Austrian air defense

Austrian air defense

Austrian air defence is undertaken by the integration of civilian and military radar systems under the authority of the Austrian Air Force.


In the past the control of the Austrian airspace took place by means of a single radarstation located on the summit of Kolomannsberg. This station was completed by 2 dimensional radardata from civil airports and some mobile Bendix "AN/TPS-1" searchradars.

Today the Austrian airspace control and its air defence is based on the Goldhaube system. "Goldhaube is named after a traditional cap worn by the Austrian girls" (see link).

Goldhaube is a combined military airspace commanding, controlling and alerting system that uses modern radar equipment to protect Austria’s airspace against any kind of intruders. The most important Goldhaube units are located on the summit of Kolomannsberg, Koralpe and Buschberg.

All systems are connected together in the Austrian "Einsatzzentrale/Basisraum" (EZ/B). This is the commandcentre and government crisesbunker, located 300m inside a mountain near the village of Heukareck in the vicinity of St. Johann and Salzburg. The bunker, known by insiders as "der Berg" (the mountain), was built in 1977-1982 and houses overall military and civilian leadership in case of war or crisis.

Although this system is already more than 20 years operational it is still being under extensive development. These upgrades assure that Goldhaube stays fully operational in the next decades.


By building a new radar in the south of Austria, by integration of the civil airport authorities in the military chain of command, by building an air operations centre and a backup centre, by totally renewing the Kolomannsberg radar station and by incorporating a datalink and communications network, a state of the art airspace control and air defence system would be at the disposal of the Austrian authorities.

*1964-1970. Building and operational readiness of the fixed radarstation Kolomannsberg
*1970-1983 Planning and activation of the Goldhaube radarsystem including the buying of an Italian "Selenia (nowadays Alenia) RAT-31S & MRCS-403" radar system, planning and building of an "Einsatzzentrale/Basisraum (government crisisbunker"), building of the fixed radarstations Speikkogel and Steinmandl and the airtraffic control center Schnirchgasse Wien (Vienna).

tart of Goldhaube project

In 1973 a combined civil/military project "Flugverkehrskontrolle - Luftraumüberwachung" (airtraffic and airspace control) had been inaugurated to integrate both services in a combined one. As a direct consequence in 1975 the "Stab Luftraum Beobachtungs System" (aircontrol staff) had been activated in the Austrian air force.

From a military point of view the need of the actual target altitude as well as an extended view exceeding the Austrian boundaries was absolutely necessary. After the evaluation authorities confirmed the green light for a 3 dimensional radar system in which distance, heading and altitude were incorporated in a single radar picture.

The Austrian military staff decided to buy the Italian [ Selenia RAT-31S / MRCS-403] instead of the American "Westinghouse AN/TPS-43E" system.

Although the new Selenia system technology suffered development problems in the mid 1980’s, resulting in a delay of operational activation, the decision to buy the system has been proven to be the right one. Twenty years after operational activation of the first RAT-31S, Austria’s air control system is comparable with the very best air control systems and still meets the highest of standards.

*1997-2000 Ordering and activation of new EF2000 Typhoon Eurofighter interceptors and ordering a new Long-Range Radar (RAT-31DL) system extension.
*2000-2007 Decommissioning of 24 Saab Draken fighter interceptors, ordering of extra Eurofighters, decommissioning of F-5E Tiger II aircraft, ordering IRIS-T missiles for the Eurofighters and operational readiness of RAT-31DL on Kolomannsberg.
