This is, of course, the precursor to the flying winnebago in Space Balls...
LOL! Not the prettiest thing I agree. But it has ten heavy turbolasers and twenty ion cannons (a great deal of them replace the ion cannons with twenty laser cannons). Even without its shields it can take severe puishment because of its incredibly dense structure.
This picture has to be a joke. Whoever designed it clearly had a terminal case of, uh, "cruiser envy."
