The first prototypes of the Kanonenjagdpanzer were produced in 1960 by the Hanomag and Henschel companies for the FRG. Mass production continued until 1967. A total of 770 vehicles for the Bundeswehr and 80 for the Belgian Armed Forces were built. In 1983, the vehicle was deemed outdated. According to engineers, some of them could be equipped with 105 mm guns, but the vehicles were eventually converted into artillery observation vehicles or anti-tank guided missile carriers. The Kanonenjagdpanzer (also known as Jagdpanzer Kanone 90mm) remained in service in citizen military forces until 1990.
