I see. Thank you for the clarification.The drone in the last picture was an earlier design iteration of the "KUS-X" stealth UCAV program based on the KAORI-X ("Stingray-X") demonstrator. KAI lost the bid to KAL (Korean Airlines), so there's only this official government funded project ongoing.
Korean Airline also presented a smaller reduced RCS-drone "Loyal Wingman" at DX 2022: KUS-LW

KAL's future vision is that KUS-LWs will fulfill different tasks in a drone squad (based on swarm AI): models with recon radar, others with EW systems, escorts with air-to-air missiles, ground attack models will fly missions in team with bigger KUS-FC drones or KF-21 as MUM-T.
This somewhat funny PC-gamelike animation shows the future drone squad concept against North Korean Mig-29s (hahaha! guess they didn't want to use Chinese J-20s) and enemy ground targets.
