## 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 public US Navy art and published numbers (public domain sources).

built by this project in code (the private tool model-from-images: assemble.py, from a yaml of primitives), from the cited dimensions and the pictures under `references`; no image-to-3D model was used, and no published mesh (NASA's 3D Resources has none of this craft and no agency model of it was found on 2026-10-27). ONLY PUBLIC, OFFICIALLY RELEASED PICTURES AND NUMBERS WERE USED: nothing beyond what the US Air Force, Space Force, Navy or the maker has released is drawn, and where a page does not say (the inside of a sensor, a payload's layout, the size of a part) the part is a plain closed shape or is left out, and the row says which.

## Dimensions

- Span: 28 m
- Bus width: 4.3 m
- Bus height: 7.9 m
- Reflectors: 14 × 5.4 m

Source: Naval Technology's project page, https://www.naval-technology.com/projects/mobile-user-objective-system-muos/, read 2026-10-27: 'The MUOS module has a wingspan of 92ft, bus width of 14ft and bus height of 26ft.' (28.0 m, 4.3 m, 7.9 m); 'The module's antenna diameter is 46ft'. Harris's press release (aeroweb-fr.net copy of the 2012 release), read 2026-10-27: 'a 14-meter diameter' reflector 'for multiple-beam operation' and a 5.4-meter one 'for legacy mission operations', both 'fixed to the satellite by precision booms'. Lockheed Martin (news.lockheedmartin.com, 2014-01-13, via search): 16 UHF beams from a multi-beam assembly; A2100 bus. Shapes, the ring of antenna stubs on the top, two wings of two panels, the long boom and the two gold reflectors are read off the Navy's released art (Commons: 'MUOS new.jpg', 'MUOS.jpg', public domain). NO PAGE GIVES THE REFLECTORS' DISTANCE FROM THE BODY, a panel's size or the exact tilt of a reflector: those are OURS (a reflector about 0.7 diameters off its feed); the body is drawn as an eight-sided prism whose corners are the cited 4.3 m.
