Vostok-2 (8A92) Launch Vehicle
Vostok-2 (8A92) was a three-stage Soviet orbital launch vehicle in the R-7 lineage, used from 1962 through 1967 to launch Zenit-2 reconnaissance spacecraft. It combined the R-7 core and four strap-on boosters with a Blok E third stage. The configuration made 45 launch attempts before Zenit-2 missions continued on later R-7-derived variants.

- Notes
- Exact Vostok-2 three-stage R-7-derived stack: four RD-107 booster engines, one RD-108 core engine, and one improved RD-0109 Block E engine. The canonical model records intentionally do not claim narrower 8D74/8D75 production subvariants for the lower stages.
