With a lot of research still to be done, we're not gonna see Vietnamese MiG-21 UAVs anytime soon but so far, research has been carried out on how to have the drone automatically land properly. Converting these old interceptors into drones could benefit the Vietnam People's Air Defense-Air Force by providing a target large enough to conduct air defense exercises with the S-300 high altitude air defense missile system along with being used for attack purposes.

Although all Vietnamese MiG-21s were retired by 2010 & grounded, most are still in storage within hangers across the country. It's going to be very interesting watching progress made as the years go by.
