Why missile-era survivability differs from battleship armor

The panel begins with the missile's range and ability to correct its path, then debates whether adaptable warheads make traditional battleship armor uneconomic. One side argues that an armor-piercing missile variant could be fielded quickly; the other notes the opportunity cost of carrying specialized warheads instead of general-purpose weapons. Survivability is therefore framed as a sequence: avoid the hit, keep combat and propulsion systems working, preserve buoyancy for towing, and make abandonment possible if all else fails. Subdivision and internal protection over machinery may matter more than a continuous belt because an incoming weapon may have to cross several decks and protected spaces before disabling the ship. If planners expect a long conventional war rather than a brief nuclear exchange, the discussion suggests that localized armor could become attractive again, especially alongside emerging weapons such as railguns.
