The SU-122 development story was particularly nuanced. The development path which ultimately resulted in the SU-122 began with a series of turreted T-34 based tank destroyer designs that did not progress beyond project stage.
The first SU-122 was not built on a Soviet chassis at all, the early 122-SG being the mating of the 122mm M-30S howitzer with captured German StuG III and Pz.Kpfw. III chassis, with a small number of conversions being undertaken and delivered to the Red Army.
The concept behind the first indigenous T-34 based SG-122M design also envisaged the re-arming of combat damaged T-34 tank chassis.
There are only two existing examples of the SU-122, of which one is nearly in original condition. That vehicle is lavishly illustrated in this book, including its original, unrestored interior.
