About this creation
"The Viper-class Sloop is a fast scout ship and the smallest Warp-capable vessel utilised by the Imperial Navy of Battlefleet Calixis." The quoted text is directly from the Warhammer 40K Wikia website.
Now that I look at the model, I am not happy with it, and think the ship could represent a different class. Still, when I build it a year ago I had this end in mind and hope you enjoy the spirit of what I tried to do. I think you should check out my other 40K ship builds for better results. The larger ships will be posted in the next day or two, so check back if you don't see them!
