Due to their specific construction of these airfields - which included taxi-ways leading right out of Hardened Aircraft Shelters (HAS) and laid diagonally to the runways - they became known as "Trapezoids" or "Yugos".

In order to build these, the Yugoslavs used equipment and construction techniques identical to that use in underground oil-storage depots, additionally concealing the extension and the true purpose of the whole project.

The underground facilities were all hardened to withstand a direct hit by a tactical nuclear bomb, buried up to 50 meters below the ground and consisted of the main aircraft "hangar" (consisting of two floors in several cases, connected by 40ts hydraulic lifts), connected with operations, maintenance, and logistical facilities via a net of underground corridors.
