506th Air Refueling Squadron
The 506th Air Refueling Squadron is an inactive United States Air Force unit. It was last assigned to the 42d Air Division at Bergstrom Air Force Base, Texas where it was inactivated on 1 July 1957 and its personnel and equipment transferred to the 92d Air Refueling Squadron. The Squadron was first activated as the 406th Fighter Squadron in 1943, one of the original squadrons of the 371st Fighter Group. The squadron saw combat in the European theater of World War II before being inactivated in 1945, earning a Distinguished Unit Citation for its attacks in March 1945 that contributed to the defeat of Axis forces in southern Germany. The 506th Air Refueling Squadron was established in 1953 by Strategic Air Command (SAC) at Dow Air Force Base, Maine and equipped with rigid flying boom KB-29P Superfortress tankers. The squadron mission was to provide in-flight refueling for its parent wing and other USAF units. It moved to Bergstrom in 1955 and was inactivated there when SAC tran ...

Republic P-47D Thunderbolt
The P-47 Thunderbolt was a World War II fighter aircraft built by Republic Aviation from 1941 to 1945. Early designs XP-47 (AP-10) In response to a USAAC requirement for a new fighter aircraft, Republic Aviation engineer Alexander Kartveli proposed the AP-10 lightweight high-altitude interceptor on August 1, 1939. As originally proposed, the AP-10 was to have been powered by a 1,150 hp Allison V-1710-39 12-cylinder inline engine and have an armament consisting of two nose-mounted .50 in (12.7 mm) M2 Browning machine guns. Maximum speed was estimated to be 415 mph, while gross weight was to be 4,900 lb. The USAAC was impressed by the AP-10 proposal, but expressed concerns that it would be underarmed. Kartveli revised the AP-10 by slightly increasing its size and mounting two .30 in (7.62 mm) M1919 Browning machine guns in each wing, raising the gross weight to 6,570 lb. Satisfied, the USAAC ordered a single prototype under the designation XP-47, in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an a ..., army aviation, or naval aviation is a Military unit, unit comprising a number of military aircraft and their aircrews, usually of the same type, typically with 12 to 24 aircraft, sometimes divided into three or four flight (military unit), flights, depending on aircraft type and air force. Land-based squadrons equipped with heavier type aircraft such as long-range bombers, cargo aircraft, or air refueling tankers have around 12 aircraft as a typical authorization, while most land-based fighter equipped units have an authorized number of 18 to 24 aircraft. In naval aviation, sea-based and land-based squadrons will typically have smaller numbers of aircraft, ranging from as low as four for early warning t ...

Battle Of The Bulge
The Battle of the Bulge, also known as the Ardennes Offensive, was the last major German offensive (military), offensive military campaign, campaign on the Western Front (World War II), Western Front during World War II. The battle lasted from 16 December 1944 to 28 January 1945, towards the end of the war in Europe. It was launched through the densely forested Ardennes region between Belgium and Luxembourg. The primary military objectives were to deny further use of the Belgian port of Antwerp to the Allies and to split the Allied lines, which potentially could have allowed the Germans to encirclement, encircle and destroy the four Allied forces. Nazi dictator Adolf Hitler, who since December 1941 had assumed direct command of the German army, believed that achieving these objectives would compel the Western Allies to accept a peace treaty in the Axis powers' favor. By this time, it was palpable to virtually the entire German leadership including Hitler himself that they had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Marshalling Yard
A classification yard (American and Canadian English (Canadian National Railway use)), marshalling yard (British, Hong Kong, Indian, Australian, and Canadian English (Canadian Pacific Railway use)) or shunting yard (Central Europe) is a railway yard found at some freight train stations, used to separate railway cars onto one of several tracks. First the cars are taken to a track, sometimes called a ''lead'' or a ''drill''. From there the cars are sent through a series of switches called a ''ladder'' onto the classification tracks. Larger yards tend to put the lead on an artificially built hill called a ''hump'' to use the force of gravity to propel the cars through the ladder. Freight trains that consist of isolated cars must be made into trains and divided according to their destinations. Thus the cars must be shunted several times along their route in contrast to a unit train, which carries, for example, cars from the plant to a port, or coal from a mine to the power plant. ...

