Spaced Armor
Armour with two or more plates spaced a distance apart falls under the category of spaced armour. Spaced armour can be sloped or unsloped. When sloped, it reduces the penetrating power of bullets and solid shot, as after penetrating each plate projectiles tend to tumble, deflect, deform, or disintegrate; spaced armour that is not sloped is generally designed to provide protection from explosive projectiles, which detonate before reaching the primary armour. Spaced armour is used on military vehicles such as tanks and combat bulldozers. In a less common application, it is used in some spacecraft that use Whipple shields. Against kinetic penetrators The first spaced armour was used on iron and steel warships from the mid-19th century. Between the thin outer armour of various less important parts and the thick main armour (protecting turrets, ammunition depots, boilers and turbines) were constructed storage spaces, coal or oil bunkers, and so on ( Lord Nelson class). Some ships (e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
PTRD-41
The PTRD-41 (Shortened from Russian, ''ProtivoTankovoye Ruzhyo Degtyaryova''; ''Противотанковое однозарядное ружьё системы Дегтярёва образца 1941 года''; "Degtyaryov Single Shot Anti-Tank Weapon System Model of 1941") was an anti-tank rifle produced and used from early 1941 by the Soviet Red Army during World War II. It was a single-shot weapon which fired a 14.5×114 mm round, which was able to penetrate German tanks such as the Panzer III and early models of the Panzer IV. Although unable to penetrate the frontal armor of late-war German tanks, it could penetrate their thinner side armor at close ranges as well as thinly armored self-propelled guns and half-tracks. History In 1939, in its invasion of Poland the USSR captured several hundred Polish Model 35 anti-tank rifles, which had proved effective against the German invasion of Poland from the West. Vasily Degtyaryov copied its lock and several features of the Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-72
The T-72 is a family of Soviet/Russian main battle tanks that entered production in 1969. The T-72 was a development of the T-64, which was troubled by high costs and its reliance on immature developmental technology. About 25,000 T-72 tanks have been built, and refurbishment has enabled many to remain in service for decades. It has been widely exported and has seen service in 40 countries and in numerous conflicts. The T-90 introduced in 1992 is a development of the T-72B; production and development of various modernized T-72 models continues today. Development Development from the T-64 The T-72 was a product of a rivalry between design teams. Morozov KB was led by Alexander Morozov in Kharkiv. Uralvagon KB was led by Leonid Kartsev in Nizhny Tagil. To improve on the T-62, two designs based on the tank were tested in 1964: Nizhny Tagil's Object 167 (T-62B) and Kharkiv's Object 434. Ob. 434 was a technically ambitious prototype. Under the direction of Morozov in Kharkiv, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Centurion (tank)
The Centurion was the primary British Army main battle tank of the post-World War II period. Introduced in 1945, it is widely considered to be one of the most successful post-war tank designs, remaining in production into the 1960s, and seeing combat into the 1980s. The chassis was adapted for several other roles, and these variants have remained in service. It was a very popular tank with good armour, manoeuvrability, and armament. Development of the Centurion began in 1943 with manufacture beginning in January 1945. Six prototypes arrived in Belgium less than a month after the war in Europe ended in May 1945. It entered combat with the British Army in the Korean War in 1950 in support of the UN forces. The Centurion later served on the Indian side in the Indo-Pakistani War of 1965, where it fought against US-supplied M47 and M48 Patton tanks, and it served with the Royal Australian Armoured Corps in the Vietnam War. Israel's army used Centurions in the 1967 Six-Day War, t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alvis Saladin
The FV601 Saladin is a six-wheeled armoured car developed by Crossley Motors and later manufactured by Alvis. Designed in 1954, it replaced the AEC Armoured Car in service with the British Army from 1958 onward. The vehicle weighed 11 tonnes, offered a top speed of 72 km/h, and had a crew of three. Saladins were noted for their excellent performance in desert conditions, and found favour with a number of Middle Eastern armies accordingly.''Middle East Economic Digest (1968)''. Collard, Elizabeth, Volume 12 pp. 131—173. They were armed with a 76 mm low-pressure rifled gun which fired the same ammunition as that mounted on the FV101 Scorpion. The Saladin also spawned an armoured personnel carrier counterpart, the Alvis Saracen. Despite the vehicle's age and dated design, it is still in use in a number of countries in secondary roles. History Development Following the end of the Second World War, the British Army issued a requirement for a new, 6×6 wheeled armoured v ...

