WASHINGTON — The Space Systems Command on Oct. 31 announced 21 launch missions have been assigned to United Launch Alliance and SpaceX as part of the National Security Space Launch (NSSL) Phase 2 contract the companies won in 2020.
These missions assigned for fiscal year 2024 mark the fifth and final year of the Phase 2 contract. Of the 21 missions, ULA received 11 and SpaceX 10. These missions are projected to launch over the next two to three years.
Over the five years of the Phase 2 contract, the Space Force will have ordered a total of 48 missions — substantially more than the 34 missions originally estimated — although only one has launched so far.
“Under our Phase 2 contract, ULA and SpaceX have been committed partners, and our combined team remains dedicated to delivery of critical assets to our warfighters as we complete this phase of the NSSL program and embark on NSSL Phase 3 starting in FY25,” said Col. Chad Melone, senior materiel leader for mission solutions at the Space Systems Command.
A total of 48 missions in Phase 2
Of the 48 missions assigned for Phase 2, only USSF-67 launched, aboard a SpaceX Falcon Heavy rocket in January 2023. ULA’s first Phase 2 launch will be USSF-51 on an Atlas 5 rocket, a mission projected for no earlier than March 2024.
SpaceX’s upcoming NSSL missions include USSF-52 (awarded in 2018 and not part of Phase 2) and USSF-124, a Missile Defense Agency mission that is part of the Phase 2 contract.
ULA’s new rocket, Vulcan Centaur, was selected by the Space Force to launch all Phase 2 missions but the vehicle has been beset by delays. Vulcan’s two certification flights are scheduled in the coming months and its first NSSL Phase 2 mission, USSF-106, would fly sometime after both certification launches are completed.
ULA originally won 60% of the Phase 2 missions and SpaceX 40%. Based on these latest assignments, ULA ended up with 54% and SpaceX with 46%.
