Aircraft profile

A fighter built around simplicity

Northrop developed the F-5 as a light, practical supersonic fighter. It was small, cheap to run and easy to fix, which is a big part of why so many air forces bought one. The later Tiger II got a bigger wing, stronger engines and a radar, and it still looks like the same little jet.

Why enthusiasts remember it

A shape that travels

From training ranges to airshows, the F-5’s slender fuselage, paired intakes, and swept wings made it one of the most recognizable jet fighters of its era. This page celebrates that story through aircraft identification, service history, and the details that reward a closer look.
