By the end of the W.W.II units of the NOVJ (the National Liberation Army of Yugoslavia) captured eight planes of this type, and in 1947 further 14 planes, license produced after the war in Czechoslovakia under designation Mráz K-65 Čáp. Storks were in an inventory of the YAF until late 1957, when remained planes (Storchs and Čáps) were handed over to the VSJ (the national Aeronautical Association of Yugoslavia), where the last was withdrawn from use in 1960.
