The F-45AEC (A Enhanced Capabilities) upgrade has begun of the 250 oldest F-45As in service with the HCSAF. The main part of the upgrade will be replacing the radar with the improved version fitted to later blocks of the F-45A (with some additional software updates). The undercarriage is also being strengthened on the planes to improve their rough field performance.
The aircraft will also be refurbished to zero-hour the airframes again.
