Airpower or air power consists of the application of military aviation, military strategy and strategic theory to the realm of aerial warfare and close air support. Airpower began in the advent of powered flight early in the 20th century. Airpower represents a "complex operating environment that has been subjected to considerable debate". [1] [2] British doctrine defines airpower as "the ability to project power from the air and space to influence the behaviour of people or the course of events." [1] The Australian Experience of Air Power defines Airpower as being composed of Control of the Air, Strike, Intelligence Surveillance and Reconnaissance, and Air Mobility roles. [3]
Airpower can be considered a function of air supremacy and numbers. Roughly speaking, a combatant side that has 100% or near 100% control of the skies has air supremacy; an advantage of some 70–90% would indicate air superiority. A 50/50 split is air parity; lower than this, one side may be said to be air denied or air incapable. Because aeroplanes generally take off from designed airfields on missions typically involving some hours of cruising, the precise state of air superiority is fluid and less defined vis-a-vis land or sea warfare. For example, a contested airspace directly above a battlespace bristling with anti-aircraft weapons may be denied to the air forces of both sides. Further, the completely different situations of a technologically advanced airforce with one flight of high-tech planes (air supremacy but low capacity) or a low-tech force of massive numbers of low-tech planes (e.g., An-2) resulting in high capacity but low long-term survivability demonstrate that 'air power' is multi-faceted and complex.
Significant contributors to theorizing about air power have been Giulio Douhet, Billy Mitchell, John Boyd and John A. Warden III.
At the start of World War I, opinions differed on the national air forces and the value of airships. [4] [5] Some early strategists/visionaries after World War I imagined that airpower alone would suffice to bring nations to their knees. The Bombing of Guernica was an early trial that revealed both capabilities and limitations. But yet another maxim, "no war was ever won solely by airpower" was challenged by the NATO victory in Kosovo. Airpower has been used to conduct lightning strategic strikes, to complement land offensives, to instill fear and lower morale similarly to a fleet in being, and to create broad-based destruction behind enemy lines. With airpower, supplies can be transported by cargo planes, providing a decisive edge in mobility.
Military and civilian aircraft interact in a number of complex ways, including shootdowns of civilian planes, whether mistaken or not; military escorts of civilian planes; civilian planes being used for military transport, espionage, or other purposes; and/or no-fly zones being enforced to punish or sanction a target nation. Airpower also relates to space power, although militarization of space remains regulated by international treaty.[ citation needed ]
Developed nations have enjoyed a consistent advantage in airpower since the beginning of mechanized flight. Airpower has been wielded mostly decisively in the last hundred years by Nazi Germany, the United Kingdom, the United States, the Soviet Union, Japan, Italy, and France, with many client nations using aircraft developed by one or more of these nations. A mass technological base is considered necessary for the development of airpower.
The United States Air Force (USAF) is the air service branch of the United States Armed Forces, and is one of the eight uniformed services of the United States. Originally created on 1 August 1907, as a part of the United States Army Signal Corps, the USAF was established as a separate branch of the United States Armed Forces in 1947 with the enactment of the National Security Act of 1947. It is the second youngest branch of the United States Armed Forces and the fourth in order of precedence. The United States Air Force articulates its core missions as air supremacy, global integrated intelligence, surveillance and reconnaissance, rapid global mobility, global strike, and command and control.
Strategic bombing 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. It 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. 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.
Military tactics encompasses the art of organizing and employing fighting forces on or near the battlefield. They involve the application of four battlefield functions which are closely related – kinetic or firepower, mobility, protection or security, and shock action. Tactics are a separate function from command and control and logistics. In contemporary military science, tactics are the lowest of three levels of warfighting, the higher levels being the strategic and operational levels. Throughout history, there has been a shifting balance between the four tactical functions, generally based on the application of military technology, which has led to one or more of the tactical functions being dominant for a period of time, usually accompanied by the dominance of an associated fighting arm deployed on the battlefield, such as infantry, artillery, cavalry or tanks.
