Right after occupying Yugoslavia, Germans commandeered the factory on 17 April 1941. The complex was heavily bombed during the massive Allied Easter bombing of Belgrade in April 1944. The facilities of Ikarus were almost completely destroyed during the war, but the factory was rebuilt. In 1946 Zmaj and Rogožarski were merged with the Ikarus, after previously being nationalized. In 1954 the company began producing buses and, starting from 1960, the production of aircraft was being shut down and relocated to the SOKO factory in Mostar, Bosnia and Herzegovina. Production of the aircraft was completely discontinued in 1962 and, until that date, Ikarus produced a total of 475 planes after the war. The facilities were completely demolished and the area is today occupied by the residential buildings, stretching between the Hotel Jugoslavija on the east, and "Palmira Toljatija" Street (roughly blocks 9-A and 11-C. divided between the municipalities of Zemun and New Belgrade). The engineers and the design bureau were transferred to the Aeronautical Technical Institute in the Belgrade's suburb of Žarkovo. The company was ultimately renamed to Ikarbus.
