Vostok-2M (8A92M) Launch Vehicle
Vostok-2M (8A92M) was a three-stage Soviet orbital launch vehicle in the R-7 lineage, used from 1964 through 1991. Developed as a specialized successor to Vostok-2, it placed Meteor weather, Tselina-D signals-intelligence, Resurs Earth-observation, Interkosmos, and Indian IRS spacecraft into high-inclination and Sun-synchronous orbits.

- Notes
- Exact three-stage Vostok-2M stack: four RD-107 booster engines, one RD-108 core engine, and one RD-0109 Block E engine. Vostok-2M lower-stage production suffixes evolved during its long service life; no narrower 8D74K/8D75K or later suffix is asserted without a canonical variant record.
