Foreign frigate construction for the US Navy

What might follow from a US move toward the Finnish model of foreign frigate construction?

Buying a design for US construction leaves many choices, while overseas construction is likely limited to Japanese or South Korean yards with spare capacity.

Purchasing a foreign design for construction in American yards leaves many suppliers in contention. Buying complete ships overseas narrows the field because few countries have available yard capacity, leaving Japan and South Korea as the main options. Japanese sales experience is judged stronger at present, making the Mogami family a plausible result even though South Korea also offers capable designs. The outcome depends as much on available production capacity as on the quality of the design.
