KazakhstanReported count for MiG-31 · Mig-31/Mig-31BM. Country-wide list; no individual service specified. 1 distinct count cell(s) from the same source list; shared rowspan cells counted once. Retired, wholly reserve and on-order rows are excluded; the reported count retains any explicitly mixed stock scope in the quoted row. Count column(s): quantity: 31. Origin: Soviet Union. The listed variants/roles are the scope, not an immediately deployable count. Dates are the count-cell citations' stated source period (2024), not the article revision. 2024 cited source edition. Edition or publication years do not claim an exact inventory census day.
