The pictures will give you the visuals but, the whys are not there. I made it out of purple wool (watch out for fire!) because the ships have a "purple" hue to them in halo. The other color on there is grey wool, even though it looks green. The ship at its longest, it is 244 blocks long, and at its widest, 96 blocks wide. This thing has taken me forever to make, but i have to admit that i used mcedit (just to make sure both sides of the ship are symmetrical).

I would use this ship say for a world spawn or an admin "castle". Feel free to to use it but please i beg you give me some credit, and a pm saying thankyou and what server you used it on.

Credit also goes to my friends who helped me do this.
