Smaller wartime cargo ships with electric pod drives

What should a modern Liberty-ship-style wartime cargo vessel look like?

Use smaller, faster, crane-equipped ships with integrated electric drive and standardized propulsion pods for maneuverability and maintainability.

Very large merchant ships make sense on secure, established peacetime routes where ports and protection can support them. Contested logistics instead favours smaller, somewhat faster hulls, dispersing cargo across more targets and improving access to damaged or secondary ports. Built-in cranes would let the ships unload where shore equipment is unavailable. Integrated electric propulsion with multiple pods would add manoeuvrability and station-keeping for transfers to smaller craft. Standardized pods could be exchanged and repaired through a common maintenance pipeline, although the panel prefers dry-dock replacement to working on high-power electrical connections underwater.
