This ship is called the Whitefang and while I'm not entirely clear on the practical properties of it being shaped like a dragon, it is undoubtedly incredibly cool.
Apparently there's a whole backstory to this but I think the key thing to take away is that they're a clan of space ninjas and their spaceships are shaped like dragons.
Which makes this one of the coolest LEGO builds ever. Brilliant design work by BobDeQuatre.
