The first prototypes of the Kanonenjagdpanzer, also known as the Jagdpanzer Kanone 90mm, were produced in 1960 by the Hanomag and Henschel companies for the FRG. Production continued until 1967. A total of 770 vehicles for the Bundeswehr and 80 for the Belgian Armed Forces were built. However, in 1985 the vehicle was deemed outdated. Some of them were converted into artillery observation vehicles and others were refitted into anti-tank guided missile carriers. Some Kanonenjagdpanzer remained in service until 1990.
