24 Cm Haubitze 39
The 24 cm houfnice vz.39 (German designation: 24 cm Haubitze 39) (Howitzer model 39) was a Czechoslovak-designed siege howitzer used in the Second World War. It was kept in production after the German occupation of Czechoslovakia in March 1939 and eighteen were delivered to the Germans. It was only used by the Army's ''Artillery Regiment 814'' and entered service shortly before the Battle of France in 1940. The regiment participated Operation Barbarossa and in the Sieges of Sevastopol and Leningrad. Description and development Škoda designed it for export and Turkey ordered a batch, but only received two before the Germans occupied Czechoslovakia in March 1939. It was a stablemate of the Škoda 21 cm Kanone 39 and used virtually the same mounting and transport arrangements. It used an interrupted screw breech with a de Bange obturator to provide the gas seal with bagged propellant. The carriage revolved on a ball-race firing platform that had to be dug-in befo ...

Siege Of Leningrad
The siege of Leningrad (russian: links=no, translit=Blokada Leningrada, Блокада Ленинграда; german: links=no, Leningrader Blockade; ) was a prolonged military blockade undertaken by the Axis powers against the Soviet city of Leningrad (present-day Saint Petersburg) on the Eastern Front of World War II. Germany's Army Group North advanced from the south, while the German-allied Finnish army invaded from the north and completed the ring around the city. The siege began on 8 September 1941, when the Wehrmacht severed the last road to the city. Although Soviet forces managed to open a narrow land corridor to the city on 18 January 1943, the Red Army did not lift the siege until 27 January 1944, 872 days after it began. The blockade became one of the longest and most destructive sieges in history, and it was possibly the costliest siege in history due to the number of casualties which were suffered throughout its duration.

Artillery Of Czechoslovakia
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 - ...

World War II Artillery 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. '' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Army Group North
Army Group North (german: Heeresgruppe Nord) was a German strategic formation, commanding a grouping of field armies during World War II. The German Army Group was subordinated to the ''Oberkommando des Heeres'' (OKH), the German army high command, and coordinated the operations of attached separate army corps, reserve formations, rear services and logistics, including the Army Group North Rear Area. Operational history The Army Group North was created on the 2 September 1939 by reorganization of the 2nd Army Headquarters. Commander in Chief as of 27 August 1939 was Field Marshal Fedor von Bock. Invasion of Poland The first employment of Army Group North was in the invasion of Poland of 1939, where in September it controlled: * 3rd Army * 4th Army * a reserve of four divisions ** 10th Panzer Division ** 73rd Infantry Division ** 206th Infantry Division ** 208th Infantry Division. The Army Group was commanded by Fedor von Bock for the operation. After the end of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
11th Army (Wehrmacht)
The 11th Army (german: 11. Armee) was a World War II field army. History The 11th Army was established on 5 October 1940 as "Kommandostab Leipzig", but changed its designation to Kommandostab München on 23 April 1941. It was restructured into Heeresgruppe Don on 21 November 1942. After being reformed on 26 January 1945 and taking part in various counter-offensives against the Soviet and US advance, the army surrendered to American troops on 23 April 1945. Formation The 11th Army was activated in 1940 to prepare for the forthcoming German attack on the Soviet Union. The 11th Army was part of Army Group South when it invaded the USSR during Operation Barbarossa. In September 1941, Erich von Manstein was appointed its commander. His predecessor, Colonel-General Eugen Ritter von Schobert, perished when his Fieseler Storch aircraft landed in a Soviet minefield.

Army Group South
Army Group South (german: Heeresgruppe Süd) was the name of three German Army Groups during World War II. It was first used in the 1939 September Campaign, along with Army Group North to invade Poland. In the invasion of Poland Army Group South was led by Gerd von Rundstedt and his chief of staff Erich von Manstein. Two years later, Army Group South became one of three army groups into which Germany organised their forces for Operation Barbarossa. Army Group South's principal objective was to capture Soviet Ukraine and its capital Kiev. In September 1944, the Army Group South Ukraine was renamed Army Group South in Eastern Hungary. It fought in Western Hungary until March 1945 and retired to Austria at the end of the Second World War, where it was renamed Army Group Ostmark on 2 April 1945. Operation Barbarossa Ukraine was a major center of Soviet industry and mining and had the good farmland required for Hitler's plans for ''Lebensraum'' ('living space'). Army Group So ...

