Radio relejno čvorište veze JNA Velebitska Plješevica 

Potpuno devastirano i odneseno sve sto se moglo , ali unatoc tome ovaj  vojni objektat i dalje djeluje
zapanjujuce kada se nađete u njemu . T o posebno vrijedi za podzemni dio koji nisam niti uspio proci zbog preslabe rasvjete, ;) S mobitelom nemojte niti pokusavat uci dalje od ovog sto vidite na slikama,

Pored glavne zgrade nalazi se pomocni objekat , tj garaza  i radionica s takozvanom grabom za servis vozila .

Ulaz u podzemni objekt se nalazi u glavnoj zgradi tako da se spusttie stubistem na par metara nize , Iznad vas se tad nalazi 15 metarski ventilacijski otvor , a ispred put u podzemlje.

 Jedan od izlaza iz objekta na drugoj strani brda , POstoje tri takva na određenoj udaljenosti  ali u istoj ravnini. Dalje se penjete stubistem da dođete na nivo od kuce . Razlikaj je neki 30-tak metara.

ARK Operativni centar komande vojno pomorske oblasti JNA bunker

Code-name "Object 182", is an abandoned deep underground military facility in Croatia. The official title for the facility was "Operativni centar komande vojno pomorske oblasti", which stands for "Naval region Operations command center". Basically, it was Yugoslavia's version of the American NORAD.

The facility is the second largest underground facility in Croatia, and one of the largest in former Yugoslavia. It has all the necessary equipment to house personnel for a prolonged period of time in case of wartime (built to withstand nuclear blasts and biological threats).
The facility is notoriously complex, and the included 3D animation doesn't show any levels, just the "shell" of the place. The larger "halls" shown in the animation are actually 4 story buildings built inside the mountain, that house apartments, "war rooms", generators, AC & filters, etc.... It also served as a "nerve" hub for various systems, including the Stina C and Neptun. Topside, the facility had 2 radio-relay domes, pointed towards two adjacent RRCv's- network of underground radio relay bases that are in direct line of sight and cover the whole territory of Yugoslavia. 
Radar information (from boats, planes, radar stations, etc...) and other tactical information (intelligence) was collected and grouped in this facility so that the commanders and radar operators inside could make the appropriate decision on which action to take. The facility was responsible for protecting Yugoslavia's both air and naval territory (west; south-west side).
The place is has been abandoned after the end of the independence war in Croatia and stays derelict to this day, visited only by a handful of urban explorers... and unfortunately.... scavengers.

Exploration of Top secret exJNA bunker (Radio Relay Station ) Magarčevac

Radio-relejni centar Magarčevac uz podzemni aerodrom Željava, bio je jedna od najčuvanijih tajni bivše JNA, a dokaz tome je da se i dan danas teško ili skoro nikako ne mogu naci nikakve informacije o tom objektu ukopanom 30 metara u dubinu planine a koji je služio kao komunikacijski centar i čvorište za bivšu JNA.

Podzemni aerodrom Željava (objekat 505)

Željava Airbase, situated on the border between Croatia and Bosnia and Herzegovina under Plješevica Mountain, near the city ofBihać, Bosnia, was the largest underground airport and military airbase in the former Yugoslavia, and one of the largest in Europe. The facilities are shared by the local governments of Bihać and Lika-Senj County in Croatia.


Construction of the Željava or Bihać Airbase, code-named “Objekat 505”, began in 1948 and was completed in 1968. During those two decades, SFRJ spent approximately $6 billion on its construction, three times the combined current annual military budgets of Serbia and Croatia. It was one of the largest and most expensive military construction projects in Europe.


The role of the facility was to establish, integrate, and coordinate a nationwide early warning radar network in SFRJ akin to NORAD. The complex was designed and built to sustain a direct hit from a 20-kiloton nuclear bomb, equivalent to the one dropped onNagasaki.

