Hi all

Is the exterior difference between ISU-122 and ISU-152 only the gun itself?

Does this mean that you build both version from the Tamiya ISU-152 and substitute the barrel for the ISU-122 version?

Happy modeling
Ole

http://en.wikipedia.org/wiki/ISU-122

I'm no expert by any means but according to Wikipedia

Construction of the ISU-122 and ISU-152 is the same except for the gun mounting, sights and ammunition stowage. The A-19S or D-25S cannons of the ISU-122 had 18 degrees elevation angle and 30 rounds of ammunition (the ISU-152 had 20 degrees and 20 rounds respectively). The A-19S cannon was equipped with an ST-18 (СТ-18) telescopic sight and the D-25S cannon was equipped with a TSh-17 (ТШ-17) sight. Both types of sights had maximal exact targeting distance of 1.5 km (the ISU-152 could manage only 900 m). Maximum direct fire range of the A-19S or D-25S cannons was 5 km, much further than these sights' targeting abilities. For direct or indirect firing on distances over 1.5 km the gunner used the second, panoramic sight.

The crew of the ISU-122 was 5 men and their location and roles were identical to those of ISU-152 crewmen. The ISU-122S was used with either 4 or 5-man crews since the semi-automatic breech allowed for a reasonable fire rate with a crew of four; the place of the absent loader was often taken up with additional ammunition. With a five man crew (two loaders) the ISU-122S demonstrated a better fire rate than with four men.


I'm sure someone else will be able to give you more definite answers.

Cheers

Only EXTERIOR differences were the gun and manlet.

Hi Jeff and Jacques

Thank you for your answers.

This means that I could use the Tamiya ISU152 as backbone for the ISU122 and if lucky get hold of the mantel and barrel from the old Dragon ISU122/152 from someone and voila

Yep, just exterior really. I converted 2 Tamiya ISU-152's into both the ISU-122 and ISU-122S using the DML parts and alittle work here and there. They have since been put on the back burner for the time being but they were coming out fairly decently far as the conversion goes. See about getting the CMK metal barrel for the ISU-122, the A-19, if you want the turned aluminum type, otherwise I think the DML plastic barrels would work fine. Good luck.

Question - would the MiniArt 122 & 152 Ammo sets be correct for these two vehicles ?
