The Serbian Ratno Vazduhoplovstvo i Protivvazduhoplovna Odbrana (Air Force and Air Defence - RV i PVO) will retain MiG-21 fighters in service until 2025 and buy Mi-35M attack and three Mi-17V5 transport helicopters by the end of the year, Brig Gen Zeljko Bilic, commander of the RV i PVO's 204th Air Force Brigade, told Serbian national TV station RTS1 on 2 August.
The RV i PVO's commander, Maj Gen Dusko Zarkovic, told the Politika newspaper on 27 July, "We still have some MiG-21 aircraft and also qualified and experienced pilots and technical personnel. We believe that at this point it would not be justified to 'administratively' remove this aircraft from operational use," adding, "further investments in the type are unprofitable".