General Giulio Douhet was an Italian general and air power theorist. He was a key proponent of strategic bombing in aerial warfare. He was a contemporary of the air warfare advocates Walther Wever, Billy Mitchell, and Hugh Trenchard.
Aerial warfare is the use of military aircraft and other flying machines in warfare. Aerial warfare includes bombers attacking enemy installations or a concentration of enemy troops or strategic targets; fighter aircraft battling for control of airspace; attack aircraft engaging in close air support against ground targets; naval aviation flying against sea and nearby land targets; gliders, helicopters and other aircraft to carry airborne forces such as paratroopers; aerial refueling tankers to extend operation time or range; and military transport aircraft to move cargo and personnel.
A no-fly zone, also known as a no-flight zone (NFZ), or air exclusion zone (AEZ), is a territory or area established by a military power over which certain aircraft are not permitted to fly. Such zones are usually set up in an enemy power's territory during a conflict for humanitarian or military reasons without consent of the enemy state, similar in concept to an aerial demilitarized zone, and usually intend to prohibit the enemy's military aircraft from operating in the region. Military action is employed by the enforcing state and, depending on the terms of the NFZ, may include preemptive attacks to prevent potential violations, reactive force targeted at violating aircraft, or surveillance with no use of force. Air exclusion zones and anti-aircraft defences are sometimes set up in a civilian context, for example to protect sensitive locations, or events such as the 2012 London Olympic Games, against terrorist air attack. A no-fly zone is generally not considered a form of aerial blockade due to its more limited scope compared to an aerial blockade.
Aerial supremacy is the degree to which a side in a conflict holds control of air power over opposing forces. There are levels of control of the air in aerial warfare. Control of the air is the aerial equivalent of command of the sea.
In military tactics, close air support (CAS) is defined as aerial warfare actions—often air-to-ground actions such as strafes or airstrikes—by military aircraft against hostile targets in close proximity to friendly forces. A form of fire support, CAS requires detailed integration of each air mission with fire and movement of all forces involved. CAS may be conducted using aerial bombs, glide bombs, missiles, rockets, autocannons, machine guns, and even directed-energy weapons such as lasers.
A trainer is a class of aircraft designed specifically to facilitate flight training of pilots and aircrews. The use of a dedicated trainer aircraft with additional safety features—such as tandem flight controls, forgiving flight characteristics and a simplified cockpit arrangement—allows pilots-in-training to safely advance their skills in a more forgiving aircraft.
Naval aviation is the application of military air power by navies, whether from warships that embark aircraft, or land bases.
Fourth-generation warfare (4GW) is conflict characterized by a blurring of the distinction between war and politics, and of the distinction between combatants and civilians. It is placed as succeeding the third generation in the five-generation model of military theory.
In military science, force multiplication or a force multiplier is a factor or a combination of factors that gives personnel or weapons the ability to accomplish greater feats than without it. The expected size increase required to have the same effectiveness without that advantage is the multiplication factor. For example, if a technology like GPS enables a force to accomplish the same results as a force five times as large without GPS, then the multiplier is five. Such estimates are used to justify the investment for force multipliers.
Bill Sweetman is a former editor for Jane's and currently an editor for Aviation Week group. He is a writer of more than 50 books on military aircraft. He lives in Oakdale, Minnesota. He is noted for his dogged pursuit of the Aurora project. He appeared as an Aerospace Consultant on in the Nova PBS TV program "Battle of the X-Planes" about the Joint Strike Fighter Program.
Bill Gunston was a British aviation and military author. He flew with Britain's Royal Air Force from 1945 to 1948, and after pilot training became a flying instructor. He spent most of his adult life doing research and writing on aircraft and aviation. He was the author of over 350 books and articles. His work included many books published by Salamander Books.
John Ashley Warden III is a retired colonel in the United States Air Force. Warden is a graduate of the United States Air Force Academy. His Air Force career spanned 30 years, from 1965 to 1995, and included tours in Vietnam, Germany, Spain, Italy, and Korea, as well as many assignments within the continental United States. Warden completed a number of assignments in the Pentagon, was a Special Assistant for Policy Studies and National Security Affairs to the Vice President of the United States, and was Commandant of the Air Command and Staff College.
