M18 Hellcat
The M18 Hellcat (officially designated the 76 mm Gun Motor Carriage M18 or M18 GMC) is a tank destroyer used by the United States Army in World War II and the Korean War. Despite being equipped with the same main gun as some variants of the much larger M4 Sherman, Sherman tank, the M18 attained a much higher top speed of up to by keeping armor to a minimum, and using the innovative Hydramatic, Torqmatic automatic transmission. The M18 Hellcat was the culmination of the development of various prototypes of fast tank destroyers dating back to 1941. Entering production in summer 1943, the M18 first saw combat service in spring 1944. The M18 served primarily in Western Front (World War II), Western Europe, but was also present in smaller numbers in Italian campaign (World War II), Italy and the Asiatic-Pacific Theater, Pacific. Production continued until October 1944, with 2,507 built. This tank was the most effective U.S. tank destroyer of World War II. It had a higher kill- ...

Tank Destroyer
A tank destroyer, tank hunter or tank killer is a type of armoured fighting vehicle, predominantly intended for anti-tank duties. They are typically armed with a direct fire anti-tank gun, artillery gun, also known as a self-propelled anti-tank gun, or missile launcher, also called an anti-tank missile carrier. The vehicles are designed specifically to engage and destroy enemy tanks, often with limited operational capacities. While tanks are designed for front-line combat, combining operational mobility and Military tactics, tactical offensive and defensive capabilities and performing all primary tasks of the armoured troops, the tank destroyer is specifically designed to take on enemy tanks and other armoured fighting vehicles. Many are based on a Continuous track, tracked tank chassis, while others are wheeled. Since World War II, gun-armed powerful tank destroyers have fallen out of favor as armies have favored multirole main battle tanks. However, lightly armoured Anti-ta ...

Ordnance QF 6-pounder
The Ordnance quick-firing 6-pounder 7 cwt,British forces traditionally denoted smaller ordnance by the weight of its standard projectile, in this case approximately . The approximate weight of the gun barrel and breech, "7 cwt" (cwt = hundredweight), was included in the designation to distinguish this gun from others also firing a 6 lb projectile. or just 6-pounder, was a British 57 mm gun, serving during the Second World War as a primary anti-tank gun of both the British and United States Army (as the 57 mm gun M1). It was also used as the main armament for a number of armoured fighting vehicles. Although designed before the start of the war, it did not reach service until the North African Campaign in April 1942, where it replaced the 2-pounder as an anti-tank gun, allowing the 25-pounder gun-howitzer to revert to its intended artillery role. Development and production Development Limitations of the existing 2-pounders were apparent even as the gun entered se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M22 Locust
The M22 Locust, officially Light Tank (Airborne), M22, was an American-designed airborne light tank which was produced during World War II. The Locust began development in 1941 after the British War Office requested that the American government design a purpose-built airborne light tank which could be transported by glider into battle to support British airborne forces. The War Office had originally selected the Light Tank Mark VII Tetrarch light tank for use by the airborne forces, but it had not been designed with that exact purpose in mind so the War Office believed that a purpose-built tank would be required to replace it. The United States Army Ordnance Department was asked to produce this replacement, which in turn selected Marmon-Herrington to design and build a prototype airborne tank in May 1941. The prototype was designated the Light Tank T9 (Airborne), and was designed so that it could be transported underneath a Douglas C-54 Skymaster transport aircraft; its dimen ...

Radial Engine
The radial engine is a reciprocating engine, reciprocating type internal combustion engine, internal combustion engine configuration in which the cylinder (engine), cylinders "radiate" outward from a central crankcase like the spokes of a wheel. It resembles a stylized Star polygon, star when viewed from the front, and is called a "star engine" in some other languages. The radial configuration was commonly used for aircraft engines before gas turbine engines became predominant. Engine operation Since the axes of the cylinders are coplanar, the connecting rods cannot all be directly attached to the crankshaft unless mechanically complex forked connecting rods are used, none of which have been successful. Instead, the pistons are connected to the crankshaft with a master-and-articulating-rod assembly. One piston, the uppermost one in the animation, has a master rod with a direct attachment to the crankshaft. The remaining pistons pin their connecting rods' attachments to rings ar ...

Christie Suspension
The Christie suspension is a suspension system developed by American engineer J. Walter Christie for his tank designs. It allowed considerably longer movement than conventional leaf spring systems then in common use, which allowed his tanks to have considerably greater cross-country speed. The system was first introduced on his M1928 design, and used on all of his designs until his death in 1944. History Christie advocated the use of lightweight tanks with long range and high speed, designed to penetrate enemy lines and attack their infrastructure and logistics capabilities. A major problem with tanks in World War I was tracked suspension failure. Christie's first tank design of 1919 could be driven on its wheels to get to the starting point and then the tracks fitted before it went into action. The US Tank Corps ordered a single tank from Christie's company based on this design. The tank, known as the M1919, was delivered in early 1921 and tested until Christie propos ...

M3 Stuart
The M3 Stuart/light tank M3, was a US light tank of World War II, first entered service in the British Army in early 1941 and saw action in the North African campaign in July 1941. Later an improved version of the tank entered service as the M5 in 1942 to be supplied to British and other allied Commonwealth forces under lend-lease prior to the entry of the United States into the war. The British service name "Stuart" came from the U.S. Civil War Confederate general J. E. B. Stuart and was used for both the M3 and the derivative M5 light tank. Unofficially, they were also often called "Honeys" by the British, because of their smooth ride. In U.S. use, the tanks were officially known as "light tank M3" and "light tank M5". Stuarts were first used in combat in the North African campaign; about 170 were used by the British forces in Operation Crusader (18 November – 30 December 1941). Stuarts were the first American-crewed tanks in World War II to engage the enemy in tank v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

M36 Gun Motor Carriage
The M36 tank destroyer, formally 90 mm Gun Motor Carriage, M36, was an American tank destroyer used during World War II. The M36 combined the hull of the M10 tank destroyer, which used the M4 Sherman's reliable chassis and drivetrain combined with sloped armor, and a new turret mounting the 90 mm gun M3. Conceived in 1943, the M36 first served in combat in Europe in October 1944, where it partially replaced the M10 tank destroyer. It also saw use in the Korean War, where it was able to defeat any of the Soviet tanks used in that conflict. Some were supplied to South Korea as part of the Military Assistance Program and served for years, as did re-engined examples found in Yugoslavia, which operated into the 1990s. Two remained in service with the Republic of China Army at least until 2001. The vehicle is also known by the nickname ''General Jackson'', or just ''Jackson'', which was originally assigned to the vehicle by the Ordnance Department in November 1944 for publicity ...

M10 Gun Motor Carriage
The M10 tank destroyer, formally known as 3-inch gun motor carriage M10 or M10 BBC, was an American tank destroyer of World War II. After US entry into World War II and the formation of the Tank Destroyer Force, a suitable vehicle was needed to equip the new battalions. By November 1941, the Army requested a vehicle with a gun in a fully rotating turret after other interim models were criticized for being too poorly designed. The prototype of the M10 was conceived in early 1942 and delivered in April that year. After appropriate changes to the hull and turret were made, the modified version was selected for production in June 1942 as the "3-inch Gun Motor Carriage M10". It mounted the 3-inch (76.2 mm) gun M7 in a rotating turret on a modified M4 Sherman tank chassis. It was built in two variants. The M10 GMC used the M4A2 Sherman chassis and the M10A1 used the M4A3 chassis. Production of the two models ran from September 1942 to December 1943 and October 1942 to November 194 ...
