Delta IV

Delta IV is an active expendable launch system in the Delta rocket family. It was formerly operated by Boeing, and is now operated by United Launch Alliance (ULA). Delta IV is built in 5 variants: Delta IV Medium; Delta IV Medium+ (4,2), (5,2), (5,4); Delta IV Heavy. The first digit in the bracket stands for second stage diameter in meters and the other digit stands for number of SRBs. The vehicle operates out of Space Launch Complex 37 at Cape Canaveral Air Force Station and Space Launch Complex 6 at Vandenberg Air Force Base. There was also Delta IV Small _ variant considered with Delta-K second stage that is used by Delta II.

I recommend turning on "Advanced tweakables" in KSP settings.

To download each variant of Delta IV, go to the "Files" section.
