The YF-17 Cobra was a Northrop Aviation creation through NASA to support further testing and research of aircraft at transonic speeds (meaning just underneath the speed of sound, or 700-780mph / 1,127-1,255kph). The YF-17 Cobra was, itself, born from the United States Air Force's Lightweight Fighter Program.

The Lightweight Fighter Program called for a prototype that was small and low cost / maintenance, with the capabilities of an air superiority day fighter. Though losing out to the General Dynamics YF-16 (later to become the F-16 Fighting Falcon), the YF-17 would see bluer skies in the form of the later F/A-18 Hornet aboard the carrier of the United States Navy.

After the failed LWF fly-off competition for the YF-17 Cobra, tests began with NASA over a seven week period that included in-flight pressure data recorded through sensors from all over the aircraft airframe, studies in transonic maneuverability, and stability and control factors in controlled forty-five minute long flights.

In the end, the YF-17 Cobra would set the stage for the first prototypes and production models of the highly successful F/A-18 series of aircraft, leading up to the "Super Hornet" design and the eventual successor to the much regarded F-14 Tomcat series of carrier-based interceptors.
