Duh! Got my wires crossed between 054 and 054A.
PLAN should just decomm the 054s or give it to the CG to be honest especially now with 054Bs coming online.
TBF, while the 054s are only capable of self-defense with their HHQ-10s and AK-630s (hence requiring them to be closely attached to major surface combatants of the PLAN with certain levels of/substantial levels of fleet-defense capabilities i.e. 054As, 054Bs, 052Cs, 052Ds and 055s for greater degree of protection), they can still perform their primary duties (ASW) on the high seas quite well, especially after they underwent their MLU in recent years.
Therefore, I do believe that the duo can still serve with the PLAN for quite a while.
