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.

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 ...

United States
The United States of America (U.S.A. or USA), commonly known as the United States (U.S. or US) or America, is a country primarily located in North America. It consists of 50 states, a federal district, five major unincorporated territories, nine Minor Outlying Islands, and 326 Indian reservations. The United States is also in free association with three Pacific Island sovereign states: the Federated States of Micronesia, the Marshall Islands, and the Republic of Palau. It is the world's third-largest country by both land and total area. It shares land borders with Canada to its north and with Mexico to its south and has maritime borders with the Bahamas, Cuba, Russia, and other nations. With a population of over 333 million, it is the most populous country in the Americas and the third most populous in the world. The national capital of the United States is Washington, D.C. and its most populous city and principal financial center is New York City. Paleo-Americ ...

Rifled Artillery
Artillery is a class of heavy military ranged weapons that launch munitions far beyond the range and power of infantry firearms. Early artillery development focused on the ability to breach defensive walls and fortifications during sieges, and led to heavy, fairly immobile siege engines. As technology improved, lighter, more mobile field artillery cannons developed for battlefield use. This development continues today; modern self-propelled artillery vehicles are highly mobile weapons of great versatility generally providing the largest share of an army's total firepower. Originally, the word "artillery" referred to any group of soldiers primarily armed with some form of manufactured weapon or armor. Since the introduction of gunpowder and cannon, "artillery" has largely meant cannons, and in contemporary usage, usually refers to shell-firing guns, howitzers, and mortars (collectively called ''barrel artillery'', ''cannon artillery'', ''gun artillery'', or - a layman term - ...

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] |
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] |
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 ...

T34 Heavy Tank
The T34 Heavy Tank was an American design for a heavy tank. It evolved from the T29 Heavy Tank and T30 Heavy Tank in 1945, using the same chassis, but sporting a modified 120 mm Gun M1 anti-aircraft gun. Extra armor plating was applied to the rear of the turret bustle as a counterweight for the heavier 120mm T53 main gun. No production orders were placed for the T34, which was felt to be too heavy. Development In 1945, encounters with German heavy tanks and tank destroyers such as the Tiger II and Jagdtiger led to a new project to create a vehicle that could counter these new threats. The result were the T29, armed with a 105mm gun, and the T30 armed with a 155mm gun. Both were built around a lengthened version of the T26E3 chassis., and apart from the different use of guns and engines, they were originally almost identical. Early in 1945 the Ordnance Department began work on turning the 120mm anti-aircraft gun into a tank gun. It soon became clear that this gun would have ...

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] |
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 ...
