I want to recreate real rockets inside a space sim game called KSP, but for that I need to know what sizes those rockets have ( diameter, height, etc ), not just in general, but each of their stages specifically.

For example, I found on the official ULA website that the fairing of the rocket Delta V is 5 m in diameter and 15.992 m in height, but I can't find anything about the first or second stage.

Anyone know where I could find this info? I only need sizes.


To clarify, I want stage height and diameters, for example, how tall is the first stage of the Atlas V or Delta IV? I have searched on Wiki but it only gives me the total height of the rockets in question.


I looked again and I did find the sizes for the stages of Atlas V on Wiki, but not Delta IV. Wikipedia is inconsistent. What a shocker. Any place with consistent info?

There's no single complete-and-consistent site. Wikipedia is a pretty good resource in my experience (and you should contribute to it when you find it deficient), but here are a few others:

Spaceflight101 has a good library of current launchers, with quite a bit of information about each of their stages, but no historical data.

Astronautix aka Encyclopedia Astronautica has a wealth of historical information, but isn't very well organized or consistent in the data provided.

Gunter's Space Page has more information on individual flights, but less specification info on the launchers.

(Are you using RSS/RO, or stock KSP?)
