The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes , ferry troops , or attack other navies , ports or shore installations ) .

      The strategic task of the navy also may incorporate nuclear deterrence by use of nuclear missiles. Naval operations can be divided into riverine and coastal applications ( brown - sea water ) and applications in the open ocean (blue - sea water ), although the distinction is more about the strategic significance of the tactical or operational division.
