Military airbase

An military airbase (sometimes referred to as a military airfield, military airport, air force station, air force base or short airbase) is an aerodrome used by a military force for the operation of military aircraft.

Airbase facilities

An airbase typically has some facilities similar to a civilian airport—for example air traffic control and firefighting. Some military aerodromes have passenger facilities; for example RAF Brize Norton in England has a terminal used by passengers for the Royal Air Force's flights by TriStar to the Falkland Islands. A number of military airbases also have a civil enclave for commercial passenger flights, e.g. Beijing Nanyuan Airport (China), Ibaraki Airport (Japan), Burlington International Airport (USA).

Some airbases have revetments, hardened aircraft shelters, or even underground hangars, to protect aircraft from enemy attack. Combat aircraft require storage of aircraft ordnance. An airbase may be defended by anti-aircraft weapons and force protection troops.

Air force

An air force, also known in some countries as an air army, is in the broadest sense, the national military organization that primarily conducts aerial warfare. More specifically, it is the branch of a nation's armed services that is responsible for aerial warfare as distinct from an army, navy, or a marine corps. Typically, air forces are responsible for gaining control of the air, carrying out strategic and tactical bombing missions, and providing support to land and naval forces.

The term "air force" may also refer to a tactical air force or numbered air force, which is an operational formation either within a national air force or comprising several air components from allied nations. Air forces typically consist of a combination of fighters, bombers, helicopters, transport planes and other aircraft.

Many air forces are also responsible for operations of the military space, intercontinental ballistic missiles (ICBM), and communications equipment. Some air forces may command and control other air defence assets such as anti-aircraft artillery, surface-to-air missiles, or anti-ballistic missile warning networks and defensive systems. Some nations, principally Russia, the former Soviet Union and countries who modelled their militaries along Soviet lines, have an air defence force which is organizationally separate from their air force.

Osan Air Base

Osan Air Base (K-55; Korean: 오산공군기지; Hanja: 烏山空軍基地), is a United States Air Force base located near Songtan Station in the county of Pyeongtaek, South Korea, 64 km (40 mi) south of Seoul. Despite its name, Osan AB is not within Osan City, which is 7.5 km (4.7 mi) to the north. The base is the home of the Pacific Air Forces' 51st Fighter Wing, and a number of tenant units, including the headquarters for Seventh Air Force. The base is also the headquarters of the ROK Air Force Operations Command. Osan Air Base is also the departure and arrival point for U.S. government-contracted "Patriot Express" flights bringing service members and their family members to South Korea from Seattle-Tacoma International Airport in the U.S. state of Washington, Misawa Air Base and Yokota Air Base in Japan.

As the most forward deployed permanently based wing in the Air Force, and equipped with A-10 Thunderbolt IIs and F-16 Fighting Falcons, the 51st Fighter Wing is charged with executing combat operations, receiving follow-on forces and defending the base from attack. As the air component to United States Forces Korea and Combined Forces Command, 7th Air Force provides the command and control structures and personnel necessary to deliver precise, persistent, combined air and space power in defense of the Republic of Korea.

US Airways

US Airways was a major American airline that ceased operations on October 17, 2015 after merging with American Airlines. It operated an extensive international and domestic network, with 193 destinations in 24 countries in North America, South America, Europe and the Middle East. The airline was an affiliate member of Oneworld and utilized a fleet of 343 mainline jet aircraft, as well as 278 regional jet and turbo-prop aircraft operated by contract and subsidiary airlines under the name US Airways Express.

The carrier operated the US Airways Shuttle, a US Airways brand which provided hourly service between Boston, New York City and Washington, D.C. As of October 2013, US Airways employed 32,312 people worldwide and operated 3,028 daily flights (1,241 US Airways Mainline, 1,790 US Airways Express) Roughly 60% of US Airways flights were operated by US Airways Express.

In 1979, after passage of the Airline Deregulation Act, Allegheny Airlines changed its name to USAir and began seeking to expand its operations. A decade later, it had acquired Piedmont Airlines and Pacific Southwest Airlines, and was one of the U.S.'s seven remaining transcontinental legacy carriers. In 2005, America West Airlines carried out a reverse merger, acquiring the assets and branding of the larger US Airways while putting the America West leadership team largely in charge of the merged airline.

United States Air Force

The United States Air Force (USAF) is the aerial warfare service branch of the United States Armed Forces and one of the seven American uniformed services. Initially part of the United States Army, the USAF was formed as a separate branch of the military on 18 September 1947 under the National Security Act of 1947. It is the most recent branch of the U.S. military to be formed, and is the largest and one of the world's most technologically advanced air forces. The USAF articulates its core functions as Nuclear Deterrence Operations, Special Operations, Air Superiority, Global Integrated ISR, Space Superiority, Command and Control, Cyberspace Superiority, Personnel Recovery, Global Precision Attack, Building Partnerships, Rapid Global Mobility and Agile Combat Support.

The U.S. Air Force is a military service organized within the Department of the Air Force, one of the three military departments of the Department of Defense. The Air Force is headed by the civilian Secretary of the Air Force, who reports to the Secretary of Defense, and is appointed by the President with Senate confirmation. The highest-ranking military officer in the Department of the Air Force is the Chief of Staff of the Air Force, who exercises supervision over Air Force units, and serves as a member of the Joint Chiefs of Staff. Air Force combat and mobility forces are assigned, as directed by the Secretary of Defense, to the Combatant Commanders, and neither the Secretary of the Air Force nor the Chief of Staff have operational command authority over them.
