Question

What would be the Pacific-war impact of long-range American minelaying submarines?

Short answer

They could create sustained disruption around Japan because the mines would remain and build up after the submarines left.

Notes

Long-range submarine minelaying could exert significant pressure on Japanese movement. Mines remain after the laying submarine is gone and can accumulate into a persistent obstacle. The effect is sustained disruption and denial rather than one decisive engagement.
