Which modern warship would be most suitable for use as a prison ship?
Short answerAn LPD would be the least unsuitable choice, but modern warships generally lack the secure internal divisions and support facilities a prison requires.
NotesAn LPD would be the least unsuitable modern warship because it offers more internal volume than most combatants. That still does not make it a good prison ship. Secure detention needs controlled zones within zones, reliable separation between groups, and the accommodation and support services required for a captive population. A warship can isolate ordinary watertight sections, but its internal layout and hotel systems are designed for a trained crew rather than prisoners and guards.
