Navy

A military organization whose primary function is fighting at sea. Navies are composed of warships, auxiliary vessels, maintenance facilities on the shore, and, beginning in the twentieth century, ship-based airplanes. The earliest known specialized navies appeared in Greece in the fifth century b.c.e. For the following 2,000 years, technical restrictions kept naval operations close to shorelines. By the fifteenth century, however, the compass, gunpowder artillery, and improved sailing vessels had broadened the scope of naval warfare. The sixteenth century witnessed the advent of large, heavily armed men-of-war—the defenders of mercantilistic traffic. By the eighteenth century, European warships had shaken off the navigational safety of the coasts and were battling each other around the globe. Steam power and iron-clad warships came into their own during the last half of the nineteenth century. The basic form of the modern battleship was developed in the late nineteenth century: heavily armored, swiftly moving vessel armed with large, powerful, extremely accurate long-range guns.mgmh-rs-117820-156462.jpgmgmh-rs-117820-156463.jpg
