I think 40 km is already the range when it is fired from an UAV iirc.I wonder what range would KUZGUN-KY reach if it was to be launched off AKINCI. I say 55-60+ km with estimations from UAV-122.
But note that KUZGUN-KY has different flight profiles which change the range. 40 or 50 km range is likely with a ballistic path and the less talked about 20 km is with a hard manuevering one.
