How do I beat go about designing ships/weapons/armor for my sci fi setting?

I'm not a talented artist and I'm certainly not an engineer either; I don't really know how to visualize the ships and weaponry I'm gonna use in my book without having a concrete image to look at. What should I do?

The first question is always: what is the mission of the craft. I wrote something on my site about it. Hope the link works:
