Their idea was a 14,000 ton sized escort cruiser with a stealthy hull design similar to the Zumwalt and a 23,000 ton BMD cruiser with conventional hull since such an air defense ship would need to have its radar on most of the time negating advantages of a stealthy hull. PLAN go for a similar force layout in the future with a fully stealthy(radar, acoustic and thermal) Type 055 successor as an escort "large destroyer" along with a similarly stealthy 9-10kt general purpose destroyer and the 20kt+ CG in a brand new class of warships for the PLAN.
