The first test of KGK from a UAV is done at a low altitude so a 50+km range for a high altitude release is not surprising.
KGK-LR as of now is a SAGE project it is not officially requested from the Turkish Armed Forces or SSB. We don't know from which direction the wind will blow. It seems like the Kuzgun project has the priority. But you should know that warhead of Kuzgun is small and you cant destroy hard targets like tunnels or caves or reinforced aircraft shelters(though I'm sure it can fly through a hangar door
) with Kuzgun. Kuzgun is a high-tech asset that is developed to hunt other mobile high-tech assets by swarming them at stand-off ranges. Laser guidance for KGK is in the works and it is a contracted project. Laser KGK will be able to engage mobile targets. KGK for Mk84 is also a contracted work. Lastly, a wing kit for light torpedoes is being developed by SAGE. This is also most likely an official request which comes from the navy.
