The ÖAF gl sLKW (abbreviation for "heavy offroad truck") traces its roots to the 1973 oil price hike which resulted from the Yom Kippur war in the Middle East. Trying to provide economic stimuli to the stuttering Austrian economy, the government initiated the procurement of a new heavy offroad military truck with 10 t payload capacity.
While MAN already had developed a similar vehicle for the German Bundeswehr (the MAN "KAT"), ÖAF in Vienna used the same platform but replaced the air-cooled Deutz engine with a water-cooled 12.7-liter MAN V8 delivering 320 HP. Starting in March 1976, this truck entered military service in five variants (designated as G1 to G5). By 2005, the first "S" trucks were retired, and today only a handful of these trucks is still in active military service. Our truck is the second vehicle ever built and spent its whole active service with the army driving school ("HKS") in Baden.
