The SU-85 (Samokhodnaya Ustanovka 85) was a Soviet casemate-style self-propelled gun used during World War II, based on the chassis of the T-34 medium tank. Earlier Soviet self-propelled guns were meant to serve as either assault guns, such as the SU-122, or as tank destroyers; the SU-85 fell into the latter category. The designation "85" signifies the bore of the vehicle's armament, the 85 mm D-5S gun.

The SU-122 (from Samokhodnaya Ustanovka 122 mm) was a Soviet self-propelled howitzer or assault gun used during World War II. The number "122" in the designation represents the caliber of the main armament— a 122 mm M-30S howitzer. The chassis was that of the T-34.

Objective for this project:
- To create a 3-sprue 1/56 (28mm) plastic kit
- Options to build either a SU-85 tank destroyer or a SU-122 assault gun
- Hopefully will include a tank commander








NOTE: This render is already out-dated.  We have made many changes to it since the original posting a month earlier.  Can you find them out when compared with the above line drawings?


Enjoy!

They  look great  . May I recommend  the round style front fenders for the SU -85 ,the angled type are more late war ie SU 85M /100. Also spare track is needed on the front plate under the gun of the SU-85 . As the space between the tow hooks was wider than the T-34 tank , they had 7 track links instead of 5 . No room on the front of the   Su-122 for anything  :) .

The vehicle design will enable you too choose between round style or angled type front fenders for the SU-122; of course, the SU-85 will only use the round style front fenders.

For the spare tracks, we have already taken notes on the subject.  Thanks!

Ripley is right about the SU-85's spare tracks and fenders.  I'm really happy to see these vehicles in the pipeline - especially the SU-122. 

Here's my suggested re-write of the introductory blurb - this makes them both sound a bit more exciting.  The SU-122 should come first.

The SU-122 ('Samokhodnaya Ustanovka 122' - the number represents the calibre of the main armament) was a Soviet self-propelled assault gun that entered service in late 1942.  Inspired by the German Sturmgeschutz III assault gun, it was built on the proven T-34 chassis.  It was intended to provide fire support for the infantry, but the introduction of a new shaped charge anti-tank round in 1943 enabled it to deal effectively with German armour at short ranges.     

The SU-85 ('Samokhodnaya Ustanovka 85') was a Soviet self-propelled gun, also based on the T-34 chassis.  It was the result of a crash program in 1943 to develop a tank destroyer that could deal with heavy German tanks like the Tiger I, which was largely invulnerable to the standard 76.2mm Soviet tank gun.  The SU-85's main armament was a modified 85mm anti-aircraft gun.  As it was intended to provide long-range anti-tank support, no machine-gun was fitted.  It first saw action in 1943, and proved to be a popular weapon.

Thanks Pinky for the rewrite.  The original write-up is again wikipedia material (with minor modifications)... haha!

Nice to have a choice in fender styles , but the Su -122 never had angled style fenders , IRC it was out of production by that time . In fact some factories never did implement the angle fender or change from dish wheels   even in  post war production of T-34 /85 & SU-100.

Ripley, in that case, might save us two extra parts...  ;)

Just a quick update on our SU project:

- We have revamped the top front hull assembly on both the SU-85 and SU-122 so that they are much easier to get attached to the hull body.
- The SU-85 gun assembly had also been reworked so that it will be comparable to the real gun in terms of elevation and rotation.
- The hatches (edited, thanks ripley) on both tanks had also been modified and make them sturdier when they are open.
- We have decided to re-tool the optional oil drums on the original "common" T-34/76 and T-34/85 sprue.  The T-34/76 front hull machine gun also benefit on this change.
- Have sent the file to 3D prototyping, and hopefully will see some samples soon!

;)

 Just to set things straight , the SU-122 and 85 really didn't have Commander hatches . The Commander in each , sat in the right front corner of the vehicle. The SU-85 had a movable periscope and 2 fixed ones in a bulge on the roof . The SU-122 only had a movable scope as it was a indirect fire weapon , which sat back from the front line like the artillery piece it was based on .  The square hatches on both vehicles are for  crew access and resupply of ammo . The SU-100 did have a Commanders hatch , it being the same round cupola used on the T-34/85 tank .

I think Rubicon was just referring to the hatches generally.  Open hatches are one of the vulnerable points of wargaming models - along with headlights and MG barrels...

Really looking forward to this kit.

Sorry , just a little OCD when it comes to identifying tank parts . So many kits have things mislabeled . Really can't wait for this lit though . I thought my Russians were good with 8 T-34 tanks , but now I'm going to have to rethink my combat force . And kit bash more tank riders  ::) . Maybe when Rubicon gets their figures perfected they could release sets of seated tank riders from the major players of WW2 . Sort of like BA figure sprues , 5 or 6 seated bodies , assorted heads , arms and weapons .

We totally agree, we had spend a lot of time trying to get the right part names, but sometimes is quite difficult for us because of language translation issues... still we tried our best!

Soviet tank riders had ALWAYS on our mind... something that we would like to do it right!  Probably 5 to 6 riders in various poses with different weapons in summer uniform.  Will make that happen in 2016!

Finally had the time to get the SU SPG (SU-85 & SU-122) 3D prototypes done:























Comment anyone?

Nice Kit. The details looks good. What about some tools on the chasis or where there usualy none?
