Maritime defense refers to the strategies and measures taken to protect a nation's waters, ports, and maritime interests from threats such as piracy, smuggling, and military aggression. This involves the use of naval forces, surveillance systems, and international cooperation to ensure safe navigation and secure trade routes. Key components of maritime defense include the deployment of naval vessels, such as aircraft carriers and submarines, as well as the establishment of coast guard operations. Additionally, countries often engage in joint exercises and partnerships with allies to enhance their capabilities and respond effectively to maritime challenges.
