Space Marines vs Star Wars

Okay my younger brother and I are in an argument And I need the dementions of a typical Space Marine Battle Barge. So I can put his silly death star argument to rest. As well If anyone knows of anything bigger then a battle barge that would be kicken.

from what I've been able to gather in the last few minutes is that a battlebarge is about 8km long, while the Death Star (in all its glorious pieces) is about the size of a small moon. Looking up the dimensions revealed it to be around 150km in diameter. To think a 12.5m long, single man fighter could destroy it.... Good luck doing that with a battle barge!

Death Star would annihilate a Battle Barge.

However given how terminators match up vs storm troopers, a teleport in terminator assault squad could probably waltz around the death star destroying it from within. Only possible opposition being Darth Vader.

Bah! Throw a psyker at him! Let's see how he deals with the Warp! His mind is so screwed up already he would be toast! Or just bring a psychic hood or whatever they are ( I don't play space marines so I don't know) and Vader would be useless!

I guess also if we take Vader into the equation we have to include an equivalent space marine character.

Someone Like Vulkan.... Or a BA Dread-Librarian
