But Hall saw solid fuels not only as a way to improve launch times or survivability, but part of a radical plan to greatly reduce the cost of ICBMs so that thousands could be built. He envisioned a future where ICBMs were the primary weapon of the US, not in the supporting role of "last ditch backup" as the Air Force saw them at the time. This would require huge deployments, which would not be possible with existing weapons due to their high cost and operational manpower requirements. A solid fuel design would be simpler to build, and easier to maintain.
