The helicopter fleet includes Agusta-Bell (AB) 204s (mainly used for medical evacuation), AB-206s (training and liaison), and AB-212s (used by air-mobile troops and for light transport). 28 French-made Alouette IIIs are available for search-and-rescue tasks, including high mountain operations. The 12 Bell OH-58 Kiowa, a scout helicopter, is mounted with a rapid-firing machine gun, but the air force lacks a true attack helicopter. Most of the helicopters, except the 24 AB-212s, are becoming obsolete (see table 16, Appendix). After the 1999 Galtür Avalanche, it became apparent that the Austrian Air Force's helicopter complement were too few in numbers and too limited in design. Therefore, 9 US-built UH-60 Blackhawk helicopters were purchased, to be used for transportation during disasters.
