Notoriously the smallest fighter jet aircraft (pure fighter, not derived from trainer aircraft), and the aircraft is being more notorious since coincidental name similarity to that three-wheeler car in BeamNG..

Haederne HF-28 Fighting Pigeon

The Haederne HF-28 Fighting Pigeon is the one of smallest lightweight fighter for everyone since Haederne Aircraft need to make a lightweight fighter jet. At the time, Haederne Aircraft want to make an F-5A/F-5E replacement, also at the same time, Haederne Aircraft want to make the 4.5 gen-level for everyone, so for cost-cutting, the aircraft prototype ended to be Folland Gnat level dimensions.. but at least the aircraft has HiMAT-level of maneuverability since the design even capable for air supremacy and light ground attack missions, though sacrificing aircraft stability.
