A navy can be both a friend and a threat: its visible presence reassures partners while warning potential opponents. This role matters because naval combat can move quickly from an intact ship to catastrophic loss, with fewer intermediate outcomes than land warfare often presents. The horrors are also harder to see. A submarine crew may disappear with a sinking boat, while blast, fire, flooding, and heavy torpedoes can destroy whole compartments or sections of a surface ship. HMS Eskimo's lost bow and HMS Nubian's lost stern provide concrete examples of damage survived by their crews. Deterrence and reassurance aim to prevent a form of war whose human consequences are often hidden below decks or beneath the sea.
