Zakłady Mechaniczne Tarnów
Zakłady Mechaniczne Tarnów ( en, Tarnów Mechanical Works; ) is a Polish defense manufacturing company. Based in the city of Tarnów, the company produces handguns, assault rifles, sniper rifles and anti-air guns. It is part of the Bumar-Labedy corporation, itself a division of the state-controlled Polish Armaments Group. History Initially founded during World War I in 1917 as a local train repair workshop, in the interwar period the company was part of the Polish State Railways. After the company's equipment was confiscated, dismantled and sent to Germany during World War II, the factory was rebuilt as a train repair workshop, but in 1951 it was turned into a defence contractor producing guns, firearms and machine tools. Warsaw Pact years From 1951 the company license-built M1939 37 mm automatic air defense guns and Nudelman N-37 aircraft cannons used in LiM-2 and MiG-17 fighters. While Poland was still in the Warsaw Pact, other types of Soviet-designed military equipment we ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Self-propelled Anti-aircraft Gun
An anti-aircraft vehicle, also known as a self-propelled anti-aircraft gun (SPAAG) or self-propelled air defense system (SPAD), is a mobile vehicle with a dedicated anti-aircraft capability. Specific weapon systems used include machine guns, autocannons, larger guns, or missiles, and some mount both guns and longer-ranged missiles (e.g. the Pantsir-S1). Platforms used include both trucks and heavier combat vehicles such as armored personnel carriers and tanks, which add protection from aircraft, artillery, and small arms fire for front line deployment. Anti-aircraft guns are usually mounted in a quickly-traversing turret with a high rate of elevation, for tracking fast-moving aircraft. They are often in dual or quadruple mounts, allowing a high rate of fire. In addition, most anti-aircraft guns can be used in a direct-fire role against surface targets to great effect. Today, missiles (generally mounted on similar turrets) have largely supplanted anti-aircraft guns, but they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Science And Technology In Poland
Education has been of prime interest to Poland's rulers since the early 12th century. The catalog of the library of the Cathedral Chapter in Kraków dating from 1110 shows that Polish scholars already then had access to western European literature. In 1364, King Kazimierz the Great founded the Cracow Academy, which would become one of the great universities of Europe. The Polish people have made considerable contributions in the fields of science, technology and mathematics. The list of famous scientists in Poland begins in earnest with the polymath, astronomer and mathematician Nicolaus Copernicus, who formulated the heliocentric theory and made an important contribution to the scientific revolution. In 1773 King Stanisław August Poniatowski established the Commission of National Education, the world's first ministry of education. After the third partition of Poland, in 1795, no Polish state existed. The 19th and 20th centuries saw many Polish scientists working abroad. One of t ...

Armoured Fighting Vehicles Of Poland
Armour (British English) or armor (American English; see spelling differences) is a covering used to protect an object, individual, or vehicle from physical injury or damage, especially direct contact weapons or projectiles during combat, or from a potentially dangerous environment or activity (e.g. cycling, construction sites, etc.). Personal armour is used to protect soldiers and war animals. Vehicle armour is used on warships, armoured fighting vehicles, and some mostly ground attack combat aircraft. A second use of the term ''armour'' describes armoured forces, armoured weapons, and their role in combat. After the development of armoured warfare, tanks and mechanised infantry and their combat formations came to be referred to collectively as "armour". Etymology The word "armour" began to appear in the Middle Ages as a derivative of Old French. It is dated from 1297 as a "mail, defensive covering worn in combat". The word originates from the Old French , itself deri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

PZA Loara
The PZA Loara (Polish: ''Przeciwlotniczy Zestaw Artyleryjski'' or "anti-aircraft artillery system") is a Polish armored radar-directed self-propelled anti-aircraft gun system. The original PZA Loara prototype was based on the chassis of the T-72M tank. The production version known as PZA Loara-A is based on the chassis of the PT-91 MBT. Description The system was developed in Poland in the late 1990s by RADWAR S.A. in cooperation with numerous state and industry partners. Work on the project began in 1994 with an emphasis on the PZA variant of the vehicle. A working prototype was completed by the year 2000, which was subsequently submitted for live fire trials in September. It was originally planned that the LOARA program would also include a missile-armed version of the system – called the PZR Loara – a missile-armed version of the vehicle based on the PZA and sharing approx. 70% parts commonality. The PZR was ultimately canceled. Early prototypes were built on a modified ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ZSU-23-4
The ZSU-23-4 "Shilka" is a lightly armored Soviet self-propelled, radar-guided anti-aircraft weapon system (SPAAG). Etymology The acronym "ZSU" stands for ''Zenitnaya Samokhodnaya Ustanovka'' (russian: Зенитная Самоходная Установка), meaning "anti-aircraft self-propelled system"; the "23" signifies the bore diameter in millimeters; the "4" signifies the number of gun barrels. It is named after the Shilka River in Russia. Afghan soldiers nicknamed it the "sewing machine" due to the sound of firing guns. It is also referred to by its nickname of "Zeus", derived from the Russian acronym. History The previous Soviet self-propelled anti-aircraft gun (SPAAG), the ZSU-57-2, was armed with two 57 mm autocannons; it was aimed optically using a basic tracking and lead calculating system. The ZSU-57-2 was not particularly successful despite its very powerful autocannons; given their large caliber, it could only carry 300 rounds, was inaccurate as it lacked r ...

Grom (missile)
The Grom (meaning "thunder" in Polish) is a man-portable air-defense system produced in Poland and based on the Soviet man-portable infrared homing surface-to-air missile (SAM) 9K38 Igla. It consists of a 72 mm anti-aircraft missile set with a flight speed of 650 m/s, as well as a single-use launcher, re-usable gripstock and thermal battery coolant assembly electric unit. The full name of the system is PZR Grom, PZR standing for ''Przeciwlotniczy Zestaw Rakietowy'' (literally anti-air rocket-propelled set). It is designed to target low-flying helicopters and aeroplanes. As such, the Grom missile is used by other surface-to-air defence systems of Polish design, including ZSU-23-4MP Biała, ZUR-23-2 kg and Poprad self-propelled artillery system. It should not to be confused with versions of the Zvezda Kh-23 air-to-surface missile built under licence in Yugoslavia/Serbia as the Grom-A and Grom-B.

White
White is the lightest color and is achromatic (having no hue). It is the color of objects such as snow, chalk, and milk, and is the opposite of black. White objects fully reflect and scatter all the visible wavelengths of light. White on television and computer screens is created by a mixture of red, blue, and green light. The color white can be given with white pigments, especially titanium dioxide. In ancient Egypt and ancient Rome, priestesses wore white as a symbol of purity, and Romans wore white togas as symbols of citizenship. In the Middle Ages and Renaissance a white unicorn symbolized chastity, and a white lamb sacrifice and purity. It was the royal color of the kings of France, and of the monarchist movement that opposed the Bolsheviks during the Russian Civil War (1917–1922). Greek and Roman temples were faced with white marble, and beginning in the 18th century, with the advent of neoclassical architecture, white became the most common color of new churches ...
