Originally planned as the Valhalla Class Battleship, I quickly lost control over this project and the style it was going.
I went from trying to highlight the fantasy theme in the build from literally doing whatever I felt like... and this is the result.





The Plan B is packed with anything you could ask for - with the exception of hangar bays - to rain destruction onto anything you could think of. It has a reverse-engineered railgun from the valkyrie class and a couple of seriously scary missile turrets as well as howitzers and smaller point defenses.
Most of the ship is armored with black armor plating.

There is a large opening on the belly of the ship that allows objects to be transported into and out of the ship.
In case you prefer some tanks, they're also some in the storage bay, next to colorful boxes, yaaay!

We certainly hope no one will need the medical bay, but there is one, too.

• The entire build is 1159 blocks long (including the fire)
  
• It is 401 blocks wide
  
• and 118 blocks tall
  
• I used 2,296,948 blocks to build it - according to mcedit
  

I never got around to completely finish the interior. The build process was stopped due to the delay of the 1.9 version of the game. I then decided to rather start another project to build from scratch while waiting for 1.9 to officially release. However, this new project now requires my complete attention and the Plan B will be released in the state it is currently in.

The entire build is supposed to be viewed in this texture pack (beta)
