A United Launch Alliance (ULA) Vulcan rocket will deliver national security spacecraft directly to geosynchronous orbit for the U.S. Space Force Space Systems Command on the USSF-87 mission. Liftoff will occur from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida. Launch ...
USSF-87 will launch two identical Geosynchronous Space Situational Awareness Program (GSSAP) satellites GSSAP-7 and GSSAP-8 directly to a near-geosynchronous orbit approximately 36,000 km above the equator. Data from the GSSAP will uniquely contribute to timely and accurate orbital predictions, further enabling space flight safety including satellite collision avoidance.

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.

"You absolutely have to have a plan to compete with SpaceX on price."
A familiar anomaly encountered during Vulcan's launch of USSF-87 raises significant concerns for the vehicle’s immediate future.
United Launch Alliance’s (ULA’s) new Vulcan rocket delivered U.S. Space Force satellites to geosynchronous orbit today despite a “significant performance anomaly” on one of the Solid Rocket Boosters. This was […]
The anomaly appears similar to the nozzle burn through seen during the launch of the second certification flight of a Vulcan rocket.
The USSF-87 will be the second national security flight for United Launch Alliance’s Vulcan rocket and the fourth flight of this type of rocket to date. Liftoff from pad 41 at Cape Canaveral Space Force Station is scheduled for 3:30 a.m. E…
