An underground hangar is a type of hangar for military aircraft, usually dug into the side of a mountain for protection. It is bigger and more protected than a hardened aircraft shelter (HAS).

An underground hangar complex may include tunnels containing the normal elements of a

Countries that have used underground hangars include Albania, China, Italy, North Korea, Norway, Sweden, Switzerland, Taiwan, Yugoslavia, Iran, Taiwan, Vietnam, South Africa and Pakistan.

By country

Iran

In 2023, Iran unveiled a large underground base called "Eagle 44": in this base, Iran's upgraded F-4 Phantom fighters were present under Shahid Doran. Also, pictures and replicas of Su 35 were seen in that base. This base, where Iranian drones are also present, is probably somewhere in the south of Iran. While broadcasting a video of another base, on the other side of which 24 Fenser planes equipped with +2000 km cruises, Iran announced that it has more underground bases that will be unveiled in the future.

Six Flugzeugkaverne (aircraft caverns), each with space for 30 or more aircraft, were constructed for the Swiss Air Force. One at Meiringen Air Base has been expanded to operate F/A-18 Hornet aircraft.[7] Originally, the plan for the aircraft hangar (German Kavernenflugplatz) included the possibility of launching combat aircraft from the mountain air base. High costs and technical difficulties prevented these plans from being realised.[8][9] The idea of using roads as runways was later part of the design demands for the Swiss motorway network.[10][11]

Taiwan

Chiashan Air Force Base, located in Hualien, has an extensive underground hangar system which can accommodate two hundred aircraft.[12]

Chihhang Air Base in Taitung County can accommodate eighty aircraft in underground hangars.[13]

Former Yugoslavia

The "Objekat" series of military installations can be found in secluded but strategically important areas within the former Yugoslavia, and the construction of these military bases were initialized by the SFRJ's defence ministry.

During the Yugoslav Wars, most of these bases were used by the Serbs in certain operations, but due to circumstances imposed by the Croat forces, they were destroyed and later rendered useless for military use.

Nowadays, they are popular for urban exploration, however it is risky due to the chances of anti-personnel landmines being located in unexplored areas. However, some were spared the destruction due to other circumstances where the Serbs did not control these installations. An example of some that are still in use to this day is the D-0 Armijska Ratna Komanda nuclear bunker in Konjic; the latter was turned into an art complex, but is still owned by the Ministry of Defence of Bosnia and Herzegovina.