Shipunov 2A42
The Shipunov 2A42 is a Soviet/Russian 30 mm autocannon. It is built by the Tulamashzavod Joint Stock Company. Design The 30 mm 2A42 autocannon was developed as a replacement for 2A28 Grom and has a dual feed. One is for HE-T and the other for AP-T rounds. The gunner can select one of two rates of full automatic fire, low at 200 to 300 rds/min and high at 550 to 800 rds/min.

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
T-34
The T-34 is a Soviet medium tank introduced in 1940. When introduced its 76.2 mm (3 in) tank gun was less powerful than its contemporaries while its 60-degree sloped armour provided good protection against Anti-tank warfare, anti-tank weapons. The Christie suspension was inherited from the design of American J. Walter Christie's M1928 tank, versions of which were sold turret-less to the Red Army and documented as "farm tractors", after being rejected by the U.S. Army. The T-34 had a profound effect on the conflict on the Eastern Front (World War II), Eastern Front in the World War II, Second World War, and had a short lasting impact on tank design. After the Germans encountered the tank in 1941 during Operation Barbarossa, German general Paul Ludwig Ewald von Kleist called it "the finest tank in the world" and Heinz Guderian affirmed the T-34's "vast superiority" over German tanks. Alfred Jodl, chief of operations staff of the German armed forces noted in his war diar ... [...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] |
Lunge Mine
The Shitotsubakurai ( ja, 刺突爆雷) lunge mine was a suicidal anti-tank weapon developed and used by the Empire of Japan during the Second World War. It used a HEAT type charge. This weapon was used by the CQC units of the Imperial Japanese Army. The weapon itself was a conical hollow charge anti-tank mine, placed inside a metallic container and attached to the end of a wooden stick. The weapon was officially adopted by the Japanese Army in 1945; in that year it caused its first victims in the Pacific Theater, where it commonly saw action against American armour. Later that year, some Japanese Imperial Army manuals of the weapon were discovered by US troops. Design The weapon itself was a conical hollow charge attached to one end of the weapon, which was a wooden stick used to hold the weapon during its transport and use. The mine had three equally spaced legs facing forward around the conical explosive base of the weapon. The detonator of the weapon was situated at the en ...

Panzerwurfmine
The ''Panzerwurfmine'' (abbreviated to PWM) was a shaped charge hand-thrown anti-tank grenade used by ''Luftwaffe'' ground troops in World War II. Appearance The ''Panzerwurfmines appearance owed much to the ''Panzerfaust'' (specifically its warhead), which was of similar construction and operation. The major difference was that the PWM had a tube attached to the charge, running behind it, with some form of stabilising fins or canvas attached to the rear of the tube. Premise For any high-explosive anti-tank mine or grenade to be effective against armour, it must sit squarely on to the armour, so that the high-velocity jet of metal punches through the armour at a ninety degree angle. A way of making sure this happens is to place the charge onto the armour by hand. However, this puts the participant into grave danger from defensive fire from the tank and other enemies. A thrown version would be more versatile, but it would be hard to ensure the ninety degree angle. The ''Panzerwurf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hafthohlladung
The ''Hafthohlladung'', also known as the "''Panzerknacker''" ("tank breaker", German connotation "safe cracker"), was a magnetically adhered, shaped charge anti-tank grenade used by German forces in World War II, and was sometimes described as a mine. Details The ''Hafthohlladung'' (lit. "adhesive hollow charge") was primarily used by ''Wehrmacht'' tank killer squads. Designed with three magnets at the base, each with a pair of poles creating a strong magnetic field across their gap, an infantryman could attach it to an enemy's tank no matter the angle of the surface. As the blast axis should be flush and perpendicular to the plane of the armour at the point of placement, and armed by pulling the igniter on the rear of the mine, the degree of a tank's sloped armour was irrelevant for the device's penetration. However, since this required direct placement on an enemy tank by an infantryman, using the device was very dangerous, since the deploying infantryman placing it on an en ...
