Ha, this looks very much like a moc I once made called the 'black hole buster' It was a huge ship, but it was in minifig scale. It only held two minifigs. The rest of the space was taken by enormous power sources and force fields that were needed to keep the ship together while travelling through black hole singularities. It was basically a very bulky fighter, able to jump in and out of pieces of space and do some serious damage. The fighters of the opposite camp wouldn't be able to follow it through the black hole it jumped back in. I've been wondering if I should post it on here, since I do have some pics of it.
