SES-20 & SES-21 are a pair of C-band communication satellites built by Boeing, using the highly efficient all-electric propulsion BSS-702SP satellite bus. These satellites will enable SES to clear 280MHz of mid-band spectrum for 5G use while seamlessly migrating SES’s existing C-band customers and ensuring the continued delivery of digital television to nearly 120 million American TV homes and other critical data...

Alternate mission URLs consolidate to this canonical launch record so exact mission timing, status, media, and source context stay on one page.
Use these internal paths to move from this exact launch record into the provider, vehicle, launch-site, schedule, and mission-family pages that own broader context.
This launch currently has no dedicated mission-family hub, so provider, vehicle, site, and canonical record links are the primary internal paths.
Some high-demand launch records carry specialized search intent. These profiles explain what can be verified from the published record without filling gaps that upstream sources have not published.
Payload and orbit evidence is shown from published launch, payload, mission, and source-link records so the page can answer spacecraft, customer, orbit, provider, and schedule intent.
Key structured fields for this launch record are grouped here so the page answers mission, payload, orbit, provider, source, and timing questions before the deeper tracking and media sections.
This record is preserved as historical launch context. The page emphasizes what was launched, the vehicle and pad involved, published outcome/status fields, linked programs, and source records instead of treating the mission like an upcoming countdown.

United Launch Alliance (ULA) is a joint venture of Lockheed Martin Space Systems and Boeing Defense, Space & Security. ULA was formed in December 2006 by combining the teams at these companies which provide spacecraft launch services to the government of the United States. ULA launches from both coasts of the US. They launch their Atlas V vehicle from LC-41 in Cape Canaveral and LC-3E at Vandeberg. Their Delta IV launches from LC-37 at Cape Canaveral and LC-6 at Vandenberg.
