Future Two new satellites, SXM-11 and SXM-12, were ordered from Maxar Space Systems in November 2022.
Decommissioned
Elliptical
Prior to the merger, the Sirius Satellite Radio service operated with three satellites in a highly elliptical orbit. Following the merger, the combined Sirius XM adopted XM's geostationary pattern, though Sirius's original satellites remained in service until 2016, when they were decommissioned and placed into disposal orbit.

Sirius FM-4, also built by Space Systems/Loral, was a ground spare that was never launched. It was donated to the National Air and Space Museum in October 2012, and is currently displayed at the Steven F. Udvar-Hazy Center.
