Realistic Delta 4 Heavy

This rocket is not autonomous, but looks really cool...

ABOUT THE CRAFT: The Delta IV Heavy (Delta 9250H) is an expendable heavy-lift launch vehicle, the largest type of the Delta IV family. It is the world's second highest-capacity launch vehicle in operation, behind SpaceX's Falcon Heavy (with its core stage expended), and closely followed by CNSA's Long March 5. It is manufactured by United Launch Alliance and was first launched in 2004.
The Delta IV Heavy consists of a central Common Booster Core (CBC), with two additional CBCs as liquid rocket boosters instead of the GEM-60 solid rocket motors used by the Delta IV Medium+ versions. At lift off, all three cores operate at full thrust, and 44 seconds later the center core throttles down to 55% to conserve fuel until booster separation. The boosters burn out at 242 seconds after launch and are separated as the core booster throttles back up to full thrust. The core burns out 86 seconds later, and the second stage completes the ascent to orbit.
The launch vehicle uses three RS-68 engines, one in the central core and one in each booster.
