Why can a hospital ship not carry a powerful ECM suite if it has no conventional weapons?
Short answerBecause electronic countermeasures can be used offensively, making a strong suite inconsistent with the ship's protected noncombatant status.
NotesElectronic countermeasures are not automatically passive protection. A strong suite can interfere with opposing sensors and communications beyond the immediate self-defense of the hospital ship. That offensive potential complicates the vessel's claim to special protected status under naval law. The answer reinforces the earlier distinction between a protected hospital ship and an armed casualty-receiving warship.
