KC-97 Stratofreighter
The Boeing KC-97 Stratofreighter is a four-engined, piston-powered United States strategic tanker aircraft based on the Boeing C-97 Stratofreighter. It replaced the KB-29 and was succeeded by the Boeing KC-135 Stratotanker. Design and development The KC-97 Stratofreighter was an aerial refueling tanker variant of the C-97 Stratofreighter (which was itself based on the Boeing B-29 Superfortress), greatly modified with all the necessary tanks, plumbing, and a flying boom first developed for the KB-29 bomber. The cavernous upper deck was capable of accommodating oversize cargo accessed through a very large right-side door. In addition, transferable jet fuel was contained in tanks on the lower deck (G-L models). Both decks were heated and pressurized for high altitude operations. The boom operator lay prone, viewing operations through a window at the bottom of the tail, a configuration later used on the KC-135. ''Note: Occasionally the KC-97 has been referred to as "Stratotanker". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
409bg-a26
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is a square number, the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. Evolution of the Hindu-Arabic digit Brahmic numerals represented 1, 2, and 3 with as many lines. 4 was simplified by joining its four lines into a cross that looks like the modern plus sign. The Shunga would add a horizontal line on top of the digit, and the Kshatrapa and Pallava evolved the digit to a point where the speed of writing was a secondary concern. The Arabs' 4 still had the early concept of the cross, but for the sake of efficiency, was made in one stroke by connecting the "western" end to the "northern" end; the "eastern" end was finished off with a curve. The Europeans dropped the finishing curve and gradually made the digit less cursive, ending up with a digit very close to the original Brahmin cross. While the shape of the character for ...

Anti-aircraft Warfare
Anti-aircraft warfare (AAW) is the counter to aerial warfare and includes "all measures designed to nullify or reduce the effectiveness of hostile air action".AAP-6 It encompasses surface-based, subsurface (Submarine#Armament, submarine-launched), and air-based weapon systems, in addition to associated sensor systems, command and control arrangements, and passive measures (e.g. barrage balloons). It may be used to protect naval, army, ground, and air forces in any location. However, for most countries, the main effort has tended to be homeland defense. Missile defense, Missile defense is an extension of air defence, as are initiatives to adapt air defence to the task of intercepting any projectile in flight. Most modern anti-aircraft (AA) weapons systems are optimized for short-, medium-, or long-range air defence, although some systems may incorporate multiple weapons (such as both autocannons and surface-to-air missiles). 'Layered air defence' usually refers to multiple 't ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Codenamed Operation Neptune and often referred to as D-Day (after the military term), it is the largest seaborne invasion in history. The operation began the liberation of France, and the rest of Western Europe, and laid the foundations of the Allied victory on the Western Front. Planning for the operation began in 1943. In the months leading up to the invasion, the Allies conducted a substantial military deception, codenamed Operation Bodyguard, to mislead the Germans as to the date and location of the main Allied landings. The weather on the day selected for D-Day was not ideal, and the operation had to be delayed 24 hours; a further postponement would have meant a delay of at least two weeks, as the planners had requirements for the phase of the moon, the tides, and time of day, that ...

Airfield
An aerodrome, airfield, or airstrip is a location from which aircraft flight operations take place, regardless of whether they involve air cargo, passengers, or neither, and regardless of whether it is for public or private use. Aerodromes include small general aviation airfields, large commercial airports, and military air bases. The term ''airport'' may imply a certain stature (having satisfied certain certification criteria or regulatory requirements) that not all aerodromes may have achieved. That means that all airports are aerodromes, but not all aerodromes are airports. Usage of the term "aerodrome" (or "airfield") remains more common in Commonwealth English, and is conversely almost unknown in American English, where the term "airport" is applied almost exclusively. A water aerodrome is an area of open water used regularly by seaplanes, floatplanes or amphibious aircraft for landing and taking off. In formal terminology, as defined by the International Civil ...

V-2 Rocket
The V2 (), with the technical name ''Aggregat (rocket family), Aggregat-4'' (A4), was the world's first long-range missile guidance, guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a "V-weapons, vengeance weapon" and assigned to attack Allies of World War II, Allied cities as retaliation for the Strategic bombing during World War II#The British later in the war, Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the . Beginning in September 1944, more than 3,000 were launched by the Wehrmacht against Allied targets, first London and ...

V-1 Flying Bomb
The V-1 flying bomb ( "Vengeance Weapon 1") was an early cruise missile. Its official Reich Aviation Ministry () name was Fieseler Fi 103 and its suggestive name was (hellhound). It was also known to the Allies as the buzz bomb or doodlebug and (maybug). The V-1 was the first of the (V-weapons) deployed for the terror bombing of London. It was developed at Peenemünde Army Research Center in 1939 by the at the beginning of the Second World War, and during initial development was known by the codename "Cherry Stone". Due to its limited range, the thousands of V-1 missiles launched into England were fired from V-1 flying bomb facilities, launch sites along the French (Pas-de-Calais) and Dutch coasts or by modified Heinkel He 111 aircraft. The Wehrmacht first launched the V-1s against London on 13 June 1944, one week after (and prompted by) Operation Overlord, the Allied landings in France.

Coastal Defence And Fortification
300px, Cartagena_de_Indias.html" ;"title="Castillo San Felipe de Barajas in Cartagena de Indias">Castillo San Felipe de Barajas in Cartagena de Indias, Colombia Coastal defence (or defense) and coastal fortification are measures taken to provide protection against military attack at or near a coastline (or other shoreline), for example, fortifications and coastal artillery. Because an invading enemy normally requires a port or harbour to sustain operations, such defences are usually concentrated around such facilities, or places where such facilities could be constructed. Coastal artillery fortifications generally followed the development of land fortifications, usually incorporating land defences; sometimes separate land defence forts were built to protect coastal forts. Through the middle 19th century, coastal forts could be bastion forts, star forts, polygonal forts, or sea forts, the first three types often with detached gun batteries called "water batteries".

Occupied France
The Military Administration in France (; ) was an interim occupation authority established by Nazi Germany during World War II to administer the occupied zone in areas of northern and western France. This so-called ' was established in June 1940, and renamed ' ("north zone") in November 1942, when the previously unoccupied zone in the south known as ' ("free zone") was also occupied and renamed ' ("south zone"). Its role in France was partly governed by the conditions set by the Armistice of 22 June 1940 after the success of the leading to the Fall of France; at the time both French and Germans thought the occupation would be temporary and last only until Britain came to terms, which was believed to be imminent. For instance, France agreed that its soldiers would remain prisoners of war until the cessation of all hostilities. The "French State" (') replaced the French Third Republic that had dissolved in defeat. Though nominally extending its sovereignty over the whole cou ...
