Avia B-534 in Slovak Service
With the partition of Czechoslovalia on 14 March 1939, Slovakia inherited 71 Avia B-534 biplane fighters. Two squadrons participated alongside Luftwaffe units in the invasion of Poland in September 1939. They were later deployed to Ukraine in 1941 during the invasion of the USSR. In 1942, one squadron was returned to Slovakia for anti-partisan operations. By 1943, obsolescence and a lack of spare parts relegated them to training roles.
During the National Slovak Uprising of September-October 1944, a B-534 shot down a Hungarian Junkers Ju 52, the last confirmed aerial victory of a biplane fighter.
