The Delta IV Medium+ (4,2) which is the most flown variant of the Delta IV Family, is very similar to the Delta IV Medium rocket. Both versions utilize the 4-meter variant of the DCSS. Their differences can be explained simplest as the DIVM+ (4,2) having two strap-on GEM-60 SRBs. Before retiring in 2019, the rocket was able to acquire 15 launches under its belt.

The Vizzy used for flight is a modified version of GoldenShadowGS's Orbital Maneuver Suite that allows for more user-friendly use.
