Why Japan, Korea, and China build warships faster

Why can Japan, Korea, and China build destroyers or frigates faster than Europe?

They have kept yards and production lines active, while Western programs often order too slowly and change designs during construction.

Production efficiency depends on maintaining yards, placing repeat orders, and preserving a workforce that builds related ships continuously. Japan, South Korea, and China benefit from active shipbuilding infrastructure and steadier production rates. Western programs often lose time to small batches and 'tinker disease' that repeatedly alters requirements after construction begins. Faster delivery is therefore an industrial and governance outcome, not evidence that the physical act of assembling a destroyer is inherently easier in Asia.
