This is based off of the USS Constellation from the Star Trek episode The Doomsday Machine. This was made from a schematic save of the USS Enterprise project which can be found here.http://www.planetminecraft.com/project/tos-uss-enterprise/. It contains most of the damage detail seen in the remastered version of the episode, plus a little more. It is another great addition to the family of Star Trek Starships. Great for a survival or arcade game map.
