Delta IV Heavy
This, again, aesthetic replica was used to launch the interplanetary standard stage and probes of varying sizes and purposes to the outer and innermost planets of the Kerbol system.
This stage was built using the KW Rocketry and Hexagonal Struts mods, purely cause it looked cool. Powered by the Hex Struts proprietary nuclear engine, it could manage all planetary systems with a little fuel to spare.
