This is the plane that almost beat out the legendary F-16

You may know Chuck Yeager as the man who broke the sound barrier, but back in the 1980s, he was also pitching a new fighter jet — one that arguably would have been on par with modern fighters like the F-16.

That jet was the Northrop F-20 Tigershark. First known as the F-5G, it was a program to give American allies an advanced multi-role fighter to replace older F-5E/F Tiger IIs. The Tiger was a good plane, but arguably at a disadvantage against jets like the MiG-23 Flogger. The Soviet Union was also widely exporting the MiG-21 Fishbed and the world needed a response.

American allies had a problem, though. Under President Jimmy Carter, the United States would not release the F-15 Eagle or F-16 Fighting Falcon to many of them. Israel got lucky, and was able to buy the planes, but most other allies had to settle for something less capable. Northrop's privately-funded venture fit the bill.

The F-20 replaced the two J85 turbojet engines typical of the F-5E with a single F404 turbofan, like those used on the F/A-18. It also had the ability to fire the AIM-7 Sparrow, a semi-active radar-guided missile. Northrop also got Chuck Yeager to serve as the pitchman.

The F-20 proved to be very easy to maintain, was cheap (aviation historian Joe Baugher notes that a $15 million per plane price tag was quoted), and had a number of advances that made it a capable interceptor. MilitaryFactory.com notes that the F-20 had a top speed of 1,500 miles per hour and a range of 1,715 miles. Three prototypes were built, and a fourth would have had more fuel capacity and the ability to use drop tanks.

The problem was, even with Chuck Yeager pitching it, the Air Force and Navy didn't want the plane. The last chance for this plane's success came and went when the Air National Guard declined to replace F-106 Delta Darts and F-4 Phantoms with it, opting instead for modified F-16s.
