Production of the second prototype of the aircraft no. 60002 stopped at the factory Ikarus, and all documentation was submitted Soko factory in Mostar.

The second prototype of the Soko 522 no.60002 completed in late 1954 in Sokol factory.

These two air bases represented the first level of defense. The second level of defense were also airports with underground galleries and the conditions for protection against a nuclear attack. Such were underground galleries in Podgorica, Mostar, and Split. The third level of defense was reinforced concrete shelters for aircraft and people. All airports had them. Each plane had its own reinforced concrete shelter. The Yugoslav underground project represents the labyri
