UM 1/72 SU-85M Self-propelled Gun

By Kent Kirkpatrick

Overview

This first self-propelled gun mount using the T34 chassis was the SU-85. With the corresponding upgrade of the T34 with the same 85mm main gun it became unnecessary and limited in its production. This SPG would soon be replaced by the more powerful SU-100. Its primary role was anti-tank support for tank and infantry units. It suffered due to its limited range of gun depression. The SU-85 was withdrawn from service in September 1944. It went on to serve other countries in other conflicts.

The Kit

UM's standard box art is very well done as a reference with a color plate on the back when you get ready to paint and apply decals. The color plate on the back of the box art contains a Humbrol color reference to use when painting this model. This SU-85M kit contains a three-part sprue of photo-etch, 2 vinyl sprues containing 22 parts, and 5 styrene sprues containing 142 parts. The styrene parts molded in a green drab color with no sinkholes, injector pin indentations or flash residue. UM seems to use a softer styrene for their kits. This is good in that small parts may bend but not break when mishandled. All parts appear to be well defined and in scale. The SU-85M kit shares 4 sprues with their SU-122 kit, mainly the rear deck, lower hull and suspension parts. The black vinyl parts include two tow cables and 20 rubber tires. Somewhat puzzling is the rubber rim detail which looks somewhat like an automobile tire tread. Having the rim separate from the road wheel allows the builder to be more creative with this model especially if you wanted to emulate a burned-out vehicle. One notable difference with this kit is instead of the dish-type road wheels you get the spoke-type and they are very nice in detail. There are front and back rims with 2 rubber rims to complete one road wheel. Separate suspension arms allow you to articulate the vehicle on smooth or rough surface. The length and link tracks are finely detailed on both sides. The lower hull is made up of 9 parts. The upper hull is divided into 2 sub-assemblies, one for the main gun housing and the other for the engine deck. Both are very well detailed. The nine-piece 85mm gun housing sprue appears to have a rough texture to it similar to rolled steel. The eighteen-piece engine deck has the same level of detail. The photo-etched two-man saw and engine deck screen enhance the level of detail. The photo-etched bow machine gun ring is not used. Do not throw it away, save it for another model perhaps. There are 4 external fuel tanks that are made up of 4 parts each. Building these will be the most time-consuming part of the upper hull assembly. A suggestion would be to drill out the engine exhausts. I suggest using a round dental bit to open up the headlight assembly (part 67A) for MV lenses. That would really enhance the appearance of this model. The nicely illustrated kit instructions are tri-lingual (Ukrainian, German and English) and use symbols to assist you in assembly. These symbols tend to make some steps look somewhat confusing but are effectual. Knowing someone who reads Ukrainian would help. Which brings me to the decal sheet. The quality is excellent in that the decal film is very thin and the printing of the markings are fine. There are markings for two vehicles from different battlefronts. Eastern Prussian Front (Winter 1945) and Belo-Russian Front (Spring 1945). Unfortunately, there is no unit information associated with the decals. Positioning of the decals does not appear to be difficult as they are all located on the angular surface of the main gun housing.

Conclusion

UM's venture in producing the T34 variants is a welcome addition to small-scale Russian armor subjects. With the T34 chassis in the bag now UM is doing the SU self-propelled gun tank series. As with their other kits they do not lack for quality and are reasonably priced. You will not be disappointed with purchasing a UM product.

I would like to thank Squadron Mail Order for the review kit.
