The United States Air Force (USAF) is the aerial warfare branch of the armed forces and one of the seven uniformed services of the United States. Initially part of the United States Army as the Army Air Corps, the USAF was formed as a separate branch of the military on September 18, 1947. It was the last branch of the US military to be formed.
The USAF is one of the largest and most technologically advanced air forces in the world, with about 5,573 manned aircraft in service (3,990 USAF; 1,213 Air National Guard; and 370 Air Force Reserve); approximately 180 Unmanned Combat Air Vehicles, 2130 Air-Launched Cruise Missiles, and 450 Intercontinental Ballistic Missiles; and has 330,159 personnel on active duty, 68,872 in the Selected and Individual Ready Reserves, and 94,753 in the Air National Guard. In addition, the Air Force employs 151,360 civilian personnel.
The Department of the Air Force is headed by the civilian Secretary of the Air Force who heads administrative affairs. The Department of the Air Force is a division of the Department of Defense, headed by the Secretary of Defense. The highest ranking military officer in the Department of the Air Force is the Chief of Staff of the Air Force.
Service considering retrofitting late-model C-130's with new engines
Summary: The U.S. Air Force is interested in procuring commercial off-the-shelf engines to replace antiquated propulsion systems on C-130 aircraft. At a technology summit in Arlington, Virginia, General Philip Breedlove told of the service's efforts to follow up on the successes of the C-130J upgrade with commercially available fuel efficient engines. Breedlove says the prioritization of use of C-130J's in inter-theater operations for cost savings has tied up logistics. The C-130 also suffers from performance and maintenance issues that have led to the cancellation of the FCS Manned Ground Vehicles program that was unable to fall within weight parameters while maintaining protection requirements. While enhancing the current generation of aircraft, the Air Force is also heading an initiative to develop fuel efficient technologies for the next generation of propulsion systems. the ADaptive Versatile ENgine Technology program seeks to develop an engine that is 30% more efficient than the F119 or F135 engines that power the F-35 Lightning II and F-22 Raptor fifth-generation stealth fighter aircraft. The Versatile, Affordable, Advanced Turbine Engines and Highly Efficient Embedded Turbine Engine programs are also being pursued to develop propulsion technologies for sub-sonic military aircraft.