Air Interdiction
Air interdiction (AI), also known as deep air support (DAS), is the use of preventive tactical bombing and strafing by combat aircraft against enemy targets that are not an immediate threat, to delay, disrupt or hinder later enemy engagement of friendly forces. It is a core capability of virtually all military air forces, and has been conducted in conflicts since World War I. A distinction is often made between tactical and strategic air interdiction, depending on the objectives of the operation. Typical objectives in tactical interdiction are meant to affect events rapidly and locally, for example through direct destruction of forces or supplies en route to the active battle area. By contrast, strategic objectives are often broader and more long-term, with fewer direct attacks on enemy fighting capabilities, instead focusing on infrastructure, logistics and other supportive assets. The term deep air support relates to close air support and denotes the difference between their re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-Day
The Normandy landings were the landing operations and associated airborne operations on Tuesday, 6 June 1944 of the Allied invasion of Normandy in Operation Overlord during World War II. Codenamed Operation Neptune and often referred to as D-Day, it was the largest seaborne invasion in history. The operation began the liberation of France (and later 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 D-Day was far from 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 invasion planners had requirements for the phase of the moon, the tides, and the time of day that meant only a few days each month were d ...

Escort Fighter
The escort fighter was a concept for a fighter aircraft designed to escort bombers to and from their targets. An escort fighter needed range long enough to reach the target, loiter over it for the duration of the raid to defend the bombers, and return. A number of twin-engined heavy fighters with high fuel capacity were designed for escort duties prior to the outbreak of World War II. Such heavy fighters largely failed in their intended escort role during the war, as they were commonly outmaneuvered by more agile single-engined fighters. As the war progressed, longer-range fighter designs and the use of drop tanks allowed single-engined fighters to perform escort duties. In the post-war era the introduction of jet engines and their inherent short range made escort fighters very difficult to build. The related concept of a penetration fighter emerged briefly in the 1950s and again in the 1960s, but did not result in any production aircraft. The escort role has been diminished as ...

Dive Bomber
A dive bomber is a bomber aircraft that dives directly at its targets in order to provide greater accuracy for the bomb it drops. Diving towards the target simplifies the bomb's trajectory and allows the pilot to keep visual contact throughout the bomb run. This allows attacks on point targets and ships, which were difficult to attack with conventional level bombers, even ''en masse''. After World War II, the rise of precision-guided munitions and improved anti-aircraft defences—both fixed gunnery positions and fighter interception—led to a fundamental change in dive bombing. New weapons, such as rockets, allowed for better accuracy from smaller dive angles and from greater distances. They could be fitted to almost any aircraft, including fighters, improving their effectiveness without the inherent vulnerabilities of dive bombers, which needed air superiority to operate effectively. Method A dive bomber dives at a steep angle, normally between 45 and 60 degrees or ev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Operation Overlord
Operation Overlord was the codename for the Battle of Normandy, the Allies of World War II, Allied operation that launched the successful invasion of German-occupied Western Front (World War II), Western Europe during World War II. The operation was launched on 6 June 1944 (D-Day) with the Normandy landings. A 1,200-plane Airborne forces, airborne assault preceded an amphibious warfare, amphibious assault involving more than 5,000 vessels. Nearly 160,000 troops crossed the English Channel on 6 June, and more than two million Allied troops were in France by the end of August. The decision to undertake a cross-channel invasion in 1944 was taken at the Washington Conference (1943), Trident Conference in Washington, D.C., Washington in May 1943. General Dwight D. Eisenhower was appointed commander of Supreme Headquarters Allied Expeditionary Force, and General Bernard Montgomery was named commander of the 21st Army Group, which comprised all the land forces involved in the invasio ...

RAF Bisterne
Royal Air Force Bisterne or more simply RAF Bisterne is a former Royal Air Force Advanced Landing Ground in Hampshire, England. The airfield is located in the hamlet of Bisterne approximately south of Ringwood; about southwest of London. Opened in March 1944, Bisterne was a prototype for the type of temporary Advanced Landing Ground type airfield that would be built in France after D-Day, when the need advanced landing fields would become urgent as the Allied forces moved east across France and Germany. It was used by the United States Army Air Force as a fighter airfield. It was closed late in the summer of 1944. Today the airfield is a mixture of agricultural fields with no recognizable remains. History Bisterne was used by the No. 2774 Squadron RAF Regiment. Bisterne was known as USAAF Station AAF-415 for security reasons by the USAAF during the war, and by which it was referred to instead of location. Its USAAF Station Code was "BS".
