Overview[]
The IS-85 or IS-1 is a Soviet heavy tank developed in 1943 from the KV-13.
Naming[]
| Name | Description |
|---|---|
| Ob. 237 | "Object" designation -- the only designation that is kept throughout. |
| IS-85 | After the initial concept of the "Iosif Stalin" (IS) tank, the caliber of the gun was used to differentiate the models. Others included the IS-122, and IS-100. The ISU series also uses the same logic. |
| IS-1 | After standardizing the IS series in the 1943/44 period, the Ob. 237 received the designation IS-1, and the Ob. 240 received IS-2. Ob. 244 and 245 received IS-3 and IS-4 respectively. |
| IS-1 | After the initial IS series were developed, only the in-service IS vehicles would keep their designations, with IS-3 and later being reused. The Ob. 237 kept its position as IS-1. |
