5 cm Pak 38
The 5 cm Pak 38 (L/60) (''5 cm Panzerabwehrkanone 38 (L/60)'') was a German anti-tank gun of 50 mm calibre. It was developed in 1938 by Rheinmetall-Borsig AG as a successor to the 3.7 cm Pak 36, and was in turn followed by the 7.5 cm Pak 40. Note the unique curved gun-shield design which differs from most WWII anti-tank guns which have either one flat or two angled and one flat gun-shield plates for ease of manufacturing. Successor to the Pak 36 After the Spanish Civil War, the German authorities started to think that a new anti-tank gun would be needed, even though the 3.7 cm Pak 36 had proven to be very successful. They asked Rheinmetall-Borsig to produce a new and more capable AT-gun. They first designed the Pak 37 in 1935, but the German authorities did not approve it because of its low capabilities. Rheinmetall-Borsig were forced to create a new gun under the designation Pak 38, which fitted a new and longer L/60 barrel and was approved for mass producti ...

Tunisian Campaign
The Tunisian campaign (also known as the Battle of Tunisia) was a series of battles that took place in Tunisia during the North African campaign of the Second World War, between Axis and Allied forces from 17 November 1942 to 13 May 1943. The Allies consisted of British Imperial Forces, including a Greek contingent, with American and French corps. The battle opened with initial success by the German and Italian forces but the massive supply interdiction efforts led to the decisive defeat of the Axis. Over 250,000 German and Italian troops were taken as prisoners of war, including most of the Afrika Korps. Background Western Desert The first two years of the war in North Africa were characterized by chronic supply shortages and transport problems. The North African coast has few natural harbors and the British base at Alexandria on the Nile delta was some by road from the main Italian port at Tripoli in Libya. Smaller ports at Benghazi and Tobruk were and west of Alexan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5 Cm KwK 38
The 5 cm KwK 38 L/42 ''(5 cm Kampfwagenkanone 38 L/42)'' was a German 50 mm calibre cannon used as the main armament of variants of the German Sd.Kfz. 141 Panzerkampfwagen III medium tank during the Second World War. (The towed anti-tank gun equivalent was the PaK.37 of which 2,600 were produced from 1937 until 1940). History The Panzer III was intended to fight other tanks; in the initial design stage a gun was specified. However, the infantry at the time were being equipped with the PaK 36, and it was thought that, in the interest of standardization, the tanks should carry the same armament. As a compromise, the turret ring was made large enough to accommodate a gun should a future upgrade be required. This single decision later assured the Panzer III a prolonged life in the German Army.Perrett (1999), p. 4. The early Panzer III Ausf. A to early Ausf. G were equipped with a 3.7 cm KwK 36 L/45, which proved adequate during the campaigns of 1939 and 1940. In r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War II Anti-tank Guns Of Germany
In its most general sense, the term "world" refers to the totality of entities, to the whole of reality or to everything that is. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of many parts. In ''scientific cosmology'' the world or universe is commonly defined as " e totality of all space and time; all that is, has been, and will be". '' Theories of modality'', on the other hand, talk of possible worlds as complete and consistent ways how things could have been. ''Phenomenology'', starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In ''philosophy of mind'', the world is commonly contrasted with the mind as that which is represented by the mind. ''Th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
57 Mm Anti-tank Gun M1943 (ZiS-2)
The ZiS-2 (russian: ЗиС-2) (GRAU index: 52-P-271) is a Soviet Union, Soviet 57 mm anti-tank gun used during World War II. The ZiS-4 is a version of the gun that was meant to be installed in tanks. ''ZiS'' stands for ''Zavod imeni Stalina'' (Russian ''Завод имени Сталина'', 'Factory named after Joseph Stalin, Stalin'), the official title of Artillery Factory No. 92, which produced the gun first. Development In the beginning of 1940 the design office of Vasily Grabin, V. G. Grabin received a task from the artillery department to develop a powerful anti-tank gun. The head of this department, Marshal Grigory Kulik, Kulik, and his subordinates estimated that the use of heavily armoured tanks by the USSR in the Winter War would not have gone unnoticed in Nazi Germany and would lead to the development of similar fighting machines there. There is also a chance that the department was influenced by German propaganda about the experimental multi-turreted "supertank" Ne ...

