The Lightweight Fighter (LWF) program was a U.S. Air Force technology evaluation program initiated in the 1960s by a cabal of officers and defense analysts known as the "Fighter Mafia". It was spurred by then Major John Boyd's Energy-Maneuverability (E-M) theory of maneuverability, which indicated that excessive weight would have severely debilitating consequences on the maneuverability of an aircraft. Boyd's design called for a light-weight fighter with a high thrust-to-weight ratio, a gross weight of less than 20,000 pounds (9,100 kg) (half that of its counterpart, the F-15 Eagle), and high maneuverability. It resulted in the development of the General Dynamics YF-16 and Northrop YF-17. Late in the program, in 1974, with the promise of European sales, the Air Force changed the program name to Air Combat Fighter (ACF), and committed to purchasing 650 models of the YF-16, adopted as the F-16 Fighting Falcon. The U.S. Navy adopted a modified version of the YF-17 as the F/A-18 Hornet.
Famous quotes containing the words fighter and/or program:
“A pleasant smell of frying sausages
Attacks the sense, along with an old, mostly invisible
Photograph of what seems to be girls lounging around
An old fighter bomber, circa 1942 vintage.”
—John Ashbery (b. 1927)
“The westerner, normally, walks to get somewhere that he cannot get in an automobile or on horseback. Hiking for its own sake, for the sheer animal pleasure of good condition and brisk exercise, is not an easy thing for him to comprehend.”
—State of Utah, U.S. public relief program (1935-1943)
