The K45C is the best air fighter in the known galaxy but that isn't stopping the Clones beginning the development of an even better third generation. The as yet unnamed variant is planned to enter production in 2130, the main issue being whether the required engine technology can be developed in time.
Centrepiece of the new variant will be a hybrid engine similar to that used in the K58 COIN aircraft, this combined a turbofan and an electric ducted fan for acoustic and infrared stealth. However the K58 can only fly at low speed for a limited time in electric mode. The hybrid engines in the K45 will need to provide enough power for "high subsonic" speeds for at least half an hour. The Clone state aircraft manufacturer CAC has admitted this will be a tough ask but work has now begun.
The third generation K45 is also expected to be optionally manned and have a number of other sensor and system updates.
