Why ships rely on compartmentation and spall protection

The panel contrasts small punctures in aircraft fuel tanks with ship-scale blast damage and explains how subdivision and internal armor protect vital spaces.

Notes

Self-sealing aircraft tanks address holes measured in projectile calibers, while damage to a ship is often measured in feet or meters. Ships therefore divide fuel among multiple tanks so that one breach does not remove the entire supply. Explosions can also drive large, hot fragments or spall through compartments, creating a different hazard from the original hole in the hull. Internal armor and Kevlar around combat-information centers, engineering spaces, and other vital areas are intended to stop those secondary fragments. Compartmentation absorbs the initial damage, while localized protection prevents its effects from reaching the systems the ship most needs to survive and fight.
