Steyr-Daimler-Puch Spezialfahrzeug AG & Co KG developed the SK 105 light tank/tank destroyer to meet the Austrian Army's operational requirement for a mobile anti-tank vehicle. The first pre-production vehicles were completed in 1971 and since then almost 700 have been built for home and export markets.

The SK 105 shares many common automotive components with the Steyr-Daimler-Puch full-tracked armoured personnel carrier. It is fitted with a two-person oscillating turret armed with a 105mm rifled gun. The 105mm gun is fed by two revolver-type magazines, each of which holds six rounds. The empty cartridge cases are ejected outside of the turret bustle at the rear.

The SK 105 has been constantly improved; the latest production version features a computerised fire-control system with day/night sights for the commander and gunner and a new fully-automatic transmission.

Various options for the SK 105 include a Steyr-Daimler-Puch upgrade package to bring older vehicles up to the latest production standard, NBC (nuclear, biological, chemical) protection system and different types of night vision equipment including image intensification or thermal.
