Hungary used its Ju 86s to bomb Slovakian airfields and defensive positions during the Slovak–Hungarian War in March 1939. From June 1941, Hungary's Ju 86s began to be replaced by Italian Caproni Ca.135 bombers. An independent bomber squadron, equipped with a mix of Ju 86s and Ca 135s was deployed in support of the Hungarian Gyorshadtest (or Fast Corps) during the German-led invasion of the Soviet Union, but the Ju 86 was withdrawn from front line service by Hungary during 1942.
