How a navy expanded Pergamon's reach

How did building a navy help Pergamon expand its power in the Aegean in the late third and early second centuries BC?

It supplied strategic mobility and logistics, allowing forces to outflank opponents and reach coastal objectives.

In the late third and early second centuries BC, a navy gave Pergamon strategic mobility across the Aegean. Ships supported forces along the coast, supplied them, and opened routes for outflanking opponents. Simon Elliott's interpretation of Roman Britain provides a comparison: he places effective conquest at the point when the navy could sail around the island and reach all settlements of note.
