The Delta IV Heavy I really like the design of the Delta IV Heavy, so I decided to make one in KSP. It has no problems getting to a Kerbosynchronous orbit. I have also used it to get to Minmus and the Mün. I have a slideshow of me getting to a Kerbosynchronous orbit with it here: http://imgur.com/a/WvLB3. One thing I really like about it is that once you're at a Kerbosynchronous apoapsis, you can do a quick retrograde burn, and jettison the satellite. You can then use the satellite's H and N RCS to get back into a Kerbosynchronous orbit. This will help prevent debris cluttering Kerbin. EDIT: Wow, just used it to get to the Mün, then to Minmus, then back to Kerbin. Never had a ship that could do that before.

Just tell me what you'd like, and I'll get to it as soon as I can.
