Comparing: ISU-130 vs. Kanonenjagdpanzer

This heavy SPG on the basis of the ISU-122S was developed in 1944, with a prototype built in October. The 130-mm S-26 gun, based on the B-13 naval gun, was mounted on the ISU-122S. The vehicle underwent automotive and firing trials by 1945, but penetration characteristics were inferior to those of the 122-mm guns, and the war was drawing to a close, so the vehicle never entered service.

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 However, in 1985 the vehicle was deemed outdated.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.
