity T6 ...

T29 Heavy Tank
The Heavy Tank T29 was an American heavy tank project started in March 1944 to counter the appearance of the German Tiger II heavy tank. The T29 was not ready in time for the war in Europe, but it did provide post-war engineers with opportunities for applying engineering concepts to artillery and automotive components. Development The T29 was based upon a lengthened version of the T26E3 chassis and featured heavier armor, an upgraded Ford GAC engine producing 750 hp at 2,800rpm, which gave it a power to weight ratio of 11.68 hp/t, more comfortable controls for the driver, and a massive new turret incorporating the high-velocity 105 mm gun T5, which was later replaced by a more powerful 105 mm T5E1. The tank weighed approximately unloaded and combat loaded. Its maximum armor thickness was on the turret (not including the mantlet, which was thick), compared to on the German Tiger II's turret. The turret had a turret rotation of 18 degrees per second, takin ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |
