It actually does several of the CVN-99 rear bridge pieces. They provide some of the lifting force that keeps the ship at just above the density of air, while other parts with equally wacky physics help stabilize the flight, provide additional lift, and prevent the uncontrollable rapid ascent seen when using ships made entirely from the CVN-99 parts.
