Indonesia was the 1st export customer of the Korean built KT-1 and initially received 17 units (serialled LD-0101 through LD-0117) and assigned to Training Squadron 102 in Yogyakarta. LD-0105 still wears the big black serials instead of "TNI-AU" letters later applied. By now, all TNI-AU KT-1's are assigned to the Jupiter Aerobatic Team, and have been re-serialled to LL-01XX (LD-0105 shown here became LL-0105). As of December 2021, at least two additional KT-1's are about to join the fleet to make up for the few aircraft lost during accidents. They will become LL-0118 and LL-0119.
