I am waiting for the twin-engine versions of both KE and ANKA. Those will be the real deal.
I agree with
@TR_123456 about his comment on the KE being a joke with the current engines.
KE need TF6000 at least. But definitely TF10000 to come to fruition.
Anka-3 too needs TF6000 to perform as a 5th generation stealth plane. It may even benefit from using TF10000 if heavier take off loads are going to be present.
Using twin engines in KE will make it more potent and increase its agility further with a higher top speed. It will also allow a bigger plane to be built with more payload carrying capacity without having to detract from performance. It will also allow a better supersonic flight capability.
For Anka-3 the twin engines will only help with increasing payload capacity whilst enlarging the plane. Due to its flying-wing design, Anka-3 is really not structurally suitable for supersonic flight.
But once furnished with those engines, these two planes will open totally new avenues for our airforce.
