Bombing Of Warsaw
The bombing of Warsaw in World War II started with the aerial bombing campaign of Warsaw by the German Luftwaffe during the siege of Warsaw in the invasion of Poland in 1939. It also included German bombing raids during the Warsaw Uprising in 1944. During the course of the war, approximately 85% of the city was destroyed due to German mass bombings, heavy artillery fire, and a planned demolition campaign. Siege of Warsaw (1939) In 1939, the Luftwaffe opened the German attack on Poland with operation Wasserkante, an air attack on Warsaw on 1 September. This attack by four bomber groups was of limited effectiveness due to low-lying cloud cover and stout Polish resistance by the PZL P.11 fighters of the Pursuit Brigade, which claimed down 16 German aircraft for the loss of 10 of their own. However, heavy losses in Polish fighter aircraft meant that by 6 September the air defense of Warsaw was in the hands of the 40 mm (24 guns), 75 mm (72 guns) anti-aircraft guns and m ...

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 ...

PZL P
PZL (''Państwowe Zakłady Lotnicze'' - State Aviation Works) was the main Polish aerospace manufacturer of the interwar period, and a brand of their aircraft. Based in Warsaw between 1928 and 1939, PZL introduced a variety of well-regarded aircraft, most notably the PZL P.11 fighter, the PZL.23 Karaś light bomber, and the PZL.37 Łoś medium bomber. In the post-war era, aerospace factories in Poland were initially run under the name WSK (Transport Equipment Manufacturing Plant), but returned to adopt PZL acronym in late 1950s. This was used as a common aircraft brand and later as a part of names of several Polish state-owned aerospace manufacturers referring to PZL traditions, and belonging to the ''Zjednoczenie Przemysłu Lotniczego i Silnikowego PZL'' - PZL Aircraft and Engine Industry Union. Among the better-known products during this period is the PZL TS-11 Iskra jet trainer and PZL-104 Wilga STOL utility aircraft. After the fall of communism in Poland in 1989, these ma ...

Siege Of Warsaw (1939)
The siege of Warsaw in 1939 was fought between the Polish Warsaw Army ( pl, Armia Warszawa) garrisoned and entrenched in Warsaw and the invading German Army.Zaloga, S.J., 2002, ''Poland 1939'', Oxford: Osprey Publishing Ltd., It began with huge aerial bombardments initiated by the Luftwaffe starting on September 1, 1939 following the Nazi invasion of Poland. Land fighting started on September 8, when the first German armored units reached the Wola district and south-western suburbs of the city. Despite German radio broadcasts claiming to have captured Warsaw, the initial enemy attack was repelled and soon afterwards Warsaw was placed under siege. The siege lasted until September 28, when the Polish garrison, commanded under General Walerian Czuma, officially capitulated. The following day approximately 140,000 Polish troops left the city and were taken as prisoners of war. On October 1 the Wehrmacht entered Warsaw, which started a period of German occupation that lasted until ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Warfare Of World War II
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in E ...

Destruction Of Warsaw
The destruction of Warsaw was Nazi Germany's substantially effected razing of the city in late 1944, after the 1944 Warsaw Uprising of the Polish resistance. The uprising infuriated German leaders, who decided to destroy the city as retaliation. The German razing of the city had long been planned. Warsaw had been selected for destruction and major reconstruction as part of the Nazis' planned Germanization of Central Europe, under the Nazi Generalplan Ost. However, by late 1944, with the war clearly lost, the Germans had abandoned their plans of colonizing the East. Thus, the destruction of Warsaw did not serve any military or colonial purpose; it was carried out solely as an act of reprisal. German forces dedicated an unprecedented effort to razing the city, destroying 80–90% of Warsaw's buildings, including the vast majority of museums, art galleries, theaters, churches, parks, and historical buildings such as castles and palaces. They deliberately demolished, burned, or st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Barrage (artillery)
In military usage, a barrage is massed sustained artillery fire (shelling) aimed at a series of points along a line. In addition to attacking any enemy in the kill zone, a barrage intends to suppress enemy movements and deny access across that line of barrage. The impact points along the line may be 20–30 yards/meters apart, with the total line length of the barrage zone anything from a few hundred to several thousand yards/meters long. Barrages can consist of multiple such lines, usually about 100 yards/meters apart, with the barrage shifting from one line to the next over time, or several lines may be targeted simultaneously. A barrage may involve a few or many artillery batteries, or even (rarely) a single gun. Typically each gun in a barrage, using indirect fire, will fire continuously at a steady rate at its assigned point for an assigned time before moving onto the next target, following the barrage's detailed timetable. Barrages typically use high-explosive shells, bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Close-quarters Combat
Close-quarters combat (CQC) or close-quarters battle (CQB) is a tactical situation that involves a physical fight with firearms involved between multiple combatants at short range. It can occur between military units, police/corrections officers and criminal elements, and in other similar situations. In warfare, it usually consists of units or teams of varying size engaging the target or attacking personnel with personal weapons within a distance of up to 100 meters (110 yards), from proximity hand-to-hand combat to close-quarter target negotiation with usually automatic weapons. In the typical close combat scenario, the attackers try a very fast, violent takeover of a vehicle or structure controlled by the defenders, who usually have no easy method to withdraw. Because attacking and defending personnel, hostages/civilians, and friendly personnel can be closely intermingled, close-quarters combat demands a rapid assault and a precise implementation of lethal force. The operators ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Home Army
The Home Army ( pl, Armia Krajowa, abbreviated AK; ) was the dominant resistance movement in German-occupied Poland during World War II. The Home Army was formed in February 1942 from the earlier Związek Walki Zbrojnej (Armed Resistance) established in the aftermath of the German and Soviet invasions in September 1939. Over the next two years, the Home Army absorbed most of the other Polish partisans and underground forces. Its allegiance was to the Polish government-in-exile in London, and it constituted the armed wing of what came to be known as the Polish Underground State. Estimates of the Home Army's 1944 strength range between 200,000 and 600,000. The latter number made the Home Army not only Poland's largest underground resistance movement but, along with Soviet and Yugoslav partisans, one of Europe's largest World War II underground movements. The Home Army sabotaged German transports bound for the Eastern Front in the Soviet Union, destroying German supplies and ty ...

