Comparing: ISU-130 vs. 8,8 cm Pak 43 Jagdtiger

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.

In 1945, the production order for the Jagdtiger was increased, and the supply of compatible guns became insufficient. As a result, approximately 20 vehicles were equipped with the 8,8 cm PaK 43 L/71 gun.
