The features of the various prototypes were then combined into the final design. After that another set of six prototypes were built over the next two years still by Hanomag and Henschel.

A second round of 6 prototypes this time built just by Hanomag and Henschel were constructed between 19.

The first prototypes of the Kanonenjagdpanzer were built in 1960 by Hanomag and Henschel for West Germany and by MOWAG for Switzerland, based on the experience of the Wehrmacht in the Second World War, the Kanonenjagdpanzer being a development of the Jagdpanzer IV. The Kanonenjagdpanzer is also known as the Jagdpanzer ("tank destroyer"), Kanone 90mm ("90mm Gun") or Kanonenjagdpanzer 4–5. Its design was very similar to that of the World War II Jagdpanzer IV. The Kanonenjagdpanzer ( KanJPz) was a West German Cold War tank destroyer.
