Delta III

Delta III is a retired expendable launch system in the Delta rocket family. It was manufactured and operated by Boeing. Delta III only launched 3 times with 2 failures and 1 partial failure. After this poor performance, the Delta III was retired in favor of Delta IV. The larger GEM-46 Solid Rocket Motors were subsequently used on Delta II making it Delta II Heavy. The vehicle only operated out of Space Launch Complex 17B at Cape Canaveral Air Force Station. 

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

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

Also Don’t forget to download the flags for Delta III in the "Files" section.
