Partially as a result of its impressive maneuverability, as well as some operators continuing to maintain a preference for the established biplane configuration over the incoming generation of monoplane fighters that would soon prove to outperform them, the B-534 stayed in production for considerable time (1933-1939). During the late 1930s, Czechoslovakia sought to expand production of the type in response to German claims over the Sudetenland (the western border area of Czechoslovakia). Large numbers of the type saw combat with multiple nations during the course of the Second World War. While relatively ineffective in combat during the later stages of war due to its obsolescence, the type formed a sizeable proportion of several country's military aviation components.
