(I have recreated this thread again, since the original "reloaded" thread was lost when the forum accidentally itself.) So what is a "Kerbalized Rocket"? A kerbalized rocket is a real-life rocket/ICBM/launch vehicle recreated in KSP, without using a dedicated parts pack for the specific launch vehicle (example: recreating the Proton rocket using a handful of part add-ons, but not using the Soviet parts pack itself). For reference, check out this thread I have created way back November 2011 (post there at your own risk, thread was already inactive for almost a year now ). I recommend NovaPunch Reloaded and KW Rocketry parts pack for extras. That would be everything you need (based on my experience) if you want to use them. Feel free to share your creations! I start: StratoLaunch
Falcon 9
SLS
Atlas V
Proton Falcon Heavy (was compelled to get this thing up once more because of the kerbalized N1 )
