In the near-term, ULA will switch back to launching its soon-to-retire Atlas V rocket, the Vulcan rocket's predecessor. The company has 13 more Atlas Vs in its inventory, most of them sold to Amazon and Boeing to launch Kuiper Internet satellites and Starliner crew missions to the International Space Station.

The 202-foot (61-meter) Vulcan Centaur has made two successful flights thus far. The rocket's first flight in January 2024 saw Vulcan launch Astrobotic's Peregrine lunar lander toward the moon — only for the lander to suffer an anomaly and fall back to Earth through no fault of the rocket.
