On 12 September 1945 the Military Aviation Academy in Belgrade was established to train future pilots. The development of the JRV was further helped in late 1945 with the creation of the Aeronautical Union of Yugoslavia (Vazduhoplovnni Savez Jugoslavije - VSJ). This comprised six aeronautical unions - one for each constituent republic - with the joint aim of promoting sport flying and aeronautical techniques amongst the nation's young people. In June 1947 the first VSJ flying school at Borongaj (near Zagreb) started training pupils.
