F16 Horrible Super Speed Aerobatics !!
Genesis of the successful F-16 fighter/attack aircraft lies in reaction to severe deficiencies in US fighter design revealed by the Vietnam War.
Following the success of the small, highly maneuverable F-86 day fighter in the Korean War, US fighter design changed to emphasize maximum speed, altitude, and radar capability at the expense of maneuverability, pilot vision, and other attributes needed for close combat. This trend reached its extremity in the McDonnell Douglas F-4 Phantom, which was the principal fighter for both the US Air Force and Navy during the latter part of the Vietnam War.
These various sacrifices were rationalized by the belief that visual dogfighting was obsolete, and that in the supersonic age, air combat would be fought beyond visual range (BVR) using radar-guided missiles. This concept failed in Vietnam for two reasons: First, radar could detect and track aircraft but not identify them. Operating beyond visual range created an unacceptable risk of shooting down one's own aircraft. Pilots were therefore required to close to visually identify the target before shooting; this eliminated the theoretical range advantage of radar-guided missiles. Second, the performance of the Sparrow radar-guided missile in Vietnam was poor, generally yielding less than 10% kill per shot.
The original F-15 had excellent pilot vision, including being able to see 360 degrees in the horizontal plane. It had strong high-speed maneuverability and a 20mm cannon. In addition to rectifying some of the F-4's deficiencies, it could fly higher and faster than the F-4, and had dramatically better climb and acceleration.
It also had a powerful radar with advanced look-down shoot-down capability, and relied on the Sparrow missile as its principal weapon.
What the Air Force needed, the Mafia argued, was a successor to the WWII P-51 Mustang and the Korean War F-86 Saber: an all-new small fighter that would be cheap enough to buy in large numbers. (The F-104 was not considered a predecessor aircraft because, while it had excellent climb and acceleration, its wings were too small, leaving it deficient in range and maneuverability.) The new fighter would have revolutionary maneuverability, transient performance, acceleration, and climb at the subsonic and transonic speeds at which air combat is actually fought. It would have a gun and its primary armament would be the infra-red guided Sidewinder missile that had proven highly effective in Vietnam.
In any case, the Air Force establishment wanted no part of a new small fighter, with or without radar. It was regarded as a threat to the F-15, which was USAF's highest priority program. But the Fighter Mafia gained considerable resonance in Congress and within the Office of the Secretary of Defense. In 1971 Deputy Secretary of Defense David Packard began a Lightweight Fighter (LWF) program to explore the concept.
