To be perfectly honest... most of these wedge shaped ships aren't aerodynamic at all. An aerodynamic object is flat under, round over and have no sudden cuts over the stern, as that would be a powerful aerobreaker. If dropped into an atmosphere unpowered, the Cobra would fall stern first, as would most of the wedged shapes. So, actually, most of the ships are designed to fly in space and only the brute force of their engines make them flyable in atmospheres, with at best, hulls that at least allow air to pass.
The T9 is actually the most wing shaped ship. The Viper is a rather good design, though I would fill in the gaps around the engines for air flight. The Clipper is nicely shaped, but I'm afraid actual air resistance would tear its "wings" off, due to turbulence in the open spaces. If you glassed its struts in, it might actually generate some lift.
All these ships are designed for space flight only, more or less. Shapes support stress and center of gravitation, not air.
