What is naval: Definition and 15 Discussions

A navy, naval force, or maritime force is the branch of a nation's armed forces principally designated for naval and amphibious warfare; namely, lake-borne, riverine, littoral, or ocean-borne combat operations and related functions. It includes anything conducted by surface ships, amphibious ships, submarines, and seaborne aviation, as well as ancillary support, communications, training, and other fields. The strategic offensive role of a navy is projection of force into areas beyond a country's shores (for example, to protect sea-lanes, deter or confront piracy, ferry troops, or attack other navies, ports, or shore installations). The strategic defensive purpose of a navy is to frustrate seaborne projection-of-force by enemies. The strategic task of the navy also may incorporate nuclear deterrence by use of submarine-launched ballistic missiles. Naval operations can be broadly divided between riverine and littoral applications (brown-water navy), open-ocean applications (blue-water navy), and something in between (green-water navy), although these distinctions are more about strategic scope than tactical or operational division.

    Can military naval vessels easily survive any hurricane/typhoon?

    This question is for any naval military folk out there . . . Can naval vessels, from the largest aircraft carriers down to the smaller ships, easily survive severe ocean weather like hurricanes and typhoons? If so, do they even change their training schedules due to bad weather?

    Plotting the naval territory of a country

    OK, say we have the border of a country represented by a polygon, how do we obtain a new border which at every point has it's nearest point to the country at exactly say 10 miles from it? Is there an algorithm to do this or is it highly computational? It's not as simple as it first seems.