Strategic role

The main advantage of the base was the strategic location of its “Celopek” intercept and surveillance radar on Mount Pljesevica, at the nerve center of an advanced integrated air defense network covering the airspace and territory of Yugoslavia, and possibly further. In addition to its main roles as a protected radar installation, control center, and secure communications facility, the airbase contained underground tunnels housing two full fighter squadrons, one reconnaissance squadron, and associated maintenance facilities. The units based there were the 124.LAE (Fighter Aviation Squadron) and 125.LAE, both equipped with MiG-21bis fighter aircraft, and the 352.IAE (Reconnaissance Aviation Squadron), equipped with MiG-21R reconnaissance-fighter aircraft.
The underground tunnels ran a total length of 3.5 kilometers, and the bunker had four entrances protected by 100-ton pressurized doors, three of which were customized for use by fixed-wing aircraft. Eventually, it was hoped that the base would be re-equipped with the indigenously developed Yu Supersonik aircraft.

Underground “KLEK” complex

The underground facility was lined with semicircular concrete shields, arranged every ten meters, to cushion the impact of incoming munitions. The complex included an underground water source, power generators, crew quarters, and other strategic military facilities. It also housed a mess hall that could feed 1,000 people simultaneously, along with enough food, fuel, and arms to last 30 days without resupply. Fuel was supplied by a 20-kilometer underground pipe network that ran from a military warehouse on Pokoj Hillnear Bihać.


Topside, the facility had five runways. In the immediate vicinity of the base, there were numerous short-range mobile tracking and targeting radars, missile-equipped sites, 2K12 “Kub” (NATO: SA-6) mobile surface-to-air missile interceptor systems, motorized infantry bases, military police stations, and a hunting lodge used by civilian and military leaders on occasional leisure trips.
Access points were heavily monitored and guards authorized to fire on anyone attempting to enter without authorization. In practice, however, only special permits were required and unauthorized visitors usually turned away.


The airbase was used intensively in 1991, during the Yugoslav Wars. During its withdrawal, the Yugoslav People’s Army destroyed the runway by filling pre-built spaces (explicitly designed for the purpose) with explosives and detonating them. To prevent any possible further use of the complex by opposing forces, the Military of Serbian Krajina completed the destruction in 1992 by setting off an additional 56 tons of explosives there. The ensuing explosion was so powerful that it shook the nearby city of Bihać. Villagers claimed that smoke continued to rise from the tunnels for six months after the explosion.

Current status

Local police forces and the CPA currently use the area to train canines with actual land mines, given the extensive number of mines still in the vicinity. Because of the mines, extreme caution must be used when visiting the Željava complex. In November 2000, a Bosnian Air Force Major died from his injuries after setting off a PROM-2 anti-personnel mine while searching for mushrooms.
The toll of the destruction on base buildings and equipment is incalculable and caused great environmental damage. Potential reconstruction endeavors are limited by a lack of financial resources. An international border cuts the base area in two, and the entire area is heavily mined. The barracks in the nearby village of Ličko Petrovo Selo are operated by the Croatian Army.
Today, the base often serves as a waypoint for illegal migrants. A facility for asylum seekers was scheduled to open there in 2004 or 2005, but the idea was abandoned, and new plans were developed for it to become part of the Slunj military training grounds, and barracks from the nearby Udbina complex. This idea was dropped, however, in line with the agreement between the countries of former Yugoslavia which bans any military facility up to 15 km inside the borders.
The Bihać Municipality launched an initiative to open a local airport using the runway.

Javni izvori i pojedini vojni predstavnici bivše Jugoslavije, navode  da je
od 1950. do 1990. godine  izgrađeno 26 tajnih podzemnih vojnih objekata s atomskom  zaštitom
koji su u  biti smješteni na sljedeći način:
- Srbija - 7
- Hrvatska - 5
- Bosna i Hercegovina - 6 (navodno čak 17)
- Slovenija - 3
- Makedonija - 3
- Crna Gora - 2
Ukupna vrijednost izgradnje tih objekata trebala je biti  oko 90 milijardi američkih
dolara. Naravno, ovo su  samo nagađanja  jer prema drugim izvorima izgrađeno je  oko 50 takvih
objekata. Cijene, naravno, nisu poznate, novinari navode da bi cijena mogla biti  oko
200 milijarde dolara.
Naravno, zbog razbijanja SFRJ i nekoliko godina građanskog i vjerskog rata, većina ovih  objekata je uništena a samo malo ih je ostalo netaknuto.
