Presence ships create an escalation ladder

The Falklands example shows how replacing a routine Type 31 presence ship with a Type 26, Type 45, or Type 83 would signal that Britain had noticed a change and was raising its level of concern. The same logic appears in an interwar analogy: an Arethusa-class light cruiser represents low-key presence, a Town-class cruiser is harder to ignore, and a County-class heavy cruiser delivers an explicit warning. Renown, Repulse, or Hood would raise the stakes again, while a battle squadron would indicate still more serious intent. Force composition becomes a diplomatic language because the class of ship sent can matter as much as the number.
