Surface ships make power visible without firing

Surface ships remain adaptable patrol and task-group assets as missiles and aircraft change the threats they face. Submarines derive much of their deterrent value from uncertainty about their location. Revealing one against a peer exposes it to aircraft and small surface forces, while using its weapons risks turning a crisis into a battle. A surface ship sacrifices no hidden advantage by being seen, so it can signal intent and maintain a presence without firing. Submarine warfare and sustained peacetime influence therefore demand different capabilities.
