Great Eastern as a global torpedo-boat depot

How would Great Eastern be fitted for naval duty?

As a global depot and torpedo-boat carrier, using her size for cranes, small craft, workshops, and supplies rather than heavy combat.

Rather than turn the huge liner into a conventional fighting ship, the proposal uses its volume and range to support small craft around the world. Great Eastern's upper works would carry cranes, boat stowage, and a substantial group of torpedo boats. Her interior could hold the workshops, ammunition, fuel, and stores needed to keep those flotillas operating away from established bases. The ship becomes a mobile naval base whose value comes from sustainment and reach rather than heavy combat armament.
