--Fictional Backstory--
In 2028, after multiple successful launches of Starship and Neutron, Blue Origin is faced with an issue: they can't keep up with their competitor's launch cadence. To increase New Glenn's production rate, they stop selling BE-4 engines to ULA, effectively ceasing the Vulcan program. In a massive stroke of luck, the US government decides that spy satellite launches cannot happen on privately developed launchers. As a result, they sponsored the development of a successor: the Vulcan II.
The upper stage traces its roots to the Delta Cryogenic Upper Stage, but with a key difference: it uses methalox fuel, and a full flow stage combustion engine, based on the Raptor.
The first stage has been made to be as simple and cheap as possible. It uses a kerolox engine, a development of the old russian RD-180, used on Atlas V launchers.
A fun little quirk, a heritage of the Delta II are the three air-lit boosters. They ignite as soon as the other six are separate and support the first stage during the first part of its flight.
It looks like i've put more effort into the backstory than in the actual booster :)