1st Panzer Group
The 1st Panzer Army (german: 1. Panzerarmee) was a German tank army that was a large armoured formation of the Wehrmacht during World War II. When originally formed on 1 March 1940, the predecessor of the 1st Panzer Army was named Panzer Group Kleist (''Panzergruppe Kleist'') with Colonel General Ewald von Kleist in command. Service history Panzer Group Kleist was the first operational formation of several Panzer corps in the Wehrmacht. Created for the Battle of France on 1 March 1940; it was named after its commander Ewald von Kleist. Panzer Group Kleist played an important role in the Battle of Belgium. Panzer corps of the Group broke through the Ardennes and reached the sea, forming a huge pocket, containing several Belgian, British, and French armies. When the armistice was signed, the Group was deployed in occupied France, being renamed to Panzer Group 1 (''Panzergruppe 1'') in November. In April 1941, Panzer Group 1 took part in the invasion of Yugoslavia as part of Fi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Army Group B
Army Group B (German: ') was the title of three German Army Groups that saw action during World War II. Operational history Army Group B first took part in the Battle of France in 1940 in Belgium and the Netherlands. The second formation of Army Group B was established when Army Group South was divided for the summer offensive of 1942 on the Eastern Front. Army Group B was given the task of protecting the northern flank of Army Group A, and included the 6th Army during the Battle of Stalingrad. In February 1943, Army Group B and Army Group Don were combined to create a new Army Group South. A new Army Group B was formed in northern Italy under Field Marshal Erwin Rommel in July 1943. Its task was to secure Northern Italy after the overthrow of Mussolini and to disarm the Italian Army there as part of Operation Achse. After the stabilisation of the front on the Winter Line south of Rome by Kesselring's Army Group C, and the creation of the Salo Republic in Northern It ...

Driving Band
Russian 122 mm shrapnel shell, which has been fired, showing rifling marks on the copper driving band around its base and the steel bourrelet nearer the front A driving band or rotating band is a band of soft metal near the base of an artillery shell, often made of gilding metal, copper, or lead. When the shell is fired, the pressure of the propellant swages the metal into the rifling of the barrel and forms a seal; this seal prevents the gases from blowing past the shell, and engages the barrel's rifling to spin-stabilize the shell. Purpose The rotating band has three essential functions: * Center the rear end of the projectile in the gun barrel. * Seal the bore to prevent burning powder gas from moving through the rifling grooves past the projectile. * Engage with the rifling of the barrel to spin the projectile and stabilize its flight. Characteristics The shell is stabilized for yaw in the barrel by a smaller bourrelet band near the front of the projectile. This b ...

Copper
Copper is a chemical element with the symbol Cu (from la, cuprum) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable metallic form ( native metals). This led to very early human use in several regions, from circa 8000 BC. Thousands of years later, it was the first metal to be smelted from sulfide ores, circa 5000 BC; the first metal to be cast into a shape in a mold, c. 4000 BC; and the first metal to be purposely alloyed with another metal, tin, to create ...

Explosive Material
An explosive (or explosive material) is a reactive substance that contains a great amount of potential energy that can produce an explosion if released suddenly, usually accompanied by the production of light, heat, sound, and pressure. An explosive charge is a measured quantity of explosive material, which may either be composed solely of one ingredient or be a mixture containing at least two substances. The potential energy stored in an explosive material may, for example, be * chemical energy, such as nitroglycerin or grain dust * pressurized gas, such as a gas cylinder, aerosol can, or BLEVE * nuclear energy, such as in the fissile isotopes uranium-235 and plutonium-239 Explosive materials may be categorized by the speed at which they expand. Materials that detonate (the front of the chemical reaction moves faster through the material than the speed of sound) are said to be "high explosives" and materials that deflagrate are said to be "low explosives".
