gotta give credit to "Chinese speed". apparently it takes 4 years to build a burke. this takes maybe 2 max?
No it certainly does not take 4 years to build a Arleigh Burke
over the last 35 years between them both Iron Works and Ingall's shipyard have launched 75 units taking into account pauses between the flights restart programs which in some cases is 5 years
but even then thats over 2 units per year between two yards which is roughly 1 per year for each yard for over 3.5 decades
Type 055 maybe higher tonnage but we have JNCX and DL launching 8 units in roughly 3 years
thats 2.66 units per year but to make it fair we included the restart programs in the Arleigh Burke program so actually 8 units over 7 years which is 1 per year between two yards or 2 years per yard
so actually both Iron Works and Ingall's shipyard have had a higher rate for much longer period
so we need to see JNCX + DL do sustained numbers for prolonged periods of times over decades
however there is a catch because JNCX and DL also make Type 052D/L DDG
I guess if you add that into account then yes JNCX and DL would seem to be appear to have higher production capacity than Iron Works and Ingall's and can certainly outstrip their American counterparts in peacetime production
