The key message of that leak(coupled with the post about lengthening not constituting enough of a change for a new letter) was basically that PLAN needs the line rolling.
A good way to keep the line rolling is not to stop the line from rolling in the first place, which is what PLAN allowed to occur several years back now. If 054A does "resume" in much the same configuration as it ended, it is difficult to avoid the conclusion that PLAN has likely experienced a development failure with 054B akin to that which led USN to first end and then resume Burke IIA production.
That is to say, the most plausible explanation of what we have seen these past few years is that there was an 054B program intended to follow-on from 054A shortly after 2020. That program ran into problems. Perhaps those problems were technical, perhaps doctrinal, perhaps both. A re-tooled 054B development program is now underway, and significant numbers of additional 054As have been ordered to compensate both for the 054Bs that were originally expected to already be under construction and for those originally expected to be constructed over the next few years, and as insurance against further potential problems with the 054B project.
