Zoo Tower
The Zoo flak tower (German: ''Flakturm Grosser Tiergarten, Tiergarten'', ''Tiergarten Flak Tower'' or commonly referred to as the "Zoo Tower") was a fortified flak tower that existed in Berlin from 1941 to 1947. It was one of several flak towers that protected Berlin from Bombing of Berlin during World War II, Allied bomber raids. Its primary role was as a gun platform to protect the government building district of Berlin; in addition, the ''Hochbunker'' (blockhouse) was designed to be used as a civilian air-raid shelter. It also contained a hospital and a radio transmitter for use by the German leadership and provided secure storage facilities for art treasures. During the Battle of Berlin, it acted as a citadel and by depressing its large anti-aircraft artillery, its garrison was able to provide support for ground operations against the Soviet Red Army. Development The Berlin flak towers (''Flaktürme'', singular ''Flakturm'') were originally built as a response to an attack ...

Radar
Radar is a system that uses radio waves to determine the distance ('' ranging''), direction ( azimuth and elevation angles), and radial velocity of objects relative to the site. It is a radiodetermination method used to detect and track aircraft, ships, spacecraft, guided missiles, motor vehicles, map weather formations, and terrain. The term ''RADAR'' was coined in 1940 by the United States Navy as an acronym for "radio detection and ranging". The term ''radar'' has since entered English and other languages as an anacronym, a common noun, losing all capitalization. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwave domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
USAAF
The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and ''de facto'' aerial warfare service branch of the United States during and immediately after World War II (1941–1947). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six United States Armed Forces, armed forces of the United States. The AAF was a component of the United States Army, which on 2 March 1942 was divided functionally by executive order into three autonomous forces: the Army Ground Forces, the United States Army Services of Supply (which in 1943 became the Army Service Forces), and the Army Air Forces. Each of these forces had a commanding general who reported directly to the Chief of Staff of the United States Army, Army Chief of Staff. The AAF administered all parts of military aviation formerly distributed am ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Luftwaffe
The Luftwaffe () was the aerial warfare, aerial-warfare branch of the before and during World War II. German Empire, Germany's military air arms during World War I, the of the Imperial German Army, Imperial Army and the of the Imperial German Navy, Imperial Navy, had been disbanded in May 1920 in accordance with the terms of the 1919 Treaty of Versailles, which banned Germany from having any air force. During the interwar period, German pilots were trained secretly in violation of the treaty at Lipetsk (air base), Lipetsk Air Base in the Soviet Union. With the rise of the Nazi Party and the repudiation of the Versailles Treaty, the Luftwaffe's existence was publicly acknowledged and officially established on 26 February 1935, just over two weeks before open defiance of the Versailles Treaty through German rearmament and conscription would be announced on 16 March. The Condor Legion, a Luftwaffe detachment sent to aid Nationalist faction (Spanish Civil War), Nationalist for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bundesarchiv Bild 183-G1230-0502-004, Berlin, Zoo-Flakturm, Flak-Vierling
The German Federal Archives or Bundesarchiv (BArch) (, lit. "Federal Archive") are the national archives of Germany. They were established at the current location in Koblenz in 1952. They are subordinated to the Federal Commissioner for Culture and the Media ( Claudia Roth since 2021) under the German Chancellery, and before 1998, to the Federal Ministry of the Interior. On 6 December 2008, the Archives donated 100,000 photos to the public, by making them accessible via Wikimedia Commons. History The federal archive for institutions and authorities in Germany, the first precursor to the present-day Federal Archives, was established in Potsdam, Brandenburg in 1919, a later date than in other European countries. This national archive documented German government dating from the founding of the North German Confederation in 1867. It also included material from the older German Confederation and the Imperial Chamber Court. The oldest documents in this collection dated back to the ...

Military
A military, also known collectively as armed forces, is a heavily armed, highly organized force primarily intended for warfare. Militaries are typically authorized and maintained by a sovereign state, with their members identifiable by a distinct military uniform. They may consist of one or more military branches such as an army, navy, air force, space force, marines, or coast guard. The main task of a military is usually defined as defence of their state and its interests against external armed threats. In broad usage, the terms "armed forces" and "military" are often synonymous, although in technical usage a distinction is sometimes made in which a country's armed forces may include other paramilitary forces such as armed police. Beyond warfare, the military may be employed in additional sanctioned and non-sanctioned functions within the state, including internal security threats, crowd control, promotion of political agendas, emergency services and reconstruct ...

