South Korea must expand its navy to safeguard energy imports and trade routes

South Korea’s economy relies on oil and gas shipments that must traverse distant seas, making maritime security essential. While the navy has gained experience through the Cheonghae Unit and overseas drills, the author contends it lacks the capacity to defend merchant ships against high-intensity threats over prolonged periods. He stresses that U.S. deployments follow American strategic interests, so Seoul cannot assume its energy routes will always be a top priority for Washington.

Developing a robust fleet will involve not only new warships but also submarines, aircraft, logistics vessels, and the supporting infrastructure for maintenance and ammunition. Coordination with the shipping industry, clear legal rules and shared threat intelligence are also required. The piece concludes that decisions made now will shape South Korea’s ability to protect vital sea lanes for decades.
