The Saurer 4K 4FA is an Austrian armoured personnel carrier with caterpillar tracks. It was later replaced by the Steyr 4K 7FA G 127. It went into production in 1961. [1]

The Steyr-Daimler-Puch 4K 7FA G 127 is an up-armoured version of the earlier Saurer 4K 4FA armoured personnel carrier, which was developed to meet the requirements of the Austrian Army.

When Steyr Daimler-Puch bought the line in 1970, they produced a similar but updated 4K 7FA series that contained many of the internal components of the SK 105 light tank/tank destroyer. The resulting design is a viable, versatile, and widely recognized production line for armored personnel carriers for the Austrian Army and some global allies.

The Austrian 4K 4FA APC was built by Steyr with sloped armor, low profile and all-steel welded construction in the 1960s. It was replaced by the 7FA.

The Steyr 4F 7FA G127 armoured personnel carrier is a continuation of the development of the older 4K 4FA G1/G2. It has improved armour protection, a more powerful power unit and an upgraded transmission.

In 1956, Osterreichische Saurer-Werke of Vienna (which was taken over by Steyr-Daimler-Puch AG in 1970) started development of a full-tracked armoured personnel carrier. The first prototype, the 3K 3H, was completed in 1958 and the second, the 4K 3H, the following year. They are both powered by a Saurer 3H 200 hp diesel engine.

Steyr also designed a more heavily-armed version of the 4K 7FA, called the 4K 7FA MICV 30/1. This version has a turret with a 30mm Rarden autocannon, a coaxial machinegun, and a commander’s cupola with a pintle mount.
