The Delta IV Heavy (Delta 9250H) is an expendable rocket, the largest type of the Delta IV family. It was first launched in 2004.
It is similar to the Medium+ (5,2), except that it uses two additional CBCs instead of using GEMs. These are strap-on boosters which are separated earlier in the flight than the center CBC. The Delta IV Heavy also features a stretched 5-meter composite payload fairing. An aluminum trisector fairing derived from the Titan IV fairing is also available. The first launch in 2004 was a test launch only. Its first payload was the DSP-23 satellite.
I modeled everything in 3ds Max, and the rendering in Maxwell and V-Ray. I used five lighting passes and composited them in Photoshop. I wanted to go for that 1960's style painterly look for this image.
