Integrated electric propulsion as a survivability system

Integrated electric propulsion separates power generation from the propulsion motors, allowing self-contained generating units to be distributed and isolated around a hull. American ships and other systems from the 1910s show that designers were already moving towards this arrangement. It reduces the need for long shafts passing through bulkheads and makes it less likely that one hit disables every source of power. Machinery can be divided by protective boundaries and maintained in separate groups instead of being concentrated in one vulnerable chain. Continued electrical supply also supports damage control because main power lets pumps work more effectively than limited auxiliary systems. The episode asks how capital ships, cruisers, and smaller warships before the Second World War might have survived if comparable electrical arrangements had matured earlier.
