Satellites of United States of America
13,573 satellites in orbit, 12,612 operating.
The count is the catalogue’s as of Nov 12, 2026, 4:17 PM; whether a satellite is operating is as Orbinauts writes it where it has written when the satellite’s mission ended, and otherwise as Jonathan McDowell’s general catalogue believes it, licensed CC BY 4.0: GCAT
GCAT, Jonathan McDowell’s general catalogue (CC BY 4.0), credits these satellites to United States of America under the code US.
