I know TF10000 is going to be expensive but new engine development is more expensive. We should focus on the engine we have at hand and build more stuff on top of it instead.Currently, Baykar is considering its options on twin engine Kızılelma. Baykar might shelve twin engine Kızılelma in favor of a single 20000 lbf class( ~12000lbf dry, ~20000lbf wet thrust) engine. That is why they are willing to develop a 20000 lbs engine. Baykar is aiming for 10000-12000kg MTOW and supercruise capability and more than double the current payload capacity.