Airstrike
An airstrike, air strike or air raid is an offensive operation carried out by aircraft. Air strikes are delivered from aircraft such as blimps, balloons, fighters, heavy bombers, ground attack aircraft, attack helicopters and drones. The official definition includes all sorts of targets, including enemy air targets, but in popular usage the term is usually narrowed to a tactical (small-scale) attack on a ground or naval objective as opposed to a larger, more general attack such as carpet bombing. Weapons used in an airstrike can range from direct-fire aircraft-mounted cannons and machine guns, rockets and air-to-surface missiles, to various types of aerial bombs, glide bombs, cruise missiles, ballistic missiles, and even directed-energy weapons such as laser weapons. In close air support, air strikes are usually controlled by trained observers on the ground for coordination with ground troops and intelligence in a manner derived from artillery tactics.

Close Air Support
In military tactics, close air support (CAS) is defined as air action such as air strikes by fixed or rotary-winged aircraft against hostile targets near friendly forces and require detailed integration of each air mission with fire and movement of these forces and attacks with aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.''Close Air Support''. United States Department of Defense, 2014. The requirement for detailed integration because of proximity, fires or movement is the determining factor. CAS may need to be conducted during shaping operations with Special Operations Forces (SOF) if the mission requires detailed integration with the fire and movement of those forces. A closely related subset of air interdiction (AI), battlefield air interdiction, denotes interdiction against units with near-term effects on friendly units, but which does not require integration with friendly troop movements. The ter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Supremacy
Aerial supremacy (also air superiority) is the degree to which a side in a conflict holds control of air power over opposing forces. There are levels of control of the air in aerial warfare. Control of the air is the aerial equivalent of command of the sea. Air power has increasingly become a powerful element of military campaigns; military planners view having an environment of at least air superiority as a necessity. Air supremacy allows increased bombing efforts, tactical air support for ground forces, paratroop assaults, airdrops and simple cargo plane transfers, which can move ground forces and supplies. Air power is a function of the degree of air superiority and numbers or types of aircraft, but it represents a situation that defies black-and-white characterization. The degree of a force's air control is a zero-sum game with its opponent's; increasing control by one corresponds to decreasing control by the other. Air forces unable to contest for air superiority or a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Junkers Ju 52
The Junkers Ju 52/3m (nicknamed ''Tante Ju'' ("Aunt Ju") and ''Iron Annie'') is a transport aircraft that was designed and manufactured by German aviation company Junkers. Development of the Ju 52 commenced during 1930, headed by German Aerospace engineering, aeronautical engineer Ernst Zindel. The aircraft's design incorporated a wikt:corrugated, corrugated duralumin metal skin as a strengthening measure, which was very unusual at the time. The Ju 52's maiden flight was performed on 13 October 1930. It was initially designed with a single engine, however, it was produced in quantity as a trimotor. The primary early production model, the ''Ju 52/3m'', was principally operated as a 17-seat airliner or utility transport aircraft by various civil operators during the 1930s. Following the rise of Nazi Germany, thousands of Ju 52s were procured as a staple military transport of the nation. The ''Ju 52/3mg7e'' was the principal production model. The Ju 52 was in production between 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
