Well, it certainly means that at this point HP is building 054As as fast as Bath built OHPs.Check post 521 by Mao, there is another 054A in the dry dock nearing completion after 571 finished sea trial.
P.S. Huangpu has taken on average around 12 months to launch a 054A, and another 6 months to commission it, so basically, it takes 18 months to commission a 054A, for all the comparable ships, it's a rate only ever achieved by Bath Iron works when constructing OHP class frigates. So, may be we can say that Huangpu is as productive as Baths Iron works.
Beyond that, I don't believe we can speculate. Bath has also been churning out the Burkes and will build the Zumwalts.
