Current plans call for the Centaur V to be eventually upgraded with Integrated Vehicle Fluids technology to become the Advanced Cryogenic Evolved Stage (ACES). Vulcan is intended to undergo the human-rating certification process to allow the launch of crew.
The Vulcan booster will have a 5.4 m (18 ft) outer diameter to support the methane fuel burned by the Blue Origin BE-4 engines. ...
