Tank Destroyer Cuirassier
Cuirassier, Army History Museum .

The Kürassier is a tank destroyer with a weighing tower made in Austria . It is also used as a light tank or a reconnaissance tank. In 1967 the then Saurerwerke (later Steyr Daimler Puch ) manufactured a prototype in the Vienna plant, and in 1971 five pre-series vehicles followed. The armed forces ordered a total of 150 tank destroyers of this type, which have been gradually decommissioned, sold or made available to museums since the turn of the millennium.


The Saurer infantry fighting vehicle , which was already in use in the Austrian armed forces , was modified and the turret and cannon were placed on top. The chassis consists of five rollers and three support rollers on each side, rear-wheel drive, rubber-padded chain, torsion bar suspension. The engine is located at the rear on the left - the supposedly modified Spz has the engine in the front section, where the drive takes place.

The 105 mm cannon comes from the French manufacturer GIAT .

The weighing tower also comes from France and is also used in the French AMX-13 tank . The cuirassier is similar to the AMX-50 . It is a modified FL 12/44 and equipped with a so-called apex mount , which considerably simplifies the installation of an automatic loader, but at the same time leads to a relatively high silhouette. The otherwise big disadvantage of the low elevation range (−6 ° to + 13 °) is hardly significant with a tank destroyer. To achieve this, a high rate of fire of up to twelve rounds per minute is achieved; the drums only have to be reloaded from the outside after twelve shots.

The commander's cupola is on the left side of the turret, the driver sits in the front left, and the gunner is on the right in the turret.

The cuirassier has been in service with the Austrian Armed Forces since 1972.

The armored recovery vehicle Greif A1 ("4KH7FA SB20") and the pioneer tank SK 105 PiPz ("4KH7FA-AVE") also inherited the nickname with the engine, so that one can speak of a common platform.