Combatants
Combatant is the legal status of a person entitled to directly participate in hostilities during an armed conflict, and may be intentionally targeted by an adverse party for their participation in the armed conflict. Combatants are not afforded immunity from being directly targeted in situations of armed conflict and can be attacked regardless of the specific circumstances simply due to their status, so as to deprive their side of their support. In an interstate conflict, the definition of "combatant" is found in Article 43 (2) of Additional Protocol I to the 1949 Geneva Conventions: "Members of the armed forces of a Party to a conflict (other than medical personnel and chaplains covered by Article 33 of the Third enevaConvention) are combatants, that is to say, they have the right to participate directly in hostilities." Combatants when captured by an opposing party are automatically granted the status of protected persons, whether as prisoners of war or unlawful combatants. ...

Barrel
A barrel or cask is a hollow cylindrical container with a bulging center, longer than it is wide. They are traditionally made of wooden stave (wood), staves and bound by wooden or metal hoops. The word vat is often used for large containers for liquids, usually alcoholic beverages; a small barrel or cask is known as a keg. Barrels have a variety of uses, including storage of liquids such as water, oil, and alcohol. They are also employed to hold maturing beverages such as wine, Cognac (brandy), cognac, Armagnac (drink), armagnac, sherry, port wine, port, whiskey, beer, arrack, and sake. Other commodities once stored in wooden casks include gunpowder, Salt-cured meat, meat, fish, paint, honey, nails, and tallow. Modern wooden barrels for wine-making are made of English oak (''Quercus robur''), white Oak (wine), oak (''Quercus petraea''), American white oak (''Quercus alba''), more exotic is mizunara oak (''Quercus crispula''), and recently Oregon oak (''Quercus garryana'') ...

Altitudes
Altitude is a distance measurement, usually in the vertical or "up" direction, between a reference datum and a point or object. The exact definition and reference datum varies according to the context (e.g., aviation, geometry, geographical survey, sport, or atmospheric pressure). Although the term ''altitude'' is commonly used to mean the height above sea level of a location, in geography the term elevation is often preferred for this usage. In aviation, altitude is typically measured relative to mean sea level or above ground level to ensure safe navigation and flight operations. In geometry and geographical surveys, altitude helps create accurate topographic maps and understand the terrain's elevation. For high-altitude trekking and sports, knowing and adapting to altitude is vital for performance and safety. Higher altitudes mean reduced oxygen levels, which can lead to altitude sickness if proper acclimatization measures are not taken. Vertical distance measurements in ...

Bombers
A bomber is a military combat aircraft that utilizes air-to-ground weaponry to drop bombs, launch torpedoes, or deploy air-launched cruise missiles. There are two major classifications of bomber: strategic and tactical. Strategic bombing is done by heavy bombers primarily designed for long-range bombing missions against strategic targets to diminish the enemy's ability to wage war by limiting access to resources through crippling infrastructure, reducing industrial output, or inflicting massive civilian casualties to an extent deemed to force surrender. Tactical bombing is aimed at countering enemy military activity and in supporting offensive operations, and is typically assigned to smaller aircraft operating at shorter ranges, typically near the troops on the ground or against enemy shipping. Bombs were first dropped from an aircraft during the Italo-Turkish War, with the first major deployments coming in the First World War and Second World War by all major airforces, da ...

Ferro-concrete
Reinforced concrete, also called ferroconcrete or ferro-concrete, is a composite material in which concrete's relatively low ultimate tensile strength, tensile strength and ductility are compensated for by the inclusion of reinforcement having higher tensile strength or ductility. The reinforcement is usually, though not necessarily, steel reinforcing bars (known as rebar) and is usually embedded passively in the concrete before the concrete sets. However, Prestressed concrete#Post-tensioned concrete, post-tensioning is also employed as a technique to reinforce the concrete. In terms of volume used annually, it is one of the most common engineering materials. In corrosion engineering terms, when designed correctly, the alkalinity of the concrete protects the steel rebar from corrosion. Description Reinforcing schemes are generally designed to resist Tension (physics), tensile Stress (mechanics), stresses in particular regions of the concrete that might cause unacceptable frac ...

Hitler Youth
The Hitler Youth ( , often abbreviated as HJ, ) was the youth wing of the German Nazi Party. Its origins date back to 1922 and it received the name ("Hitler Youth, League of German Worker Youth") in July 1926. From 1936 until 1945, it was the sole official boys' youth organisation in Germany (although the League of German Girls was a wing of it) and it was partially a paramilitary organisation. It was composed of the Hitler Youth proper for male youths aged 14 to 18, and the Deutsches Jungvolk, German Youngsters in the Hitler Youth ( or "DJ", also "DJV") for younger boys aged 10 to 14. With the German Instrument of Surrender, surrender of Nazi Germany in 1945, the organisation ''de facto'' ceased to exist. On 10 October 1945, the Hitler Youth and its subordinate units were outlawed by the Allied Control Council along with other Nazi Party organisations. Under Strafgesetzbuch section 86a, Section 86 of the Strafgesetzbuch, Criminal Code of the Germany, Federal Republic of Germ ...
