Yugoslavia
By 6 April 1941, the VVKJ had been almost completely mobilised, and consisted of four air brigades with more than 423 aircraft of Yugoslav, German, Italian, French, Czech and British design, including 107 modern fighter aircraft, and 100 modern medium bombers. Other than a small number of locally made Rogožarski IK-3 fighters, almost all the modern aircraft available to the VVKJ were of German, Italian or British design for which limited spares and munitions were available

The Yugoslav aviation industry was quickly harnessed by the RLM and absorbed by major German producers. During June, Ikarus AD became part of WNF as its Werk VII. Under new rulers, it manufactured tail units, rudders and horizontal stabilizers for late models of the Bf 109. As part of diversification of the German aircraft industry, in Slovenia several factories were established and others switched their production programme to support the war effort. These included VDM Luftfahrtwerke Steiermark in Tezno, near Maribor (propellersand parts for DB 605 engines), KIG-Aβling in Jesenice
