Chinese destroyer development appears to be moving towards a common core design, compared here with the platform approach used for Volvo and Ford car ranges. That design can be stretched or shortened for different hull sizes. Similar and interchangeable onboard systems offer economies of scale. Different quantities of those systems then equip the hulls for different duties.

Shared systems could support several destroyer sizes
A common design and interchangeable systems could offer production economies while different hull sizes serve different duties.
