Well, based on what is written, do we think it is more likely that he is talking about a specific model of destroyer in the future that will be the most advanced in the world -- or merely saying that there will be future destroyers that are very advanced, that 055 is a stepping stone to?
I think the latter is far more likely than the former.... mostly because the title of "world's most advanced destroyer" is empty without knowing what timespan we're comparing it to and how long it will be the "most advanced," making it difficult to narrow it down to a specific future potential destroyer class.
As you mention, what 星海 wrote was in response to people's complaints about 055's VLS count at the time -- i.e.: that the primary subject of the passage is 055, and its role as a beginning for future classes to build on.
There is nothing to indicate a reference to a specific class of future destroyer; no designation, no timespan, no simple reasoning for why it deserves being called "world's most advanced" etc. Only that there will be future destroyer classes, which we have known since well before 055 was first launched.
