7TP
The 7TP (''siedmiotonowy polski'' - 7-tonne Polish) was a Polish light tank of the Second World War. It was developed from the British Vickers 6-ton. A standard tank of the Polish Army during the 1939 Invasion of Poland, its production did not exceed 150 vehicles. Its chassis was used as the base for the C7P artillery tractor. Design The 7TP was the Polish development of the British Vickers 6-ton Mark E tank licence. Comparing to Vickers, the main new features of 7TP were: a better, more reliable and powerful diesel engine, a 37 mm anti-tank gun, thicker armour (17 mm instead of 13 mm on the front), modified ventilation, the Gundlach tank periscope, and a radio. About 132 tanks were produced between 1935 and the outbreak of the war, plus four iron prototypes. The designation 7TP meant "7 Tonne, Polish" (in fact its weight increased to 9 tonnes after the initial prototype). Although 7TP is often claimed to be the world's first (production) diesel-powered tank, thi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Invasion Of Poland
The invasion of Poland (1 September – 6 October 1939) was a joint attack on the Republic of Poland by Nazi Germany and the Soviet Union which marked the beginning of World War II. The German invasion began on 1 September 1939, one week after the signing of the Molotov–Ribbentrop Pact between Germany and the Soviet Union, and one day after the Supreme Soviet of the Soviet Union had approved the pact. The Soviets invaded Poland on 17 September. The campaign ended on 6 October with Germany and the Soviet Union dividing and annexing the whole of Poland under the terms of the German–Soviet Frontier Treaty. The invasion is also known in Poland as the September campaign ( pl, kampania wrześniowa) or 1939 defensive war ( pl, wojna obronna 1939 roku, links=no) and known in Germany as the Poland campaign (german: Überfall auf Polen, Polenfeldzug). German forces invaded Poland from the north, south, and west the morning after the Gleiwitz incident. Slovak military forces ad ...

Vickers 6-ton
The Vickers 6-ton tank or Vickers Mark E, also known as the "Six-tonner" was a British light tank designed as a private project at Vickers. It was not adopted by the British Army, but was picked up by many foreign armed forces. It was licensed by the Soviet Union as the T-26. It was also the direct predecessor of the Polish 7TP tank. History The first Mark E was built in 1928 by a design team that included the famed tank designers John Valentine Carden and Vivian Loyd. The hull was made of riveted steel plates, thick at the front and over most of the turrets, and about thick on the rear of the hull. The power was provided by an Armstrong Siddeley engine of (depending on the version), which gave it a top speed of on roads. The Horstmann suspension used two axles, each of which carried a two-wheel bogie to which a second set of bogies was connected with a leaf spring. Upward movement of either set of bogies would force the other down through the spring. This was cons ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Państwowe Zakłady Inżynierii
The Państwowe Zakłady Inżynierii (''National Engineering Works'', PZInż) was a Polish pre-World War II arms industry holding and the main Polish manufacturer of vehicles, both military and civilian. History It was created by the Polish minister of industry Eugeniusz Kwiatkowski on 19 March 1928 from several previously-existing state-owned factories and scientific institutes, among them the Centralne Warsztaty Samochodowe and the Ursus factory. It was Kwiatkowski's plan of reorganization and modernization of Polish arms industry that eventually led to the creation of PZInż, but also the Państwowe Wytwórnie Uzbrojenia (''National Arms Works''), Państwowe Zakłady Lotnicze (modern PZL), Państwowe Zakłady Optyczne (''National Optical Works'') and ''National Factory of Gunpowder and Explosives'' in Pionki. Production On 21 September 1932 the National Engineering Works signed a license agreement with Italian automobile manufacturer Fiat. Soon afterwards, assembly and ...