Phillip S. Meilinger is a retired colonel of the USAF as well as a historian and analyst. He is a member of the Academic Advisory Panel of the Royal Air Force Centre for Air Power Studies. Before his retirement he was Dean of the School of Advanced Airpower Studies (SAAS) at the USAF's Air University in Montgomery, Alabama. He received a BS degree from the United States Air Force Academy, an MA degree from the University of Colorado, and obtained a PhD degree in military history from the University of Michigan. A command pilot, he has served as a C-130 aircraft commander and instructor pilot in both Europe and the Pacific. After a tour at the Air Force Academy, he was assigned to the Doctrine Division of the Air Staff at the Pentagon. He has authored ten books and scores of articles. Perhaps best known is his edited work, The Paths of Heaven: The Evolution of Airpower Theory (1997). In an attempt to create debate and more reflection about the inherent characteristics of air power, in 1995 Dr Meiling wrote Ten Propositions on Airpower, a small and influential booklet advocating what he considers to be the air power equivalent of Principles of War. Among his many articles is:"Winged Defence: Answering the Critics of Airpower."Air Power Review Vol. 5 No. 4, pp. 41–64.
The Pratt & Whitney T34 was an American axial flow turboprop engine designed and built by Pratt & Whitney. Its only major application was on the Douglas C-133 Cargomaster.
Aerospace engineering is the primary field of engineering concerned with the development of aircraft and spacecraft. It has two major and overlapping branches: aeronautical engineering and astronautical engineering. Avionics engineering is similar, but deals with the electronics side of aerospace engineering.
Air warfare was a major component in all theaters of World War II and, together with anti-aircraft warfare, consumed a large fraction of the industrial output of the major powers. Germany and Japan depended on air forces that were closely integrated with land and naval forces; the Axis powers downplayed the advantage of fleets of strategic bombers and were late in appreciating the need to defend against Allied strategic bombing. By contrast, Britain and the United States took an approach that greatly emphasized strategic bombing and tactical control of the battlefield by air as well as adequate air defenses. Both Britain and the U.S. built substantially larger strategic forces of large, long-range bombers. Simultaneously, they built tactical air forces that could win air superiority over the battlefields, thereby giving vital assistance to ground troops. The U.S. Navy and Royal Navy also built a powerful naval-air component based on aircraft carriers, as did the Imperial Japanese Navy; these played the central role in the war at sea.
David A. Deptula is the Dean of the Mitchell Institute for Aerospace Power Studies, and a senior scholar at the U.S. Air Force Academy's Center for Character and Leadership Development. He transitioned from the U.S. Air Force in 2010 at the rank of Lieutenant General after more than 34 years of service. Deptula was commissioned in 1974 as a distinguished graduate from The University of Virginia Air Force ROTC program, and remained to complete a master's degree in 1976. During his military career he took part in operations, planning, and joint warfighting at unit, major command, service headquarters and combatant command levels, and also served on two congressional commissions outlining America's future defense posture. He was a principal author of the original Air Force White Paper "Global Reach—Global Power". In the early 1990s he was instrumental in the formation and development of the concept later known as "effects-based operations", having successfully applied it in building the attack plans for the Operation Desert Storm air campaign. He has been cited as having "... fostered the most significant change in the conduct of aerial warfare since Billy Mitchell...Deptula’s framework influenced the successful air campaigns in Operations Allied Force, Iraqi Freedom, and Enduring Freedom. Today, joint targeting cells and Air Force doctrine reflect Deptula's theory of airpower and the changing nature of warfare." Deptula is one of 12 airmen singled out in Airpower Pioneers: From Billy Mitchell to Dave Deptula. He is also the subject of a more detailed review of his contributions to the development of airpower in America's Airman: David Deptula and the Airpower Moment.
