About this model
Vostok Blok E is one of the 203 3D models Space Radar made itself: a rocket stage, built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh.
Shape built from published dimensions and pictures; details simplified. It has 3,776 triangles in a 38 kB glTF file, and is 4.8 m across at full scale.
It is part of the map’s library; no object on the live map is drawn with it today.

The Russian cutaway drawing 'R-7 vostok.jpg' (Commons, public domain, read 2026-10-28): 'Блок III ступени 2980' = block III 2.98 m; Astronautix 'Vostok 8K72K' (read 2026-10-28): block E 2.56 m across and 2.84 m long; ru.wikipedia 'Восток (ракета-носитель)' (read 2026-10-28): the single-chamber RD-0109 with four steering nozzles. McDowell's GCAT (CC BY 4.0, read 2026-11-07): the catalogued 'Vostok-2M Stage 3' (bus Blok-E): mass 1 440 kg, length 3.8 m, diameter 2.6 m. THE SOURCES DISAGREE on the hull's length (2.98, 2.84 and, with the engine, 3.8 m): the hull is built 3.1 m between its skirt and its cap as the drawing's joints give them, and the bell and adapter cone are drawn outside that, 4.83 m overall. The hull's bands, hatches, ports and every fitting, the bell's length and the adapter cone are READ OFF THE PHOTOGRAPHS of the museum copies and are ILLUSTRATIVE in the metre. NOT CITED: the wall, the tanks inside. (read 2026-11-07)
How it was made
Built in code from published dimensions and photographs, with no image-to-3D generator and no one else’s mesh. 3D model: built by Space Radar from published dimensions; compared with museum photographs of the R-7 at VDNKh and Kaluga (CC BY, CC BY-SA) and a Russian cutaway drawing (public domain).
The full record
built by this project in code (tools/vostok-builder/blok_e_stage.py, which calls r7.build_blok_e(): the same part the Vostok launcher of release 1.5.0 is made of); no agency or museum 3D model of Vostok exists under a free licence (read 2026-10-29, see the row `r7-8k72k`); no image-to-3D model was used and no published mesh
Where the map uses it. catalogue name SL-3 R/B (klass rocket): the spent third stage of the Vostok launcher (Blok E, 8K72K; 11 in the CelesTrak copy of 2026-11-05), as it stays in orbit: the hull with its RD-0109 bell and four verniers and the payload adapter, WITHOUT the truss (it stays with the core) and without the shroud. It is `blok-e`, the part of `r7-8k72k` (release 1.5.0), taken out on its own; forge #60
Licence note. The shape is this project's, under this repository's licence, built from published numbers (facts). Every picture it was compared with is listed under references; each was only looked at, none was traced, copied or projected, and the share-alike ones (CC BY-SA) are credited all the same.
