A navy is the branch of a country's armed forces that fights at sea, using ships, submarines, and naval aircraft. An army fights on land. Together with the air force, they form a nation's military, each specialising in a different environment: water, ground, and sky.

A navy defends a country's waters and coastline, protects shipping and trade routes, projects power far from home, and can launch operations from the sea. Its work includes patrolling, deterring threats, supporting allies, delivering aid, and, in wartime, fighting enemy vessels and forces.

Because most of the world is ocean and most trade travels by sea, a navy safeguards the routes and waters a nation depends on. It defends coastlines, deters aggression, and lets a country respond to crises far from home, making it central to national security.

Yes. 'Navy', short for navy blue, is a very dark blue named after the traditional uniforms of the British Royal Navy. So the same word can mean a nation's sea forces or the deep blue shade associated with their historic dress.
