Northrop's F-20 Tigershark, an evolution of the company's highly successful F-5E Tiger II—which itself was an evolution of the F-5A/B Freedom Fighter and The T-38 Talon—never made it into production, but many thought it should have. The aircraft provided high performance and multi-role capability on the cheap, both in terms of procurement and operating costs. But the Reagan administration's loosening of export rules on military equipment, including fighters, allowed the already deep into production, larger and more advanced F-16 to edge out the F-20 on the world-wide fighter jet marketplace.
