USSF-106 is a mission for the United States Space Force. The launch will deploy various payloads directly into geosynchronous orbit, including the NTS-3 (Navigation Technology Satellite 3), a demonstration navigation satellite testing a new digital signal generator that can be reprogrammed on-orbit to broadcast new signals, improve performance by avoiding and defeating interference, and adding signatures for detecting spoofing attacks.

Vulcan Centaur is a two-stage-to-orbit, heavy-lift launch vehicle under development by United Launch Alliance (ULA) since 2014. It is principally designed to meet launch demands for the U.S. government's National Security Space Launch (NSSL) program for use by the United States Space Force and U.S. intelligence agencies for national security satellite launches. It will replace both of ULA's existing launchers (Atlas V and Delta IV Heavy) in this role, as these launchers are retiring.
See DetailsUnited 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.
