Air refueling significantly expands the options available to a commander by increasing the range, payload, persistence, and flexibility of receiver aircraft. Aeromedical evacuation is "the movement of patients under medical supervision to and between medical treatment facilities by air transportation" (JP 1-02). JP 4-02, Health Service Support, further defines it as "the fixed wing movement of regulated casualties to and between medical treatment facilities, using organic and/or contracted mobility airframes, with aircrew trained explicitly for this mission." Aeromedical evacuation forces can operate as far forward as fixed-wing aircraft are able to conduct airland operations. Global precision attack

The purpose of all of these core missions
1674-650: The Six-Day War of 1967, when the Heyl Ha'avir destroyed a large portion of the air power of Egypt , Syria , and Jordan , mostly on the ground, totaling roughly 600 airframes destroyed by a force of 200 aircraft. However, in sheer number of planes destroyed, the opening two weeks of Operation Barbarossa saw some 3-4,000 Russian planes destroyed in total. Other successful attacks include US counter-air operations in Korea in 1950 and 1953, French and British attacks during

However, there have also been notable failures like Operation Chengiz Khan initiated by Pakistan during the Indo-Pakistani War of 1971 and Iraqi attacks on Iran. Although OCA missions are often carried out via air strikes, they are not limited to aerial action. The Teishin Shudan and Giretsu Kuteitai commandos carried out two notable OCA raids during World War II, as did
1798-575: The 1950s, the Cold War strategy of both NATO and the Warsaw Pact called for OCA to be carried out with tactical nuclear weapons , but by the mid-1960s, new policies of 'proportional response' brought about a return to conventional tactics. Beginning shortly before the Six-Day War , specialized weapons were developed for disrupting runways, such as the BLU-107 Durandal anti-runway bomb. Various such weapons continue to be fielded, notably

Prior to 1947, the responsibility for military aviation was shared between the Army Air Forces and its predecessor organizations (for land-based operations), the Navy (for sea-based operations from aircraft carriers and amphibious aircraft), and the Marine Corps (for close air support of Marine Corps operations). The 1940s proved to be important for military aviation in other ways as well. In 1947, Air Force Captain Chuck Yeager broke
2108-461: The ROMO. The purpose of nuclear deterrence operations (NDO) is to operate, maintain, and secure nuclear forces to achieve an assured capability to deter an adversary from taking action against vital US interests. In the event deterrence fails, the US should be able to appropriately respond with nuclear options. The sub-elements of this function are: Assure/Dissuade/Deter is a mission set derived from
2170-543: The US determines national or multinational security objectives and guidance, and develops and uses national resources to accomplish these objectives. These national objectives in turn provide the direction for developing overall military objectives, which are used to develop the objectives and strategy for each theater. At the operational level command and control, campaigns and major operations are planned, conducted, sustained, and assessed to accomplish strategic goals within theaters or areas of operations. These activities imply

The size of the active duty force in 2007 was roughly 64% of that of what the USAF was at the end of the first Gulf War in 1991. However, the reduction was ended at approximately 330,000 personnel in 2008 in order to meet the demand signal of combatant commanders and associated mission requirements. These same constraints have seen

The U.S. War Department created the first antecedent of the U.S. Air Force, as a part of the U.S. Army, on 1 August 1907, which through a succession of changes of organization, titles, and missions advanced toward eventual independence 40 years later. In World War II , almost 68,000 U.S. airmen died helping to win
2852-479: The enemy holds dear in a devastating manner. If a crisis occurs, rapid generation and, if necessary, deployment of nuclear strike capabilities will demonstrate US resolve and may prompt an adversary to alter the course of action deemed threatening to our national interest. Should deterrence fail, the President may authorize a precise, tailored response to terminate the conflict at the lowest possible level and lead to
2914-483: The fire and movement of friendly forces is not required" (Annex 3-03, Counterland Operations). Close Air Support is defined as "air action by fixed- and rotary-winged aircraft against hostile targets that are in close proximity to friendly forces and which require detailed integration of each air mission with the fire and movement of those forces" (JP 1-02). This can be as a pre-planned event or on demand from an alert posture (ground or airborne). It can be conducted across
