- Notes
- One documented S5.35 main engine for the first-generation Soyuz 7K-OK spacecraft. The separate backup-engine arrangement is preserved in the source-backed description without inventing a second exact engine identity; this spacecraft installation excludes the Soyuz launch vehicle and the separate KTDU-35 integrated-system row.
