Haywood S. Hansell
Haywood Shepherd Hansell Jr. (September 28, 1903 – November 14, 1988) was a general officer in the United States Army Air Forces (USAAF) during World War II, and later the United States Air Force. He became an advocate of the doctrine of strategic bombardment, and was one of the chief architects of the concept of daylight precision bombing that governed the use of airpower by the USAAF in the war. Hansell played a key and largely unsung role in the strategic planning of air operations by the United States. This included drafting both the strategic air war plans (AWPD-1 and AWPD-42) and the plan for the Combined Bomber Offensive in Europe; obtaining a base of operations for the B-29 Superfortress in the Mariana Islands; and devising the command structure of the Twentieth Air Force, the first global strategic air force and forerunner of the Strategic Air Command. He made precision air attack, as both the most humane and effective means of achieving military success, a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fort Monroe, Virginia
Fort Monroe, managed by partnership between the Fort Monroe Authority for the Commonwealth of Virginia, the National Park Service as the Fort Monroe National Monument, and the City of Hampton, is a former military installation in Hampton, Virginia, at Old Point Comfort, the southern tip of the Virginia Peninsula, United States. Along with Fort Wool, Fort Monroe originally guarded the navigation channel between the Chesapeake Bay and Hampton Roads—the natural roadstead at the confluence of the Elizabeth, the Nansemond and the James rivers. Union General George B. McClellan landed his forces at the fort during Peninsula campaign of 1862 during the American Civil War. Until disarmament in 1946, the areas protected by the fort were the entire Chesapeake Bay and Potomac River regions, including the water approaches to the cities of Washington, D.C. and Baltimore, Maryland, along with important shipyards and naval bases in the Hampton Roads area. Surrounded by a moat, the six-si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Bombing
Strategic bombing is a military strategy used in total war with the goal of defeating the enemy by destroying its morale, its economic ability to produce and transport materiel to the theatres of military operations, or both. It is a systematically organized and executed attack from the air which can utilize strategic bombers, long- or medium-range missiles, or nuclear-armed fighter-bomber aircraft to attack targets deemed vital to the enemy's war-making capability. The term terror bombing is used to describe the strategic bombing of civilian targets without military value, in the hope of damaging an enemy's morale. One of the strategies of war is to demoralize the enemy so that peace or surrender becomes preferable to continuing the conflict. Strategic bombing has been used to this end. The phrase "terror bombing" entered the English lexicon towards the end of World War II and many strategic bombing campaigns and individual raids have been described as terror bombing by comment ...

Wing (air Force 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 "squadron ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-17 Flying Fortress
The Boeing B-17 Flying Fortress is a four-engined heavy bomber developed in the 1930s for the United States Army Air Corps (USAAC). Relatively fast and high-flying for a bomber of its era, the B-17 was used primarily in the European Theater of Operations and dropped more bombs than any other aircraft during World War II. It is the third-most produced bomber of all time, behind the four-engined Consolidated B-24 Liberator and the multirole, twin-engined Junkers Ju 88. It was also employed as a transport, antisubmarine aircraft, drone controller, and search-and-rescue aircraft. In a USAAC competition, Boeing's prototype Model 299/XB-17 outperformed two other entries but crashed, losing the initial 200-bomber contract to the Douglas B-18 Bolo. Still, the Air Corps ordered 13 more B-17s for further evaluation, then introduced it into service in 1938. The B-17 evolved through numerous design advances but from its inception, the USAAC (later, the USAAF) promoted the aircraft ...

Fire Bombing
Firebombing is a bombing technique designed to damage a target, generally an urban area, through the use of fire, caused by incendiary devices, rather than from the blast effect of large bombs. In popular usage, any act in which an incendiary device is used to initiate a fire is often described as a "firebombing". This article is concerned with aerial incendiary bombing as a military tactic; for non-military (almost always criminal) acts, see ''arson''. Although simple incendiary bombs have been used to destroy buildings since the start of gunpowder warfare, World War I saw the first use of strategic bombing from the air to damage the morale and economy of the enemy, such as the German Zeppelin air raids conducted on London during the Great War. The Chinese wartime capital of Chongqing was firebombed by the Imperial Japanese starting in early 1939. London, Coventry, and many other British cities were firebombed during the Blitz by Germany. Most large German cities were extensiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Area Bombing
In military aviation, area bombardment (or area bombing) is a type of aerial bombardment in which bombs are dropped over the general area of a target. The term "area bombing" came into prominence during World War II. Area bombing is a form of strategic bombing. It can serve several intertwined purposes: to disrupt the production of military materiel, to disrupt lines of communications, to divert the enemy's industrial and military resources from the primary battlefield to air defence and infrastructure repair, and to demoralise the enemy's population (See terror bombing). "Carpet bombing",An early example of this use of "carpet bombing" is from 1942: also known as "saturation bombing", and "obliteration bombing", refers to a type of area bombing that aims to effect complete destruction of the target area by exploding bombs in every part of it. Area bombing is contrasted with precision bombing. The latter is directed at a selected target – not necessarily a small, and not ...

