this is counterfactual because the 055 and 052D both have AESA radars while AB outside of very limited Flight III ships are all PESA. Your facts are incorrect - there has been no such focus. Thus the conclusion is also wrong.2. In recent years, it is the USA which has focused on expensive and very high-performance AESA radars due to incoming supersonic/hypersonic missiles. In comparison, Chinese destroyers do not face large numbers of supersonic/hypersonic missiles. So I suspect that contributes to the much lower cost of Chinese destroyers.
Chinese shipyards only make measly profit from warships. They are more after the prestige, the warship is more of an advertisement for them. They make enough profit from making commercial ships, at least for CSSC shipyards.
US shipyards used by US defense industry no longer make commercial ships. The international shipbuilding market for the US is at this point, practically non existent, and the only commercial ships are made to satisfy the Jones Act. For this reason, they have to put enough profit margins on the warships to be able to finance the continued existence of the shipyard. The Chinese shipyard has no need for such. The US continues to dole out warship contracts as a subsidy to keep these shipyards alive.
As for the AESA costs, the Chinese AESAs are capable of dealing with supersonic, tactical ballistic and even antisatellite (according to CCTV-7 videos), so they are also high performance. The reasons why they are cheaper is because they have been mass producing them much longer --- since the first Type 052C --- and has made many many destroyers ever since. The US has only begun to make theirs, so they face higher initial costs.

Does anyone aware that new 52DL modules are spotted at Dalian a few days ago?
