Supertest: ISU-130
Here’s the summary of upcoming tier 8 Soviet premium/reward tank destroyer, ISU-130. Basically, it’s ISU-152 with SU-100Y’s gun.
Description:

Heavy SPG based on ISU-122S. It was developed in 1944 and a prototype was built in October of the same year. It was created by installing a 130mm S-26 gun, which was developed from the naval B-13 gun on the ISU-122S platform. Driving and shooting trials were conducted until June 1945. Because of the end of WW2 and the fact that the gun was inferior in penetration to 122 guns, ISU-130 was not accepted in service.
