The Ratno vazduhoplovstvo i protivvazdušna odbrana (RV i PVO), or Air Force and Air Defence, was a major branch of the Yugoslav People's Army (JNA) from 1959 until 1992. At its peak, it was one of Europe's largest air forces, utilizing a mix of Soviet-supplied aircraft (MiG-21s) and domestically produced planes (Soko G-4 Super Galeb, J-22 Orao).
