Northrop developed the F-5 as a light, practical supersonic fighter. Its compact size, twin engines, and straightforward design helped it serve with air forces across the globe. The later Tiger II brought a larger wing, more powerful engines, and improved avionics while keeping the family’s unmistakable silhouette.
