Local armour around a warship's vital spaces

A proposal for future warships places local armour around machinery, combat-information, and medical spaces inside the ship's subdivision. Retrofitting that protection to existing designs is considered difficult. The aim is to make damage harder to spread into essential spaces after a missile has penetrated the ship. Missiles, electronic warfare, and chaff can try to prevent the hit; internal protection addresses the consequences when those defences fail. The proposed measure would reduce the chance that local damage becomes a loss of essential operation or flotation.
