Considering the obvious need for an effective, low-cost fighter concept, and the fact that the legendary F5 series is finally reaching it's sunset, I wonder if Northrop might consider re-investigating their failed F-20 Tigershark with an eye on bringing it back as an export item for air-forces like  the Philippines who need high performance at low cost.

The F-20 was a brilliant concept, Not really! combining the best features of the efficient, reliable and easy to maintain F-404 engine with the well designed and robust F5 airframe, offering true mach 2 performance Not really! It never held enough gas to get it done! with an airframe that could take on insane maneuvers and still hold together. The F-5 was never the most maneuverable of planes and all the up-grades did not fix those problems. The problem, at the time of it's introduction in the 1980s, was the F-16, though more expensive, simply outperformed the updated 1960s era design.  (But not by much.) This is a common misconception based on the published "Plackard" data and ignores all of the other more important factors. That, and the fact that so many cheap, F5-Tiger IIs were already glutting the second hand fighter market.  Now we see that some Nations, like the Philippines, Taiwan and others are finding it difficult to even keep the F-16 in the air, and the last of the Tiger-IIs have finally worn out, leaving a hole in the low-cost market.  The only other low-cost fighter out there is the Chinese JF-17, and the F-20 could run circles around it.  (And that's with 1980s technology!)  Just upgrade to the F-414 engine and update the electronics and radar to put it into the 21st century, and the F-20 could become a world-beater.
