Is Control of the Sea Lanes Vital

Mahan’s Argument

Mahan’s argument focused on command of the sea and the need for a powerful and balanced fleet for maintaining strategic control of maritime chokepoints. A strong navy meant that one could deter potential adversaries, project power across the globe, and manage the sea lanes of trade.

Mahan thus advocated for decisive naval engagements as the primary means to destroy the enemy's fleet and secure maritime dominance. This argument was basically rooted in the belief that control of the sea was essential for influencing global trade routes and exerting international power. He stressed the importance of a strong, well-equipped navy, with battleships as the fleet's cornerstone, capable of both offensive and defensive operations. Additionally, Mahan underscored the strategic value of controlling key maritime chokepoints, such as straits and canals, to disrupt or dominate sea lines of communication.

In the context of modern great power competition, there are several advantages to Mahan's strategy. First, a strong navy acts as a good deterrent against adversaries by asserting global influence and showing that national interests are and will be protected. Command of the sea makes it so that the nation can project power worldwide and influence international affairs, both of which are important in a globalized world where maritime trade is much needed for a country’s economic stability.

However, there are some drawbacks to Mahanian principles in today's context that one should consider. First is the financial burden of building and maintaining a powerful navy as Mahan envisioned—such a cost is not insignificant. Second, in the era of advanced technology, the dominance of large battleships is challenged by new threats like missiles, lasers, cyber warfare, and even economic and psychological warfare. Mahan's strategy may also be less effective in asymmetric conflicts, where unconventional tactics are employed by non-state actors or smaller navies. Third, the global presence and operations of a large navy can have environmental concerns and cause political tensions with other nations.