Gundlach Periscope
The Gundlach Periscope, usually known under its British designation as Vickers Tank Periscope MK.IV, was a revolutionary invention by Polish engineer Rudolf Gundlach, manufactured for Polish 7TP tanks from the end of 1935 and patented in 1936 as the ''Peryskop obrotowy Gundlacha''. It was the first device to allow the tank commander to have a 360-degree view from his gun turret, turret with a single periscope. By rotating the periscope and allowing the tank commander to look backwards through the second eyepiece, he no longer had to change position to look behind the turret. Early tanks had small turrets and fixed seating, without an independently rotating cupola, and so the commander wasn't easily able to move himself to another rear-facing periscope. On 14 June 1935 it was officially adopted by the Polish Army, as reversible periscope G wz. 34. The design was first used in the TKS tankette, then in 7TP light tank. Shortly before the war it was given to the United Kingdom, Britis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polish Army
The Land Forces () are the land forces of the Polish Armed Forces. They currently contain some 62,000 active personnel and form many components of the European Union and NATO deployments around the world. Poland's recorded military history stretches back a millennium – since the 10th century (see List of Polish wars and History of the Polish Army). Poland's modern army was formed after Poland regained independence following World War I in 1918. History 1918–1938 When Poland regained independence in 1918, it recreated its military which participated in the Polish–Soviet War of 1919–1921, and in the two smaller conflicts ( Polish–Ukrainian War (1918–1919) and the Polish–Lithuanian War (1920)). Initially, right after the First World War, Poland had five military districts (1918–1921): * Poznań Military District (Poznański Okręg Wojskowy), HQ in Poznań * Kraków Military District (Krakowski Okręg Wojskowy), HQ in Kraków * Łódź Military District (� ...

Light Tank
A light tank is a tank variant initially designed for rapid movements in and out of combat, to outmaneuver heavier tanks. It is smaller in size with thinner armor and a less powerful main gun, tailored for better tactical mobility and ease of transport and logistics. They are primarily employed in the screening, armored reconnaissance, skirmishing, artillery observation, and supplementing landing operations in a fire support role of expeditionary forces where larger, heavier tanks are unavailable or have difficulties operating safely or efficiently. The fast light tank was a major feature of the pre-World War II army buildup, where it was expected they would be used to exploit breakthroughs in enemy lines created by slower, heavier tanks, with the goal of disrupting communications and supply lines. Numerous small tank designs and " tankettes" were developed during this period and known under a variety of names, including the " combat car". Early light tank designs were ...

Bofors Wz
AB Bofors ( , , ) is a former Swedish arms manufacturer which today is part of the British arms concern BAE Systems. The name has been associated with the iron industry and artillery manufacturing for more than 350 years. History Located in Karlskoga, Sweden, the company originates from the hammer mill "Boofors", which was founded as a royal state-owned company in 1646. The modern corporate structure was created in 1873 with the foundation of Aktiebolaget (AB) Bofors-Gullspång. The Bofors Works was acquired by Johan Eberhard Geijer in 1762. It was then acquired by the latter's brother, Emanuel af Geijerstam. A leading Swedish steel producer by the early 1870s, when steel began to be used for gun manufacture in Sweden, Bofors initially sold cast and forged steel produced by the Siemens-Martin process to Finspång gun works, but soon started to expand into weapons manufacture. The company's first cannon workshop was opened in 1884. Bofors' most famous owner was Alfred ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Battle Of Drzewica
A battle is an occurrence of combat in warfare between opposing military units of any number or size. A war usually consists of multiple battles. In general, a battle is a military engagement that is well defined in duration, area, and force commitment. An engagement with only limited commitment between the forces and without decisive results is sometimes called a skirmish. The word "battle" can also be used infrequently to refer to an entire operational campaign, although this usage greatly diverges from its conventional or customary meaning. Generally, the word "battle" is used for such campaigns if referring to a protracted combat encounter in which either one or both of the combatants had the same methods, resources, and strategic objectives throughout the encounter. Some prominent examples of this would be the Battle of the Atlantic, Battle of Britain, and Battle of Stalingrad, all in World War II. Wars and military campaigns are guided by military strategy, wherea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kingdom Of Romania
The Kingdom of Romania ( ro, Regatul României) was a constitutional monarchy that existed in Romania from 13 March ( O.S.) / 25 March 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I of Romania and the Romanian parliament's proclamation of the Romanian People's Republic. From 1859 to 1877, Romania evolved from a personal union of two vassal principalities (Moldavia and Wallachia) under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), when it also received Northern Dobruja in exchange for the southern part of Bessarabia. The kingdom's territory during the reign of King Carol I, between 13 ( O.S.) / 25 March 1881 and 27 September ( O.S.) / 10 October 1914 is sometimes refer ...
