Vulcan rocket faces backlog test after military launch

ULA's Vulcan rocket successfully launched US military satellites into high orbit, marking its first national security mission. The mission, USSF-106, demonstrated the rocket's capability for complex maneuvers, with its Centaur upper stage completing the task over seven hours. This flight follows two successful test flights that led to its certification for Pentagon missions. Despite this success, concerns remain about ULA's ability to meet its substantial backlog of over 70 contracted launches, primarily for the Space Force and Amazon's Kuiper network.