Romanian Armed Forces
The Land Forces, Air Force and Naval Forces of Romania are collectively known as the Romanian Armed Forces ( ro, Forțele Armate Române or ''Armata Română''). The current Commander-in-chief is Lieutenant General Daniel Petrescu who is managed by the Minister of National Defence while the president is the Supreme Commander of the Armed Forces during wartime. As of 2021, the Armed Forces number 68,500 active personnel and 53,000 reserves. The Land Forces have a reported strength of 35,800, the Air Force 10,700, the Naval Forces 6,600, and Joint Forces 16,500, in 2020. Total defence spending currently accounts for 2.02% of total national GDP, which represents approximately 5.7 billion US dollars. The Armed Forces are built for territorial defence, with contributions to NATO missions such as in Afghanistan a secondary priority. As of 2022, Romania is ranked 38 of 140 out of the countries considered for the annual GFP review. History of the Romanian Armed Forces The first att ...

Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term and was the manifestation of the Nazi regime's efforts to rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Nazi rise to power in 1933, one of Adolf Hitler's most overt and audacious moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi régime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and defense spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military power. In the early part of the Second World War, the ''Wehrmacht'' employed combined arms tactics (close-cover ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
KV-1 (tank)
The Kliment Voroshilov (KV) tanks are a series of Soviet heavy tanks named after the Soviet defence commissar and politician Kliment Voroshilov who operated with the Red Army during World War II. The KV tanks were known for their heavy armour protection during the early stages of the war, especially during the first year of the German invasion of the Soviet Union. In certain situations, even a single KV-1 or KV-2 supported by infantry could halt German formations. The German ''Wehrmacht'' at that time rarely deployed its tanks against KVs, as their own armament was too poor to deal with the "''Russischer Koloss''" – "Russian Colossus". The KV tanks were practically immune to the 3.7 cm KwK 36 and howitzer-like, short-barreled 7.5 cm KwK 37 guns mounted, respectively, on the early Panzer III and Panzer IV tanks fielded by the invading German forces. Until the Germans developed more effective guns, the KV-1 was invulnerable to almost any German weapon except the 8.8 cm Flak gun ...

Tungsten Carbide
Tungsten carbide (chemical formula: WC) is a chemical compound (specifically, a carbide) containing equal parts of tungsten and carbon atoms. In its most basic form, tungsten carbide is a fine gray powder, but it can be pressed and formed into shapes through sintering for use in industrial machinery, cutting tools, chisels, abrasives, armor-piercing shells and jewelry. Tungsten carbide is approximately twice as stiff as steel, with a Young's modulus of approximately 530–700 GPa, and is double the density of steel—nearly midway between that of lead and gold. It is comparable with corundum (α-) in hardness and can be polished and finished only with abrasives of superior hardness such as cubic boron nitride and diamond powder, wheels and compounds. Naming Historically referred to as Wolfram, ''Wolf Rahm'', wolframite ore was then later carburized and cemented with a binder creating a composite now called "tungsten carbide". Tungsten is Swedish for "heavy stone". Col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armor-piercing Ammunition
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 armour w ...

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] |
Operation Barbarossa
Operation Barbarossa (german: link=no, Unternehmen Barbarossa; ) was the invasion of the Soviet Union by Nazi Germany and many of its Axis allies, starting on Sunday, 22 June 1941, during the Second World War. The operation, code-named after Frederick Barbarossa ("red beard"), a 12th-century Holy Roman emperor and German king, put into action Nazi Germany's ideological goal of conquering the western Soviet Union to repopulate it with Germans. The German aimed to use some of the conquered people as forced labour for the Axis war effort while acquiring the oil reserves of the Caucasus as well as the agricultural resources of various Soviet territories. Their ultimate goal was to create more (living space) for Germany, and the eventual extermination of the indigenous Slavic peoples by mass deportation to Siberia, Germanisation, enslavement, and genocide. In the two years leading up to the invasion, Nazi Germany and the Soviet Union signed political and economic pacts for st ...

Second World War
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
