Pathfinder (USAAF)
The 482d Operations Group is a United States Air Force Reserve unit assigned to the 482d Fighter Wing. It is stationed at Homestead Air Reserve Base, Florida. During World War II, the group was activated in England as the 482d Bombardment Group (Pathfinder), the only Eighth Air Force radar-equipped pathfinder heavy bomber group. Its Boeing B-17 Flying Fortress and Consolidated B-24 Liberator aircraft were equipped with first generation radars to guide other bombardment groups to targets obscured by cloud cover over Occupied Europe and Nazi Germany, earning a Distinguished Unit Citation. In 1944, it was removed from combat to focus on training pathfinder aircrews and develop tactics, although its developmental work occasionally required it to fly combat missions. After V-E Day, the group returned to the United States and was inactivated. The group became a reserve organization, serving as a bombardment unit from 1947-1949 and briefly as an airlift unit in 1952. It became a f ...

Air Force Reserve Command
The Air Force Reserve Command (AFRC) is a major command (MAJCOM) of the United States Air Force, with its headquarters at Robins Air Force Base, Georgia. It is the federal Air Reserve Component (ARC) of the U.S. Air Force, consisting of commissioned officers and enlisted airmen. AFRC also plays an integral role in the day-to-day Air Force mission and is not strictly a force held in reserve for possible war or contingency operations. AFRC also supports the United States Space Force through the 310th Space Wing, pending the creation of a space reserve component. Overview The federal reserve component of the United States Air Force, AFRC has approximately 450 aircraft assigned for which it has sole control, as well as access to several hundred additional active duty USAF aircraft via AFRC "Associate" wings that are collocated with active duty Air Force wings, sharing access to those same active duty Air Force aircraft. The inventory, both AFRC-controlled and active duty Regular A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V-E Day
Victory in Europe Day is the day celebrating the formal acceptance by the Allies of World War II of Germany's unconditional surrender of its armed forces on Tuesday, 8 May 1945, marking the official end of World War II in Europe in the Eastern Front, with the last shots fired on the 11th. Russia and some former Soviet countries celebrate on 9 May. Several countries observe public holidays on the day each year, also called Victory Over Fascism Day, Liberation Day or Victory Day. In the UK it is often abbreviated to VE Day, or V-E Day in the US, a term which existed as early as September 1944, in anticipation of victory. The end of all combat actions was specified as 23:01 Central European Time, which was already 9 May in eastern Europe, and thus several former Soviet bloc countries including Russia and Belarus, as well as some former Yugoslav countries like Serbia, celebrate Victory Day on 9 May.

Wing (military Aviation Unit)
In military aviation, a wing is a unit of command. In most military aviation services, a wing is a relatively large formation of planes. In Commonwealth countries a wing usually comprises three squadrons, with several wings forming a group (around 10 squadrons). Each squadron will contain around 20 planes. Commonwealth usage Origins On its establishment in 1912, the British Royal Flying Corps (RFC) was intended to be an inter-service, combined force of the British Army and Royal Navy. Given the rivalry that existed between the army and navy, new terminology was used, in order to avoid marking the corps out as having an army or navy ethos. While the term "wing" had been used in the cavalry, its more general use predominated. Accordingly, the word "wing", with its allusion of flight, was chosen as the term of subdivision and the corps was split into a "Military Wing" (i.e. an army wing) and a "Naval Wing". Each wing consisted of a number of squadrons (the term "squadro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Group (military Aviation Unit)
A group is a military unit or a military formation that is most often associated with military aviation. Air and aviation groups The terms group and wing differ significantly from one country to another, as well as between different branches of a national defence force. Air groups vary considerably in size and status, but generally take two forms: * A unit of two to four squadrons, commanded by a lieutenant colonel, colonel, commander, naval captain or an equivalent rank. The United States Air Force (USAF), ''groupes'' of the French ''Armée de l'air'', ''gruppen'' of the German ''Luftwaffe'', United States Marine Corps Aviation, British Fleet Air Arm and some other naval air services usually follow this pattern. * A larger formation, often comprising more than 10 squadrons, commanded by a major general, brigadier general, commodore, rear admiral, air commodore or air vice-marshal. The air forces of many Commonwealth countries, such as the British Royal Air Force (RAF), f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gee (navigation)
Gee, sometimes written GEE, was a radio navigation system used by the Royal Air Force during World War II. It measured the time delay between two radio signals to produce a fix, with accuracy on the order of a few hundred metres at ranges up to about . It was the first hyperbolic navigation system to be used operationally, entering service with RAF Bomber Command in 1942. Gee was devised by Robert Dippy as a short-range blind landing system to improve safety during night operations. During development by the Telecommunications Research Establishment (TRE) at Swanage, the range was found to be far better than expected. It then developed into a long-range, general navigation system. For large, fixed targets, such as the cities that were attacked at night, Gee offered enough accuracy to be used as an aiming reference without the need to use a bombsight or other external references. Jamming reduced its usefulness as a bombing aid, but it remained in use as a navigational aid in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
329th Bombardment Squadron
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

