Profile of the Volcano—Centaur rocket

Vulkan-Centaur rocket profile for the website Elegantdesignbureau.com . Correction: Only the heavy (6 boosters, best second stage performance) version of Vulcan will use the RL-10C-X - other versions will use the RL-10C1-1, which has a specific impulse specified. The RL-10C-X ISP will be slightly higher due to the nozzle extension.
