What is a strategic purpose of maritime warfare?

Securing shipping lanes and trade routes is a fundamental strategic purpose of maritime warfare. In many conflicts, a nation's economic stability and military effectiveness can hinge on its ability to ensure the safe passage of commercial vessels, which carry essential goods, resources, and supplies.

Control over these critical waterways can prevent adversaries from disrupting trade, which is integral to maintaining a strong economy during wartime. Additionally, securing these routes enables a nation to project power and extend its influence globally. Given that a significant portion of international trade occurs via maritime transport, failure to protect shipping lanes can lead to significant economic and strategic disadvantages. Therefore, the emphasis on securing these vital channels underscores the importance of maritime warfare in both military strategy and national security planning.
