The I-400's fuel capacity made its operating base less dependent on proximity to the target. Singapore could have supplied a recurring trans-Pacific raid cycle because it held fuel that Japan itself increasingly lacked. Such a deployment would still require ammunition and aircraft stores to reach the base reliably. Extreme platform range can redistribute a logistical problem rather than eliminate it.

Exceptional endurance opened the possibility of basing the boats near secure fuel stocks at Singapore while sending them all the way to the American coast.
