If Littoral Combat Ship modules had worked

Would the US guided-missile frigate have adopted mission modules if the Littoral Combat Ship concept had succeeded?

Probably, because a proven module system would have been an obvious design inheritance for the next frigate.

A successful Littoral Combat Ship mission-module system would probably have influenced the next American frigate. The answer rests on the expectation that procurement organisations reuse ideas that work. StanFlex is offered as an existing modular approach for the US Navy to consider. This remains a counterfactual about a successful LCS programme, without a detailed proposal for fitting modules to a particular frigate.
