The Advanced Cryogenic Evolved Stage (ACES) is a proposed liquid oxygen/liquid hydrogen upper-stage rocket for use on the Vulcan space launch vehicle designed by the U.S. company United Launch Alliance (ULA). The ACES concept is currently intended to improve the on-orbit lifespan of current upper stages, enabling a variety of applications. In 2015, ULA announced conceptual plans to transition the Vulcan rocket to the ACES second stage, also referred to as Centaur Heavy, after approximately 2024. Vulcan will initially launch with the Centaur V upper stage.
