Naval defense refers to the strategies and measures taken to protect a nation's waters and maritime interests. This includes the use of ships, submarines, and aircraft to deter or respond to threats from other nations or non-state actors. A strong naval defense ensures the safety of trade routes and the security of coastal areas, making it essential for a country's overall defense strategy. Key components of naval defense include naval fleets, missile systems, and intelligence gathering. Countries often invest in advanced technology and training to enhance their naval capabilities. Effective naval defense not only protects a nation's assets but also contributes to global stability and peace.
