The T-90S/T-90SA tank page covers the export branch of Russia's T-90 main battle tank family, centered on the T-90S marketed by Rosoboronexport and the T-90SA designation seen in export service. Azerbaijan fielded T-90S-family tanks in the 2020 Nagorno-Karabakh fighting, while Russian T-90S losses have also been visually documented in Ukraine; the record keeps subvariant labels conservative where sources identify only T-90S.
Azerbaijani T-90S/T-90SA-family tanks were fielded in the 2020 Nagorno-Karabakh fighting; Oryx's visual-loss list records Azerbaijani T-90S tanks destroyed, damaged, and damaged-and-captured.
Russian forces fielded T-90S tanks in the 2014 Russia-Ukraine War; Oryx's visual-loss list identifies Russian T-90S tanks destroyed, abandoned, and captured in Ukraine.
Role detailsThis entry treats T-90S/T-90SA as the export-family branch and links the later T-90M as adjacent family context rather than folding the Proryv modernization into this page.
| Variant | Configuration | Designation notes |
|---|---|---|
| T-90SKA | Export command configuration | Army Recognition identifies T-90SKA alongside T-90SA tanks in Algerian service, giving the page a distinct same-export-family designation without relabeling the current T-90S/T-90SA entry. Sources: Russian T-90SA main battle tanks are the backbone of Algerian army |
 | Modernized Russian T-90 family member | The later T-90M Proryv branch has its own catalog page and is linked here to keep export T-90S/T-90SA coverage distinct from the Russian modernization record. Sources: T-90M Model 2017 Proryv-3 MBT |
Army Recognition describes first Russian-made T-90SA and T-90SKA deliveries to Algeria between 2006 and 2008 under a large armored-vehicle deal.

The T-90S/T-90SA family is easiest to read by separating export specifications from conflict-use evidence and later Russian modernization records.
| Scope | What the sources support | How this page handles it |
|---|---|---|
| T-90S export baseline | Rosoboronexport lists the export T-90S with a three-person crew, 125 mm gun, guided-weapon capability, explosive reactive armor, and diesel tracked mobility. | The specifications use the export datasheet as the baseline instead of mixing in later T-90M details. |
| T-90SA designation | Secondary reporting identifies T-90SA and T-90SKA tanks in Algerian service. | The page includes T-90SA as an export-family designation but does not relabel Azerbaijani loss evidence beyond T-90S where the source uses that term. |
| Combat evidence | Oryx loss lists identify Azerbaijani T-90S losses in Nagorno-Karabakh and Russian T-90S losses in Ukraine. | Conflict-use rows are limited to those directly documented T-90S-family appearances. |
| Adjacent T-90M record | The catalog has a separate T-90M page for the Proryv modernization and its 2014 Russia-Ukraine War evidence. | T-90M appears only as a linked adjacent family member so readers can distinguish export and modernized branches. |
