A hospital ship built around practical medical capacity

What would an ideal modern hospital ship look like?

A container ship could be rebuilt around the equivalent of multiple emergency departments, expanded critical care, diagnostics, ward space, and humanitarian-mission capacity.

The design principle is practical conversion rather than a bespoke prestige vessel. A container-ship hull supplies the volume needed for multiple emergency departments and expanded critical care. Diagnostics, general medical support, and ward space must be planned as one patient pathway rather than added as separate modules. The result can support military casualties while retaining the capacity for humanitarian and mercy missions.