Curtis LeMay
Curtis Emerson LeMay (November 15, 1906 – October 1, 1990) was an American Air Force general who implemented a controversial strategic bombing campaign in the Pacific theater of World War II. He later served as Chief of Staff of the U.S. Air Force, from 1961 to 1965. LeMay joined the U.S. Army Air Corps, the precursor to the U.S. Air Force, in 1929 while studying civil engineering at Ohio State University. He had risen to the rank of major by the time of Japan's Attack on Pearl Harbor in December 1941 and the United States's subsequent entry into World War II. He commanded the 305th Operations Group from October 1942 until September 1943, and the 3rd Air Division in the European theatre of World War II until August 1944, when he was transferred to the China Burma India Theater. He was then placed in command of strategic bombing operations against Japan, planning and executing a massive fire bombing campaign against Japanese cities and Operation Starvation, a crippling min ...

Jet Stream
Jet streams are fast flowing, narrow, meandering air currents in the atmospheres of some planets, including Earth. On Earth, the main jet streams are located near the altitude of the tropopause and are westerly winds (flowing west to east). Jet streams may start, stop, split into two or more parts, combine into one stream, or flow in various directions including opposite to the direction of the remainder of the jet. Overview The strongest jet streams are the polar jets around the polar vortices, at above sea level, and the higher altitude and somewhat weaker subtropical jets at . The Northern Hemisphere and the Southern Hemisphere each have a polar jet and a subtropical jet. The northern hemisphere polar jet flows over the middle to northern latitudes of North America, Europe, and Asia and their intervening oceans, while the southern hemisphere polar jet mostly circles Antarctica, both all year round. Jet streams are the product of two factors: the atmospheric heating b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strategic Air Command
Strategic Air Command (SAC) was both a United States Department of Defense Specified Command and a United States Air Force (USAF) Major Command responsible for command and control of the strategic bomber and intercontinental ballistic missile components of the United States military's strategic nuclear forces from 1946 to 1992. SAC was also responsible for the operation of strategic reconnaissance aircraft and airborne command post aircraft as well as most of the USAF's aerial refueling fleet, including aircraft from the Air Force Reserve (AFRES) and Air National Guard (ANG). SAC primarily consisted of the Second Air Force (2AF), Eighth Air Force (8AF) and the Fifteenth Air Force (15AF), while SAC headquarters (HQ SAC) included Directorates for Operations & Plans, Intelligence, Command & Control, Maintenance, Training, Communications, and Personnel. At a lower echelon, SAC headquarters divisions included Aircraft Engineering, Missile Concept, and Strategic Communicati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twentieth Air Force
The Twentieth Air Force (Air Forces Strategic) (20th AF) is a numbered air force of the United States Air Force Global Strike Command (AFGSC). It is headquartered at Francis E. Warren Air Force Base, Wyoming. 20 AF's primary mission is Intercontinental Ballistic Missile (ICBM) operations. The Twentieth Air Force commander is also the Commander, Task Force 214 (TF 214), which provides alert ICBMs to the United States Strategic Command (USSTRATCOM). Established on 4 April 1944 at Washington D.C, 20 AF was a United States Army Air Forces combat air force deployed to the Pacific Theater of World War II. Operating initially from bases in India and staging through bases in China, 20 AF conducted strategic bombardment of the Japanese Home Islands. It relocated to the Mariana Islands in late 1944, and continued the strategic bombardment campaign against Japan until the Japanese capitulation in August 1945. The 20 AF 509th Composite Group conducted the atomic attacks on Hiroshima an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mariana Islands
The Mariana Islands (; also the Marianas; in Chamorro: ''Manislan Mariånas'') are a crescent-shaped archipelago comprising the summits of fifteen longitudinally oriented, mostly dormant volcanic mountains in the northwestern Pacific Ocean, between the 12th and 21st parallels north and along the 145th meridian east. They lie south-southeast of Japan, west-southwest of Hawaii, north of New Guinea and east of the Philippines, demarcating the Philippine Sea's eastern limit. They are found in the northern part of the western Oceanic sub-region of Micronesia, and are politically divided into two jurisdictions of the United States: the Commonwealth of the Northern Mariana Islands and, at the southern end of the chain, the territory of Guam. The islands were named after the influential Spanish queen Mariana of Austria following their colonization in the 17th century. The indigenous inhabitants are the Chamorro people. Archaeologists in 2013 reported findings which indicated that th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
B-29 Superfortress
The Boeing B-29 Superfortress is an American four-engined propeller-driven heavy bomber, designed by Boeing and flown primarily by the United States during World War II and the Korean War. Named in allusion to its predecessor, the B-17 Flying Fortress, the Superfortress was designed for high-altitude strategic bombing, but also excelled in low-altitude night incendiary bombing, and in dropping naval mines to blockade Japan. B-29s dropped the atomic bombs on Hiroshima and Nagasaki, the only aircraft ever to drop nuclear weapons in combat. One of the largest aircraft of World War II, the B-29 was designed with state-of-the-art technology, which included a pressurized cabin, dual-wheeled tricycle landing gear, and an analog computer-controlled fire-control system that allowed one gunner and a fire-control officer to direct four remote machine gun turrets. The $3 billion cost of design and production (equivalent to $ billion today), far exceeding the $1.9 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
