How big is an F-5?
Smaller than you think. Pick something to stand beside the Tiger II, drawn from above at the same scale.
Silhouettes are simplified original drawings scaled to published length and wingspan. F-5E figures from Pima Air & Space Museum, F-16 figures from the U.S. Air Force fact sheet. The bus is a standard 40-foot transit bus, the court a regulation 94-by-50-foot NBA court, and the person 6 feet tall.
Now that you know how small it is, read why that mattered in the F-5 as an adversary, or paint your own.
Why small was the point
The F-5 was kept small on purpose. Northrop wanted a supersonic fighter that smaller air forces could afford to buy, fly and fix, and less airplane meant less fuel and fewer parts to keep running. You can read how that idea shaped the jet in the F-5 design story.
Small also made it hard to see, which is one reason the U.S. Navy still flies F-5s as adversaries to play the part of enemy fighters in training.
