ULA: Most Vulcan Systems Have Atlas or Delta Heritage

In a press conference today leading up to the maiden launch of the ULA Vulcan in the early hours of Monday morning, ULA Vice President of Government and Commercial Programs Gary Wentz stated that the vast majority of the new rocket is either flight-proven or a variant of flight-proven hardware. He said that “the only hardware that hasn’t flown prior to this flight is the BE-4 engine. All the other or variants thereof have flown on Atlas or Delta flights, missions for other customers.”
