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).

Contents

An underground hangar complex may include tunnels containing the normal elements of a military air base—fuel storage, weapon storage, rooms for maintaining the aircraft systems, a communications centre, briefing rooms, kitchen, dining rooms, sleeping areas and generators for electrical power.

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

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 Su-24 Fencer aircraft equipped with +2000 km cruises, Iran announced that it has more underground bases that will be unveiled in the future.

Israel

Eight Israeli air force F-16I Sufa fighter aircraft were damaged in the winter of early 2020 by flooding when they were improperly left inside underground hangars in a Negev desert airbase during severe flooding. [4] The Washington Post reported in 2012 based on the results FOIA requests to the US government that the US Army Corps of Engineers brought in US construction contractors to build installations in the south of Israel including underground hangars for fighter-bombers as a part of US military aid to Israel.

North Korea

There are at least twenty major airfields with underground hangars in North Korea, including Onchon air base, Kang Da Ri Airport and Sunchon Airport. [7]

Sweden

In 1941 the Swedish Air Force began building its first underground hangar at Göta Wing (F 9), located near Gothenburg in south-west Sweden, it was commissioned in 1944. [10] After World War II plans were made up for building underground hangars at every air force base that had suitable rock conditions. These ambitious building plans proved to be too expensive and were reduced to hangars at certain select air bases. [11] A second underground hangar was built in 1947 at Södertörn Wing (F 18). [10] After that plans were finalized for building underground hangars capable of surviving close hits by tactical nuclear weapons. This required that these new hangars be much deeper, with 25 to 30 meters of rock cover, and heavy-duty blast doors in concrete. [11] The Saab 37 Viggen aircraft was designed with a folding tail fin to fit into low hangars. Aeroseum, an aircraft museum open to the public in Gothenborg, is housed in the larger cold war era Underground Hangar at Säve. [12]

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. [13] 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. [14] [15] The idea of using roads as runways was later part of the design demands for the Swiss motorway network. [16] [17]

Taiwan

Chiashan Air Force Base, located in Hualien, has an extensive underground hangar system which can accommodate two hundred aircraft. [18]

Chihhang Air Base in Taitung County can accommodate eighty aircraft in underground hangars. [19]

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.

<span class="mw-page-title-main">Bas 60</span>

Bas 60 was an air base system developed and used by the Swedish Air Force during the Cold War. The system was based around defensive force dispersal of aircraft and its supporting ground operations across many krigsflygbaser in case of war, primarily as a protective measure against nuclear weapons. The purpose of the system was to make it complicated for an opponent to destroy the Swedish Air Force on the ground and thus ensure endurance for the air force in a conflict scenario. The plan was to disperse the air units so one krigsflygbas would house one squadron. This dispersion principle also applied to the individual wartime bases themselves, meaning that the various functions of an air base were spread over a large area in and around the base.

<span class="mw-page-title-main">Bas 90</span> Class of Swedish airbases

Bas 90 was an air base system used by the Swedish Air Force during the Cold War. Bas 90 was developed during the 1970s and 1980s from the existing Bas 60 system in response to the new threats and needs that had arisen since the conception of the Bas 60 system during the 1950s. Like its predecessor, the Bas 90 system was based around defensive force dispersal of aircraft across many krigsflygbaser in case of war, as well as dispersion of the air base functions within the individual bases themselves. The air units would have been dispersed so one squadron would be stationed per krigsflygbas. The system was a protective measure against nuclear weapons and airstrikes, to make it complicated for an opponent to destroy the Swedish Air Force on the ground and thus ensure endurance for the air force in a conflict scenario.
