One of the Greatest Fighters that Never Was- F-20 Tigershark

Originally concieved as an improved F-5 Tiger, the F-20 Tigershark was a Northrup product intended for sales to overseas customers. Replacing the twin J85 turbojets of the F-5 with the F404 turbofan engine, the F-20 was a real hotrod.

Unfortunately, it was also about the same time that our NATO allies jumped whole hog into production of the F-16, coupled with sales of French and other fighters. The market timing was off, and the Tigershark never went into serial production.
