The Northrop F-5 Freedom Fighter / Tiger II is a lightweight supersonic fighter family developed by Northrop for export customers and low operating cost. The later F-5E/F Tiger II added improved power, radar, and weapons fit, and the type saw documented combat service from Vietnam through Yemen, Africa, and Iran-related conflicts.
The F-5 started as a compact, low-cost fighter for export customers and evolved into the more capable F-5E/F Tiger II, which added more power, radar, and improved weapons fit.
