Avionics and sensors NCSIST is developing an airborne AESA radar for the T-5 Brave Eagle but private Taiwanese firm Tron Future Tech has also bid their gallium nitride based AESA for the program. In 2019 it was announced that Pyras Technology would supply the radar and communications antennas for the platform.
More than 55% of its components are made in Taiwan.
