Built from 1948-'68 at a cost of $6 billion USD, the abandoned underground Željava Air Base (Objekt 505 / Klek) was once the largest underground airport in all of Europe. The tunnels had a total length of 3.5 km (2.2 mi) & the bunker section had four entrances protected by 100-ton pressurized doors, three of which were customized for use by fixed-wing aircraft. Although it was designed to take a direct hit from a 20 kiloton nuclear bomb (Nagasaki equivalent), it ended up being destroyed intentionally by retreating JNA forces in 1992.
