Dispersed plants protect operational endurance

State-directed construction could place synthetic plants in narrow valleys, underground sites, or many dispersed nodes that were difficult to eliminate from the air. Surviving capacity would protect more than a simple fuel total because high-quality lubricants determine how hard and how reliably engines can be run. A modest increase in domestic fuel production could also loosen the operational timetable imposed by dwindling reserves. Aircraft availability and other engine-intensive systems might improve even without a large change in total oil supply. Even then, Japan would remain at a massive disadvantage, and the outcome of the Pacific War would not change.