H2X Radar
H2X, officially known as the AN/APS-15, was an American ground scanning radar system used for blind bombing during World War II. It was a development of the British H2S radar, the first ground mapping radar to be used in combat. It was also known as the "Mickey set" and "BTO" for "bombing through the overcast" radar. H2X differed from the original H2S primarily in its X band 10 GHz operating frequency rather than H2S' S band 3 GHz emissions. This gave H2X higher resolution than H2S, allowing it to provide usable images over large cities which appeared as a single blob on the H2S display. The Royal Air Force (RAF) initially considered using H2X as well, but would instead develop their own X band system, the H2S Mk. III. The RAF system entered service in late 1943, before the first use of H2X in early 1944. The desire for even higher resolution, enough to image individual docks and bridges, led to a number of variations on the H2X system, as well as the more advanced AN/ ...

H2S Radar
H2S was the first airborne, ground scanning radar system. It was developed for the Royal Air Force's Bomber Command during World War II to identify targets on the ground for night and all-weather bombing. This allowed attacks outside the range of the various radio navigation aids like Gee or Oboe, which were limited to about . It was also widely used as a general navigation system, allowing landmarks to be identified at long range. In March 1941, experiments with an early airborne interception radar based on the 9.1 cm wavelength, (3 GHz) cavity magnetron revealed that different objects have very different radar signatures; water, open land and built-up areas of cities and towns all produced distinct returns. In January 1942, a new team was set up to combine the magnetron with a new scanning antenna and plan-position indicator display. The prototype's first use in April confirmed that a map of the area below the aircraft could be produced using radar. The first systems ...

Royal Air Force
The Royal Air Force (RAF) is the United Kingdom's air and space force. It was formed towards the end of the First World War on 1 April 1918, becoming the first independent air force in the world, by regrouping the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). Following the Allied victory over the Central Powers in 1918, the RAF emerged as the largest air force in the world at the time. Since its formation, the RAF has taken a significant role in British military history. In particular, it played a large part in the Second World War where it fought its most famous campaign, the Battle of Britain. The RAF's mission is to support the objectives of the British Ministry of Defence (MOD), which are to "provide the capabilities needed to ensure the security and defence of the United Kingdom and overseas territories, including against terrorism; to support the Government's foreign policy objectives particularly in promoting international peace and security".

Norden Bombsight
The Norden Mk. XV, known as the Norden M series in U.S. Army service, is a bombsight that was used by the United States Army Air Forces (USAAF) and the United States Navy during World War II, and the United States Air Force in the Korean and the Vietnam Wars. It was an early tachometric design that directly measured the aircraft's ground speed and direction, which older bombsights could only estimate with lengthy manual procedures. The Norden further improved on older designs by using an analog computer that continuously recalculated the bomb's impact point based on changing flight conditions, and an autopilot that reacted quickly and accurately to changes in the wind or other effects. Together, these features promised unprecedented accuracy for daytime bombing from high altitudes. During prewar testing the Norden demonstrated a circular error probable (CEP) of , an astonishing performance for that period. This precision would enable direct attacks on ships, factories, and oth ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
