All of these are very good as an exercise of ships designs.
My main objection (if I may) to the ships of Shippy2013, is about the ASROC armed variant. I believe that placing the launcher behind the Type909 radar is a very bad idea, especially when thinking about the exhaust flames from the missiles when fired. Also the high energy from the radar itself may cause problems with the quite delicate electronics of the stored missiles as well as launcher itself.
