What makes the Mitsubishi F2 fighter aircraft technologically significant in aviation history?

The Mitsubishi F2 achieved notable technological firsts despite its limited production. It was the first production aircraft to feature an AESA radar (JAPG1), beating even the F-22 to this innovation. The Japanese also developed the AAM4B missile with the world's first AESA seeker radar in 2010. The F2 featured 25% larger wings than the F-16 it was based on, offering increased range and additional hardpoints for weapons. Though only 94 were built instead of the planned 140, these innovations showcase Japan's aerospace capabilities, with the aircraft continuing to defend Japanese airspace against Russian incursions and expected to remain in service into the 2030s.
