The Ambrosini SAI.403 Dardo ("Dart") was a light fighter aircraft built in Italy during World War II.

SAI.403 Dardo was a considerably refined version of the SAI.207, designed during the delays in that type's development.

Apart from the fighter's superlative performance, its all-wood construction was attractive at a time when Italy was facing a shortage of strategic materials.

Japanese pilots then stationed in Germany were also given a chance to fly the aircraft, with the result that it was ordered into production by both Heinkel and Mitsubishi.
